People with ADHD often experience difficulties both falling and staying asleep . This exacerbates the disorder's symptoms, causing impaired cognitive function, as well as increased daytime sleepiness, restlessness, and impulsivity. These symptoms, related to a lack of restorative sleep, are also associated with a higher risk of developing other psychiatric disorders such as anxiety or depression.

Therefore, it is important not to underestimate the importance of sleep quality in these individuals, and if a persistent pattern of poor sleep or insomnia is detected, a specialist should be consulted. Treatment for these sleep disorders is usually behavioral, with implementing good sleep hygiene being the first recommended approach.
