Stroke symptoms that worsen during a period of observation are characteristic of which condition?

Stroke symptoms that worsen during a period of observation are characteristic of which condition?

• A. RIND (Reversible Ischemic Neurological Deficit)
• B. Ischemic stroke
• C. SIE (Stroke in Evolution)
• D. TIA (Transient Ischemic Attack)

Answer: (C)

Stroke in Evolution is described when neurological deficits progressively worsen over hours after onset, reflecting ongoing ischemia as a thrombus propagates or edema expands the infarct. This pattern of gradually deteriorating or newly appearing deficits during observation distinguishes it from a transient ischemic attack, where symptoms completely resolve within a short time, and from RIND, where deficits persist longer than 24 hours but eventually fully recover. An ischemic stroke can start abruptly, but the explicit progressive course during monitoring is the hallmark of a stroke in evolution.
