Cortical & Subcortical Dementias: A Psychoneurolinguistic Perspective

Abstract

Background: A rapidly increasing number of studies that focus on the relationship between language and cortical (CD) and subcortical dementias (SCD) have recently shown that such correlation is existent. Mounting evidence suggests that cognitive impairments should be investigated against language disorders.

Aims: This study aims at investigating how language is associated with dementia diseases namely CD &SCD in light of psychoneurolinguistic approach.

Method: Data from multiple sources (e.g., theses, dissertations, articles, researches, medical records, direct testing, staff reports, and client observations) have been integrated to provide a detailed analysis of the relationship between language and CD & SCD. The researchers identified over 20 most of dementia types, and described them. Having the collected and described data, the researchers then analyzed these data independently to see to what extent CD & SCD are involved in matters concerning language.

Results: Results of the present study demonstrate that language and CD & SCD are undoubtedly correlated with each other. The loss of the ability of some organs to perform certain functions (due to any of the dementia disease) results in no way to the loss of some language aspects and /or speech skills. In clearer term, it is rare to find a patient with dementia who is not suffering from partial or complete linguistic difficulties. Many deficits run through current interpretation of linguistic disorders: language disorders, speech disorders, articulation disorders, or voice disorders.
