Prior to the release of the DSM-5 in 2013, Pathological Gambling was classified as an impulse control disorder. This diagnosis is made when a person is unable to resist impulses to participate in gambling activities even though doing so has resulted in negative consequences.
In the DSM-5, this disorder has been reclassified to be an Addiction Disorder. Gambling disorder was included in Addictions because it has been well researched and neurological similarities between gambling addiction and drug addiction have been found. There also appears to be a genetic basis as well with gambling disorder (APA, 2013).
