[ { "from": "human", "value": "What is (are) Stroke?" }, { "from": "gpt", "value": "Stroke -- A Serious Event A stroke is serious, just like a heart attack. Each year in the United States, approximately 795,000 people have a stroke. About 610,000 of these are first or new strokes. On average, one American dies from stroke every four minutes. Stroke is the fourth leading cause of death in the United States, and causes more serious long-term disabilities than any other disease. Nearly three-quarters of all strokes occur in people over the age of 65. And the risk of having a stroke more than doubles each decade between the ages of 55 and 85. Stroke occurs in all age groups, in both sexes, and in all races in every country. It can even occur before birth, when the fetus is still in the womb. Learning about stroke can help you act in time to save a relative, neighbor, or friend. And making changes in your lifestyle can help you prevent stroke. What Is Stroke? A stroke is sometimes called a \"brain attack.\" Most often, stroke occurs when blood flow to the brain stops because it is blocked by a clot. When this happens, the brain cells in the immediate area begin to die. Some brain cells die because they stop getting the oxygen and nutrients they need to function. Other brain cells die because they are damaged by sudden bleeding into or around the brain. The brain cells that don't die immediately remain at risk for death. These cells can linger in a compromised or weakened state for several hours. With timely treatment, these cells can be saved. New treatments are available that greatly reduce the damage caused by a stroke. But you need to arrive at the hospital as soon as possible after symptoms start to prevent disability and to greatly improve your chances for recovery. Knowing stroke symptoms, calling 911 immediately, and getting to a hospital as quickly as possible are critical. Ischemic Stroke There are two kinds of stroke. The most common kind of stroke is called ischemic stroke. It accounts for approximately 80 percent of all strokes. An ischemic stroke is caused by a blood clot that blocks or plugs a blood vessel supplying blood to the brain. Blockages that cause ischemic strokes stem from three conditions: - the formation of a clot within a blood vessel of the brain or neck, called thrombosis\n- the movement of a clot from another part of the body, such as from the heart to the neck or brain, called an embolism\n- a severe narrowing of an artery (stenosis) in or leading to the brain, due to fatty deposits lining the blood vessel walls. the formation of a clot within a blood vessel of the brain or neck, called thrombosis the movement of a clot from another part of the body, such as from the heart to the neck or brain, called an embolism a severe narrowing of an artery (stenosis) in or leading to the brain, due to fatty deposits lining the blood vessel walls. Hemorrhagic Stroke The other kind of stroke is called hemorrhagic stroke. A hemorrhagic stroke is caused by a blood vessel that breaks and bleeds into the brain. One common cause of a hemorrhagic stroke is a bleeding aneurysm. An aneurysm is a weak or thin spot on an artery wall. Over time, these weak spots stretch or balloon out due to high blood pressure. The thin walls of these ballooning aneurysms can rupture and spill blood into the space surrounding brain cells. Artery walls can also break open because they become encrusted, or covered with fatty deposits called plaque, eventually lose their elasticity and become brittle, thin, and prone to cracking. Hypertension, or high blood pressure, increases the risk that a brittle artery wall will give way and release blood into the surrounding brain tissue." } ]

