[Anterior choroidal artery syndrome. Neuropsychological study of 4 cases].
A neuropsychological study was carried out in 4 cases of infarction in the territory of the anterior choroïdal artery. In 3 cases the lesions were on the right side. A syndrome of the minor hemisphere was present with severe visual neglect, constructional apraxia, alexia due to disorders of visuo-spatial strategy, anosognosia and motor impersistence. In the case with a left-sided lesion there was no neglect but a mild aphasia with impaired fluency, semantic paraphasias, perseveration and a decreased psycho-linguistic ability. The mechanisms of neglect in right-sided lesions are considered.
