Previous issue date: 2009-03-18 / Temperament is the automatic emotional and motivational bias, influencing mood, behavior and personality development. Thyroid dysfunction is more prevalent in patients with mood disorder and may interfere with treatment responsiveness, but the relationship between thyroid function and temperament has been less studied. Methods: 143 subjects (103 females) who completed the Combined Emotional and Affective Temperament Scale were evaluated for TSH, free T4 and free T3 levels. Results: There was a significantly higher proportion of cyclothymics than euthymics in the high TSH group (>4 mIU/L, p<0.05). Female volunteers with TSH<4 mIU/L had significantly higher scores for anxious and lower scores for irritable temperaments. Among volunteers with TSH<4 mIU/L, there was a positive correlation of free T4 with apathetic temperament score (r=0.23, p<0.01). This correlation persisted in males (r=0.33, p=0.037) and females (r=0.22, p=0=0.026) and if only volunteers with no medication at all were included (r=0.23, p=0.015, n=108).
Conclusion: Thyroid hormones seem to be associated with temperament in a non-linear way. Findings in patients with mood disorders and subclinical hypothyroidism cannot be generalized to understand the physiological role of thyroid hormones on emotion and affect. / O temperamento ? o vi?s autom?tico no terreno das emo??es e da motiva??o, influenciando humor, comportamento e o desenvolvimento da personalidade. A disfun??o da tireoide ? mais prevalente em pacientes com transtorno de humor e pode interferir na resposta ao tratamento. No entanto, a rela??o entre a fun??o da tireoide e o temperamento tem sido pouco estudada. M?todos: 143 sujeitos (103 mulheres) preencheram a Escala de Temperamento Afetivo e Emocional (ETAFE) e foram avaliados os n?veis s?ricos de TSH, T4 livre e T3 livre. Resultados: Houve uma propor??o significativamente maior de ciclot?micos do que eut?micos no grupo com TSH elevado (>4 mIU/L, p<0.05). Mulheres com TSH<4 mIU/L tiveram escores significativamente maiores de temperamento ansioso e menores de temperamento irrit?vel. Entre volunt?rios com TSH<4 mIU/L, houve uma correla??o positiva de T4 livre com escores de temperamento ap?tico (r=0.23, p<0.01). Esta correla??o persistiu em homens (r=0.33, p=0.037) e em mulheres (r=0.22, p=0=0.026) e na an?lise incluindo somente volunt?rios sem qualquer medica??o (r=0.23, p=0.015, n=108). Conclus?o: Os horm?nios tireoideanos parecem estar associados com o temperamento de modo n?o linear. Achados em pacientes com transtornos de humor e hipotireoidismo subcl?nico n?o podem ser generalizados para o entendimento do papel fisiol?gico dos horm?nios tireoideanos nos temperamentos afetivos e emocionais
