What is a Stroke? - Oren Zarif - Stroke

A stroke is a life-threatening condition in which the brain's blood supply is impaired or stops. The brain's cells die. Transient ischaemic attacks, or mini-strokes, can last for minutes to 24 hours. They may also warn of an impending full stroke. If you notice any of these symptoms, contact emergency services immediately. Stroke is a condition that must be treated as soon as possible to minimize permanent brain damage and save the person's life.

During a stroke, nerve cells in brain tissue begin to die, and they cannot communicate. Once these cells die, they cannot perform their functions. A stroke can affect your ability to walk, talk, eat, see, read, and socialise. It can also lead to fatigue and problems with memory, learning, and understanding. Your doctor may prescribe medication to help you recover as quickly as possible. A rehabilitation program may also be helpful.

When a blood vessel in the brain becomes blocked, the blood supply to the brain is affected. This results in a lack of oxygen and nutrients to brain cells. Without adequate oxygen, brain cells start to die. Many strokes are treatable, though many of them can lead to permanent disability or even death. If you suspect you have a stroke, contact emergency services immediately. The sooner you receive treatment, the better your chances of recovering fully.

Medical treatment for a stroke is different for every person. Your doctor may give you blood thinners to prevent blood clots or reduce high blood pressure. Surgery is another option if a blood clot is preventing blood flow to the brain. This surgery usually takes place in the hospital emergency department. A doctor may also prescribe you a blood-thinning medicine, such as aspirin. Medications can also help prevent future strokes.

The American Heart Association and the Stroke Council recently updated the definition of stroke. This new definition includes an underlying condition called transient ischemic attack. The definition of stroke has changed a bit in the last 40 years, and it's crucial to update the definition of the disease. It is possible to prevent stroke, but you must be careful not to overdiagnose it. The sooner you diagnose it, the better your chances of recovery are.

Strokes are more common in men than in women. In general, older people are more likely to suffer from a stroke. People with high blood pressure, diabetes, or atrial fibrillation are at increased risk for stroke. Other risk factors include being overweight, consuming too much salt, and smoking. Stroke symptoms usually come on without warning. The person may also experience a change in alertness and may have trouble speaking or swallowing.

During a stroke, a blood vessel in the brain is plugged or ruptures. Because the brain cannot store oxygen, it relies on a network of blood vessels to get its oxygen supply. When a blood vessel breaks, the brain loses its oxygen supply and surrounding nerve cells are cut off from a constant supply of oxygen and nutrients. The affected tissue begins to die within three to four minutes of being cut off from oxygen and blood. There are two types of strokes: hemorrhagic and ischemic.
