Brain stroke is defined as sudden onset neurological deficit or dysfunction manifested by sudden loss of function of body parts. It is the leading cause of the disability worldwide. Brain stroke is one of the leading cause of mortality as well.
Stroke may be due to any of the 2 following causes
The good news is that 80 percent of all strokes are preventable. It starts with managing key risk factors, including high blood pressure, cigarette smoking, atrial fibrillation and physical inactivity. More than half of all strokes are caused by uncontrolled hypertension or high blood pressure, making it the most important risk factor to control.
Medical treatments may be used to control high blood pressure and/or manage atrial fibrillation, carotid stenosis among high-risk patients. Those medicines include:
Yes. 85 percent of strokes are due to clot in the blood vessel supplying the brain. If you remove the clot within a specified period of time ( till 6-9 hrs) from stroke onset, we can expect recovery. Stroke due to rupture of blood vessel due to hypertension may not recover immediately
The physician can give a blood clot lysing ( melting) drug called thrombolytic drug ( usually t-PA). It can be given through the vein in the arm or selectively into the brain blood vessel after doing a brain angiogram. These methods are applicable if the patient reaches the comphrensive stroke centre within 4 and half hrs. For patients coming to a comphrensive stroke centre within 7-8 hrs after stroke, the clots in the major brain blood vessels can be removed using latest technologies including either basket like devices (stentriever technology) or suction devices. This is the latest technology in the treatment of ischemic stroke. It is being successfully and extensively used world over to treat acute stroke due to clots in major brain blood vessels ( References: Stroke. 2015 Oct;46(10):3020-35 )
