The Developmental Medicine & Child Neurology review notes that the tentative definition of IGD in the
Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM - 5) is a good starting point for diagnosing the condition, with the most stringent
criteria including a build - up of tolerance (more time needs to be spent playing computer games), loss of control, giving up other interests, and excessive use despite
clear - cut psychosocial and health - related problems.
