Which type of aphasia is characterized by limited speech output and effortful speech?

Broca's aphasia is characterized by limited speech output and effortful speech because it arises from damage to Broca's area, which is located in the left frontal lobe, an area responsible for language production. Individuals with Broca's aphasia typically understand speech relatively well and can often follow commands but struggle to produce spontaneous speech. Their speech tends to be non-fluent, telegraphic, and may consist of short phrases or single words, making it effortful as they have difficulty with grammar and forming complete sentences. This combination of limited output and difficulty in articulation is a hallmark of this type of aphasia.

In contrast, Wernicke's aphasia involves fluent but nonsensical speech, where individuals have poor comprehension and may not realize their speech is unmeaningful. Global aphasia presents with severe impairments in both expression and comprehension, leading to very limited communication abilities. Conduction aphasia is associated with difficulty in repeating words and sentences, despite relatively preserved comprehension and speech production.
