Working Memory Impairment in Transient Ischaemic Attack: N-back as a Sensitive Measure for Detection.

Background: Transient ischaemic attack (TIA) can lead to lasting changes in brain structure and function resulting in cognitive impairment. Cognitive screening tools may lack sensitivity for detecting cognitive impairments, particularly executive function, which tends to be the earliest affected domain in vascular cognitive impairment.

Aim: In this preliminary study, we examine a working memory (WMem) task as a sensitive measure of cognitive impairment in TIA.
