What Is the Circadian Rhythm?
8. Diagnosis and Treatment
Although mainly a clinical diagnosis, it is important to assess the risk of accidents and exclude medical conditions such as obstructive sleep apnea. Imaging studies can be beneficial in the evaluation of neurodegenerative disease. Another beneficial test would be actigraphy, a small motion-sensing device that grossly measures the sleep-wake cycles. Sleep tests such as the multiple sleep latency test and the Epworth sleepiness scale can also be performed.
Some of the therapies that may be recommended include bright light therapy, chronotherapy, enhancement of environmental cues, and medication (Tasimelteon, benzodiazepines, melatonin). Consultations with a sleep medicine specialist, psychiatrist, pulmonologist, or neurologist may also be beneficial. Good sleep hygiene should be encouraged.