[ { "from": "human", "value": "What are the symptoms of Stroke?" }, { "from": "gpt", "value": "Know the Signs Knowing the warning signs of stroke and controlling stroke's risk factors can lower your risk of death or disability. If you suffer a stroke, you may not realize it at first. The people around you might not know it, either. Your family, friends, or neighbors may think you are unaware or confused. You may not be able to call 911 on your own. That's why everyone should know the signs of stroke and know how to act fast. Warning signs are clues your body sends to tell you that your brain is not receiving enough oxygen. If you observe one or more of the following signs of a stroke or \"brain attack,\" don't wait. Call 911 right away! Common Signs of Stroke These are warning signs of a stroke: - sudden numbness or weakness of the face, arm, or leg, especially on one side of the body\n- sudden confusion, trouble speaking or understanding\n- sudden trouble seeing in one or both eyes\n- sudden trouble walking, dizziness, loss of balance or coordination\n- sudden severe headache with no known cause. sudden numbness or weakness of the face, arm, or leg, especially on one side of the body sudden confusion, trouble speaking or understanding sudden trouble seeing in one or both eyes sudden trouble walking, dizziness, loss of balance or coordination sudden severe headache with no known cause. Other danger signs that may occur include double vision, drowsiness, and nausea or vomiting. Don't Ignore \"Mini-Strokes\" Sometimes the warning signs of stroke may last only a few moments and then disappear. These brief episodes, known as transient ischemic attacks or TIAs, are sometimes called \"mini-strokes.\" Although brief, TIAs identify an underlying serious condition that isn't going away without medical help. Unfortunately, since they clear up, many people ignore them. Don't ignore them. Heeding them can save your life. Why It's Important To Act Fast Stroke is a medical emergency. Every minute counts when someone is having a stroke. The longer blood flow is cut off to the brain, the greater the damage. Immediate treatment can save peoples lives and enhance their chances for successful recovery. Ischemic strokes, the most common type of strokes, can be treated with a drug called t-PA that dissolves blood clots obstructing blood flow to the brain. The window of opportunity to start treating stroke patients is three hours, but to be evaluated and receive treatment, patients need to get to the hospital within 60 minutes. What Should You Do? Don't wait for the symptoms of stroke to improve or worsen. If you believe you are having a stroke, call 911 immediately. Making the decision to call for medical help can make the difference in avoiding a lifelong disability and in greatly improving your chances for recovery. If you observe someone having a stroke if he or she suddenly loses the ability to speak, or move an arm or leg on one side, or experiences facial paralysis on one side call 911 immediately." } ]

[ { "from": "human", "value": "Who is at risk for Stroke??" }, { "from": "gpt", "value": "A risk factor is a condition or behavior that increases your chances of getting a disease. Having a risk factor for stroke doesn't mean you'll have a stroke. On the other hand, not having a risk factor doesn't mean you'll avoid a stroke. But your risk of stroke grows as the number and severity of risk factors increase. These risk factors for stroke cannot be changed by medical treatment or lifestyle changes. - Age. Although stroke risk increases with age, stroke can occur at any age. Recent studies have found that stroke rates among people under 55 grew from 13 percent in 1993-1994, to 19 percent in 2005. Experts speculate the increase may be due to a rise in risk factors such as diabetes, obesity, and high cholesterol. Age. Although stroke risk increases with age, stroke can occur at any age.

Stroke seems to run in some families. Several factors may contribute to familial stroke. Members of a family might have a genetic tendency for stroke risk factors, such as an inherited predisposition for high blood pressure (hypertension) or diabetes. The influence of a common lifestyle among family members could also contribute to familial stroke. Family history of stroke. Stroke seems to run in some families.

