What type of aphasia is characterized by slow, nonfluent speech?

The type of aphasia characterized by slow, nonfluent speech is expressive aphasia, also known as Broca's aphasia. This condition typically arises from damage to the frontal region of the brain, particularly the Broca's area, which is responsible for speech production and language processing. Individuals with expressive aphasia often have difficulty forming complete sentences and may struggle to find the right words, leading to sparse, effortful speech. They are usually aware of their communication difficulties and can understand spoken and written language relatively well.

In contrast, Wernicke's aphasia is marked by fluent but nonsensical speech, with individuals often producing long sentences that may lack meaningful content. Conduction aphasia involves difficulties in repeating phrases and sentences despite generally understood language. Global aphasia represents a severe form of aphasia, affecting both comprehension and production, leading to very limited communication capabilities. Thus, expressive aphasia most accurately describes the condition of producing slow and nonfluent speech.
