• B. Transient Ischemic Attack (TIA)
• C. Coma
• D. Seizure

Answer: (B)

The term for a temporary neurologic impairment due to reduced blood flow to the brain is Transient Ischemic Attack (TIA). A TIA is characterized by sudden, short-lived symptoms that mimic a stroke but resolve within 24 hours, typically within a few minutes to hours. During a TIA, there is a brief reduction in blood flow to a part of the brain, leading to transient neurological deficits.

Recognizing a TIA is crucial because it serves as a warning sign for a potential future stroke, allowing for early intervention and preventive measures. Unlike a stroke, where there is permanent damage to brain tissue due to prolonged interruption of blood flow, the effects of a TIA are temporary and reversible. Understanding this distinction is vital for appropriate medical response and patient education.
