They consist of impulse control disorders, dopamine dysregulation syndrome, and punding. The field continues to evolve in the understanding of impulsivity and assessment of risk factors in the development of these behaviours and their appropriate management in patients with Parkinson's disease. Recent findings Impulsivity is a multifaceted concept that is surprisingly common in untreated patients with Parkinson's disease. The incidence of ICBs increases with demographic, clinical, and biochemical risk factors. Treatments rely on reduction of dopamine agonists with exception of cognitive behavioural therapy and possibly repetitive transcranial magnetic stimulation. Summary Reduction of dopamine agonist dose is the mainstay of treatment of ICBs. Other forms of dopaminergic treatment such as deep brain stimulation or jejunal infusion are alternative treatments but may be complicated by dopamine agonist withdrawal syndrome. Other therapies show promise but data are insufficient to suggest their regular use. Copyright © 2015 Wolters Kluwer Health, Inc. All rights resereved.
