Punding is a term that was coined originally to describe complex prolonged, purposeless, and stereotyped behaviour in chronic amphetamine users. A structured interview of 50 patients with higher dopamine replacement therapy requirements (>800 levodopa equivalent units/day) from 123 unselected patients with Parkinson's disease (PD) from a PD clinic identified 17 (14%) patients with punding. Punding was acknowledged as disruptive and unproductive by the patients themselves, but forcible attempts… 
Punding in non-demented Parkinson's disease patients: Relationship with psychiatric and addiction spectrum comorbidity
TLDR
Present data confirm that DRT, in a subset of PD patients, is strongly associated with addiction-like behavioral issues and is associated to other psychiatric symptoms involving dopamine system alterations.
Impulse control dysfunction and dopamine agonist withdrawal syndrome in Genetic Parkinson’s: A case report
Abstract Impulse control disorders (ICD) and punding have emerged as one of the most significant challenges to modern dopaminergic treatment, particularly those involving dopamine agonist (DA) drugs
Impulse control disorders and punding in Parkinson's disease: the need for a structured interview.
Abstract Introduction Impulse control disorders (ICD), including hypersexuality, compulsive gambling, buying, eating, shopping and dopaminergic medication use, have been reported to occur frequently
Predictors of punding in Parkinson's disease: Results from a questionnaire survey
TLDR
Higher impulsivity, poorer disease‐related quality of life, younger age of disease onset, and concomitant daily medication dosage from dopamine receptor agonists were independently predictive of higher Punding Scale scores in the PD group, providing further evidence for the role of impulsivity and age at disease onset in DRT‐related nonmotor behavioral problems in PD.
Punding and computer addiction in Parkinson's disease
TLDR
A man with PD who developed an unusual, severe, repetitive behavior characterized by spending most of his time on his computer was reported, which was concomitant with the introduction of L‐dopa (400 mg per day) and was not associated to a pattern of chronic inappropriate overuse of dopaminergic medication or other psychiatric symptoms.
Compulsive use of dopaminergic drugs in Parkinson's disease : a window into the role of dopamine in addiction and impulse control disorders
Parkinson's disease (PD) is a progressive condition that often requires specialist care for a variety of motor and nonmotor symptoms. These symptoms arise from the disease process and also the
Addictive behaviors and Parkinson's disease.
TLDR
The recognition of these behaviors is important and allows a better clinical management, and some approaches are worth considering: DRT reduction, trials of non-dopaminergic medications and subthalamic chronic stimulation.
Parkinson’s disease-related disorders in the impulsive-compulsive spectrum
TLDR
In Parkinson’s disease, there is increasing evidence for disorders in the impulsive-compulsive spectrum, related to the disease itself, to the pharmacological management of this disease or to both and impulse control disorders are suggested as being pure adverse side-effects of dopamine replacement therapy.
Impulsive compulsive behaviours in Parkinson's disease : an observational, eye movement and neuropathological study
TLDR
Lower levels of alpha-synuclein were found in the nucleus accumbens of patients with ICBs suggesting a central role for this structure in the pathophysiology of ICBs.
Spectrum of addictions in Parkinson’s disease: from dopamine dysregulation syndrome to impulse control disorders
TLDR
The management for clinically significant ICD symptoms should consist of modifications to dopamine replacement therapy (DRT), particularly DAs, which is usually associated with an improvement of ICDs, whereas there is no empiric evidence supporting the use of psychiatric drugs in I CDs in PD.

Hedonistic homeostatic dysregulation in patients with Parkinson's disease on dopamine replacement therapies.
TLDR
Hedonistic homeostatic dysregulation is a neuropsychological behavioural disorder associated with substance misuse and addiction that develops in male patients with early onset Parkinson's disease, and can occur with orally and subcutaneously administered DRT.

TLDR
Cocaine-induced paranoia is a common experience among chronic users and amount and duration of use are related to its development.

TLDR
The findings have some important implications: drug addiction, basic understanding of social behavior and mental functions, screening and use of neuroleptic drugs, and side effects on social contact and behavior by the therapeutic use of CNS stimulants.
Characteristics of obsessive–compulsive symptoms in Tourette's syndrome, obsessive–compulsive disorder, and Parkinson's disease
TLDR
Considering specific patterns of obsessive-compulsive psychopathology may contribute to a more reliable differential diagnosis in OCD and TS and help to avoid misdiagnosis of OCD in TS patients.
Association of obsessive‐compulsive disorder and pathological gambling with Huntington's disease in an Italian pedigree: possible association with Huntington's disease mutation
TLDR
A pedigree with Huntington's disease (HD), in which three cases of obsessive‐compulsive disorder (OCD) and two cases of pathological gambling (PG) were identified, found that OCD and PG only occurred in carriers of the HD expansion.
Impulsivity resulting from frontostriatal dysfunction in drug abuse: implications for the control of behavior by reward-related stimuli
TLDR
The neuro-anatomical and neurochemical substrates subserving inhibitory control and motivational processes in the rodent and primate brain and their putative impact on drug seeking are considered and an integrative hypothesis for compulsive reward-seeking in drug abuse is presented.
Toward a Neurobiology of Obsessive-Compulsive Disorder
TLDR
These studies suggest that, with experience, striatal neurons can develop new responses to environmental stimuli, and this plasticity is likely to affect basal ganglia circuits in OCD and related disorders.
