"Compulsive Shopping" is characterized by poorly controlled preoccupations/urges/behaviors focused on shopping and spending, causing significant distress/impairment. This study looked at what roles executive and related memory problems might exist in compulsive shopping. 205 adults completed on-line questionnaires measuring compulsive shopping, mood, as well as working memory and inhibition components of executive function. The was used to assign participants to either a (HCS) group or (LCS) group. Working memory (WM) and inhibition control (IC) were measured as two components of executive function (EF) using the (ADEXI), the DEX-R) measured general EF. The measured anxiety and depression. MANCOVA and mediation analyses were carried out controlling for age, gender, anxiety, depression. The HCS group scored significantly higher on all three EF measures, indicating greater executive difficulties. Subsequent mediation analyses with the ADEXI-IC as the mediator removed the significance of the relationship between Group and both the DEX-R and ADEXI-WM outcome variables. Thus, observed Group difference in DEX-R and ADEXI-WM could be fully accounted for by group differences in inhibitory control. The results highlight the role inhibitory control plays in compulsive shopping.

Impulse control disorders in Parkinson's disease: What's new?

Impulse Control Disorders (ICDs) are increasingly recognized as a significant non-motor complication in Parkinson's disease (PD), impacting patients and their caregivers. ICDs in PD are primarily associated with dopaminergic treatments, particularly dopamine agonists, though not all patients develop these disorders, indicating a role for genetic and other clinical factors. Studies over the past few years suggest that the mesocorticolimbic reward system, a core neural substrate for impulsivity, is a key contributor to ICDs in PD.

Article Synopsis
- Gambling disorder is the only recognized behavioral addiction in DSM-5, while Internet gaming disorder is noted for further research; other potential disorders include compulsive sexual behavior, compulsive shopping, and social media issues.
- These disorders are clinically relevant and often coexist with conditions like depression and anxiety, with validated diagnostic tools available but no approved medications for treatment.
- Cognitive-behavioral therapy shows the most promise, highlighting the need for active screening and public health efforts, along with further research into treatment methods that combine various therapeutic approaches.

Article Synopsis
- Parkinson's disease is a neurodegenerative condition that often includes psychiatric symptoms like anxiety and depression in over 60% of patients, leading to a high risk of impulse control disorders (ICDs) such as compulsive shopping and gambling.
- A study conducted over six years explored pharmacological treatments for ICDs among Parkinson's patients, using the Hamilton Rating Scale to evaluate their symptoms and outcomes.
- The results showed a reduction in impulsive behaviors among patients, and the article discusses potential future research directions to further address these symptoms.

Healthy action selection relies on the coordinated activity of striatal direct and indirect pathway neurons. In Parkinson's disease (PD), in which loss of midbrain dopamine neurons is associated with progressive motor and cognitive deficits, this coordination is disrupted. Dopamine replacement therapy can remediate motor symptoms, but can also cause impulse control disorder (ICD), which is characterized by pathological gambling, hypersexuality, and/or compulsive shopping.

Hoarding disorder (HD) represents a growing public health burden. Although excessive saving is the cardinal feature of this disorder, hoarding is also typically characterised by excessive acquisition of objects, either passively or actively. HD and a related clinical condition, compulsive buying-shopping disorder, are particularly challenging to prevent and treat within the context of consumer society, which is marked by growing acquiring tendencies.
