Shay-Dregue syndrome

Shay-Drager Syndrome (SDS), also known as progressive autonomic failure, idiopathic orthostatic hypotension, neurogenic orthostatic hypotension, are Shy and Drager Autopsy cases were first reported in 1960, suggesting that the disease is a neurological degenerative disease. This disease is a rare disease with extensive degeneration of the central nervous system, including the autonomic nervous system. The patients are sporadic. In addition to orthostatic hypotension, clinical manifestations include sweating disorders, impotence and other autonomic dysfunctions. Cone system, extrapyramid system, cerebellar ataxia and other somatic neurological symptoms are characterized. Some people believe that OPCA is associated with autonomic neurological symptoms, such as orthostatic hypotension, dizziness or syncope, impotence, urinary incontinence, etc., and is considered to be Shay-Dregue syndrome. SDS is currently considered to be a type of multiple system atrophy (MSA).
