Bipolar disorder is difficult to treat, so light therapy was looked at as a potential solution. One relevant study was a meta-analysis of light therapy trials for bipolar disorder. The findings overall were encouraging as well as non-conclusive. The findings indicate that light therapy can limit symptoms and improve clinical response. [25]
A circadian rhythm is an entrainable, endogenous, biological activity that has a period of roughly twenty-four hours. This internal time-keeping mechanism is centralized in the suprachiasmatic nucleus (SCN) of humans, and allows for the internal physiological mechanisms underlying sleep and alertness to become synchronized to external environmental cues, like the light-dark cycle. [3]
The possible causes of non-24-hour sleep-wake disorder are 2-fold: (1), extrinsic: isolation from daily light cycles (such as working in an environment completely devoid of natural lighting); [citation needed] and (2), intrinsic: where some condition, such as blindness or malfunctioning biochemical response to light in the subject, prevent ...
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections.
The current formal name established in the third edition of the International Classification of Sleep Disorders (ICSD-3) is delayed sleep-wake phase disorder. Earlier, and still common, names include delayed sleep phase disorder (DSPD), delayed sleep phase syndrome (DSPS), delayed sleep phase type (DSPT), and circadian rhythm sleep disorder. [37]
This isn’t the first time that better sleep has been linked with a lower risk of dementia: A study published in October even found that people with sleep apnea are more likely to develop dementia.
Sleep specialists measure the patient's sleep onset and offset, dim light melatonin onset, and evaluate Horne-Ostberg morningness-eveningness questionnaire results. Sleep specialists may also conduct a polysomnography test to rule out other sleep disorders like narcolepsy. Age and family history of the patient is also taken into consideration. [2]
Irregular sleep-wake rhythm (ISWR) disorder is thought to be caused by structural damage to the SCN, decreased responsiveness of the circadian clock to light and other stimuli, and decreased exposure to light. [4] [42] People who tend to stay indoors and limit their exposure to light experience decreased nocturnal melatonin production. The ...
