Stroke is a critical neurological disorder fundamentally caused by an interruption in the blood supply to the brain, leading to cell death and potential permanent damage (American Stroke Association [ASA], 2022). This paper meticulously evaluates the origins, characteristics, and clinical interventions associated with stroke.
Pathophysiology of Stroke
Causes of Stroke
Stroke arises primarily due to two distinct mechanisms: ischemic and hemorrhagic obstruction in cerebral blood flow.
Ischemic Stroke
Constituting approximately 87% of all stroke incidents, ischemic strokes transpire when there is a pronounced reduction or cessation of blood flow due to blood clots or other obstructions in arteries (Centers for Disease Control and Prevention [CDC], 2021). Clots can originate in any vascular region and travel to the cerebral vasculature.
Hemorrhagic Stroke
This variant occurs due to the leakage or rupture of cerebral blood vessels. Common precipitants include hypertension, aneurysms, and anticoagulant overutilization (ASA, 2022).
Transient Ischemic Attack (TIA) vs. Cerebrovascular Accidents (CVA)
Transient Ischemic Attack
A TIA is often dubbed a "mini-stroke," a transient, short-lived interruption of cerebral blood supply. Although inducing stroke-like symptoms, TIAs do not inflict permanent damage and often serve as harbingers of impending strokes (National Institute of Neurological Disorders and Stroke [NINDS], 2022).
Cerebrovascular Accidents
Contrarily, CVAs confer lasting, often perm
