LINGUISTIC DISORDER IN PARKINSON S DISEASE. STATISTICAL APPROACH TO A STUDY WITH VARIANTS

Abstract

There are not many studies on linguistic disturbances of Parkinson patients and a few we can find do not offer a complete picture about how all the language components are affected (phonetic-phonologic, grammatical, lexical, semantic, pragmatic and textual level), which are located in different brain areas. Our main aim has to do with the relationship between language alterations and several clinical facts, as well as sociodemographic aspects within a group of patients who are affected by Parkinson. We have selected 46 patients, 42 of them have different kind of language disturbances, which have been related with socio-demographic (age, sex and cultural level) and clinical variables (progression time of the disease, Hoeh & Yahr Scale, UPDRS-III, and L-dopa treatment). According to the distributions of previous variables, Test T of Student or U of Mann Withney has been used.
