Can ADHD Cause Excessive Sleepiness?
Attention-deficit/hyperactivity disorder (ADHD) is often associated with hyperactivity and restlessness, but many individuals with ADHD also experience significant fatigue and daytime sleepiness.
In some cases, people with ADHD may struggle with hypersomnia—a condition characterized by excessive daytime sleepiness, prolonged sleep, or difficulty staying awake during the day.
This connection is often misunderstood because ADHD is typically viewed as a disorder of “too much energy,” when in reality sleep and attention regulation are deeply connected.
