The electrical stimulation seemed to enhance language training outcome in patients with chronic aphasia.Contextual repetition priming treatment is a technique which involves repeated repetition of names of pictures that are related semantically, phonologically, or are unrelated. Patients with impaired access to lexical-semantic representations show no long-term improvement in naming, but patients with good access to semantics show long-term benefits.Development of self-cueing strategies can also facilitate word retrieval. Patients identify core words that can be retrieved without struggle, and establish a relationship between cue words and words that begin with the same sound but cannot be retrieved. Patients then learn to use the cue word to facilitate word retrieval for the target object. Epidemiology
Many different populations can and do have anomia. For instance, deaf patients who have had a stroke can demonstrate semantic and phonological errors, much like hearing anomic patients. Researchers have called this subtype sign anomia.Multilingual patients typically experience anomia to a greater degree in just one of their fluent languages. However, evidence conflicts as to which language – first or second – is impacted 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 remaining symptoms can sometimes cause academic difficulties later on. Patients
This disorder may be extremely frustrating for people with and without the disorder.
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. Disconnection anomia results from the severing of connections between sensory and language cortices. Patients with disconnection anomia may exhibit modality-specific anomia, where the anomia is limited to a specific sensory modality, 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 patients anomia arises as a consequence of a disconnect between their visual cortex and language cortices.Patients with disconnection anomia may also exhibit callosal anomia, in which damage to the corpus callosum prevents sensory information from being transmitted between the two hemispheres of the brain. Therefore, when sensory information is unable to reach the hemisphere that is language-dominant (typically the left hemisphere in most individuals), the result is anomia. For instance, if patients with this 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.
