stroke

How does a stroke happen? A stroke occurs when blood flow to a part of the brain is suddenly interrupted or cut off, which can lead to damage to brain cells. This interruption in blood flow usually occurs for two main reasons: ischemic stroke and hemorrhagic stroke. to the brain tissue can lead to motor, speech and cognitive disabilities... Types of stroke, checking the symptoms and causes of each... Stroke is divided into several main types: ischemic stroke, hemorrhagic stroke, stroke in sleep is a stroke attack and transient. or wake up with weakness on one side of the body.. It may be difficult to diagnose this type of stroke.. Symptoms such as severe headache, numbness, and sudden weakness on one side of the body are obvious symptoms of a stroke in sleep.. Risk factors for this type of stroke include high blood pressure, diabetes, and high cholesterol... ### Ischemic stroke Ischemic stroke occurs when blood flow to a part of the brain stops due to a blockage or blood clot. This type of stroke is the most common type of stroke and is usually caused by hardening of the arteries or blood clots. Symptoms of an ischemic stroke include numbness or weakness on one side of the body, impaired vision, or the risk of these types of stroke problems. Atherosclerosis, atrial fibrillation, and diabetes... ### Stroke hemorrhagic Hemorrhagic stroke is caused by the rupture of blood vessels in the brain and bleeding in the brain tissue... This type of stroke usually occurs due to high blood pressure, cerebral aneurysm or serious head injuries... The symptoms of hemorrhagic stroke include severe and sudden headache, loss of consciousness and weakness or paralysis on one side of the body... High blood pressure is one of the most important risk factors for this type of stroke... because it can lead to damage and weakening of the blood vessel wall... ### Attacks Transient ischemic A transient ischemic attack (TIA) is an emergency that has symptoms similar to an ischemic stroke.. But it is temporary and transitory... these attacks usually last for a few minutes to 24 hours and then recover... although these attacks themselves do not cause permanent damage to the brain; But they indicate a higher risk of a future full stroke. TIA symptoms can include numbness or weakness on one side of the body, slurred speech, and vision problems. Risk factors for transient ischemic attacks are similar to those of ischemic stroke and include high blood pressure, diabetes, and heart disease. Brain and affected area; Their severity and type are different... 1.... 1... paralysis or loss of muscle movement; One of the common side effects of a severe stroke is paralysis.. This condition may occur on one side of the body or only affect certain muscles such as facial or arm muscles. A stroke can affect the muscles of the mouth and throat, making it difficult for a person to speak, swallow, and even eat. They may have trouble saying words or be unable to understand what others are saying. Many people who experience a severe stroke may experience memory loss. emotional After a stroke, people may have trouble controlling their emotions and suffer from depression or anxiety. These emotional changes can significantly affect their quality of life. need for support; Many people who have experienced a stroke may become more socially withdrawn and need help with everyday tasks. This can lead to reduced self-confidence and difficulty taking care of themselves.. A silent stroke is a stroke that has no visible symptoms and people usually do not know about their stroke... Despite causing no detectable symptoms, a silent stroke puts you at risk for a stroke and subsequent stroke (TIA) and future strokes. In addition, those who have experienced a stroke may also be at risk for a silent stroke in the future. Silent strokes usually cause lesions that are detected using neuroimaging such as MRI....Silent strokes are estimated to occur five times more often than symptomatic strokes....The risk of silent stroke increases with age, but it may also affect younger adults and children, especially those with severe anemia. ### Stroke symptoms in women The symptoms of stroke in women are similar to men, except that there are other risk factors for stroke in women... For example, women who have a history of taking oral contraceptive pills are more prone to stroke, and women who develop preeclampsia during pregnancy will also be prone to stroke in the future. A number of specific recommendations have also been made for women, including aspirin use after the 11th week of pregnancy if there is a history of chronic hypertension and the use of blood pressure medications during pregnancy, especially if the systolic blood pressure is more than 150 mm Hg. Also, people who have already had preeclampsia should be followed up more carefully. What is the cause of stroke?.. Stroke is caused by certain reasons that we mention below: ### Cause of ischemic stroke - Atherosclerosis: the accumulation of fat and cholesterol in the walls of the arteries, which leads to narrowing and blockage of the