Some people with the disorder are unable to adapt to earlier sleeping times, even after many years of treatment. Sleep researchers Dagan and Abadi have proposed that the existence of untreatable cases of DSPD be formally recognized as a "sleep-wake schedule disorder (SWSD) disability", an invisible disability.

The delay in sleep cycles clashes with the structured early morning schedules of students due to early classes or work; thus, the total amount of sleep time is greatly reduced. [17] This imbalance in circadian rhythm can lead to extremely harmful affects on students' learning and memory processes as well. [18]
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.
Sleep disturbances often occur before the onset of psychosis. Sleep deprivation can also produce hallucinations, delusions and depression. [26] A 2019 study investigated the three above-mentioned sleep disturbances in schizophrenia-spectrum (SCZ) and bipolar (BP) disorders in 617 SCZ individuals, 440 BP individuals, and 173 healthy controls (HC).
To improve your sleep at night, establish a consistent morning routine: Focus on waking up around the same time each day (including weekends and holidays), and try to expose yourself to circadian ...
Sleep deprivation also has a documented effect on the ability to acquire new memories for subsequent consolidation. A study done on mice that were sleep deprived before learning a new skill but allowed to rest afterward displayed a similar number of errors on later trials as the mice that were sleep deprived only after the initial learning. [46]
A sleep diary can be used track time to bed, total sleep time, time to sleep onset, number of awakenings, use of medications, time of awakening, and subjective feelings in the morning. [95] The sleep diary can be replaced or validated by the use of out-patient actigraphy for a week or more, using a non-invasive device that measures movement. [96]
