364:, etc., many studies have shown that treatment for object words, or nouns, has shown promise in rehabilitation research. The treatment includes visual aids, such as pictures, and the patient is asked to identify the object or activity. However, if that is not possible, then the patient is shown the same picture surrounded by words associated with the object or activity. Throughout the process, positive encouragement is provided. The treatment shows an increase in word finding during treatment; however, word identifying decreased two weeks after the rehabilitation period. Therefore, it shows that rehabilitation effort needs to be continuous for word-finding abilities to improve from the baseline. The studies show that verbs are harder to recall or repeat, even with rehabilitation.

type of disconnection anomia hold an object in their left hand, this somatosensory information about the object would be sent to the right hemisphere of the brain, but then would be unable to reach the left hemisphere due to callosal damage. Thus, this somatosensory information would fail to be transmitted to language areas in the left hemisphere, in turn resulting in the inability to name the object in the left hand. In this example, the patient would have no problem with naming, if the test object were to be held in the right hand. This type of anomia may also arise as a consequence of a disconnect between sensory and language cortices.

292:, which can include anomia. The imaging test, mostly done using MRI scans, is ideal for lesion mapping or viewing deterioration in the brain. However, imaging cannot diagnose anomia on its own because the lesions may not be located deep enough to damage the white matter or the arcuate fasciculus. However, anomic aphasia is very difficult to associate with a specific lesion location in the brain. Therefore, the combination of speech tests and imaging tests has the highest

This test was administered to patients participating in a study in 2012, and researchers found that on the naming subtest of the AAT patients showed relevant naming difficulties and tended to substitute the words they could not produce with circumlocutions.
159:, such as hearing. For example, a patient who is perfectly capable of naming a target object when it is presented via certain sensory modalities like audition or touch, may be unable to name the same object when the object is presented visually. Thus, in such a case, the patient's anomia arises as a consequence of a disconnect between their visual cortex and language cortices.
149:. This is a disorder in which the meaning of words becomes lost. In patients with semantic anomia, a naming deficit is accompanied by a recognition deficit. Thus, unlike patients with word selection anomia, patients with semantic anomia are unable to select the correct object from a group of objects, even when provided with the name of the target object.

likely to have anomic aphasia. However, to be completely sure, the test is given while a test subject is in an fMRI scanner, and the exact location of the lesions and areas activated by speech are pinpointed. Few simpler or cheaper options are available, so lesion mapping and speech repetition tests are the main ways of diagnosing anomic aphasia.
329:(speaking in a roundabout way) to avoid a name they cannot recall or to express a certain word they cannot remember. Sometimes, the subject can recall the name when given clues. Additionally, patients are able to speak with correct grammar; the main problem is finding the appropriate word to identify an object or person.

Picture-naming tests, such as the

Although many experts have believed that damage to Broca's area or

The best way to see if anomic aphasia has developed is by using verbal and imaging tests. The combination seems to be most effective, since either test done alone may give false positives or false negatives. For example, the verbal test is used to see if a speech disorder presents, and whether the

This disorder may be extremely frustrating for people with and without the disorder. Although the persons with anomic aphasia may know the specific word, they may not be able to recall it and this can be very difficult for everyone in the conversation. Positive reinforcements are helpful.