High Blood Pressure High blood pressure, also called hypertension, is by far the most potent risk factor for stroke. If your blood pressure is high, you and your doctor need to work out an individual strategy to bring it down to the normal range. Here are some ways to reduce blood pressure: - Maintain proper weight.\n- Avoid drugs known to raise blood pressure.\n- Cut down on salt.\n- Eat fruits and vegetables to increase potassium in your diet.\n- Exercise more. Maintain proper weight. Avoid drugs known to raise blood pressure. Cut down on salt. Eat fruits and vegetables to increase potassium in your diet. Exercise more. Your doctor may prescribe medicines that help lower blood pressure. Controlling blood pressure will also help you avoid heart disease, diabetes, and kidney failure. Smoking Cigarette smoking has been linked to the buildup of fatty substances in the carotid artery, the main neck artery supplying blood to the brain. Blockage of this artery is the leading cause of stroke in Americans. Also, nicotine raises blood pressure, carbon monoxide reduces the amount of oxygen your blood can carry to the brain, and cigarette smoke makes your blood thicker and more likely to clot. Your doctor can recommend programs and medications that may help you quit smoking. By quitting -- at any age -- you also reduce your risk of lung disease, heart disease, and a number of cancers including lung cancer. Heart Disease Heart disease, including common heart disorders such as coronary artery disease, valve defects, irregular heart beat, and enlargement of one of the heart's chambers, can result in blood clots that may break loose and block vessels in or leading to the brain. The most common blood vessel disease, caused by the buildup of fatty deposits in the arteries, is called atherosclerosis, also known as hardening of the arteries. Your doctor will treat your heart disease and may also prescribe medication, such as aspirin, to help prevent the formation of clots. Your doctor may recommend surgery to clean out a clogged neck artery if you match a particular risk profile. High Blood Cholesterol A high level of total cholesterol in the blood is a major risk factor for heart disease, which raises your risk of stroke. Your doctor may recommend changes in your diet or medicines to lower your cholesterol. Warning Signs or History of Stroke Experiencing warning signs and having a history of stroke are also risk factors for stroke. Transient ischemic attacks, or TIAs, are brief episodes of stroke warning signs that may last only a few moments and then go away. If you experience a TIA, get help at once. Call 911. If you have had a stroke in the past, it's important to reduce your risk of a second stroke. Your brain helps you recover from a stroke by drawing on body systems that now do double duty. That means a second stroke can be twice as bad. Diabetes Having diabetes is another risk factor for stroke. You may think this disorder affects only the body's ability to use sugar, or glucose. But it also causes destructive changes in the blood vessels throughout the body, including the brain. Also, if blood glucose levels are high at the time of a stroke, then brain damage is usually more severe and extensive than when blood glucose is well-controlled. Treating diabetes can delay the onset of complications that increase the risk of stroke." } ]

Diagnosing Stroke Physicians have several diagnostic techniques and imaging tools to help diagnose stroke quickly and accurately. The first step in diagnosis is a short neurological examination, or an evaluation of the nervous system. When a possible stroke patient arrives at a hospital, a health care professional, usually a doctor or nurse, will ask the patient or a companion what happened and when the symptoms began. Blood tests, an electrocardiogram, and a brain scan such as computed tomography or CT, or magnetic resonance imaging or MRI, will often be done. Measuring Stroke Severity One test that helps doctors judge the severity of a stroke is the standardized NIH Stroke Scale, developed by the National Institute of Neurological Disorders and Stroke at the National Institutes of Health, or NIH. Health care professionals use the NIH Stroke Scale to measure a patient's neurological deficits by asking the patient to answer questions and to perform several physical and mental tests. Other scales include the Glasgow Coma Scale, the Hunt and Hess Scale, the Modified Rankin Scale, and the Barthel Index. Diagnostic Imaging: CT Scan Health care professionals also use a variety of imaging techniques to evaluate acute stroke patients. The most widely used is computed tomography or CT scan, sometimes pronounced CAT scan, which is comprised of a series of cross-sectional images of the head and brain. CT scans are sensitive for detecting hemorrhage and are therefore useful for differentiating hemorrhagic stroke, caused by bleeding in the brain, from ischemic stroke, caused by a blockage of blood flow to the brain. Hemorrhage is the primary reason for avoiding thrombolytic therapy (drugs that break up or dissolve blood clots), the only proven therapy for acute ischemic stroke. Because thrombolytic therapy might make a hemorrhagic stroke worse, doctors must confirm that the acute symptoms are not due to hemorrhage prior to giving the drug. A CT scan may show evidence of early ischemia an area of tissue that is dead or dying due to a loss of blood supply. Ischemic strokes generally show up on a CT scan about six to eight hours after the start of stroke symptoms. Though not as common in practice, CT scans also can be performed with a contrast agent to help visualize a blockage in the large arteries supplying the brain, or detect areas of decreased blood flow to the brain. Because CT is readily available at all hours at most major hospitals, produces images quickly, and is good for ruling out hemorrhage prior to starting thrombolytic therapy, CT is the most widely used diagnostic imaging technique for acute stroke. Diagnostic Imaging: MRI Scan Another imaging technique used in acute stroke patients is the magnetic resonance imaging or MRI scan. MRI uses magnetic fields to detect a variety of changes in the brain and blood vessels caused by a stroke. One effect of ischemic stroke is the slowing of water movement through the injured brain tissue. Because MRI can show this type of injury very soon after stroke symptoms start, MRI has proven useful for diagnosing acute ischemic stroke before it is visible on CT. MRI also allows doctors to visualize blockages in the arteries, identify sites of prior stroke, and create a stroke treatment and prevention plan. Differences Between CT and MRI Scans MRI and CT are equally accurate for determining when hemorrhage is present. The benefit of MRI over a CT scan is more accurate and earlier diagnosis of ischemic stroke, especially for smaller strokes and transient ischemic attacks (TIAs). MRI can be more sensitive than CT for detecting other types of neurological disorders that mimic the symptoms of stroke. However, MRI cannot be performed in patients with certain types of metallic or electronic implants, such as pacemakers for the heart. Although increasingly used in the emergency diagnosis of stroke, MRI is not immediately available at all hours in most hospitals, where CT is used for acute stroke diagnosis. MRI typically takes longer to perform than CT, and therefore may not be the first choice when minutes count." } ]

