Unveiling the Sleepwalker’s World: A Closer Look at Parasomnias



Ever experienced a night so bizarre that you question your own nocturnal escapades? Dive into the intriguing world of parasomnias, where sleep turns into a surreal adventure.

What Is Parasomnia?

Parasomnias, a group of sleep disorders primarily occurring during non-REM (rapid eye movement) sleep stages, affect a small fraction of the population. These disorders encompass various unusual behaviors, often accompanied by partial amnesia upon awakening. Non-REM parasomnias include night terrors, sleepwalking, and sleep-related eating disorders.

Dr. Rafael Pelayo, a sleep medicine professor at Stanford University, recounts cases where individuals engaged in complex activities while asleep, such as having sex, rearranging furniture, or even operating heavy machinery. In extreme instances, parasomnias can lead to violent behavior towards others.

Research suggests that myths about supernatural beings, like werewolves, may have roots in parasomnias. People who unknowingly rearranged furniture or engaged in unusual behaviors while sleepwalking may have attributed these incidents to ghosts or supernatural forces.

These disorders stem from incomplete arousal from deep sleep, during which the body remains active while the mind is mostly dormant.

Factors like sleep deprivation, sleep apnea, antidepressant use, noisy environments, and irregular sleep schedules can contribute to fragmented sleep, increasing the likelihood of parasomnias. Genetics may also play a role, with children being more susceptible than adults.

Treatment for parasomnias prioritizes safety. Measures include sleeping separately from a bed partner if there is a risk of physical harm, using locks or barriers on doors (while ensuring emergency exits remain accessible), and employing bells to alert caregivers if a sleepwalker leaves the room.

Protective features on sharp objects and furniture can prevent injuries during sleepwalking episodes.

Medical evaluation is essential to identify medications that may trigger parasomnias. Sleep studies can detect conditions like sleep apnea, a potential contributor to these disorders.

Medications such as melatonin and clonazepam, along with benzodiazepines and specific blood pressure drugs, may be prescribed by doctors to manage symptoms.

Lifestyle adjustments are equally crucial. Maintaining a regular sleep schedule, optimizing sleep quality, managing stress, and creating a sleep-conducive environment are essential steps. Dr. Pelayo advises limiting alcohol consumption before bedtime, as it can exacerbate parasomnia symptoms.

In summary, parasomnias, characterized by unusual behaviors during non-REM sleep stages, affect a minority of individuals. Safety precautions, medication evaluations, and lifestyle modifications are key components of managing these disorders, which can disrupt sleep and pose safety risks.

Exercise Cuts Heart Disease Risk by Lowering Stress, Study Finds

New research indicates that physical activity lowers the risk of cardiovascular disease, in part by reducing stress-related signaling in the brain. The study, led by investigators at Massachusetts General Hospital and published in the Journal of the American College of Cardiology, found that people with stress-related conditions such as depression experienced the most cardiovascular benefits from physical activity.

To assess the mechanisms underlying the psychological and cardiovascular disease benefits of physical activity, Ahmed Tawakol, an investigator and cardiologist in the Cardiovascular Imaging Research Center at Massachusetts General Hospital, and his colleagues analyzed medical records and other information of 50,359 participants from the Mass General Brigham Biobank who completed a physical activity survey.
