RESUMO
The impact of excessive daytime sleepiness (EDS) on road test performance was examined in patients with Parkinson's disease (PD). Twenty-one patients with PD completed the Epworth Sleepiness Scale (ESS) and an on-road driving test. Five participants had EDS according to their self-report on the ESS. Neither EDS nor PD medications were associated with on-road driving performance. These findings suggest that in this pilot study EDS did not impair PD patients' driving skills on a formal driving evaluation.

Leucoencephalopathy with neuroaxonal spheroids (LENAS) is a rare disease of cerebral and cerebellar white matter. LENAS usually presents as a disorder of cognition and behaviour, or with gait dysfunction and ataxia. This report describes a patient who had a 14 year course of progressive neurological decline consistent with a clinical diagnosis of probable multiple system atrophy, with prominent cerebellar dysfunction and dysautonomia. Formal autonomic laboratory testing was consistent with global autonomic dysfunction of central origin. However, magnetic resonance imaging showed extensive white matter signal abnormalities, in addition to moderate cerebral and cerebellar atrophy. On postmortem microscopic examination, there were numerous axonal spheroids throughout the white matter of both regions. This case of LENAS presented unique clinical characteristics, and typical pathological findings.
