Impulse control disorders (ICDs) are nonmotor complications of dopaminergic medications characterized by problems in behavioral self-control. Common management involves discontinuing or lowering dopaminergic medication, often producing motor worsening. We performed a retrospective chart review of Parkinson's disease (PD) patients treated with clozapine for ICDs. Four patients treated with clozapine for ICD were identified. Three patients were men. All 4 took dopaminergic medications at the time that ICDs developed; all received dopamine agonist therapy. ICDs included compulsive shopping, binge drinking, and hypersexuality. All 4 patients had complete resolution of symptoms while taking clozapine (12.5-37.5 mg). Two patients discontinued clozapine because of side effects. Larger studies are needed to further evaluate clozapine's role in treating PD patients with ICD.

Effects of parental psychological control on mobile phone addiction among college students: the mediation of loneliness and the moderation of physical activity.
BMC Psychol

School of Physical Education, South China University of Technology, Guangdong, Guangzhou, P.R. China.
Objective: Prior studies have shown that parental psychological control is linked to an increased risk of mobile phone addiction. Nevertheless, few studies have analyzed the potential mechanisms that may mediate or moderate this association. This study aims to investigate the role of loneliness as a mediator in the relationship between parental psychological control and mobile phone addiction, as well as the potential moderating effect of physical activity on this mediation process.

Background: Knowledge is growing on the essential role of neural circuits involved in aberrant cognitive control and reward sensitivity for the onset and maintenance of binge eating.
Aims: To investigate how the brain's reward (bottom-up) and inhibition control (top-down) systems potentially and dynamically interact to contribute to subclinical binge eating.
Method: Functional magnetic resonance imaging data were acquired from 30 binge eaters and 29 controls while participants performed a food reward Go/NoGo task.
Evaluating remyelination compounds for new applications in opioid use disorder management.

Opioid use disorder (OUD) is associated with a reduction in brain white matter, affecting critical areas involved in decision-making, impulse control, and reward processing. The FDA has approved several drugs and natural compounds that enhance myelination, targeting oligodendrocyte progenitor cells (OPCs), directly enhancing oligodendrocyte (OL) function, or acting as cofactors for myelin production. This retrospective case study aimed to assess whether current clinical evidence supports the use of myelin-enhancing agents to promote remission in OUD.

Hemorrhagic fever with renal syndrome (HFRS) caused by hantavirus is prevalent across China and causes a significant number of deaths every year. This study aims to examine the transmission dynamics of hantavirus and to suggest effective control measures. We extend a periodic model of HFRS infection including house/field mice, contaminated environments, and the human population by introducing nonlinear pulses used to describe impulsive interventions.
