Circadian Rhythm Disorder

circadian rhythm disorder and difficulty sleeping

Chronic circadian rhythm sleep disorders are internal abnormalities of the circadian rhythms, the body’s internal clock. They arise when a person is unable to fall asleep at a normal bedtime (late evening), although he/she is able to sleep at other times.  The length of the internal circadian cycle can normally be a bit shorter or longer than 24 hours.  The cycle is entrained to 24 hours by external factors, especially light.  If it cannot be entrained, either because it is too far afield of the normal range, or for other neurological reasons, the result is a circadian disorder.  In these disorders, the internal coordination of the various rhythms may also be normal or faulty.  For example, some hormones may be on a different cycle than others.

Common to these disorders is inflexibility: even when physically tired or sleep deprived, sufferers cannot make up for lost sleep outside of their hard-wired sleep times.  This factor is generally misunderstood by people who do not suffer from these disorders, leading to misunderstanding of what sufferers are up against, and a conclusion that they are just lazy or haven’t tried hard enough to live on a normal schedule. 

The International Classification of Diseases (ICD-10-CM, 2014) lists 6 subtypes of circadian rhythm sleep disorder:

  • Delayed sleep phase type.
  • Free-running type.
  • Advanced sleep phase type.
  • Irregular sleep-wake type.
  • Shift work type.
  • Jet lag type.
  • As well as unspecified, other, and conditions specified elsewhere.

The DSM-V defines Circadian Rhythm Sleep-Wake Disorder as follows:

A persistent or recurrent pattern of sleep disruption that is primarily due to an alteration of the circadian system or to a misalignment between the endogenous circadian rhythm and the sleep-wake schedule required by an individual’s physical environment or social or professional schedule.  The sleep disruption leads to excessive sleepiness or insomnia, or both.   The sleep disturbance causes clinically significant distress or impairment in social, occupational, and other important areas of functioning.

    Went in for a consult at the lancaster office almost 2 years ago where the staff took my vitals and then took some baseline readings which lasted 20-30 mins. Turns out that those baseline readings test cost more than the actual overnight sleep study that i ended up taking a couple weeks later, but didn't learn about this fact until i went back in on the 3rd visit for my sleep study results. Was told that i had obstructive sleep apnea and would definitely need to come back in for an additional sleep study to be fitted for a CPAP, but 1st needed to get some financials squared away. That was perfectly fine until i saw a charge for my consultation that cost more than the sleep study. For 20-30 mins and that justifies a $1400 charge, insane! My insurance covered half of this fiasco whereas i only paid copays for each visit, and didn't pay another cent to them beyond that. Seems rather shady to slip some high priced diagnostic test in during the consultation. I would have payed my half of the sleep study, but nothing for the other test. So here i am, roughly 2 years later still with obstructive sleep apnea, still no CPAP, and getting worse. Buyer beware, go elsewhere.

    Poor service. If I could give zero stars I would. They don't return phone calls. If you need prescriptions or paperwork completed to obtain your medical equipment, they won't submit correctly, and then will get an attitude with you. They are rude and medically incapable of doing right for the patients.

    Can I give no stars? So slow and long wait to get in. Even when there is no one in the waiting room. And they want to have me come in every time I need a new prescription for a controlled substance. This is not due to Ohio laws this is just their policy. I’m sorry but who with a full time job can call off work once a month just to get a refill??? My advice is go to your family doctor to have them refill your prescription every 3 months instead. Don’t go here. I’ve been out of medications due to the fact they don’t answer their phone or they don’t send out the prescription promptly. They informed me last minute I wouldn’t be able to get my prescription because I haven’t seen them in a year. Like wow now I have no medication. Great.
