Norepinephrine Transporter Blockade as a Pathological Biomarker in Neurogenic Orthostatic Hypotension (6103)
Pure Autonomic Failure
Multiple System Atrophy
|Study Design:||Time Perspective: Prospective|
|Official Title:||Norepinephrine Transporter Blockade as a Pathophysiological Biomarker in Neurogenic Orthostatic Hypotension|
- Final Diagnosis (pre vs post ganglionic autonomic failure) based on clinical criteria. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
Probable MSA - PAF with urinary incontinence or an orthostatic decrease of 30 mmHG in systolic blood pressure within 3 minutes of standing and poorly levodopa responsive parkinsonism or a cerebellar syndome.
For Possible MSA - parkinsonism or a cerebellar syndrome and one additional feature.
Probable PAF - orthostatic hypotension and impaired autonomic reflexes in the absence of clinical signs or symptoms of neurodegeneration.
For Parkinson's Disease: diagnosed based on the United Kingdom Parkinson Disease Society Brain Bank clinical diagnostic criteria.
