ESPE2021 ePoster Category 1 Thyroid A (10 abstracts)
Introduction: Thyroxine is important for nervous system development. Subclinical hypothyroidism (SCH), a mild thyroid dysfunction, is associated with impaired cognitive function in children and mood disorders in adults. Serotonin is also involved in brain development, mood and behavior modulation. The possible interaction between thyroid function tests, serum serotonin concentrations and emotional intelligence, was studied.
Methods: 224 schoolchildren from Peloponnese in Greece, aged 11-19 years old, were included into the study, of which 26.3% had SCH. Emotional quotients (EQ), such as well-being, self-control, emotionality and sociability were assessed using the TEIQue-ASF questionnaire, and TSH, fT4 and serum serotonin concentrations were also evaluated.
Results: Children and adolescents with SCH had lower EQ total score (P < 0.001), EQ Well-being score (P = 0.025), EQ Self-control score (P = 0.029), EQ Emotionality score (P = 0.029) and EQ Sociability score (P = 0.010) and lower serum serotonin concentrations (P < 0.001).
Conclusions: A possible association between TSH and serotonin levels is suggested affecting emotional intelligence scores in children and adolescents. Emotional intelligence seems to be negatively affected in children and adolescents with subclinical hypothyroidism. Further clarification of the role of thyroid hormones and serotonin in the developing brain is needed in order to elucidate the effect of a possible crosstalk between the hypothalamus-pituitary-thyroid axis and the serotonin pathway on emotional intelligence, cognitive ability and other potential brain functions in children and adolescents.
