Among older adults in a Tasmanian community cohort, 7.1% screened positive for probable REM sleep behavior disorder (pRBD). Females with pRBD reported more nightmares related to waking-life experiences than males. Compared to controls, the pRBD group recalled dreams more often, experienced more lucid dreams, and had more nightmares during childhood. The findings suggest that screening questionnaires focusing on aggressive dream features may miss females with RBD, and including questions about waking-life-related nightmares could improve detection.
A pilot randomized controlled trial compared a mindfulness-based intervention for tics (MBIT) with psychoeducation, relaxation, and supportive therapy (PRST) in 28 adults with Tourette's syndrome or persistent tic disorder. MBIT led to a significantly greater reduction in obsessive-compulsive symptoms at posttreatment than PRST. No significant differences between groups were found for ADHD symptoms, depression, anxiety, stress, or functional impairment at posttreatment. Outcomes at 1- and 6-month follow-ups were reported descriptively. The authors suggest larger clinical trials are needed to test these initial findings.
