Adults with ADHD rarely fall asleep easily, sleep soundly through the night, and then wake up feeling refreshed. More often, ADHD’s mental and physical restlessness disturbs a person’s sleep patterns — and the ensuing exhaustion hurts overall health and treatment.
This is widely accepted as true. But, as with most of our knowledge about ADHD in adults, we’re only beginning to understand the stronger link between ADHD and sleep, that creates difficulties:Sleep disturbances caused by ADHD have been overlooked for a number of reasons.
Sleep problems did not fit neatly into the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM) requirement that all ADHD symptoms must be present by age 7.
Sleep disturbances associated with ADHD generally appear later in life, at around age 12, on average. Consequently, the arbitrary age cutoff has prevented recognition of night owls and sleep disturbances in ADHD until recently, when studies of adults have become more common.
