Abstract

GATTO, Emilia et al. Cognition in a multiple system atrophy series of cases from Argentina. Arq. Neuro-Psiquiatr. [online]. 2014, vol.72, n.10, pp.773-776. ISSN 0004-282X.  http://dx.doi.org/10.1590/0004-282X20140127.

Cognitive dysfunction may occur in 17-40% of patients with multiple system atrophy (MSA). It has been suggested a milder cognitive impairment in cerebellar (MSA-C) than in parkinsonian variant (MSA-P). However, differences in cognitive profiles remain under discussion.

Objective

To evaluate cognitive features in a series of patients with “probable MSA” from Argentina.

Method

After informed consent was obtained, an extensive cognitive tests battery was administered. Nine patients (6 MSA-P and 3 MSA-C) composed the sample.

Results

Depression was detected in 43% of patients. Seven patients showed at least one cognitive domain impairment. Temporospatial orientation, visuospatial abilities, executive and attentional functions, episodic memory and language were compromised in MSA-P, while MSA-C dysfunction was restricted to attentional and executive domains.

Conclusion

Despite the small sample size, our findings could suggest a more widespread cognitive impairment in MSA-P than MSA-C.
