Vivid dreams are a common complaint in Parkinson’s. But when those dreams come with movements—reaching into the air, kicking, punching, or accidentally striking your bed partner—we think about REM sleep behavior disorder, or RBD. I’ve met someone who swung his arm and fell off the bed.
REM stands for rapid eye movement, a stage of sleep when many vivid dreams happen. Normally, our brain keeps most of our muscles still while we dream. With RBD, that protective system doesn’t work properly.
Some people don’t connect this with Parkinson’s because they’ve been doing it for so long. But RBD can begin years—even decades—before movement symptoms appear. Having it doesn’t automatically mean someone has Parkinson’s.
Sleep apnea can look similar, and certain medications can bring on or worsen these behaviors, so it’s worth mentioning to your provider.
The first priority is keeping you and your bed partner safe. Clear sharp objects from beside the bed, pad nearby furniture, and consider sleeping separately if movements are forceful. Don’t wait for an injury before getting help.
When treatment is needed, I’ve used melatonin. Another option is clonazepam, a prescription medicine in the benzodiazepine family.
Melatonin can be an affordable, generally well-tolerated option. It helps signal nighttime to the brain and may reduce dream enactment, although we’re still learning exactly how it works for RBD. It can still cause side effects, including morning sleepiness.
Remember that quality matters. Supplements don’t go through the same FDA approval process as medications, and the amount inside may differ from what’s on the bottle. Look for independent, third-party testing.
If melatonin hasn’t helped, talk with your provider about the product, formulation, and dose. Some people need a dose adjustment based on their symptoms and health factors.
I’ve included a melatonin option on My Wellness Shelf if you’d like to explore it. Check with your provider about what’s right for you.
Sleep well—and safely!
