Recently a study was done to evaluate the relationships between circadian typologies, insomnia, and internet gaming disorder and how ADHD affects this relationship.

Researchers took three groups of 69 young adults (Lin et al., 2023) :

A group with Internet Gaming Disorder
A control group - comprising age and sex-matched nongamers
A group of gamers without IGD was established through diagnostic interviews.

The participants with IGD exhibited lower composite scale of morningness scores and thus a higher eveningness preference (Lin et al., 2023).
The group with IGD scored higher on the Pittsburgh insomnia rating scale.
The participants with IGD and ADHD exhibited lower CSM scores but higher PRIS_20 scores than the participants with IGD but without ADHD (Lin et al., 2023).

🟥These findings indicate that participants with IGD experienced more severe insomnia and preferred to be awake more in the evening.
🟥ADHD exacerbated the eveningness preference and insomnia of the subjects with IGD.
🟥The study suggests that we need to pay close attention to sleep problems in people with IGD and especially in those with ADHD

🟥Why is this study important?

Well gaming technology has advanced considerably in recent decades, and more people have access to the internet. And now there is a new global mental health concern which is Internet Gaming Disorder or IGD.
The DSM-5-TR notes that IGD must cause "significant impairment or distress" in several aspects of a person's life ( 2023).
Scholars have found that excessive internet gaming is associated with maladaptive gaming beliefs and can lead to psychological consequences such as depression and interpersonal impairment
Because inadequate or nonrestorative sleep can remarkably reduce a person’s quality of life, understanding the association between IGD and sleep is crucial. Research has indicated that IGD is related to low sleep quality, limited sleep time, and subjective insomnia. Insufficient experimental evidence is currently available regarding the sleep patterns of individuals with IGD.

🟥Therefore understanding circadian typologies among individuals with IGD is essential
