Transcortical Motor Aphasia is a nonfluent aphasia characterized by limited spontaneous speech, preserved repetition, and relatively good comprehension. It is typically caused by damage to the frontal lobe areas surrounding Broca’s area, disrupting speech initiation but sparing core language comprehension. Individuals with this condition may respond to questions with brief phrases or echolalia and often require prompting to initiate verbal output. Right-sided weakness may accompany the language symptoms due to the lesion’s frontal location. SLPs target initiation strategies and structured language tasks to improve voluntary speech.
