Sleep Paralysis

Research Study on Familial Sleep Paralysis

Do you suffer from frequent episodes of sleep paralysis? Sleep paralysis occurs upon awakening or falling asleep. During these episodes, the patient is awake but is unable to move. These experiences are often scary and can also involve unusual feelings. For some patients, these episodes occur frequently and appear to run in families.

The Department of Neurology at the Johns Hopkins Hospital is conducting a research study to identify the genetic basis of familial sleep paralysis. The purpose of this study is to develop a better understanding of how the brain transitions from sleep to wake.

We are recruiting adult subjects (at least 18 years of age) who experience sleep paralysis on a frequent basis (at least once/year) AND have other family members (at least one first-degree relative) who also experience sleep paralysis frequently. Taking part of this research study would involve a medical history and a blood draw/saliva collection.

If you are interested in taking part in this research study, please send us an email at marknwu (AT) or ask your Johns Hopkins sleep physician.
