Video: Making Sense of Orthostatic Hypotension

A common symptom of Parkinson's disease, orthostatic hypotension is a sudden drop in blood pressure upon changing positions, such as moving from sitting to standing. This condition may cause lightheadedness and dizziness, which can result in passing out, fatigue and nausea. It could also contribute to gait instability and falls.

The National Organization for Rare Disorders produced this video to educate on the signs of neurogenic orthostatic hypotension (nOH) and available treatments. nOH is a subtype of orthostatic hypotension that occurs with neurological disorders. Orthostatic hypotension can also be caused by dehydration, heart problems and certain medications.

"I's like to see an awareness of nOH, and not only that it exists, but there are ways of dealing with it," says Jack Gernsheimer, who has Parkinson's, says in the video.
