Striatonigral Degeneration

Striatonigral degeneration is an atypical parkinsonian disorder (a phenotype of multiple system atrophy, MSA-P), characterized by severe, levodopa-unresponsive parkinsonism (rigidity/bradykinesia), often with autonomic failure (orthostatic hypotension/urinary incontinence) and cerebellar signs. Onset in late adulthood. There is no disease-modifying therapy; treatment is supportive, with management of autonomic symptoms and rehab; levodopa response is poor.

Common Symptoms

Severe levodopa-unresponsive parkinsonism; autonomic failure (orthostatic hypotension/urinary); cerebellar ataxia; late-adult onset

Causes and Pathogenesis

Alpha-synuclein glial cytoplasmic inclusions degenerate striatum/substantia nigra/autonomic/cerebellar structures (MSA-P).

Treatment

Supportive; manage orthostatic hypotension/urinary; rehab; levodopa trial (poor response)

Preventive Measures

Supportive care; manage autonomic symptoms; fall prevention.
