Difference in Clinical Features and Risk Factors of Ischemic Stroke Between Young and Elderly Adults: A Retrospective Observation from an Island Population

High body mass index, leukocyte count, uric acid, triglyceride levels, and low vitamin B12 levels are associated with ischemic stroke in young adults. Young adult patients had a higher prevalence of basal ganglia infarction, with a different subtype distribution from elderly patients. These findings highlight the importance of considering geographic specificity and age-related differences when developing stroke prevention and management strategies, formulating public health policies, and allocating medical resources for ischemic stroke.
