What you need to know about Stroke
A stroke happens when blood flow to a part of your brain is cut off. Without the oxygen in blood, brain cells start dying within minutes.
It can also be defined as, a stroke occurs when the flow of blood to the brain is blocked. It is a medical emergency, because blood carries oxygen, and brain cells begin to die within a few minutes without it.
Types of stroke
- Ischemic stroke. In 8 out of 10 strokes, a blood vessel that takes blood to your brain gets plugged. It happens when fatty deposits in arteries break off and travel to the brain or when poor blood flow from an irregular heartbeat forms a blood clot
- Hemorrhagic (heh-more-raj-ik) strokes occur when a blood vessel in the brain breaks or ruptures. The result is blood seeping into the brain tissue, causing damage to brain cells.
- Tobacco: Smoking or chewing it raises your odds of a stroke. Nicotine makes your blood pressure go up. Cigarette smoke causes a fatty buildup in your main neck artery.
- Heart disease: This condition includes defective heart valves as well as atrial fibrillation, or irregular heartbeat, which causes a quarter of all strokes among the very elderly.
- High blood pressure: Your doctor may call it hypertension. It’s the biggest cause of strokes. If your blood pressure is typically 140/90 or higher, your doctor will discuss treatments with you.
- Lack of physical activity
- Heavy alcohol consumption
- Cardiovascular disease
Symptoms of stroke
Knowing the signs and symptoms of a stroke can help save lives.
The type and severity of stroke symptoms depend on the area of the brain that is affected.
- Sudden numbness, weakness, or inability to move the face, arm, or leg (especially on one side of the body)
- Trouble speaking or understanding speech
- Trouble seeing in one or both eyes
- Dizziness, trouble walking, or loss of balance or coordination
Effects of stroke
Stroke usually affects one side of the brain. Movement and sensation for one side of the body is controlled by the opposite side of the brain.
This means that if your stroke affected the left side of your brain, you will have problems with the right side of your body. If your stroke affected the right side of your brain, you will have problems with the left side of your body.
- Inability to walk and problems with coordination and balance (ataxia)
- Nausea and vomiting
- Right-sided weakness or paralysis and sensory impairment
- Problems with speech and understanding language (aphasia)
- Visual problems, including the inability to see the right visual field of each eye
- Impaired ability to do math or to organize, reason, and analyze items
- Behavioral changes, such as depression, cautiousness, and hesitancy
