Shy-Drager syndrome, with symptoms that include orthostatic
hypotension, impotence, abnormal sweating, increased salivation, and
pupil abnormalities, is classified as a Lewy body disease because in this disorder
Lewy bodies can be found within
a. α motorneurons in the spinal cord
b. Neurons in the cerebral cortex
c. Neurons in the dorsal vagal nuclei
d. Neurons in the nigrostriatal system
e. Sympathetic neurons in the spinal cord

because it seems like the Sympathetic NS is overstimulated....

The histologic presence of
Lewy bodies can be seen in several disorders (Lewy body disorders) that differ
in the location where the Lewy bodies are found.
In classic Parkinson’s disease, Lewy bodies are found in the nigrostriatal system (producing
extrapyramidal movement disorder).
In Lewy body dementia, Lewy bodies are found in the cerebral cortex (producing dementia; this is the third most common cause of dementia).
In Shy-Drager syndrome, Lewy bodies are
found in sympathetic neurons in the spinal cord (causing autonomic dysfunction,
including orthostatic hypotension, impotence, abnormal sweat and
salivary gland secretion, and pupillary abnormalities). In Lewy body dysphagia,
Lewy bodies are found in the dorsal vagal nuclei (producing dysphagia).
