Bilingual Aphasia with Parallel Recovery

Bilingualism is often used in science and in general terms to refer to knowledge and / or use in both languages, but the specific content of the definition is widely debated (eg Altariba and Heredia, 2008; De Groot & Kroll, 1997; Grosjean, 2010). In fact, it is estimated that more than one third of the world's population (Grosjean, 2010) to 2/3 (Walraff, 2000) often uses multiple languages ​​in daily communication environments. Considering this global linguistic feature, it has been suggested that people who are difficult to communicate after a stroke may become increasingly bilingual (Ansaldo, Marchotte, Scherer, & Raboyeau, 2008; Centeno, 2009 ).

A bilingual study of aphasia is important as it is necessary to be able to recommend treatment that satisfies a reasonable estimate of the recovery process. However, we lack the causal relationship of the recovery model. We distinguish neural representation of language network from the area related to network control. Contrary to some arguments, we demonstrate that a single adaptive network is the foundation of multilingual representation based on normal data and identify positive (top lobe) cortical networks in its control. As far as patient data is concerned, recovery of L1 and L2 is widely expected to be parallel with the level before disease if there is no language control problem. Recent advances mean that this prediction can be tested against patient specimens, not through sampled cases reported in the literature. Voxel based morphometry can be used to correlate changes in gray matter density and changes in mission performance

There are several commonly used tests and procedures for diagnosing patients with Broca aphasia. Western Aphasia Battery (WAB) classifies individuals based on scores in speech, hearing understanding, repeat, and naming subtests. Boston Diagnosis Aphasia check (BDAE) informs users of what type of aphasia is present, estimates the location of the lesion, and evaluates the current language ability. The corresponding pouch index (PICA) predicts the outcome of potential rehabilitation for aphasic patients. Measurement of quality of life is also an important evaluation tool. Through tests such as Aphasia People's Life Assessment (ALA) and Life Satisfaction Index Scale (SWLS), therapists can aim at important and meaningful skills for individuals.
