A fundamental understanding of normal sleep and wakefulness, along with related behavioral and physiologic variables, provides the basis from which sleep disorders in patients of all ages can be identified. It is also crucial that a sleep professional has a fundamental understanding of each sleep disorder as patterns and stages of sleep and wakefulness and the distribution, proportion and progression of different stages of sleep and wakefulness across a sleep episode develop and change from birth through old age.
I have delayed sleep phase disorder (DSPD). That means I am unable to fall asleep until very late at night and normally sleep very late in the morning. My sleep doctor sent me to a sleep lab to get a polysomnogram. The lab techs insisted I try to sleep at midnight, and they woke me at 5 a.m. The sleep doctor then informed me that my problem was I wasn’t getting any deep sleep. No, not between midnight and 5 a.m.—I could have told her that.
