An evaluation of cognitive disorders after anterior choroidal artery infarction.
Anterior choroidal artery infarction (AChAI) can be the source of aphasia and spatial neglect, but we have no idea of the other possible cognitive disorders. Here, we investigated these disorders in a relatively large cohort of AChAI patients. Twenty patients with relatively recent infarction (left side: 13; mean delay = 47.4 days; 10 men; mean age = 59.6; mean education level, EL = 10.3) were included. We assessed nonspatial attention (alertness, Go Nogo, divided attention and visual vigilance from the computerized test TEA), spatial attention (bell test), language (BDAE) orientation (time, place), short-term memory (forward and backward digit spans, spatial span), executive functioning (WCST, TMT A and B, categorial evocation), delayed memory (Buschke verbal test, Rey figure test), and retrograde memory (questionnaire on famous events). The performance level was compared with that of 20 control subjects matched in age and EL. AChAI patients were impaired in several tests of attention (slowness, increase in omission and error rate), executive functioning (TMT B; categorical evocation) and delayed memory. Conversely, we found preservation of spatial attention, language, orientation, short-term memory, WCST, and retrograde memory. In conclusion, at the secondary phase post-stroke, these patients can present with moderate disorders of attention, memory and executive functioning, which are clearly less severe than what is usually observed following thalamic or cortical lesions.
