Young, Unexpected, and Ischemic: A Case Series of Varied Stroke Presentations

Abstract

Stroke in young adults represents a distinct clinical entity with diverse and often unconventional etiologies. Unlike older populations where atherosclerosis predominates, young stroke frequently arises from cardioembolic, genetic, autoimmune, or vascular structural causes. Early identification of these conditions is critical to prevent recurrence and long-term disability. This case series illustrates the varied clinical presentations, diagnostic challenges, and underlying mechanisms of stroke in young individuals. Our findings highlight the necessity for a thorough etiologic workup—including advanced imaging and targeted laboratory evaluation—to uncover rare but actionable causes. Improved recognition of these atypical contributors enables personalized management strategies and better functional outcomes in this vulnerable population.
