Headache & Pain
Headache associated with ischemic cerebrovascular disease
Headache in acute ischemic stroke is usually unspecific and unilateral, and can be abrupt or gradual in onset. Sentinel headache can occur hours or days prior to an ischemic stroke, and late-onset headache can start days or weeks after stroke. Headache can also occur with atherothrombosis, cerebral embolism, and small vessel disease, and is most likely due to electrochemical or mechanical stimulation of the trigeminovascular system.
