RESUMO

Congenital hypothyroidism (CH) is an important cause of preventable intellectual disability. Implementation of CH neonatal screening programs leading to early treatment has improved cognitive outcome. However, more subtle cognitive impairments are still reported, and there is lack of clarity regarding factors that impact long-term cognitive outcome. Research to better understand these factors can lead to further improvements in the cognitive prognosis for these patients. The current study aimed to evaluate the cognitive performance of adolescents who were early-treated for primary permanent CH and possible associated variables. Neurocognitive evaluation was carried out in 66 adolescents, 11 to 16 years old: 34 with CH and 29 paired controls. Intellectual quotient (IQ), verbal fluency, processing speed, executive functions, and memory were investigated. CH patients and control subjects were comparable regarding sex, age, schooling, family's socioeconomic status and caregiver's educational level. Both groups presented not only similar IQ scores but also equivalent performances regarding Perceptual Reasoning, Working Memory and Processing Speed index scores. Patients presenting different CH etiologies (dysgenesis and dyshormonogenesis) showed similar cognitive performance. Socioeconomic aspects along with the initial levothyroxine dose were the main variables to positively influence the cognitive performance, the family's socioeconomic status having the strongest association with patients' cognitive skills.

RESUMO

Children with ADHD and ASD may present differences in the affective-motivational processes. We systematically review the literature regarding temporal discounting in children up to 12 years with ADHD and ASD. Six articles were included, five studies with ADHD children (n = 231), one with ASD children (n = 21), all including typically developing children as controls (n = 210). Five studies (four with ADHD and one with ASD) found greater temporal reward discounting for clinical groups. Occurrence of ADHD appears to rush even more the decision-making process at this stage of development, but there is still a lack in the literature, especially evaluating individuals with ASD.
