[Right neglect with hemiasomatognosia, mental confusion, apraxia and agraphia without aphasia].

A 74 year-old woman was admitted with a right hemiplegia resulting from a left infarct that had totally destroyed the territory supplied by the middle and anterior cerebral arteries. The patient presented with anosognosia and hemiasomatognosia and negligence of the right half-field. She was aprosodic, not aphasic, and there was a severe apraxia and total agraphia. These neuropsychological disorders are discussed in relation to the contradictory data relative to the manual lateralization of the patient. Findings in this case of a "crossed apraxia" show that management of language and of the propositional gestures are not necessarily ensured by the same hemisphere. It also appears that manual preference may be a poor clue for interpretation in terms of functional lateralization.
