Sleep inversion may be a symptom of elevated blood ammonia levels [2] and is often an early symptom of hepatic encephalopathy. [3] Sleep inversion is a feature of African trypanosomiasis, after which the disease takes its common name, "African sleeping sickness"; [4] sleep-wake cycle disturbances are the most common indication that the disease has reached the stage where infection spreads into ...
Chronic sleep deprivation (less than 8 hours of sleep) is associated with an increase in body mass index (BMI) and obesity. In a study with 3000 patients, it was found that men and women who sleep less than 5 hours have elevated body mass index (BMI). In another study that followed about 70.000 women for 16 years, there was a significant ...
The diagnosis of a bipolar disorder is linked to various sleep disorders. [15] Comorbidities include insomnia and hypersomnia. [16] Other related sleep disturbances are delayed sleep phase syndrome, circadian-rhythm sleep disorder, sleep apnea, REM sleep abnormalities and irregular sleep-wake schedules.
A new study offers an explanation as to how deep sleep — also known as slow wave sleep — helps support the formation of memories in the brain, which could help with preventing dementia.
Studies on rodents show that the response to neuronal injury due to acute sleep deprivation is adaptative before three hours of sleep loss per night and becomes maladaptative, and apoptosis occurs after. [35] Studies in mice show neuronal death (in the hippocampus, locus coeruleus, and medial PFC) occurs after two days of REM sleep deprivation.

Circadian rhythm sleep disorders (CRSD), also known as circadian rhythm sleep–wake disorders (CRSWD), are a family of sleep disorders that affect the timing of sleep. CRSDs cause a persistent pattern of sleep/wake disturbances that arise either by dysfunction in one's biological clock system, or by misalignment between one's endogenous oscillator and externally imposed cues.
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
