[Agrammatism in a patient with a lesion of the left temporal lobe. A case report].

A case of aphasia following left temporal lobe lesions is reported. The studied material was collected in a number of various tests including constructing of sentences and longer oral and written texts. A neurolioguistic analysis made possible an insight into the nature of the speech system in this case and characterization of disturbances in morphological aspects and their effect on syntaxis and coherent language. The observation lasting 4 years permitted an evaluation of changes taking place in language recovery during that time period.