[ { "from": "human", "value": "what research (or clinical trials) is being done for Stroke?" }, { "from": "gpt", "value": "The National Institute of Neurological Disorders and Stroke sponsors a wide range of basic and clinical research aimed at finding better ways to prevent, diagnose, and treat stroke, and to restore functions lost as a result of stroke. Preventing Secondary Brain Damage Currently, scientists are studying the risk factors for stroke and the process of brain damage that results from stroke. Some brain damage may be secondary, occurring after the initial death of brain cells caused by the lack of blood flow to the brain tissue. This secondary brain damage results from a toxic reaction to the primary damage. Researchers are studying this toxic reaction and ways to prevent secondary injury to the brain. Scientists hope to develop neuroprotective agents, or drugs that protect the brain, to prevent this damage. Animal Studies Scientists are also conducting stroke studies in animals. By studying stroke in animals, researchers hope to get a better picture of what might be happening in human stroke patients. Scientists can also use animal models to test promising therapies for stroke. If a therapy proves helpful for animals, scientists can consider testing the therapy in humans. One promising area of animal research involves hibernation. The dramatic decrease of blood flow to the brain in hibernating animals is so extensive that it would kill a non-hibernating animal. If scientists can discover how animals hibernate without experiencing brain damage, they may discover ways to stop the brain damage associated with decreased blood flow in stroke patients. Another study used a vaccine that interferes with inflammation inside blood vessels to reduce the frequency and severity of strokes in animals with high blood pressure and a genetic predisposition to stroke. Researchers hope that the vaccine will work in humans and could be used to prevent many of the strokes that occur each year in people with high risk factors. Can the Brain Repair Itself? Scientists also are working to develop new and better ways to help the brain repair itself to restore important functions to stroke patients. New advances in imaging and rehabilitation have shown that the brain can compensate for functions lost as a result of stroke. When cells in an area of the brain responsible for a particular function die after a stroke, the patient becomes unable to perform that function. However, the brain's ability to learn and change, called plasticity, and its ability to rewire the connections between its nerve cells means that it can compensate for lost functions. One part of the brain can actually change functions and take up the more important functions of a disabled part. Clinical Trials Clinical trials are scientific studies using volunteers that give researchers a way to test medical advances in humans. Clinical trials test surgical devices and procedures, medications, and rehabilitation therapies. They also test methods to improve lifestyles and mental and social skills. Clinical trials may compare a new medical approach to a standard one that is already available or to a placebo that contains no active ingredients or to no intervention. Some clinical trials compare interventions that are already available to each other. When a new product or approach is being studied, it is not usually known whether it will be helpful, harmful, or no different than available alternatives (including no intervention). The investigators try to determine the safety and usefulness of the intervention by measuring certain outcomes in the participants. Scientists are using clinical trials to - develop new and more effective treatments for stroke\n- discover ways to restore blood flow to the brain after stroke\n- improve recovery after stroke\n- learn more about the risk factors for stroke. develop new and more effective treatments for stroke discover ways to restore blood flow to the brain after stroke improve recovery after stroke learn more about the risk factors for stroke.

