What type of aphasia is most likely for a patient who is unable to use verbs, but has no other obvious language deficits?

Question

BlackTom AI · Accepted Answer

The question asks which type of aphasia is most likely when a patient cannot use verbs but has no other obvious language deficits.
Option a: Broca’s Aphasia. This is a nonfluent aphasia characterized by halting, effortful speech and agrammatism, with frequent omission of function words and verbs. While verbs can be affected, Broca’s aphasia typically involves broader production problems beyond just verb use, making this option less precise for the given presentation.
Option b: Wernicke’s Aphasia. This is a fluent aphasia with poor comprehension and often meaningless speech. Patients typically retain grammar structure but produce jargon and neologisms; this does not align with “unable to use verbs” as the defining deficit, so this choice is unlikely.
Option c: Transcortical Aphasia. This family includes motor and sensory variants where repetition is relatively preserved, but language deficits are usually broader than a sole verb retrieval problem. The description doesn’t fit the preservation/repetition pattern characteristic of transcortical types.
Option d: Global Aphasia. Global aphasia involves severe, widespread language impairment affecting expression, comprehension, and often repetition across modalities. It would not be limited to verb retrieval with otherwise normal language, so this is not a good match.
Option e: Anomic Aphasia. This type is marked by difficulty with word retrieval, especially for nouns and verbs, while fluent speech and comprehension are relatively preserved and repetition is intact. A specific inability to access verbs fits well with anomic aphasia, making this the most plausible diagnosis among the options.

In summary, while several aphasias can involve word-finding problems, the hallmark of anomic aphasia is selective word retrieval difficulty (including verbs) with preserved grammar, comprehension, and repetition, which aligns best with the described presentation.
