Study Notes
Leading Causes of Death
- Stroke is the 3rd leading cause of death worldwide.
- Heart disease is the leading cause of death worldwide.
- The leading cause of death in stroke patients is heart failure.
Stroke
- Stroke is defined as a sudden neurological deficit caused by a focal disturbance of cerebral circulation.
- Ischemic stroke is caused by blockage of a blood vessel.
- Hemorrhagic stroke is more likely to undergo hemorrhagic transformation.
- The most important modifiable risk factor for stroke is hypertension.
- The most common cause of ischemic stroke is atherosclerosis.
Aneurysms
- A berry aneurysm is most likely to bleed.
- A berry aneurysm is most likely to cause an acute increase in intracranial pressure.
- A berry aneurysm is most likely to lead to re-bleeding in survivors.
- A berry aneurysm is most common in the anterior circulation, near arterial branch points.
Intracerebral Hemorrhage
- The most common location for intracerebral hemorrhage is the basal ganglia.
Lacunar Infarcts
- The most common location for lacunar infarcts is the internal capsule, pons, and thalamus.
- Lacunar infarcts are small, deep infarcts typically occurring in the deep brain structures.
- Cystic infarcts (lacunes) are most commonly found in the basal ganglia and thalamus.
Vascular Malformations
- The most common type of vascular malformation is an arteriovenous malformation.
- An arteriovenous malformation (AVM) is the primary cause of intracranial hemorrhage in patients with a vascular malformation.
Other
- The mechanism of vascular rupture in Charcot-Bouchard aneurysms is due to weakening of the blood vessel wall.
- In patients who survive intracerebral hemorrhage, the hematoma may resolve, stabilize, or even become a cyst.
- Global cerebral ischemia occurs due to insufficient blood flow to the entire brain.
- The most common cause of embolic arterial occlusion leading to ischemic stroke is atrial fibrillation.
Infarct Stages
- The stage of an infarct is characterized by pale soft regions of edema and loss of gray/white matter border is the early ischemic stage.
Neurological Deficits
- The neurological deficits that can result from a stroke include hemisensory defects, hemiparesis with weakness of one side of the body, homonymous hemianopia (loss of vision in one half field of view), aphasia, ataxia, neglect.
Risk Factors
- Less manageable risk factors for stroke include age, race, sex, and family history.
- More manageable risk factors for stroke include hypertension, diabetes, smoking, hyperlipidemia (high cholesterol), and atrial fibrillation.