arteries... - Blood clotting disorders: conditions that cause abnormal blood clots to form in the arteries... - Atrial fibrillation: a type of irregular heartbeat in which the risk increases and then increases... Heart defects: structural problems in the heart, such as atrial septal defects, which can restrict blood flow disrupt and lead to the formation of clots... - Microvascular ischemic disease: blockage of small blood vessels in the brain that reduces blood flow to brain tissues.... ### Cause of hemorrhagic stroke - High blood pressure: over time, high blood pressure can weaken the walls of blood vessels and cause them to rupture.... - Brain aneurysm: abnormal expansion in blood vessels that leads to bleeding if ruptured.... - Brain tumors: abnormal tumor growth can put pressure on blood vessels and lead to bleeding.. the head can; It leads to the rupture of blood vessels and bleeding in the brain... - blood thinners: excessive use of anticoagulants increases bleeding in the brain... ### Risk factors in stroke Ischemic and hemorrhagic strokes may occur for many reasons....Ischemic strokes, which occur due to blood clots, mostly occur for the following reasons: - Atherosclerosis - Blood coagulation disorders - Atrial fibrillation (especially when it occurs due to sleep apnea) - heart defects (atrial septal defect or interventricular wall defect) Microvascular ischemic disease (which can block smaller blood vessels in the brain) The main causes of hemorrhagic stroke are: - High blood pressure, especially in chronic cases - Aneurysm of cerebral vessels can sometimes lead to hemorrhagic strokes. - brain tumors - Diseases that cause weakening or abnormal changes in the blood vessels of the brain, such as Moyamoya disease. Can a stroke be treated? People who survive a stroke often face long-term problems from brain damage. Some people need a long period of rehabilitation before they can regain their former functional independence, while many never fully recover and need ongoing support after a stroke. One of the most important ways to treat a stroke is to help a person recover or adapt to the brain changes that have occurred.... Stroke rehabilitation is a major part of the recovery process of most people who have suffered a stroke. The following measures can help restore the person's strength in the rehabilitation process: - Speech therapy - Physiotherapy - occupational therapy - cognitive therapy Complications of stroke Some of the physical disabilities that can result from a stroke include muscle weakness, numbness, pressure ulcers, pneumonia, urinary incontinence, apraxia (inability to perform learned movements), problems with daily activities, loss of appetite, loss of speech, vision loss, and pain. If a stroke is severe enough or occurs in a specific location, such as parts of the brainstem, it can cause the patient to fall into a coma or die....Up to 10 percent of people have a seizure following a stroke, which usually occurs within a week after the stroke..The severity of the stroke increases the likelihood.> It is estimated that 15% of people experience urinary incontinence more than a year after a stroke. 50% of people experience decreased sexual function (sexual dysfunction) after a stroke. Emotional problems can also occur as complications of a stroke. These problems can include anxiety, panic attacks, blunted affect (inability to express feelings), mania, apathy, and psychosis.. Other problems may include a reduced ability to communicate emotions through facial expressions, body language, and voice. ### Complications of right stroke Effects of a right hemisphere stroke may include: - Weakness or paralysis of the left side and sensory disturbance - denial of paralysis or disorder and reduced insight of the person to the problems caused by stroke (this condition is called "left neglect") - Visual problems, including inability to see in the left visual field of both eyes - Spatial difficulties in perceiving depth or directions, such as up or down and forward or backward - Inability to identify or recognize body parts - Inability to understand maps and find objects, such as clothes or toiletries - memory problems - behavioral changes, such as lack of concern about situations, impulsivity, inappropriateness, and depression ### Complications of left stroke Effects of a left hemisphere stroke may include: - Weakness or paralysis of the right side and sensory disturbance - speech and language comprehension problems (aphasia) - Visual problems, including inability to see the proper field of view in both eyes - Impairment in the ability to do math or organize, reason and analyze things - behavioral changes, such as depression, caution and doubt - Disturbance in reading, writing and learning new information - memory problems Stroke treatment The treatment of stroke depends on whether it is ischemic or hemorrhagic stroke... In the following, we explain the treatment methods for each type of stroke: ### Ischemic stroke treatment In this type of stroke, the blood supply to a part of the brain is reduced or cut off... Treatment