[Graphomania. Compulsive graphic activity as a manifestation of fronto-callosal glioma].

The presenting symptomatology in a case of fronto-callosal glioma were affective indifference, severe disorders of attention and dynamic aphasia with marked reduction in spoken expression. Spontaneous and induced writing were abundant and incoercible. Their meticulous production and formal correction contrasted with its semantic incoherence. This behavior is comparable with that of the compulsive activity that may result from pallidal lesions or bilateral frontal lesions. The term graphomania is proposed to distinguish this behavior from echographia and hypergraphism.
