Rare sleep disorder common among veterans with PTSD

21% of veterans who experience PTSD or traumatic brain injury suffer from a rare sleep condition that affects less than 1% of the general population. The condition, REM sleep behavior disorder (RBD), is characterized by an impairment of sleep-related muscle paralysis, causing people to act out dreams during REM sleep. The uncontrolled actions often cause harm to the sufferer of their partners.

The brain may actively forget during dream sleep

REM sleep has previously been linked to memory formation. A new study reveals this sleep period may also be critical for us to forget certain memories, preventing information overload. Researchers identified a mechanism involving MCH neurons which causes us to forget information during sleep.

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.

One in 10 people have ‘near-death’ experiences

Near-death experiences (NDEs) including hallucinations, out-of-body sensations and time distortions, affect around 10% of people, a new study reports. 72% of people overall who experienced NDEs say their experience was unpleasant. Researchers found an association between NDEs and REM sleep intrusion into wakefulness, resulting in sleep paralysis and hallucinations.

Stress and Dream Sleep Linked to Pathways of Neuron Death and Survival

According to a new study, the consequence of daily stress is linked to an increase in REM sleep. Researchers report the increase is associated with genes involved in apoptosis and cell survival. The findings shed light on how stress leads to mood disorders, and how changes in sleep contribute to this.
