The clinical manifestations of Broca’s aphasia include: 1) oral expression disorder. In mild cases, the patient’s spoken language is slightly abnormal, with occasional omission of words. In severe cases, the patient may not be able to speak at all, only grunts, or only “yes” or “no”. The degree of impairment varies from case to case and is related to the duration of the disease and the degree of aphasia. 3. Repetition is abnormal, but better than spontaneous conversation, and repetition may slightly improve articulation difficulties. 3.Naming difficulty, but better than spontaneous conversation, such as the examination prompted “tooth–” (referring to toothbrush), the patient can say “toothbrush”. 4.Most Broca’s aphasic patients have difficulty in reading aloud, and their understanding of words is relatively better, but there are also obstacles. 5.Writing is not normal. Most Broca’s aphasic patients have right hemiplegia and write with their left hand, but the left hand writing is worse than that of non-aphasic patients. Not only do they write awkwardly and with sloppy strokes, they may also have dysgraphia and may also have mirror image writing. 6. It is not only difficult to dictate, but also to copy. It is more difficult to write complete statements, or to write statements without grammatical words, or to write sentences with wrong structure.
