What characterizes the speech of individuals with Wernicke's aphasia?

Wernicke's aphasia is characterized by speech that is fluent but often nonsensical or devoid of meaningful content. Individuals with this type of aphasia typically produce long, rambling sentences that contain grammatical structures and a normal rhythm, making their speech sound fluent. However, the vocabulary they use may be inappropriate or unrelated to the topic, making communication ineffective. They often have difficulty with comprehension and may not realize that their speech lacks meaning. This is distinct from other forms of aphasia, such as Broca's aphasia, where speech is effortful and agrammatic. In Wernicke's aphasia, the fluency of speech is preserved, but the content is impaired, leading to communication challenges despite a seemingly normal speech flow.
