Summary
Computerized response inhibition training (RIT) shows promise for treating trichotillomania in children. This intervention improved symptoms and reduced impairment, with gains maintained at follow-up.
Area of Science:
- Child Psychiatry
- Neuroscience
- Behavioral Therapy
Background:
- Trichotillomania is linked to impaired response inhibition.
- Developing effective interventions for pediatric trichotillomania is crucial.
Purpose of the Study:
- To assess the feasibility of computerized response inhibition training (RIT) for children with trichotillomania.
- To evaluate the efficacy of RIT compared to a waitlist control.
Main Methods:
- A randomized controlled trial involving 22 children with trichotillomania.
- Participants were assigned to 8 sessions of RIT or a waitlist control (WLT).
- Outcomes measured using Clinical Global Impression-Improvement (CGI-I), NIMH Trichotillomania Severity Scale (NIMH-TSS), and NIMH Trichotillomania Impairment Scale (NIMH-TIS).
Main Results:
- The RIT group demonstrated significantly higher response rates (55% vs. 11%) on CGI-I and reduced impairment (NIMH-TIS) post-intervention.
- Symptom reduction on NIMH-TSS was 34% in the RIT group versus 21% in the WLT group.
- Therapeutic gains were sustained at 1-month follow-up, with 66% of RIT participants maintaining responder status.
Conclusions:
- Computerized RIT is a potentially effective and feasible intervention for pediatric trichotillomania.
- RIT may improve response inhibition, leading to reduced symptoms and impairment.
- The positive effects of RIT are durable and maintained over time.

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
