Anomic aphasia also known as dysnomianominal aphasiaand amnesic aphasia is a mild, fluent type of aphasia where an individual has word retrieval failures and cannot express the words they want to say particularly nouns and verbs. The most pervasive deficit in the aphasias is anomia. Some level of anomia is seen in all of the aphasias. Anomia can be genetic or caused by damage to various parts of the parietal lobe or the temporal lobe of the brain by an accident or strokeor a brain tumor.
Although the main causes are not specifically known, many researchers have found factors contributing to anomic aphasia. It is known that people with damage to the left hemisphere of the brain are more likely to have anomic aphasia.
Broca’s areathe speech production center in the brain, was linked to being the source for speech execution problems, with the use of functional magnetic resonance imaging fMRInow commonly used to study anomic patients. Although many experts have believed that damage to Broca’s area or Wernicke’s area are the main causes of anomia, current studies have shown that damage in the left parietal lobe is the epicenter of anomic aphasia.
Therefore, the original anomia model, which theorized afawia damage occurred on the surface of the brain in the grey matter was debunked, and it was found that the damage was in nomibal white matter deeper in the brain, on the left hemisphere. New data has shown that although the arcuate fascicles’ main function does not include connecting Wernicke’s area and Broca’s area, damage to the tract does create speech problems because the speech comprehension and speech production areas are connected by this tract.
Afasiaa best way to see if anomic aphasia has developed is by using verbal as well as imaging tests. The combination of the two tests seem to be most effective, since either test done alone may give nnominal positives or false negatives.
For example, the verbal test is used to see if there is a speech disorder, and whether it is a problem in speech production or in comprehension. Patients with Alzheimer’s disease have speech problems that are linked to dementia or nomonal aphasias which can include anomia. However, imaging cannot diagnose anomia on its own because the lesions may not be located deep enough to damage the white matter or damage the arcuate fasciculus.
However, anomic aphasia is very difficult to associate with a specific nomihal location in the brain. Therefore, the combination of speech tests and imaging tests has the highest sensitivity and specificity.
It is important to first do a hearing testin case the patient cannot clearly hear the words or sentences needed in the speech repetition test. However, to be completely sure, the test noominal given while a test subject is in an fMRI scanner, and the exact location of the lesions and areas activated by speech are pinpointed. Anomic aphasia anomia is a type of aphasia characterized by problems recalling words, names, and numbers. Speech is fluent and receptive language is not impaired in someone with anomic aphasia.
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. Sometimes subjects may know what to do with an object, but still not be able to give a name to the object. For example, if a subject is shown an orange and asked what it is called, the subject may be well aware that the object can be peeled and eaten, and may even be able to demonstrate this by actions or even verbal responses — however, they cannot recall that the object is called an “orange”.
Sometimes, when a person with this condition is multilingualthey might confuse the language they are speaking in trying to nokinal the right word inadvertent code-switching.
There is no method available to completely hominal anomic aphasia. However, there are affasia to help improve word-finding skills. Although a person with anomia may find it difficult to recall many types of words such as common nounsproper nounsverbsetc.
However, if that is not possible, then the patient is shown the same picture surrounded by words associated with the object or activity. The treatment shows an increase in word-finding during treatment; however, word identifying decreased two weeks after the rehabilitation period. The studies show that verbs are harder to recall or repeat, even with rehabilitation. Other methods in treating anomic aphasia afasix Circumlocution Induced Naming therapy CINwherein the patient niminal circumlocution to assist with his or her naming rather than just being told to name the item pictured after given nomunal sort of cue.
Results suggest afaia the patient does better in properly naming objects when undergoing this therapy because CIN strengthens the weakened link between semantics and phonology for patients with anomia, since they often know what an object is used for but cannot verbally name it. Anomia is often challenging for the families and friends of those suffering from it.
One way to overcome this is computer-based treatment models, effective especially when used with clinical therapy. Some of the patients received a drug known to help relieve symptoms of anomia levodopa while others received a placebo.
The researchers found that the drug had no significant effects on improvement with the treatment lists, but almost all of the patients improved after the CAT sessions. They concluded that this form of computerized treatment is effective in increasing naming abilities in anomic patients. Additionally, one study researched the effects of using “excitatory anodal transcranial direct current stimulation ” over the right temporo-parietal cortex, afadia brain area that seems to correlate to language.
The electrical stimulation seemed to enhance language training outcome in patients with chronic aphasia. Many different populations can nnominal do suffer from anomia. For instance, deaf patients who have suffered a stroke can demonstrate semantic and phonological errors, much like hearing nominql patients.
Researchers have called this subtype sign anomia. Bilingual patients typically experience anomia to a greater degree in just one of their fluent languages. However, there nomnial been conflicting evidence as to which language — first or second — suffers more.
Research on children with anomia has indicated that children who undergo treatment are, for the most part, able to gain back normal language abilities, aided by brain plasticity. However, longitudinal research on children with anomic aphasia due to head injury shows that even several years after the injury, some signs of deficient word retrieval are still observed. These nomlnal symptoms can sometimes cause academic difficulties later on. This disorder may be extremely frustrating for people no,inal and without the disorder.
Although the person 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. Although there are not many literary cases about anomic aphasia, there are many non-fiction books about living with aphasia.
Anomic aphasia – Wikipedia
It is the story of Sheila Hale’s husband, John Halea scholar who suffered a stroke and lost speech formation abilities. In her book, Afaeia Hale also explains the symptoms and mechanics behind aphasia and speech formation. She adds the emotional components of dealing with a person with aphasia and how to be patient with the speech and communication.
