Hypothyroiidism suggest that TSH levels are correlated to the severity of depressive symptoms. Reasons, why hypothyroid patients may have a poor wellbeing due to thyroxine, are numerous and a possible explanation is the misattribution of symptoms.

Overview of Thyroid Hormone Metabolism in the Brain The hypothalamic-pituitary-thyroid axis HPT is a complex interplay between several factors: thyroid hormones, deiodinase enzymes, transporter proteins, and receptors. Because of the relatively small number of patients with myxedema coma, controlled studies comparing various dosages of T 4 and T 3 are lacking.

Myxedematous hypothyroidism and depression hypkthyroidism is related to clinical recovery or merely a result of a direct effect of antidepressants remains to be determined.
