1 Spectrum of

Behavioral Addictions 3

Why did it take us that long?

Impulse Control Disorders, Substance Use Disorders, Somatoform Disorders, and Behavioral Addictions

The tobacco companies, the lawsuits, and organized medical professional organizations.

The DSM-5 4

Essential Features

Failure to resist an impulse, drive, or temptation

to perform an act that is harmful to the person or others.

5

Impulsivity vs. Compulsivity

Both show inability to refrain from repetitive behaviors.

Impulsivity is driven by an effort to obtain arousal and gratification.

Compulsivity is driven by an effort to reduce anxiety.

Epidemiology

US Gambling Statistics:

$ 36 billion/year casino revenue (2011 data). 82% of US residents gamble. 1% - 3% meet criteria for PG.

Pathological Gamblers:

$ 40,000 average individual debt. 25 hours/week average time spent.

Screening Tools The Lie/Bet Test

Have you ever felt the need to bet more and more money?

Have you ever had to lie to people important to you about how much you gambled?

.99 sensitivity, .91 specificity.

What would you do?

1. Switch.

2. Stick to my original choice.

3. It doesn’t matter; either way my chance of winning is 50%.

Interpretative Biases

Attributing wins to skill, losses to flukes

Wrongly believing that a series of losses increases the chance of subsequent win

The “Sunk-Cost” effect

Near misses

20

Near Misses: Of Mice and Men

“Why Mice are Smarter than Men?”

“But I was only one number away from winning the lottery!”

Free dinner on my birthday.

Interpretative Biases

21

Superstitious Beliefs

Believing in: good luck objects (like animal parts), behaviors, routines.

Gaboury A, Ladouceur R: Erroneous perceptions and gambling. Journal of Social Behaviors and Personality 4:411-420, 1989.

22

Selective Memory

Remembering wins while ignoring losses.

Totaling wins without correcting for amounts lost.

23

Telescoping

Temporal: Expecting that naturally occurring—that

is, probabilistically expected—wins will happen sooner rather than later.

Reference: Expecting that naturally occurring—that

is, probabilistically expected—wins will happen to oneself rather than others.

4 Body Dysmorphic

Disorder 25

26

27 27

1. Preoccupation with one or more perceived defects or flaws that are not observable or appear slight to others.

Pathological Gambling

Adapted from: Hollander E, Clinical Manual of Impulse-Control Disorders, 2006.

41

PG as an Impulsive Disorder

Opioid Antagonists Naltrexone and Nalmefene. Block opioid receptors, decrease

dopamine function, and reduce “Reward Cravings.”

Best with family history of alcoholism.

Grant JE, Potenza MN: Pathological Gambling: A Clinical Guide to Treatment. Washington, DC, American Psychiatric Publishing, 2004.

42

Selective Serotonin Reuptake Inhibitors Fluvoxamine, Paroxetine, Escitalopram. Block serotonin reuptake, increase

serotonin function, and reduce “Self-Medication.”

Best with co-occurring depression or anxiety.

6 Conclusions

46

1. Behavioral addictions fall within an impulsivity-compulsivity spectrum of illness.

2. Gambling Disorder is now one of the “Substance-Related and Addictive Disorders.”

3. Body Dysmorphic Disorder falls under the DSM-5 “Obsessive-Compulsive and Related Disorders” chapter.

4. Antidepressants have shown efficacy for BDD, but not for Gambling Disorder.
