Gambling Disorder during Dopamine Replacement Treatment in Parkinson’s Disease : A Comprehensive Review

Abstract EN

Gambling Disorder (GD) is characterized by “the failure to resist gambling impulses despite severe personal, family or occupational consequences”.

In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), GD replaces the DSM-IV diagnosis of Pathological Gambling (PG).

GD estimated prevalence ranges between 0.4% and 3.4% within the adult population and it seems to be more common in patients with Parkinson’s disease (PD).

In this population, GD recently has become more widely recognized as a possible complication of dopamine agonist (DA) therapy.

This association has aroused great interest for the dramatic impact GD has on patients’ quality of life.

Management of PG in patients with PD could be demanding.

It is based on patient and caregiver education, modification of dopamine replacement therapy, and in some cases psychoactive drug administration.

In this review article, the authors provide an overview of GD pathogenesis during DA therapy as well as a summary of available treatment options.
