fr π₯π₯An ischemic stroke (the most common type of stroke) occurs when a blood vessel that feeds the brain gets blocked, usually from a blood clot.
When the blood supply to a part of the brain is cut off, some brain cells will begin to die. This can result in the loss of functions controlled by that part of the brain, such as walking or talking.
A hemorrhagic stroke occurs when a blood vessel within the brain bursts. This is most often caused by uncontrolled hypertension (high blood pressure).
Some effects of stroke are permanent if too many brain cells die after being starved of oxygen. These cells are never replaced.
The good news is that sometimes brain cells donβt die during stroke β instead, the damage is temporary. Over time, as injured cells repair themselves, previously impaired function improves. (In other cases, undamaged brain cells nearby may take over for the areas of the brain that were injured.)
Either way, strength may return, speech may get better and memory may improve. This recovery process is what stroke rehabilitation is all about.
When it comes to spotting stroke and getting help, the faster, the better. That's because prompt treatment may make the difference between life and death β or the difference between a full recovery and long-term disability. Use the letters in F.A.S.T to spot a stroke. F is for face drooping. A is for arm weakness. S is for speech difficulty. T is for time to call 911.
