A stroke is when blood stops flowing to the brain from a blood clot or a narrowing of an artery, thus resulting in a lack of oxygen to the brain and dying brain cells. Such an attack on the brain can have dire consequences.
If you have sudden numbness, confusion, dizziness or an intensely severe headache, you may be having a mini-stroke, and you need to see a Dr. immediately.
Some preventable things you can do:
- maintain normal blood pressure
- quit smoking
- treat heart disease if needed
- treat diabetes if needed