[ { "from": "human", "value": "How to diagnose Stroke?" }, { "from": "gpt", "value": "Doctors have several techniques and imaging tools to help diagnose stroke quickly and accurately. The first step in diagnosis is a short neurological examination, or an evaluation of the nervous system. When a possible stroke patient arrives at a hospital, a health care professional, usually a doctor or nurse, will ask the patient or a companion what happened and when the symptoms began. Blood tests, an electrocardiogram, and a brain scan such as computed tomography (CT) or magnetic resonance imaging (MRI) will often be done." } ]

[ { "from": "human", "value": "What is (are) Stroke?" }, { "from": "gpt", "value": "One test that helps doctors judge the severity of a stroke is the standardized NIH Stroke Scale, developed by the National Institute of Neurological Disorders and Stroke at the National Institutes of Health, or NIH. Health care professionals use the NIH Stroke Scale to measure a patient's neurological deficits by asking the patient to answer questions and to perform several physical and mental tests. Other scales include the Glasgow Coma Scale, the Hunt and Hess Scale, the Modified Rankin Scale, and the Barthel Index." } ]

[ { "from": "human", "value": "What is (are) Stroke?" }, { "from": "gpt", "value": "The most commonly used imaging procedure is the computed tomography or CT scan, also known as a CAT scan. A CT scan is comprised of a series of cross-sectional images of the head and brain. Because it is readily available at all hours at most major hospitals, produces images quickly, and is good for ruling out hemorrhage prior to starting thrombolytic therapy, CT is the most widely used diagnostic imaging technique for acute stroke. A CT scan may show evidence of early ischemia an area of tissue that is dead or dying due to a loss of blood supply. Ischemic strokes generally show up on a CT scan about six to eight hours after the start of stroke symptoms." } ]

[ { "from": "human", "value": "What is (are) Stroke?" }, { "from": "gpt", "value": "Another imaging technique used for stroke patients is the magnetic resonance imaging or MRI scan. MRI uses magnetic fields to detect a variety of changes in the brain and blood vessels caused by a stroke. One effect of ischemic stroke is the slowing of water movement through the injured brain tissue. An MRI can show this type of damage very soon after the stroke symptoms start. MRI and CT are equally accurate for determining when hemorrhage is present. The benefit of MRI over a CT scan is more accurate and earlier diagnosis of ischemic stroke especially for smaller strokes and transient ischemic attacks (TIAs). Also, MRI can be more sensitive than CT for detecting other types of neurologic disorders that mimic the symptoms of stroke. However, MRI cannot be performed in patients with certain types of metallic or electronic implants, such as pacemakers for the heart. Although increasingly used in the emergency diagnosis of stroke, MRI is not immediately available at all hours in most hospitals, where CT is used for acute stroke diagnosis. Also, MRI typically takes longer to perform than CT, and therefore may not be the first choice when minutes count." } ]

[ { "from": "human", "value": "What are the treatments for Stroke?" }, { "from": "gpt", "value": "With stroke, treatment depends on the stage of the disease.

The most popular kinds of drugs to prevent or treat stroke are antithrombotics -- which include antiplatelet agents and anticoagulants -- and thrombolytics. Antithrombotics prevent the formation of blood clots that can become stuck in an artery of the brain and cause strokes. - In the case of stroke, doctors prescribe antiplatelet drugs mainly for prevention.

