Tasks measuring mainly attention, object and space perception and executive functions adequately assess the progression of HD disease. Other cognitive functions do not significantly deteriorate. Furthermore, problems in attention, working memory, verbal learning, verbal long-term memory and learning of random associations are the earliest cognitive manifestations in AC.

One year of Cr intake, at a rate that can improve muscle functional capacity in healthy subjects and patients with neuromuscular disease (5 g/day), did not improve functional, neuromuscular, and cognitive status in patients with stage I to III HD.

Cognitive impairments in HD patients are found when compared with clinically asymptomatic individuals carrying the HD mutation. Furthermore, our results suggest that subtle cognitive deficits are present in asymptomatic persons who have inherited the HD gene.

These results suggest that the commonly used IOTN as a clinical assessment tool for orthodontic treatment need should be reinforced by OHRQoL measures, like the OASIS, expressing patients' perceived treatment need.

No Escape compared to Escape Delay trial cues in the insula, amygdala, ventral striatum and orbito-frontal cortex. Conclusion:The results of this pilot study provides further evidence for the role of altered motivational systems in ADHD and the most direct evidence for a biological basis of delay aversion.

The interest in the psychological aspects of orthodontic treatment increases, but a drawback of many studies is that the psychological characteristics of the children themselves are often ignored. One of these psychological attributes is self-esteem (SE), which is a relatively stable personal resource that might moderate the effects of conditions or events. The aim of this study was to investigate whether there is a relationship between orthodontic treatment need and oral health-related quality of life (OHRQoL) and whether this relationship is influenced by SE. This cross-sectional study comprised 223 children (113 boys and 110 girls) between 11 and 16 years of age (mean age 13.2 years), seeking orthodontic treatment. The OHRQoL was scored by the use of the Child Perception Questionnaire (CPQ(11-14)). The Dutch adaptation of the Harter's Self-Perception Profile was used to assess SE, and the Index of Orthodontic Treatment Need defined the need for treatment. Spearman correlations, Mann-Whitney U-tests, and regression models were used to analyze the data. There was a significant relationship between orthodontic treatment need and OHRQoL, and between SE and OHRQoL. No evidence was found that SE moderates the relationship between OHRQoL and treatment need.
