Sex differences in diagnosis of suspected minor cerebral ischemic events


  • Stroke mimic is more frequently diagnosed in women than men, with diagnostic revisions being common to both men and women.

Why this matters

  • Differentiating an acute cerebral ischemic event from a non-ischemic event (stroke mimic) can be challenging, particularly when symptoms are transient or minor; however, rapid and accurate diagnosis is vital for optimal treatment and secondary stroke prevention.

  • Awareness of the impact of sex differences on minor cerebrovascular events has important implications for diagnostic accuracy and outcomes in these patients, and highlights the value of standardized diagnostic tools including MRI, although visualization of TIA may not always be possible with this imaging modality.
