Prevalence studies suggest that ICDs occur in 13.6–36.0% of Parkinsons patients exhibited at least one form of ICD. There is a significant co-occurrence of pathological gambling and personality disorder, and is suggested to be caused partly by their common "genetic vulnerability". The degree of heritability to ICD is similar to other psychiatric disorders including substance use disorder. There has also been found a genetic factor to the development of ICD just as there is for substance use disorder. The risk for subclinical PG in a population is accounted for by the risk of alcohol dependence by about 12–20% genetic and 3–8% environmental factors. There is a high rate of co-morbidity between ADHD and other impulse-control disorders. Mechanism
Dysfunction of the striatum may prove to be the link between OCD, ICD and SUD. According to research, the impulsiveness that occurs in the later stages of OCD is caused by progressive dysfunction of the ventral striatal circuit. Whereas in case of ICD and SUD, the increased dysfunction of dorsal striatal circuit increases the "ICD and SUD behaviours that are driven by the compulsive processes". OCD and ICD have traditionally been viewed as two very different disorders, the former one is generally driven by the desire to avoid harm whereas the latter one driven "by reward-seeking behaviour". Still, there are certain behaviors similar in both, for example the compulsive actions of ICD patients and the behavior of reward-seeking (for example hoarding) in OCD patients. Treatment
Impulse-control disorders have two treatment options: psychosocial and pharmacological.
The efficiency of cognitive behavior therapy for compulsive buying is not truly determined yet; however, common techniques for the treatment include exposure and response prevention, relapse prevention, cognitive restructuring, covert sensitization, and stimulus control. See also
