[Global aphasia. The clinical picture and a consideration of the neurolinguistic structure (author's transl)].

Global aphasia is described as a unitary syndrome which is characterized by a severe impairment of all linguistic capabilities. Speech production is extremely limited and consists of stereotyped phrases, recurring utterances or a few isolated words which are usually neologistically distorted. The patients are unable to express their thoughts in a situationally adequate manner. Language comprehension is restricted to simple questions and commands. A clinical description of the syndrome is given and the neurolinguistic structure of the disorders is discussed.
