Final answer:
Expressive aphasia, also known as nonfluent aphasia, is a type of aphasia where an individual has difficulty in producing language but typically retains language comprehension. It is commonly associated with damage to Broca's area in the brain and is characterized by halting speech and grammatical errors.
Step-by-step explanation:
Expressive aphasia, also known as nonfluent aphasia, is a neurological condition characterized by the partial loss of the ability to produce language (spoken, manual, or written), although comprehension generally remains intact. It is often associated with damage to Broca's area, located in the lateral aspect of the frontal lobe of the brain.
Individuals with expressive aphasia may struggle with speech production, leading to broken or halting speech, and may also exhibit impairment in grammar. This condition is distinct from receptive aphasia, where the understanding of language is compromised, and conduction aphasia, which involves loss of the function to connect understanding speech with production of speech.
Assessment of language function and potential aphasia often includes evaluation of both expressive and receptive capabilities. In the case of expressive aphasia, speech can be nonfluent and the individual might show effortful speech, misarticulation of words, and reduced speech output.
