Can be treated with tissue plasminogen activator (t-PA)
|
Anticlotting drug decreases tissue death in ischemic stroke but aggravates cell deat in
hemorrphagic stroke
|
Ischemia -deficiency of blood flow to the brain due to functional constriction of to the
actual obstruction of a blood vessel (causes about 80% of strokes)
{
If you sustained an injury and your blood vessels burst
