Behavioral addictions

Here's a fact examiners love because it surprises people: as of the DSM-5-TR, there is exactly one officially recognized behavioral (non-substance) addiction — gambling disorder. Everything else you hear called an "addiction" (internet, gaming, shopping, sex) is emerging, not officially diagnosable as a behavioral addiction. Get that count right and you've got the core of this topic.

Gambling disorder earned its place because the research showed it behaves like a substance addiction — it activates the same brain reward systems, and clients report tolerance (needing to bet more money for the same thrill), withdrawal-like restlessness/irritability when trying to cut down, preoccupation, chasing losses, lying to conceal involvement, and jeopardizing relationships or jobs. That's why DSM-5 moved it out of the old "impulse-control disorders" category and into "Substance-Related and Addictive Disorders."

The emerging patterns to know: Internet Gaming Disorder appears in the DSM-5-TR Section III as a condition for further study — meaning it is not yet an official diagnosis. (The WHO's ICD-11, separately, did formally recognize Gaming Disorder — a common exam contrast.) Other proposed-but-unofficial behavioral addictions include compulsive internet use, shopping, exercise, and sexual behavior — recognize them as not DSM-diagnosable behavioral addictions.

The shared logic across behavioral addictions is that a rewarding behavior — not a substance — becomes compulsive despite mounting harm, following the same loss-of-control pattern.

Clinical Pearl: The single highest-yield fact: gambling disorder is the ONLY DSM-5-TR-recognized behavioral addiction, and it was reclassified from impulse-control disorders into the addictive-disorders chapter. Internet gaming is only a Section III "condition for further study" in the DSM (though ICD-11 does recognize it).
