Study Notes
Ischemic Stroke Overview
- Ischemic stroke results from the occlusion of a cerebral artery, with various risk factors including previous transient ischemic attacks (TIAs).
- Non-modifiable risk factors for ischemic stroke include age, race/ethnicity, and sex, while modifiable risk factors include cigarette smoking, hypertension (HTN), diabetes mellitus (DM), and atrial fibrillation (AF).
- Ischemic stroke is caused by the occlusion of a cerebral artery due to atherosclerosis, small artery damage, or cardiogenic emboli, which disrupts cerebral autoregulation and leads to ischemic penumbra and subsequent cellular damage.
- The pathophysiology of ischemic stroke involves hypoperfusion, excitotoxicity, oxidative stress, and cellular necrosis, leading to brain damage, disability, and potentially death.
- Ischemic stroke can be classified into large vessel thrombotic stroke, small vessel thrombotic stroke (lacunar stroke), cardioembolic stroke, and cryptogenic stroke (embolic stroke of undetermined source - ESUS).
- Large vessel thrombotic stroke primarily results from atherosclerosis in major cerebral arteries or the carotid artery, while small vessel thrombotic stroke involves occlusion of small arteries in the brain and presents with specific clinical syndromes.
- Cardioembolic stroke accounts for approximately 50% of ischemic strokes and is often associated with chronic atrial fibrillation (AF) and other sources of cerebral embolism.
- Cryptogenic stroke, also known as ESUS, refers to cerebral ischemia of unknown origin and is diagnosed in the absence of atherogenic and thrombogenic medical history.
- Transient ischemic attack (TIA) is characterized by transient symptoms without evidence of infarction, often preceding ischemic strokes and serving as a strong risk factor for stroke.
- Post-hospitalization rehabilitation and nursing home care for ischemic stroke patients can be expensive, and the condition can lead to various neurological symptoms and deficits, including aphasia, hemiplegia, sensory loss, hemineglect, and vertigo.
- The classification of ischemic stroke includes mechanisms, brain territory involvement, and symptoms, with specific manifestations related to anterior cerebral artery (ACA), middle cerebral artery (MCA), and posterior cerebral artery (PCA) territories.
- Symptom terminology review for ischemic stroke includes definitions of aphasia, contralateral, dysarthria, hemiparesis, hemiplegia, homonymous hemianopia, monoparesis, and vertigo, among others.
