A stroke – decrease in blood flow to the brain due to a clot or bleeding,is a medical emergency. And doctors often say “time is brain,” meaning the quicker you get treatment, the less likely it is that your brain tissue will be permanently damaged. About 80% of strokes are due to a clot and the rest are due to bleeding in the brain.
Stroke can cause double vision, blurred vision or loss of vision in one eye.But it may not be as well recognized as facial weakness, arm weakness, and speech problems.
A stroke can cause sudden confusion. For example, if you’re typing on your computer or having a conversation, you may suddenly have difficulty speaking, thinking, or understanding speech.
Weak arm or leg
When you’re having a stroke, it’s common for an arm or leg (or both) to suddenly go weak, numb, or to become paralyzed. Often the affected limb is on the side of the body opposite from where the stroke occurred in the brain.
If a severe headache develops suddenly with no known cause, you might be having a stroke. This headache may be accompanied by dizziness or vomiting.If you have a history of migraine headaches, it may be difficult to identify this symptom or vision problems as signs of stroke.
Sudden, one-sided facial weakness can be a sign of stroke.Emergency medical personnel will ask you to smile or show your teeth. If one side of your face sags or doesn’t move, that could mean you’re having a stroke.
Usually, hiccups are a minor nuisance.But when stroke affects the brain’s breathing center, it can trigger a sudden, protracted case of hiccups, more commonly in women.
Breathlessness or heart palpitations
Can’t catch your breath? Feel like your heart is racing or fluttering? A study of gender differences in stroke found that women are more likely to experience these kind of symptoms.
Fatigue or mental changes
A recent study of gender differences in ischemic stroke, the type caused by clots, found that women having a stroke were more likely than men to experience general weakness, fatigue, disorientation, and change in mental status.
Dizziness or loss of balance
If you are dizzy, nauseous or have trouble walking, people may think you’re intoxicated when, in fact, you’re having a stroke.
