Brain Stroke Symptoms and causes:
Trouble with speaking and understanding, you may experience confusion. You may slur your words or have difficulty understanding speech
- Paralysis or numbness of the face, arm or leg. You may develop sudden numbness, weakness or paralysis in your face, arm or leg, especially on one side of your body. Try to raise both your arms over your head at the same time. If one arm begins to fall, you may be having a stroke. Similarly, one side of your mouth may droop when you try to smile.
- Trouble with seeing in one or both eyes. You may suddenly have blurred or blackened vision in one or both eyes, and you may see double.
- Headache. A sudden, severe headache, which may be accompanied by vomiting, dizziness or altered consciousness, may indicate you’re having a stroke.
- Trouble with walking. You may stumble or experience sudden dizziness, loss of balance or loss of coordination.
if you notice any signs or symptoms of a stroke do the following
- Face. Ask the person to smile. Does one side of the face droop?
- Arms. Ask the person to raise both arms. Does one arm drift downward? Or is one arm unable to raise up?
- Speech. Ask the person to repeat a simple phrase. Is his or her speech slurred or strange?
If you observe any of these signs, call medical emergency number immediately
Don’t wait to see if symptoms go away. Every minute counts. The longer a stroke goes untreated, the greater the potential for brain damage and disability.
If you’re with someone you suspect is having a stroke, watch the person carefully while waiting for emergency assistance.
A stroke occurs when the blood supply to your brain is interrupted or reduced. This deprives your brain of oxygen and nutrients, which can cause your brain cells to die.
A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke). Some people may experience only a temporary disruption of blood flow to their brain (transient ischemic attack, or TIA).
There are three main kinds of stroke:
Transient ischemic attacks (TIAs), also referred to as mini-strokes
Many factors can increase your risk of a stroke. Some factors can also increase your chances of having a heart attack. Potentially treatable stroke risk factors include:
Lifestyle risk factors
- Being overweight or obese
- Physical inactivity
- Heavy or binge drinking
- Use of illicit drugs such as cocaine and methamphetamines
Medical risk factors
- High blood pressure — the risk of stroke begins to increase at blood pressure readings higher than 120/80 millimeters of mercury (mm Hg). Your doctor will help you decide on a target blood pressure based on your age, whether you have diabetes and other factors.
- Cigarette smoking or exposure to secondhand smoke.
- High cholesterol.
- Obstructive sleep apnea — a sleep disorder in which the oxygen level intermittently drops during the night.
- Cardiovascular disease, including heart failure, heart defects, heart infection or abnormal heart rhythm.
Other factors associated with a higher risk of stroke include:
- Personal or family history of stroke, heart attack or transient ischemic attack.
- Being age 55 or older.
- Race — African-Americans have a higher risk of stroke than do people of other races.
- Gender — Men have a higher risk of stroke than women. Women are usually older when they have strokes, and they’re more likely to die of strokes than are men. Also, they may have some risk from some birth control pills or hormone therapies that include estrogen, as well as from pregnancy and childbirth.
A stroke can sometimes cause temporary or permanent disabilities, depending on how long the brain lacks blood flow and which part was affected. Complications may include:
Paralysis or loss of muscle movement.
Difficulty talking or swallowing.
Memory loss or thinking difficulties
Preventing a stroke
- Eating a healthy diet
- Maintaining a healthy weight
- Exercise regularly
- Not smoking
- Avoiding alcohol or moderating consumption.
