ABSTRACT

La disfunción cognitiva en la Enfermedad de Parkinson (EP) ha sido sólidamente estudiada; sin embargo, es escaso el conocimiento que se tiene sobre el deterioro cognitivo entre los pacientes con EP sin demencia y su relación con las variables clínicas, la sintomatología neuropsiquiátrica y la capacidad funcional. Consecuentemente, fueron evaluados 52 pacientes con EP sin demencia, 22 de los cuales fueron diagnosticados de deterioro cognitivo leve (DCL), emparejados con 52 personas neurológicamente sanas. Nuestros resultados confirman la existencia de una disfunción en la velocidad de procesamiento de la información, el funcionamiento ejecutivo, la memoria verbal y el procesamiento visoperceptual. Por otro lado, el DCL se asoció con una edad avanzada en el comienzo de la EP, mayor sintomatología neuropsiquiátrica, mayor estrés entre los familiares y mayor tendencia hacia la afectación de la capacidad funcional. El estudio apoya la hipótesis de que disfunciones específicas a nivel neuropsicológico, como la ralentización en el procesamiento de la información, pueden actuar como moduladores del deterioro funcional en la EP (AU)


Cognitive dysfunction in Parkinson’s Disease (PD) has been consistently reported, but little is known about cognitive impairment in PD patients without dementia, and its association with clinical characteristics, neuropsychiatric disturbance and functional activities. Therefore, we evaluated 52 non-demented PD patients, 22 of them with mild cognitive impairment (PD-MCI) who were matched with 52 healthy controls. Our results confirm the existence of dysfunction in information processing speed, executive function, verbal memory and visuo-perceptual processing in PD. On the other hand, PD-MCI was associated with advanced age at the onset of PD, more neuropsychiatric symptoms (AU)

ABSTRACT

Cognitive dysfunction in Parkinson's Disease (PD) has been consistently reported, but little is known about cognitive impairment in PD patients without dementia, and its association with clinical characteristics, neuropsychiatric disturbance and functional activities. Therefore, we evaluated 52 non-demented PD patients, 22 of them with mild cognitive impairment (PD-MCI) who were matched with 52 healthy controls. Our results confirm the existence of dysfunction in information processing speed, executive function, verbal memory and visuo-perceptual processing in PD. On the other hand, PD-MCI was associated with advanced age at the onset of PD, more neuropsychiatric symptoms, caregiver stress and functional problems. The study supports the hypothesis that specific neuropsychological impairments may act as modulators of functional impairment in PD, for instance slowness of information processing.
