Multiple completed clinical trials, encompassing Phase 4 and unassigned phase studies, have evaluated cognitive performance during sleep deprivation as well as therapeutic strategies for psychiatric conditions including schizophrenia, schizoaffective disorder, and psychotic disorders. Sponsored by medical and academic institutions such as Herlev Hospital, the TRYG Foundation, the Danish Medical Association, and the Central Institute of Mental Health Mannheim, these investigations focused on sleep loss and psychiatric health.
