Psychogenic inversion of circadian rhythm, also known as psychogenic delayed sleep phase disorder (DSPD), refers to a sleep disorder characterized by a significant delay in a person's sleep-wake cycle, resulting in a misalignment with the typical 24-hour day-night cycle. This condition is primarily attributed to psychological or psychiatric factors rather than underlying biological abnormalities.
Individuals with psychogenic inversion of circadian rhythm experience difficulty falling asleep at conventional times, leading to a delayed sleep onset and consequently a delayed awakening time. This pattern persists despite attempts to adjust their sleep schedule, causing them to have difficulty meeting social and occupational commitments that require them to be awake during conventional hours.
Unlike other forms of circadian rhythm sleep-wake disorders, the psychogenic variant is not caused by any underlying neurological or medical conditions. It is believed to be primarily influenced by psychological factors such as stress, anxiety, depression, or other mental health issues. These factors can disrupt the person's natural sleep-wake cycle and lead to a delayed pattern.
Treatment for psychogenic inversion of circadian rhythm typically involves a comprehensive approach that integrates psychological interventions, such as cognitive-behavioral therapy (CBT), with lifestyle adjustments. CBT can help individuals modify their behaviors and thoughts related to sleep, establish a consistent sleep routine, and instill healthier sleep habits. Additionally, light therapy and chronotherapy may be recommended to help gradually shift the person's sleep-wake schedule towards a more socially acceptable pattern.
It is important to note that a proper diagnosis should be made by a qualified medical professional or sleep specialist to differentiate psychogenic inversion of circadian rhythm from other sleep disorders or medical conditions that may cause similar symptoms.
