== Physiological factors ==
There are several factor that can play a role in the sleep problems in children with ADHD:


== Mechanism of Injury / Pathological Process<br> ==
* It is possible that factors such as rapid eye movement (REM) sleep abnormalities, which are frequently observerd in children with ADHD<ref>Scarpelli S, Gorgoni M, D'atri A, Reda F, De Gennaro L.

Journal of Clinical Medicine. 2019; 8(10): 1737</ref>,may play a significant role. This is because REM is linked to parasomnias like nightmare disorder, which often lead to awakenings<ref>Bruni O, DelRosso LM, Melegari MG, Ferri R. The parasomnias. Child and Adolescent Psychiatric Clinics of North America. 2021; 30(1): 131-142</ref>, and it also affects neurobehavioral functioning in children with ADHD<ref>Kirov R, Brand S, Banaschewski T, Rothenberger A.

Background[edit | edit source]

Attention Deficit Hyperactivity Disorder (ADHD) is the most prevalent neurodevelopmental disorder in childhood. The prevalence of ADHD among preschool children is around 8%[1], with the disorder being three to nine times more common in males than females[2].

Quality sleep plays a crucial role in body repair, memory integration, brain information processing, and emotional regulation. All these aspects collectively have substantial effects on children's physical development, cognitive growth, emotional regulation, attention, behavior, metabolism, and immune function[3]. Poorer sleep is associated with worse academic performance[4].

Sleep problems are more common in children with ADHD (prevalence range from 30 to 74.6%, based on gender, age, ADHD subtype, co-morbidities, and use of medication[5]) than in children without ADHD[6][7][8][9][10][11][12][13]. Poor sleep quality and delayed bedtime can result in daytime fatigue, impacting mood, concentration, behavior, and physical health. Numerous studies have indicated a connection between sleep issues and heightened severity of ADHD symptoms or behavioral challenges in school-aged children with ADHD[7][14][15]. It is also associated with depressive symptoms[16], and poorer mental health of primary caregivers[17].

Physiological factors[edit | edit source]

There are several factor that can play a role in the sleep problems in children with ADHD:

  • It is possible that factors such as rapid eye movement (REM) sleep abnormalities, which are frequently observerd in children with ADHD[18],may play a significant role. This is because REM is linked to parasomnias like nightmare disorder, which often lead to awakenings[19], and it also affects neurobehavioral functioning in children with ADHD[20].

Sleep problems[edit | edit source]

The higher the ADHD symptoms. the more sleep problems a child has. Behavioral disruptions may affect sleep at night and functioning in the daytime in the following ways:

Gender[edit | edit source]

In the age group of 6-14 years, parents report a higher prevalence of sleep disorder symptoms in boys (5.19%) compared to girls of the same age (3.67%)[24], but there is also evidence that there is no significant difference between male and female children with sleep disorders[7].

Sleep hygiene[edit | edit source]

There are several sleep hygiene factors associated with the sleep quality of children with ADHD:

  • Co-sleeping (bed and room sharing): it has been linked to various sleep problems in children[25].

Other sleep associated factors[edit | edit source]

There are more factors that might contribute to sleep problems in children with ADHD:

  • Parents' own sleep behavior (sleep timing) might be associated with poorer quality sleep[26]

Outcome Measures[edit | edit source]

Interventions[edit | edit source]

The severity of ADHD can be reduced by improving the sleep of children with behavioral sleep interventions[7]. Other interventions might be:

  • Drug treatments
  • Non-pharmacological sleep-related interventions might be important for treating sleep problems including those that focus on sleep hygiene, sensory based factors, parental stress and eduction[27]
