Abstract

OBJETIVO: Investigar la hipótesis según la cual, el cerebelo podría participar en las alteraciones de la cognición social (CS). MÉTODO: Se administraron tests neuropsicológicos generales, de función ejecutiva (FE), de CS que evaluaban la capacidad de inferir el estado mental de otras personas y la escala de Depresión de Beck a 10 pacientes adultos con enfermedad cerebelosa adquirida aislada (GEC) y a 10 controles (GCO) apareados por edad, sexo y educación. Se analizaron los datos mediante ANOVA y correlación. RESULTADOS: El GEC obtuvo puntajes significativamente menores (p?0,05) que el grupo GCO en tareas de FE (Test de Wisconsin) y preguntas de creencia (PCr) de Teoría de la Mente (ToM). El rendimiento en las preguntas de control (PCo) de ToM fue similar en ambos grupos. El menor rendimiento en las PCr correlacionó significativamente con una menor habilidad conceptual, la severidad de la apatía (NPI) y de la ataxia estática. Las PCo correlacionaron con medidas de atención y de recuerdo diferido libre. CONCLUSÍON: El cerebelo contribuiría en el monitoreo de la conducta mediante el control de datos multimodales motores, cognitivos y emocionales.AIM: To investigate whether the cerebellum could participate in social cognition (SC). METHOD: General neuropsychological tests, executive tests (EF), social cognition tests, which assess the ability to infer other peoples’ mental states, and the Beck Depression Inventory were given to 10 non-demented patients with isolated cerebellar degenerative disease, and to 10 healthy controls matched for sex, age, and years of education. ANOVA and correlation coefficients were employed for the statistical analysis. RESULTS: Patients within the cerebellar group were significantly impaired (p?0.05) in EF test [Wisconsin Card Sorting Test (WSCT)] and belief questions (BQ) from Theory of Mind (ToM) tests. Performance in control questions (CQ) from ToM tests was similar for both groups. Lower scores in BQ correlated with a lower conceptual ability, the severity of apathy (NPI) and static ataxia. CQ correlated with measures of attention and free recall. CONCLUSION: The cerebellum may contribute in the control of social behavior through the processing of multimodal data, motor, cognitive and emotional.

Abstract

To compare executive functions (EF) in non-demented mild to moderate Parkinson's disease (PD) (Hoehn and Yahror =3) and pure degenerative cerebellar disease (CD) in order to evaluate the relative contribution and differential role of basal ganglia and cerebellum in those functions.14 patients with PD and 14 patients with CD matched by sex, education, disease's duration and MMSE were selected. A standardized neuropsychological battery and the Wisconsin Card Sorting Test (WCST) were administered. Z scores were compared for both groups through t-test for independent samples were used.The cerebellar group showed significant lower performance in measures of attention and EF, with a significant increase in both perseverative and non perseverative errors during the WCST. On the other hand the PD group showed a selective increase of non perseverative errors, without reaching significant between group difference.The CD group appears to have greater deficits in EF with a pattern of prefrontal dysfunction.

ANOVA and correlation coefficients were employed for the statistical analysis.Patients within the cerebellar group were significantly impaired (por=0.05) in EF test [Wisconsin Card Sorting Test (WSCT)] and belief questions (BQ) from Theory of Mind (ToM) tests.