Injectable anticoagulants include heparin, enoxaparin (Lovenox), and dalteparin (Fragmin). Thrombolytic drugs halt the stroke by dissolving the blood clot that is blocking blood flow to the brain. Ischemic strokes -- the most common kind -- can be treated with thrombolytic drugs. But a person needs to be at the hospital as soon as possible after symptoms start to be evaluated and receive treatment. A thrombolytic drug known as t-PA can be effective if a person receives it intravenously (in a vein) within 3 hours after his or her stroke symptoms have started. Because there is such a narrow time window for giving t-PA, it is important to note the time any stroke symptoms appear. Since thrombolytic drugs can increase bleeding, t-PA should be used only after the doctor is certain that the patient has suffered an ischemic and not a hemorrhagic stroke. Neuroprotectants are medications or other treatments that protect the brain from secondary injury caused by stroke. Although the FDA (Food and Drug Administration) has not approved any neuroprotectants for use in stroke at this time, many have been tested or are being tested in clinical trials. Cooling of the brain (hypothermia) is beneficial for improving neurological function after a cardiac arrest." } ]

[ { "from": "human", "value": "what research (or clinical trials) is being done for Psoriasis?" }, { "from": "gpt", "value": "Scientists who are working to better understand and treat psoriasis are making headway in several different areas. The Role of T Cells Scientists believe that psoriasis occurs when white blood cells called T cells, which normally help fight infections, attack the bodys skin cells by mistake. Scientists are working to understand what causes these cells to go awry in people with psoriasis. Their hope is that by better understanding why T cells attack the bodys healthy skin tissue, they can develop better treatments to stop or prevent that damaging process. New Treatments Since discovering that T cells attack skin cells in psoriasis, researchers have been studying new treatments that quiet immune system reactions in the skin. Among these are treatments that block the activity of T cells or block cytokines (proteins that promote inflammation). If researchers find a way to target only the disease-causing immune reactions while leaving the rest of the immune system alone, resulting treatments could benefit psoriasis patients as well as those with other autoimmune diseases (when the immune system attacks the bodys own tissues). Currently there are a number of potential psoriasis treatments in clinical trials, including injections, pills, and topical ointments. Clinical trials are research studies with volunteers in which drugs are tested for the effectiveness and safety. All drugs must complete and pass this process before they can be approved by the FDA. Psoriasis Genes Because psoriasis is more common among people who have one or more family members with the disease, scientists have long suspected that genes are involved. A number of genetic loci specific locations on the genes have been associated with the development of psoriasis or the severity or progression of the disease. In 2012, scientists discovered the first gene to be directly linked to development of plaque psoriasis. Researchers continue to study the genetic aspects of psoriasis, and some studies are looking at the nervous system to determine the genes responsible for the circuitry that causes itching. Psoriasis-related Conditions Research in recent years has shown that people with psoriasis are more likely to develop other health problems, including problems with the heart and blood vessels. Research is continuing to examine links between psoriasis and other health problems. Scientists are working to understand how and why these diseases occur in people with psoriasis, with the hope that this understanding will lead to better treatments for both psoriasis and the related diseases. Stress Reduction Treatment For many people with psoriasis, life stresses cause the disease to worsen or become more active. Research suggests that stress is associated with the increased production of chemicals by the immune system that promote inflammation. The same chemicals may play a role in the anxiety and depression that is common in people with psoriasis. Researchers are studying the use of stress reduction techniques, along with medical treatment, in the hope that reducing stress will both lower anxiety and improve the skin lesions of psoriasis.

