[Broca's aphasia and apraxia of speech (author's transl)]

The paper shows that the aphasic syndrome originally described by Paul Broca corresponds to what is now called anarthria or apraxia of speech rather than to the nosological entity which nowadays goes by the name of Broca's aphasia. The paper further endeavours to demonstrate that the output difficulties of anarthric patients are different from those of patients with Broca's aphasia, and it suggests a number of criteria to discriminate between anarthria and Broca's aphasia (Acta neurol belg., 1982, 82, 80-90).
