Study Notes
Ischemic Stroke Types
- Two types: Thrombotic and Embolic strokes.
Thrombotic Stroke
- Most commonly results from atherosclerosis.
- Often originates from the internal carotid near the bifurcation.
- Majority of strokes manifest as pale infarcts, primarily affecting the middle cerebral artery.
- Frequently preceded by transient ischemic attacks (TIA).
- Characterized by occlusion of the middle cerebral artery.
- Clinical manifestations include contralateral hemiparesis, sensory loss, expressive aphasia (if Broca's area is involved), and visual field defects like homonymous hemianopia.
- A notable recovery rate is observed in the majority of patients.
Embolic Stroke
- Often originates from the left heart, particularly in conditions such as atrial fibrillation, rheumatic heart disease, and use of valvular prosthetics.
Hemorrhagic Stroke Types
- Two types: Intracerebral and Subarachnoid hemorrhages.
Intracerebral Hemorrhage
- Also known as Intraparenchymal Hemorrhage.
- Most commonly caused by hypertension.
- Can be due to ruptured Charcot-Bouchard microaneurysms linked to chronic hypertension.
- Commonly occurs in the basal ganglia, thalamus, and pons.
- High mortality rate, estimated between 30%-40%.
Subarachnoid Hemorrhage
- Defined as bleeding in the subarachnoid space.
- Etiology is often unknown.
- Frequently secondary to the rupture of congenital Berry Aneurysms in patients, typically women, aged 40-65 years.
- Congenital aneurysms are characterized by an absence of the internal elastic lamina and smooth muscle in cerebral vessel media.
- Common hemorrhage site is at the junction of the anterior communicating artery and the anterior cerebral artery.
- Clinical manifestations include severe headache ("worst headache I've ever had"), nausea/vomiting, stiff neck, light intolerance, and possible loss of consciousness (partial or complete).
