Acting Out Dreams: Sleep Disorder A Warning Sign of Parkinson’s Disease

Researchers are probing into REM sleep behavior disorder (RBD), a condition where people physically act out their dreams. This parasomnia is more than a nocturnal hazard: research indicates a strong link between RBD and neurodegenerative diseases like Parkinson’s.

To make this discovery, scientists first used transgenic fat-1 mice, which express high endogenous omega-3 polyunsaturated fatty acids (PUFAs) in the brain, to investigate the effect of omega-3 PUFAs on the clearance function of the glymphatic system.

Adults Sleep Better Together Than They Do Alone

Adults who share a bed with their partners sleep better than those who sleep alone. Researchers found bed-sharing was associated with a lower risk of depression and stress, and improved quality of life and relationships. However, sharing a bed with a child was associated with more stress.

After 10-year search, scientists find second ‘short sleep’ gene

Researchers have identified a second gene that contributes to natural short sleep. Using optogenetics, researchers triggered neurons in the pons that express the ADRB1 gene, rousing mice from sleep. Wakefulness-promoting neurons in the pons with a mutated version of ADRB1 were more easily activated.
