Procesamiento sintáctico en personas con enfermedad de Parkinson

Abstract

Background and objective

Parkinson's disease is a neurodegenerative pathology produced by the Nigrostriatal system damage. For many years the motor systems of this alteration were studied, however in the last decade the efforts have focused on the cognitive symptoms, particularly the language. The objective of this investigation was to describe the characteristics of the syntactic process in people with Parkinson's disease with measures of precision and time of response.

Patients and method

Twenty four Parkinson disease subject were assessed with a syntactic comprehension experimental paradigm. At the end of each sentence a dichotomous comprehensive question was made.

Results

Significant differences were observed in response accuracy among the different types of sentences evaluated. The subjects present a lower success rate in sentences of greater syntactic complexity and use more time in wrong answers and in sentences with gender syntax inconsistencies versus simpler grammatical structures.

Conclusion

Parkinson disease subject shown higher impairment in the comprehension of complex sentences.
