ABSTRACT
Motor forms of Aphasia are localised mostly in the anterior part of the speech area and sensory forms in the posterior part. The classical form of motor Aphasia is pre-eminently characterised by the loss of the power of spontaneous communication by means of language, spoken or written. The patient cannot utter anything except under the influence of emotion which would lead to swearing or expressions that have become automatic, such as ‘yes,’ ‘no.’ Severe cases of Sensory Aphasia cannot understand ordinary conversation at all, nor do what they are told, as they do not grasp the meaning of words or phrases. Likewise the ability of mastering writing and reading is impaired. Here the same mistakes occur as in speaking. Some patients are described as able to talk without difficulty in pronunciation, and with correct syntax and intonation. Verbal repetition and naming are not affected.
