What is nominal aphasia?
Nominal aphasia is a form of aphasia (loss of language capability caused by brain damage) in which the subject has difficulty remembering or recognizing names which the subject should know well. The subject speaks fluently and grammatically and has normal comprehension, and the only deficit is trouble finding appropriate words. Subjects often use circumlocuations (speaking in a roundabout way) in order to express a certain word they cannot find the name for. Sometimes the subject can recall the name when given clues. Sufferers are often frustrated when they know they know the name, but cannot produce it. Anomic or nominal aphasia primarily influences an individual's ability to find the right name for a person or object. As a result, an object may be described rather than named. Hearing comprehension, repetition, reading, and writing are not affected, other than by this inability to find the right name. Speech is fluent, except for pauses as the individual tries to recall the right name. Physical symptoms are variable, and some individuals have no symptoms of one-sided weakness or sensory loss. |

More information on aphasia
What is aphasia? - Aphasia is a defect or loss of language function in which the comprehension or expression of words (or nonverbal equivalents of words) is impaired as a result of brain injury.
What is Broca's aphasia? - Broca's aphasia, also called motor aphasia, results from damage to the front portion or frontal lobe of the language-dominant area of the brain.
What is Wernicke's aphasia? - Wernicke's aphasia is caused by damage to the side portion or temporal lobe of the language-dominant area of the brain.
What is global aphasia? - Global aphasia is caused by widespread damage to the language areas of the left hemisphere. As a result, all basic language functions are affected.
What is nominal aphasia? - Nominal aphasia is a form of aphasia in which the subject has difficulty remembering or recognizing names which the subject should know well.
What is conduction aphasia? - Conduction aphasia is a relatively rare form of aphasia, caused by damage to the nerve fibres connecting Wernicke's and Broca's areas.
What causes aphasia? - Aphasia is caused by damage to one or more of the language areas of the brain. This damage affects one or more of the basic language functions.
How is aphasia diagnosed? - Commonly used tests to diagnose aphasia include the Boston Diagnostic Aphasia Examination, the Western Aphasia Battery, and possibly, the Porch Index of Speech Ability.
What's the treatment for aphasia? - Aphasia treatment therapy strives to improve an individual's ability to communicate by helping the person to use remaining abilities, to restore language abilities.
What's the prognosis of aphasia? - The outcome of aphasia is difficult to predict given the wide range of variability of the condition. The location of the injury is important and is clue to prognosis. |
