Vignettes - Gambling

“My father has been treated for Parkinson’s since his diagnosis in his late 40’s, over 25 yrs ago. He has developed a severe compulsive gambling problem over the years… such that he is now destitute and broke. He owned multiple successful automobile dealerships and has been on the board of the bank for many years…His disease has required increasing amounts of multiple meds, including dopaminergic drugs…The following year he (the neurologist) said it was a known effect but knew of no treatment…I am concerned about suicide…I am wondering from all I have read this week if there is a compulsion drug he can be treated with for this…Some recommend weaning off the dopaminergic drugs. I am not sure how this would go for him.”

Vignettes – Eating and Sex

“During the day I can control my appetite and I have will power. Then in the evening right before bed time it starts and I feel the urge to eat. I have gained 15 lbs and I have been thin all my life so this is a shock for me. Now I am on a diet, it’s slow because I keep wanting to eat…When I wake up in the morning I see the number of wrappers that are at the bed side and it is a shock.”

“It is like an urge that you just cannot satisfy. It happens at night when

I am alone. I often go on the internet and look at websites that are sexual in nature. It causes me to lose a lot of sleep. The lack of sleep is causing problems at work; some people are starting to notice that I am exhausted in the afternoon… I am not as productive as I was before… I have let a lot of things (around the house) go because I spend my time fantasizing and on the internet.”

Issues Highlighted by Cases

•  Association with PD medications •  Behaviors atypical or excessive for individual •  Lack of control over behaviors •  Lack of pleasure associated with behaviors • “Needing” vs. “wanting”

•  Significant distress or impairment in many cases, often enduring

•  Difficult clinical management decisions

Page 8: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Terminology •  Impulse control disorders (ICDs) are category of

psychiatric disorders in DSM-IV – Essential feature “failure to resist impulse, drive, or

temptation to perform act that is harmful to person or others”

•  ICDs accepted as term for major disorders reported to occur in PD – Gambling – Buying – Sexual behaviors – Eating

Page 9: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Presentation •  Gambling

– Can involve frequent low stakes (slots, scratch cards), casinos

•  Sexual behavior – Demands on spouse, internet, prostitution, changes

in sexual orientation •  Buying

– Purchasing same items repeatedly •  Eating

– Cravings for certain foods (sweets), overnight eating

Page 10: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Related Disorders

•  Dopamine dysregulation syndrome (DDS) –  More like addiction

•  Misuse and escalating dose of medication –  Occurs with levodopa or subcutaneous apomorphine

typically –  Appears less common in US than in Europe

•  Punding (fascination with meaningless objects or activities) •  Hobbyism (more complex task preoccupation) •  Walkabout •  Other (hoarding, reckless driving)

Page 11: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Beneficial Changes in Behaviors? •  Increased sexual drive in patients with decreased

sexual drive and performance? •  Increased appetite in patients that lose weight? •  Enhance creativity? •  Increased motivation in patients with apathy or

avoidance? •  Increased enjoyment?

These possibilities have not been adequately explored in Parkinson’s disease.

DOMINION Study

•  Study of frequency and correlates of 4 ICDs in PD – MAGS for gambling, MIDI for buying and sexual

behavior, and DSM-IV criteria for binge-eating •  46 PD centers in US and Canada •  3090 patients ≤75 years old completed assessments •  66% of patients were taking a dopamine agonist (DA)

– Overall, 86.8% of patients were taking levodopa

Weintraub et al. Archives of Neurology 2010;67:589-595.

Page 15: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Frequency of ICDs

•  At least one ICD identified in 14% of patients –  29% of ICD patients had ≥2 ICDs

•  Frequencies of individual ICDs were: – Problem/pathological gambling = 5.0% – Compulsive sexual behavior = 3.5% – Compulsive buying = 5.7% – Binge-eating disorder = 4.3%

Dose Effects

•  Examining patients on a DA (N=2040) – No DA dosage effect – There was levodopa dosage effect (P=0.008)

•  Examining patients on levodopa only (N=991) – Higher levodopa dosage was associated with

current ICD (P=0.002)

Page 21: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Other Factors Associated with ICDs •  ICDs more common in US (15.0%) than Canada

(9.8%) – Specifically compulsive gambling and buying – Even controlling for differences in medication

exposure •  No sex differences in ICDs overall, but

– Sexual behaviors far more common in men – Buying and binge-eating more common in women

•  Family history of gambling problems more common in three of the four ICDs (all except sexual behaviors)

Assessment

Page 24: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s Disease (QUIP)

•  Valid as screening instrument for ICDs and related disorders

•  Simple and short (<5 minutes) •  Clinical interview needed for screen + patients •  Interview should focus on all ICDs and related

behaviors

Management

Page 28: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Current Management Options •  Do nothing

– Assess clinical significance – Some patients unable or reluctant to make

adjustments to PD pharmacotherapy •  Alterations to PD pharmacotherapy

– Changes to DA therapy with increase in levodopa to help motor symptom management

•  Consider deep brain stimulation (DBS) •  Psychopharmacology

– Antidepressants, antipsychotics

Amantadine for Gambling in PD

Thomas et al. Annals of Neurology 2010;68:400-404.

Symptom Assessment Scale (SAS) and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score changes. Both scores reduced by amantadine (p < 0.001 compared to baseline). A = amantadine P = placebo

Ongoing Clinical Trial •  Michael J. Fox Foundation grant •  Randomized, double-blind, placebo-controlled

clinical trial of naltrexone for all ICDs – Naltrexone is an opioid receptor anatagonist FDA-

approved for the treatment of alcoholism – Modulatory role for opioid peptides in the

nigrostriatal dopaminergic pathway •  48 subjects with ≥1 of 4 common ICDs

Conclusions - Epidemiology •  ICDs in PD are

– Relatively common – A range occur – Often co-morbid – Psychiatric co-morbidity common – Associated with DA use as a class – Associated with levodopa and amantadine use to

lesser extent – Dose effects for levodopa – May have other “pre-morbid” risk factors

Page 32: Impulsive and Compulsive Behaviors in Parkinsonʼs Disease...Impulsive and Compulsive Behaviors in Parkinsonʼs Disease Presented By:! Daniel Weintraub, M.D.! Associate Professor of

Conclusions – Assessment and Management •  Must ask about a range of symptoms •  Agreement fair between patients and informed others •  Screening instruments and rating scales available for

clinical use •  Range of management strategies available

– Need for psychopharmacological options with established efficacy and good tolerability