methods include: - emergency; A drug called a thrombolytic (such as tPA), which is used to quickly dissolve a blood clot and must be given within the first few hours after a stroke... - Emergency endovascular procedures.. Minimally invasive procedures involve using a catheter to access blood vessels and treat clots. They are injected.. Stenting: This procedure involves opening narrow vessels using a balloon and then placing a stent to keep the vessel open... ### Hemorrhagic stroke treatment In this type of stroke, bleeding occurs inside the brain or blood leaks outside the vessels. Treatment methods include: - Surgery: possible in severe cases.. there is a need for surgery to remove accumulated blood or repair damaged blood vessels.... - Coiling (endovascular embolization).. a procedure in which a catheter is used to insert small coils into the damaged blood vessels.. to stop bleeding.... - Removal of thin-walled blood vessels (AVM).. In cases where there are thin and weak blood vessels, they can be surgically removed - Stereotactic radiosurgery: a non-invasive method that uses targeted radiation to treat vascular abnormalities and reduce bleeding... ### Duration of stroke treatment The immediate treatment of a stroke includes the use of thrombolytic drugs or thrombectomy up to 24 hours after the stroke... If a person survives a stroke, depending on the amount of damage to the brain tissue, he will suffer a series of sensory and motor complications that must be minimized with treatments such as physical therapy and physical therapy. is low, the patient can recover after 2 to 4 months... some patients also experience recovery earlier than this time. However, it should be noted that in more severe cases, rehabilitation treatments can only increase the patient's quality of life, and some symptoms will remain in the person until the end of life. ### The best medicine for stroke patients Thrombolytic drugs (their name is a combination of the Greek words "thrombus" meaning "clot" and "lysis" meaning "loosening/dissolving") are an option in the first three hours after the onset of stroke symptoms. These drugs dissolve existing clots and save patients' lives. They can be used in ischemic strokes. Diagnosis and management of cerebral vein thrombosis (CVT) and its association with stroke Cerebral vein thrombosis (CVT) is a rare type of stroke in which a blood clot forms in the veins of the brain. This type of stroke often occurs in young people, pregnant women or those who use birth control pills, and people who have a tendency to form blood clots. 2024, stroke is still one of the leading causes of death in the United States and around the world.. Every year, approximately 795,000 people in the United States will experience a new or near-recurrent stroke.. 185,000 will experience a second stroke. A day of the number of deaths and Death due to stroke or its rate was not obtained.. Prevention of stroke To reduce the risk of stroke, it is necessary to follow some key points. Below are some of the most important methods of stroke prevention: - blood pressure control; High blood pressure is one of the main risk factors for mild or severe stroke. Regular and optimal control of blood pressure can help reduce the risk of stroke. - Reducing cholesterol and saturated fat in the diet. Eating less foods rich in saturated fat and cholesterol can help improve body health and reduce the risk of stroke. Too much alcohol can lead to high blood pressure and heart problems. Reducing or stopping alcohol consumption can help reduce the risk of stroke. Uncontrolled diabetes can cause serious complications for the cardiovascular system.. Blood sugar control can help reduce the risk of stroke.. - Maintaining a normal weight.. Overweight and obesity can; It leads to an increased risk of stroke. It is important to maintain a healthy weight through a balanced diet and regular exercise. A balanced diet rich in fruits and protein can contribute to the health of the body and reduce the risk of stroke... - treatment of obstructive sleep apnea; This sleep disorder can lead to an increase in blood pressure and heart problems.... Its treatment can improve the quality of sleep and reduce the risk of stroke.... - Not taking illegal drugs; The use of illegal drugs such as cocaine can have serious effects on cardiovascular health and increase the risk of stroke. Stroke is one of the critical medical conditions that is divided into two main types, ischemic and hemorrhagic. Among the common causes of stroke, we can mention high blood pressure, diabetes, heart diseases, high blood fat and vascular problems.. According to the sources, stroke complications may include movement disabilities, speech problems, cognitive disorders, and various emotional qualitative changes that can have a profound impact on a person's quality of life.. Methods.. Ischemic, emergency drugs such as thrombolytics are used to dissolve blood clots. Also, minimally invasive methods such as angioplasty and stenting and surgeries such as carotid endarterectomy are also used. Reducing the risks of stroke...
