✦ Synopsis

Abstract

We investigated the acoustic startle response in eight patients with MSA and compared the results with those from a group of age matched healthy subjects. Onset latency and amplitude of the responses obtained in the orbicularis oculi, masseter and sternocleidomastoid muscles were not different in patients and control subjects. We conclude that, in spite of the pathological derangement described in brainstem reticular nuclei in MSA, the neuronal circuits mediating the auditory startle reflex are functionally preserved.

## Abstract Multiple system atrophy (MSA) is characterized clinically by Parkinsonism, cerebellar dysfunction, and autonomic impairment. Multiple mutations in the __LRRK2__ gene are associated with parkinsonian disorders, and the most common one, the G2019S mutation, has been found in ∼1% of sporad
