Transient cerebral ischemia

Transient cerebral ischemia, commonly referred to as a transient ischemic attack (TIA), is a brief episode of temporary neurological dysfunction affecting the central nervous system, particularly the brain, due to acute, focal hypoperfusion

Transient cerebral ischemia, commonly referred to as a transient ischemic attack (TIA), is a brief episode of temporary neurological dysfunction affecting the central nervous system, particularly the brain, due to acute, focal hypoperfusion Pathophysiologically, it occurs when localized cerebral blood flow is abruptly interrupted by thromboembolism or arterial stenosis without causing persistent cellular death or acute tissue infarction

Pathophysiologically, it occurs when localized cerebral blood flow is abruptly interrupted by thromboembolism or arterial stenosis without causing persistent cellular death or acute tissue infarction It is most frequently encountered in adults with underlying vascular risk factors, including hypertension, atherosclerosis, and atrial fibrillation

It is most frequently encountered in adults with underlying vascular risk factors, including hypertension, atherosclerosis, and atrial fibrillation

Clinically, the condition is defined by the sudden onset of focal neurological deficits—such as unilateral weakness, sensory loss, visual disturbances, or dysphasia—that fully resolve, serving as a critical warning state for impending ischemic stroke
