Abstract

BACKGROUND
Cerebellum has an important role in sensorimotor control including speech. Multiple system atrophy (MSA) is a sporadic and rapidly progressive neurodegenerative disorder that presents with autonomic failure in combination with Parkinsonism or cerebellar ataxia.
CASE REPORT
We report a case of MSA-cerebellum subtype associated with emergence of irreversible explosive speech following olanzapine therapy.
CONCLUSIONS
Further investigation into speech problems in MSA according to subtype and disease severity is needed, and side effects of olanzapine therapy should also be considered.

Figure

  • Fig. 1 T2-weighted FLAIR MRI. (A) Severe atrophy of the pontocerebellar region with hot-cross bun sign (arrow). (B, C) Axial and coronal sections showing atrophic changes in the bilateral frontal area predominantly on the left side (open arrow). (D) Midline sagittal section showed prominent pontocerebellar atrophy. These atrophic changes were observed via voxel-based morphometry (false discovery rate, p<0.05). FLAIR: fluid attenuated inversion recovery, MRI: magnetic resonance imaging, RT: right side, LT: left side.
