A form of aphasia where there is difficulty naming familiar objects (also known as anomic aphasia). Usually caused by a lesion in the left inferior parietal lobe or left posterior temporal lobe. Speech is usually fluent and grammatically correct except for word retrieval problems which lead to pauses, substitution of nonspecific words ("thing") and "talking around" missing words.

an isolated nominal aphasia is quite rare. to complicate matters, naming difficulty is often an early sign in all types of aphasias.
