[Balint syndrome as a result of a biparietal infarct. Neuropsychological analysis].

A case of Balint syndrome with bilateral parietal infarction is presented. Analysis shows the tight intrication of visual inattention and psychic gaze palsy. The deficit of visuo-manual adjustment is characterized by a fixed divergence between the target and the point where the patient places his hand, either in ballistic movements (classical optic ataxia), either in pursuit movements; for this reason, a simple disconnexion should not explain the classic optic ataxia. The discretion of aphasia allows the individualization of an anterograde and partially retrograde amnesia.
