## Abstract Although urinary disturbances are more frequent in multiple system atrophy (MSA) than in Parkinson's disease (PD), the striatonigral degeneration (SND) type of MSA is difficult to distinguish from PD, especially when the latter is associated with orthostatic hypotension or urinary sympt

✦ Synopsis
Striatonigral degeneration (SND) is difficult to diagnose in vivo. The purpose of this study was to detect the best indicators for an early and reliable diagnosis of the disease. Eighteen patients clinically diagnosed as having SND were selected with rigorous inclusion criteria and compared to 18 patients with Parkinson's disease (PD) matched for age and disease duration. Apart from dysautonomia, the principal discriminant clinical features that distinguished SND from PD were the early appearance of the following symptoms and signs: (a) severe and atypical progressive parkinsonism characterized by bilateral bradykinesia and rigidity, slowness of gait, postural instability, and falls, and poor or absent response to adequate levodopa treatment; (b) increased tendon reflexes associated or not with frank pyramidal signs, severe dysarthria, and less consistently, dysphagia, stridor, antecollis, and stimulussensitive myoclonus, which, when present, are highly suggestive of the disease.

## Abstract The objective of this study is to compare physical performance measures for their ability to discriminate between levels of disability and disease severity in Parkinson's disease (PD). Disability in PD is commonly assessed by patient self‐report, which may be limited by patient insight.

## Abstract Few prospective data on the clinical progression of Parkinson's disease (PD) in patient groups outside treatment trials in selected patients are available, and controversy exists on the rate of clinical disease progression with advancing disease. In this study, we investigated the rate
