[Focal neuropsychological deterioration by posterior lobar atrophy (posterior cortical dementia)].
A right-handed 59 year old man who presented difficulties in the performance of complex acts (praxic) and spatial disorientation is described. Neurophysical exploration showed deterioration of the capacities linked to perceptive and spatial organization preserving the verbal capacities including the memory. After two years and a half of follow up practically no variation has been observed in his clinical manifestations with no implication of other superior mental function. CAT and MR findings revealed important posterior atrophy with an increase in the occipital loops. SPECT demonstrated cold images due to a bilateral parietal-temporal perfusion deficit. Discussion of the case leads to the needs of unifying the criteria and terminology for these focal degenerative processes.
