Narcolepsy and ADHD
“Our 22-year-old son was recently diagnosed with inattentive ADHD. Three months earlier, he was diagnosed with narcolepsy. Did the onset of narcolepsy bring out the ADHD?”
Narcolepsy can have its onset in early adulthood. Not so with ADHD, a chronic and pervasive disorder with behaviors noted from the earliest school years. They would not first appear at age 20 or 21. Discuss your question and concerns with the physician who made the diagnosis.
