Although there isn't a specific medication for gaming disorders per se, Dr. Poznyak says that there are treatment options that can help children to alleviate their suffering.
If you suspect your kiddo has a gaming disorder, making an appointment with a cognitive behavioural therapist might be your best bet. Dr. Poznyak also says that psychosocial interventions such as "social support, understanding of the conditions, family support" can also help those who are suffering from gaming disorders.
