CHAPTER 11: Substance-Related, Addictive, and Impulse-Control Disorders
➢ DSM 5 changes: they’ve lumped together what used to be the impulse-control disorders and substance-
related disorders
➢ Gambling looks a lot like an addictive behavior. It has the same sorts of biochemical changes that
occur. It looks more and more like an addiction and has been treated in addiction centers for a long time
as an addiction
➢ So now this new category lumps all those 3 things together
Addictive and Impulse-Control Disorders
➢ problems related to the use and abuse of psychoactive substances
o wide-ranging physiological, psychological, and behavioral effects
➢ gambling also included in this category
➢ includes impulse-control disorders
o intermittent explosive disorder, kleptomania, pyromania

something. There needs to be a regular pattern
➢ substance abuse versus substance dependence

Substance Use Disorders
Tolerance, defined as either:
➢ a need for increased amounts of the substance to achieve desired effect, or
➢ diminished effect with continued use of the same amount of the substance
Withdrawal, manifested as either:
➢ the characteristic withdrawal syndrome for the substance (typically opposite to the drug effects. If you’re
taking a sedative for example, when you stop it, you get anxious and wound up)
➢ OR
➢ Using the same (or a closely related) substance to relieve or avoid withdrawal symptoms
o you may not actually experience the withdrawal syndrome
o DSM 4 you used to have to specify whether somebody with this disorder met criteria
