What is the reason for brain stroke

A hemorrhagic stroke is when there’s uncontrolled bleeding inside of your brain itself or in the space between your brain and its outer covering layer. This kind of stroke is especially severe and can happen and get worse quickly. Immediate medical attention is absolutely critical to avoid permanent brain damage or death. Overview What is a hemorrhagic stroke? A hemorrhagic (pronounced “hem-or-aj-ick”) stroke is a life-threatening medical condition that happens when a blood vessel in your brain ruptures and bleeds. This can disrupt the normal circulation of blood in your brain, starving some areas of oxygen. Accumulated blood also puts pressure on surrounding brain areas, damaging or destroying them. Hemorrhagic strokes are particularly dangerous because they cause severe symptoms that get worse quickly. Without fast medical attention, these strokes often cause permanent brain damage or even death. IMPORTANT: A stroke is a life-threatening emergency condition where every second counts. If you or someone with you has symptoms of a stroke, you need to IMMEDIATELY call 911 (or your local emergency services number). The longer it takes to receive care, the more likely a stroke will cause permanent brain damage or death. To recognize the warning signs of a stroke, remember to think FAST: • F is for face. Ask the person to smile. Look for a droop on one or both sides of their face, which is a sign of muscle weakness or paralysis. • A is for arm. A person having a stroke often ha...

WELLCOME DEPT. OF COGNITIVE NEUROLOGY / SCIENCE PHOTO LIBRARY / Getty Images Types of Stroke There are two main types of stroke that affect the brain. One is an ischemic stroke, which is due to a lack of blood flow to the affected area of the brain. The other is a hemorrhagic stroke that causes bleeding in the brain. Both types can lead to death to some of the nearby brain tissue. A transient ischemic attack, or TIA, causes symptoms that are similar to those of an ischemic stroke and have the same causes. The difference is that the TIA resolves quickly on its own and doesn't cause lasting damage. However, people who experience a TIA are at risk for another, perhaps more serious, event. It's important to reduce your stroke risk factors after a TIA occurs. Research suggests that electrolyte imbalances may be related, in part, to what type of stroke you've had. Among 300 people in one study, those who had an ischemic stroke also had a higher incidence of low sodium levels. People with hemorrhagic stroke were more likely to have high potassium levels. With stroke, it's important for healthcare providers to determine if there are electrolyte imbalances right away. When a stroke happens, this balance is disrupted in the brain. The brain's own acid-base balance can affect blood flow through the brain. Cells that are not receiving enough oxygen begin to become acidotic. The body mechanisms that help you to compensate for these changes, including your breathing, also may be impaire...

Stroke is the 5 th leading cause of death To help you understand the various factors associated with stroke, this article will discuss: • • • • What Causes a Stroke? A stroke is a neurological injury caused by disruption to the flow of blood within the brain. This can be caused by the bursting or clotting of an artery leading to or within the brain. There are two types of strokes (ischemic and hemorrhagic), and they are differentiated by their causes. A stroke is a life-threatening condition as brain cells cannot properly function without oxygen-rich blood. Swift medical treatment is necessary to restore the normal flow of blood within the brain, otherwise brain cells continue to die. Ischemic strokes are often treated with clot-dissolving drugs like aspirin or tPA. Hemorrhagic strokes often require surgery to repair the ruptured artery and relieve swelling within the skull. To Until the stroke has been treated, neurons (brain cells) are being damaged by the lack of oxygen-rich blood. This causes permanent brain damage in the affected areas. Fortunately, the brain is resilient and capable of healing through neuroplasticity. The rehabilitation process is designed to facilitate healing in the brain and restore as much function as possible. Now that you understand what causes a stroke, let’s discuss the early warning signs of stroke and when to seek help. Warning Signs of a Stroke The most effective way to minimize damage caused by a stroke is to identify stroke in its early ...

A transient ischemic attack (TIA), often referred to as a “ministroke,” occurs when part of the brain experiences a temporary lack of blood flow. This causes stroke-like symptoms that usually resolve within 24 hours. The main difference between a On the other hand, the symptoms and complications of a stroke can be more permanent. This is because, with a TIA, the blockage in the blood vessel usually resolves itself. However, since ministroke and Knowing the signs of a ministroke can help you get the treatment you need as early as possible. Because the symptoms of a ministroke and actual stroke are so similar, it’s almost impossible to tell if you are dealing with one or the other until you’re medically evaluated. One key factor to both sets of symptoms is that they happen suddenly. The most • numbness or weakness in your face, arms, or legs (especially if that numbness is on one side of the body) • sudden confusion • trouble speaking • trouble comprehending others • trouble seeing • trouble walking • loss of balance • • lack of coordination • a severe headache that doesn’t seem to have a cause • difficulty swallowing ( • facial droop If you or someone nearby suddenly starts experiencing any of these symptoms, call 911 or local emergency services, or go to the nearest emergency room as soon as possible. Blood clots are When there’s a clot in an artery that’s connected to the brain, blood can’t flow as freely as it needs to, which means the brain doesn’t get the oxygen it nee...