It is also found in some foods that come from animals. Cholesterol is found in all parts of your body. It plays a vital role in your body. It makes hormones, helps you digest food, and supports the workings of all the cells in your body. But your liver makes all the cholesterol that your body needs to do this. Lipoproteins and Cholesterol Cholesterol circulates in your blood stream. But it's fatty while your blood is watery. Just like oil and water, the two do not mix. As a result, cholesterol travels through your bloodstream in small packages called lipoproteins. The packages are made of fat (lipids) on the inside and proteins on the outside. Two kinds of lipoproteins carry cholesterol through your bloodstream. It's important to have healthy levels of both: - low-density lipoproteins (LDL)\n- high-density lipoproteins (HDL). low-density lipoproteins (LDL) high-density lipoproteins (HDL). What Does LDL Cholesterol Do? Low-density lipoproteins (LDL) carry cholesterol to all the cells in your body, including the arteries that supply blood to your heart. LDL cholesterol is sometimes called bad cholesterol because it can build up in the walls of your arteries. The higher the level of LDL cholesterol in your blood, the greater your chances of getting heart disease. What Does HDL Cholesterol Do? High-density lipoproteins (HDL) carry cholesterol away from the cells in your body. HDL cholesterol is sometimes called good cholesterol because it helps remove cholesterol from your artery walls. The liver then removes the cholesterol from your body. The higher your HDL cholesterol level, the lower your chances of getting heart disease. If Your Blood Cholesterol Is Too High Too much cholesterol in your blood is called high blood cholesterol. It can be serious. It increases your chances of having a heart attack or getting heart disease. When the cholesterol level in your blood is too high, it can build up in the walls of your arteries. This buildup of cholesterol is called plaque. Plaque Buildup Can Lead to - Artherosclerosis. Over time, the plaque can build up so much that it narrows your arteries. This is called atherosclerosis, or hardening of the arteries. It can slow down or block the flow of blood to your heart. Artherosclerosis. Over time, the plaque can build up so much that it narrows your arteries. This is called atherosclerosis, or hardening of the arteries. It can slow down or block the flow of blood to your heart. - Coronary Heart Disease (CHD). Artherosclerosis can occur in blood vessels anywhere in your body, including the ones that bring blood to your heart, called the coronary arteries. If plaque builds up in these arteries, the blood may not be able to bring enough oxygen to the heart muscle. This is called coronary heart disease (CHD). Coronary Heart Disease (CHD).

This blockage can cause a heart attack. Heart Attack. Some plaques have a thin covering, so they may rupture or break open. A blood clot can then form over the plaque. A clot can block the flow of blood through the artery. This blockage can cause a heart attack. Lowering Cholesterol Can Affect Plaque Lowering your cholesterol level reduces your chances of plaque rupturing and causing a heart attack. It may also slow down, reduce, or even stop plaque from building up. And it reduces your chances of dying from heart disease. High blood cholesterol itself does not cause symptoms, so many people don't know that they have it. It is important to find out what your cholesterol numbers are because if you have high blood cholesterol, lowering it reduces your chances of getting heart disease or having a heart attack." } ]

Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in the body's arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). Over time, plaque can harden and narrow the arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. P.A.D. usually affects the arteries in the legs, but it can also affect the arteries that carry blood from your heart to your head, arms, kidneys, and stomach. Blocked blood flow to your legs can cause pain and numbness. It also can raise your risk of getting an infection in the affected limbs. Your body may have a hard time fighting the infection. Why is P.A.D. Dangerous? Over time, the plaque may crack and cause blood clots to form. These blood clots can block arteries, causing pain, numbness, inflammation, and even permanent tissue damage in the affected part of the body. If severe enough, blocked blood flow can cause tissue death (also called gangrene.) In very serious cases, this can lead to leg amputation. P.A.D. currently affects 8 million to 12 million Americans. About 1 in every 20 Americans over the age of 50 has P.A.D. African Americans are more than twice as likely as Caucasians to have P.A.D. If you have P.A.D., your risk of coronary artery disease, heart attack, stroke, and transient ischemic attack (\"mini-stroke\") is much higher than in people without P.A.D. If you have coronary artery disease, you have a 1 in 3 chance of having blocked leg arteries. Although P.A.D. is serious, it is treatable.

For example, being exposed to drugs of abuse in youth, living in a community where drug use is prevalent, having untreated mental disorders, such as depression, or dealing with difficult transition periods such as retirement or loss of a spouse can all make an older adult more vulnerable to drug abuse. Prevention Requires Various Approaches Prevention efforts must focus on gaining a better understanding of the factors that promote illicit drug use in older adults. Prevention also includes finding ways to stop drug use before it worsens and leads to health problems, including addiction. Family members can play an important role by being aware of an older relatives well-being and possible drug abuse, and stepping in to help at an early stage, if necessary.

