Study Notes
Stroke Overview
- A stroke, also known as a cerebral vascular accident (CVA) or brain attack, is an emergency condition that occurs when there is a sudden decrease in blood flow to a localized area of the brain, resulting in neurologic deficits.
Types of Strokes
- Strokes can be ischemic (when blood supply to a part of the brain is suddenly interrupted) or hemorrhagic (when a blood vessel ruptures, spilling blood into spaces surrounding neurons).
Small Vessel Strokes
- Small vessel strokes are small to very small infarcts in the deep, noncortical areas of the brain or the brainstem.
Manifestations of Stroke
- Manifestations of a stroke vary according to the cerebral artery involved and the area of the brain affected.
- Hemiplegia (paralysis of one side of the body) can occur, affecting the motor system.
- Other manifestations include:
- Hemiparesis (weakness of one side of the body)
- Dysarthria (difficulty speaking)
- Aphasia (difficulty with language)
- Apraxia (difficulty with movement)
- Gaze palsy (difficulty with eye movement)
- Visual field defects
- Dysphagia (difficulty swallowing)
- Hemianopia (difficulty with vision)
Importance of Early Detection
- Early detection of stroke is critical to reducing the extent of injury, complication, and morbidity.
Rehabilitation
- Physical therapy may help prevent contractures and improve muscle strength and coordination after a stroke.
