“On which side of the bed did you get up this morning?” Obviously, your inquisitor assumes that to avoid clumsily crawling over your sleeping partner you always get up on the side with the table stacked with unread books.
You know as well as I do that you have just received a totally undisguised comment on your recent behavior that has been several shades less than cheery. You may have already sensed your own grumpiness. Do you have an explanation? Did the commute leave you with a case of unresolved road rage? Did you wake up feeling unrested? How often does that happen? Do you think you are getting enough sleep?
Dr. William G. Wilkoff
A few weeks ago I wrote a Letters From Maine column in which I shared a study suggesting that the regularity of an individual’s sleep pattern may, in many cases, be more important than his or her total number of hours slept. In that same column I wrote that sleep scientists don’t as yet have a good definition of sleep irregularity, nor can they give us any more than a broad range for the total number of hours a person needs to maintain wellness.
How do you determine whether you are getting enough sleep? Do you keep a chart of how many times you were asked which side of the bed you got up on in a week? Or is it how you feel in the morning? Is it when you instantly doze off any time you sit down in a quiet place?
Although many adults are clueless (or in denial) that they are sleep deprived, generally if you ask them and take a brief history they will tell you. On the other hand, determining when a child, particularly one who is preverbal, is sleep deprived is a bit more difficult. Asking the patient isn’t going to give you the answer. You must rely on parental observations. And, to some extent, this can be difficult because parents are, by definition, learning on the job. They may not realize the symptoms and behaviors they are seeing in their child are the result of sleep deficiency.
Over the last half century of observing children, I have developed a very low threshold for diagnosing sleep deprivation. Basically, any child who is cranky and not obviously sick is overtired until proven otherwise. For example, colic does not appear on my frequently used, or in fact ever used, list of diagnoses. Colicky is an adjective that I may use to describe some episodic pain or behavior, but colic as a working diagnosis? Never.
When presented with a child who has already been diagnosed with “colic” by its aunt or the lady next door, this is when the astute pediatrician must be at his or her best. If a thorough history, including sleep pattern, yields no obvious evidence of illness, the next step should be some sleep coaching. However, this is where the “until proven otherwise” thing becomes important, because not providing close follow-up and continuing to keep an open mind for the less likely coexisting conditions can be dangerous and certainly not in the patient’s best interest.
For the older child crankiness, temper tantrums, mood disorders and signs and symptoms often (some might say too often) associated with attention-deficit disorder should trigger an immediate investigation of sleep habits and appropriate advice. Less well-known conditions associated with sleep deprivation are migraine and nocturnal leg pains, often mislabeled as growing pains.
The physicians planning on using sleep as a therapeutic modality is going to quickly run into several challenges. First is convincing the parents, the patient, and the family that the condition is to a greater or lesser degree the result of sleep deprivation. Because sleep is still underappreciated as a component of wellness, this is often not an easy sell.
Second, everyone must accept that altering sleep patterns regardless of age is often not easy and will not be achieved in 1 night or 2. Keeping up the drumbeat of encouragement with close follow-up is critical. Parents must be continually reminded that sleep is being used as a medicine and the dose is not measured in hours. The improvement in symptoms will tell us when enough is enough.
Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.
