Recent studies show that mental illness significantly increases the risk of dementia and other cognitive deficits. Insomnia in older persons increases their risk of memory loss and long-term cognitive impairment, including dementia, according to recent Canadian research. Over 26,000 participants in the Canadian Longitudinal Study on Aging, ranging in age from 45 to 85, provided data for the study, which was published in the journal SLEEP. The researchers contrasted neuropsychological testing in various cognitive areas from 2019 and a follow-up in 2022 with completed self-reported sleep and memory assessments. Those who claimed their sleep had gotten poorer over the course of those three years were more likely to report subjective memory decline. "Adequately managing insomnia condition might become an important preventive tool for cognitive deterioration," write Jean-Louis Zhao and Nathan Cross.

Sleep-related brain activity patterns can be utilized as a biomarker to identify the start of neuropsychiatric illnesses in patients with 22q11.2 Deletion Syndrome (22q11.2DS), a genetic abnormality that sheds information on the neurobiology underlying the condition. 1 in 3000 births result in 22q11.2DS, which is brought on by a gene loss of about 30 genes on chromosome 22. It raises the chance of epileptic seizures, autism spectrum disorder (ASD), intellectual disability, and attention-deficit hyperactivity disorder (ADHD). Additionally, it ranks highly among the biological risk factors for schizophrenia. Uncertainty surrounds the molecular processes that underlie the psychological symptoms of 22q11.2DS, though. According to co-senior author Marianne van den Bree, Professor of Psychological Medicine at Cardiff University, UK, "We have recently shown that the majority of young people with 22q11.2DS have sleep problems, particularly insomnia and sleep fragmentation, that are linked...
