Smart system for diagnosing dizzy spells when standing
Part of Brain & nervous system, Heart & circulation clinical trials.
This study is testing a smart computer system that helps doctors diagnose orthostatic hypotension (a sudden drop in blood pressure when standing) more accurately. If you have Parkinson's, MSA, or diabetes and feel dizzy when standing, this might help you get a clearer diagnosis.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have been diagnosed with Parkinson's disease, multiple system atrophy (MSA), or diabetes (if diabetic, you must be at least 50 years old).
- You have symptoms of orthostatic hypotension (blood pressure drops when standing) or have been told you have it.
- You are able to have a special ultrasound of the brain (called TCD) done — this requires good 'acoustic windows' in your skull.
- You do not have severe narrowing of the arteries in your brain or neck, a recent stroke, or serious heart rhythm problems.

This study looks at how blood pressure is controlled in people with Parkinson's disease, especially those who feel dizzy when standing up. It may help doctors understand and treat this problem better.
This study measures how your blood pressure affects thinking skills and how blood flows in the brain in people with Parkinson’s. It may help researchers understand what blood-pressure changes could mean for cognition in Parkinson’s.
This study checks how your body controls breathing and heart rate when you stand up, especially if you get dizzy from low blood pressure. It may help researchers understand what causes symptoms and how to improve testing for people with this condition.
This early (Phase 1) study tests whether midodrine and droxidopa can improve blood-flow pooling in the belly in people with nerve problems that affect blood pressure when standing. It’s looking at safety and how the body responds, which may help reduce dizziness or fainting for some participants.
This study tests a new way to detect and warn about fainting in people with certain types of syncope (temporary loss of consciousness). It may help those who have already had a specific fainting evaluation called an ARS assessment.
This Phase 2 study tests whether the medicines droxidopa and pyridostigmine can improve symptoms of orthostatic hypotension, which is low blood pressure when you stand up. It is designed for people whose low blood pressure is caused by problems with the nerves that control blood pressure.
