Summary of cognitive domains reported to be affected in studies of cognitive impairment after TIA, with examples of available evidence.

Affected Domain	Example of Evidence
Overall Executive Function	-Performance on executive function tasks decreased over 6-months after TIA in a prospective cohort study [81] -TIA/stroke patients scored worse than memory clinic patients on visuo-executive subtests of the MoCA in an analysis of TIA and cognitive decline cohorts [31]
Attention and Working Memory	-22.5-fold higher odds of impaired working memory and 6.8-fold higher odds of impaired attention versus controls in a case-control study with comprehensive neuropsychological assessment [2] -TIA/stroke patients scored worse than memory clinic patients on sustained attention subtests of the MoCA [31] -Attention improved over 6-months of follow-up (versus within 7 days post-event) in a prospective cohort [81]
Processing Speed	-7.1-fold higher odds of impaired processing speed versus controls in a case-control study [2]
Visual and Verbal Memory	-TIA subjects had lower scores on visual and verbal memory tests compared to non-TIA subjects on domain-specific neuropsychological testing in a case-control study [85]
Verbal Fluency	-TIA/stroke patients scored worse than memory clinic patients on verbal fluency subtests of the MoCA [31]
Cognitive-Motor Integration	-Impairments in motor cognitive-motor integration in more than half of TIA patients within 2-weeks of event with more than a quarter having deterioration in performance by 1-year in a small cohort [84]