By age 80, more than half of all Americans either have a cataract or have had cataract surgery." } ]

[ { "from": "human", "value": "Who is at risk for Cataract??" }, { "from": "gpt", "value": "Age-related cataracts develop in two ways. - Clumps of protein reduce the sharpness of the image reaching the retina.\n- The clear lens slowly changes to a yellowish/brownish color, adding a brownish tint to vision. Clumps of protein reduce the sharpness of the image reaching the retina. The clear lens slowly changes to a yellowish/brownish color, adding a brownish tint to vision. Protein Clumpings Cloud the Lens The lens consists mostly of water and protein. When the protein clumps up, it clouds the lens and reduces the light that reaches the retina. The clouding may become severe enough to cause blurred vision. Most age-related cataracts develop from protein clumpings. When a cataract is small, the cloudiness affects only a small part of the lens. You may not notice any changes in your vision. Cataracts tend to grow slowly, so vision gets worse gradually. Over time, the cloudy area in the lens may get larger, and the cataract may increase in size. Seeing may become more difficult. Your vision may get duller or blurrier. Discoloration of the Lens Cataracts cause the lens to change to a yellowish/brownish color. As the clear lens slowly colors with age, your vision gradually may acquire a brownish shade. At first, the amount of tinting may be small and may not cause a vision problem. Over time, increased tinting may make it more difficult to read and perform other routine activities. This gradual change in the amount of tinting does not affect the sharpness of the image transmitted to the retina. If you have advanced lens discoloration, you may not be able to identify blues and purples. You may be wearing what you believe to be a pair of black socks, only to find out from friends that you are wearing purple socks. Risk Factors The risk of cataract increases as you get older. Other risk factors for cataract include - certain diseases like diabetes\n- personal behavior like smoking or alcohol use\n- environmental factors such as prolonged exposure to ultraviolet sunlight. certain diseases like diabetes personal behavior like smoking or alcohol use environmental factors such as prolonged exposure to ultraviolet sunlight." } ]

Get Regular Eye Exams Be sure to have regular comprehensive eye exams. If you are age 60 or older, you should have a comprehensive dilated eye exam at least once a year. Eye exams can help detect cataracts and other age-related eye problems at their earliest stages. In addition to cataract, your eye care professional can check for signs of age-related macular degeneration, glaucoma, and other vision disorders. For many eye diseases, early treatment may save your sight. For more on comprehensive eye exams, see the chapter on Symptoms and Detection. Quit Smoking Ask your doctor for help to stop smoking. Medications, counseling and other strategies are available to help you. Wear Sunglasses Ultraviolet light from the sun may contribute to the development of cataracts. Wear sunglasses that block ultraviolet B (UVB) rays when you're outdoors. Take Care of Other Health Problems Follow your treatment plan if you have diabetes or other medical conditions that can increase your risk of cataracts. Maintain a Healthy Weight If your current weight is a healthy one, work to maintain it by exercising most days of the week. If you're overweight or obese, work to lose weight slowly by reducing your calorie intake and increasing the amount of exercise you get each day. Choose a Healthy Diet Choose a healthy diet that includes plenty of fruits and vegetables. Adding a variety of colorful fruits and vegetables to your diet ensures that you're getting a lot of vitamins and nutrients. Fruits and vegetables are full of antioxidants, which in theory could prevent damage to your eye's lens. Studies haven't proven that antioxidants in pill form can prevent cataracts. But fruits and vegetables have many proven health benefits and are a safe way to increase the amount of vitamins in your diet.

Tests for Cataract Cataract is detected through a comprehensive eye exam that includes a visual acuity test, dilated eye exam, and tonometry. Tests for Cataract - The visual acuity test is an eye chart test that measures how well you see at various distances.\n- In the dilated eye exam, drops are placed in your eyes to widen, or dilate, the pupils. Your eye care professional uses a special magnifying lens to examine your retina and optic nerve for signs of damage and other eye problems.\n- In tonometry, an instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test. The visual acuity test is an eye chart test that measures how well you see at various distances.

Dealing with Symptoms The symptoms of early cataract may be improved with new eyeglasses, brighter lighting, anti-glare sunglasses, or magnifying lenses. If these measures do not help, surgery is the only effective treatment. Surgery involves removing the cloudy lens and replacing it with an artificial lens." } ]
