Thank you for your explanation of rhythmic sleep disorder and treatment possibilities. The persons severely affected by this disorder (and their loved ones) no doubt suffer greatly.
Sincerely.
Hi
There is a category of sleep disorders known as circadian rhythm sleep disorders (CRSDs) which are caused by a drug or substance or due to some medical conditions. The examples of a few drugs can be alcohol, pain killers, blood pressure /cholesterol/heart medications, sleeping pills, muscle relaxants, CNS medications, caffeine, etc. Some of the medical conditions leading to CRSDs can be dementia, Parkinson’s disease, sleep apnea, periodic limb movement disorder, etc.
The symptoms include disruption of the normal sleep-wake cycle circadian rhythm. The patients may get to sleep very late or very early or the sleep may be interrupted several times. In one pattern, sleep onset gets delayed everyday.
Treatment involves stopping the drug/substance involved, change of medications, and treatment of the underlying condition. I would advise that you consult a sleep specialist or a physician with your sleep diary for a complete medical evaluation. The treatment is directed towards rephasing the sleep cycle and circadian rhythm in accordance with the external environment.
Sleep therapy along with sleep hygiene (avoiding caffeine, alcohol and tobacco as well as stress reduction) in due course of time helps the patient get proper night sleep. The other treatment options available are bright light therapy and chronotherapy. Your doctor may advise you some Cognitive behavioral therapy (CBT) which might improve your sleep.
The different approaches used are stimulus control, sleep restriction, relaxation therapy, psychotherapy and maintaining sleep hygiene. You are taught not to read, watch TV, or do anything else in bed. You are also taught to go to bed only when you feel very sleepy.
Regards.
