PURPOSE OF REVIEW This article reviews the -synucleinopathies pure autonomic failure, multiple system atrophy, dementia with Lewy bodies, and Parkinson disease with respect to autonomic failure. RECENT FINDINGS The pattern and severity of autonomic involvement in the synucleinopathies is related to differences in cellular deposition and neuronal populations affected by -synuclein aggregation, which influences the degree and manifestation of autonomic failure. Clinical and laboratory autonomic features distinguish the different synucleinopathies based on pattern and severity. These features also determine which patients are at risk for evolution from pure autonomic failure to the synucleinopathies with prominent motor involvement, such as multiple system atrophy, dementia with Lewy bodies, or Parkinson disease. SUMMARY Autonomic failure is a key feature of the synucleinopathies, with varying type and degree of dysfunction from predominantly peripheral involvement in the Lewy body disorders to central involvement in multiple system atrophy.
