Medical News Today: How waste gets 'washed out' of our brains during sleep
A new study shows, for the first time, that cerebrospinal fluid washes into and out of the brain in waves during sleep, helping clear out waste.
Neuroimaging studies revealed that emotion and cognition dysfunction after sleep deprivation is associated with the disturbance of the salience network. However, the age effect on the functional connectivity changes of the network after sleep deprivation remains unclear. The current study investigated the functional connectivity changes of the right anterior insula after partial sleep deprivation in young and old adults by using resting-state functional magnetic resonance imaging. We found a significant age × deprivation interaction effect on the functional connectivity between the right ventral anterior insula and t...
CONCLUSION: Sleep disorders in neurology and psychiatry are a heterogeneous group of disorders with diverse manifestations. Their proper diagnosis and treatment can help prevent secondary diseases and the worsening of concomitant conditions. Care structures for the treatment of sleep disorders should be further developed.

(Reuters Health) - People who have trouble falling asleep or staying asleep may be more likely to have a heart attack or stroke than individuals who don't have any sleep difficulties, a recent study suggests.
The portable gadget targets the brain's hypothalamus region with electrical currents to promote a better night's sleep. It will be available to people in the UK next year.
Authors: Kang SG, Kim YK Abstract Cognitive behavioral therapy for insomnia (CBT-I) is the treatment of choice for insomnia; however, it is not widely used due to a lack of experienced therapists and its relatively high clinical cost. Recently, Internet and mobile CBT-I have been developed to replace face-to-face CBT-I, and research on this topic has been increasing. In addition, attempts have been made to use wearable devices for sleep-wake estimation. Studies on digital CBT-I thus far have shown favorable treatment effects in general, but the problem of a high dropout rate has not been sufficiently improved. In a...
In recent years, several GWAS (genome wide association studies) of sleep-related traits have identified a number of SNPs (single nucleotides polymorphism) but their relationships with symptoms of insomnia are ...

ConclusionsA history of MST is common among older women veterans and associated with a range of medical and mental health diagnoses. These findings call attention to the need for additional research in this understudied population, and the importance of trauma-informed care approaches for women across the lifespan.

ConclusionsInsomnia symptoms, which were commonly seen after the earthquake, could longitudinally predict the development of PTSD and various somatic symptoms, and PTSD and headache could longitudinally predict the developments of insomnia symptoms among children and adolescent earthquake survivors. These findings highlight the importance of assessing and addressing insomnia symptoms in children and adolescents following a traumatic event.
