Patients with chronic neurodegenerative disorders such as Parkinson's disease (PD), multiple system atrophy (MSA), or pure autonomic failure (PAF) are at risk of neurogenic orthostatic hypotension (nOH).1,2 These neurodegenerative disorders may adversely affect a patient's autonomic nervous system, resulting in the release of inadequate amounts of norepinephrine in response to postural changes.2-9 If postural changes cause symptoms of nOH such as dizziness or lightheadedness, the risk of falling may be increased.6,8,10 Patients whose symptoms improve upon sitting may have nOH.3,8 Supine hypertension is often associated with patients who experience symptoms of nOH.4,11-13

~1 in 5 patients with PD experience nOH symptoms1

  • Prevalence varies in relation to the fluctuating levels of orthostatic stress a patient may be experiencing6,14        
  • Some patients may dismiss nOH symptoms as a part of their Parkinson's disease6

~4 in 5 patients with MSA experience nOH symptoms1

  • Also known as Shy-Drager syndrome, MSA is an adult-onset, progressive neurodegenerative disorder characterized by parkinsonian features, cerebellar ataxia, and autonomic failure3,12,15,16
  • nOH is considered a hallmark sign of MSA15,16

Nearly all patients with PAF experience nOH symptoms1

  • Also known as Bradbury-Eggleston syndrome, PAF is a disorder that is characterized by the degeneration of the autonomic nervous system5,17
  • Slightly more prevalent in men than women and affects middle-aged adults18

“I thought my symptoms were from the Parkinson's. I was falling a lot, I was dizzy. I had a heavy feeling in my shoulders and neck. My vision was blurred…I later realized that those were nOH symptoms.” –Jody, patient with symptomatic nOH
