RESUMO
OBJECTIVES: Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurobehavioral disorder in school-aged children. Although there are several drug treatment options, some patients do not have adequate therapeutic responses to conventional medications or experience considerable adverse effects. Citicoline is an endogenous molecule that has beneficial effects on attention, impulsivity, and memory and is a potential treatment for ADHD. This study aimed to evaluate the effect of citicoline in pediatric patients diagnosed with ADHD. METHODS: This randomized, crossover, double-blind, placebo-controlled clinical trial included with patients aged 7-12 years diagnosed with ADHD. RESULTS: As a result, no statistically significant difference was noted between the use of citicoline and placebo in the evaluated parameters. The treatment had no adverse effects. CONCLUSIONS: Citicoline seems to be a safe molecule to be administered in the pediatric age group. Further studies are required to assess the therapeutic potential of citicoline in ADHD.
RESUMO
Objective: As the older population increases, it is important to identify factors that may reduce the risks of dementia in the general population. One such factor is the concept of cognitive reserve (CR). The present study analyzed the psychometric properties of the Cognitive Reserve Assessment Scale in Health (CRASH) in the Brazilian population. This scale was originally developed to measure CR in individuals with severe mental illness. We also investigated the relationship between the CRASH and clinical or sociodemographic variables. Methods: This study was conducted with 398 individuals. We assessed sociodemographic variables and depression, anxiety, and stress symptoms (Depression, Anxiety and Stress Scale [DASS-21]) using a web-based survey. We constructed a confirmatory factor analysis (CFA) model in order to test the goodness of fit of the factor structure proposed in the original CRASH study. Results: The McDonald's hierarchical ω for CRASH using CFA parameters was 0.61, and the Cronbach's alpha coefficient indicated good internal consistency when considering all items (alpha = 0.7). Conclusions: Our results suggest that CRASH can be used to assess CR in the general population in Brazil.
