However, on the contrary there are even more papers supporting the idea of a subclinical thyroid dysfunction, especially in melancholic or refractory patients, possibly of an autoimmune hypothyroidism depression [ 44 - 55 ] suggesting that subclinical hypothyroidism may lower the threshold for the occurrence of depression[ 56 ], or generally to any mental disorder [ 57 - 59 ]. Prevalence of antithyroid antibodies in mood disorders. Journal of Young Investigators. However, its association with depression remains controversial at large, with some studies indicated that SCH had the same propensity with overt hypothyroidism, while the others reported conflicting findings [ 7812 — 24 ]. However, in healthy subjects, supraphysiological T4 doses were less well tolerated due to higher increments in thyroid hormones after supplementation [ 73 ]. Neuropsychiatric aspects of hypothyroidism and treatment reversibility. However, this should be viewed with caution since these reports either lacked a control group [ 424345 ] or showed no significant difference between the group with an affective disorder and the control group with a nonaffective psychiatric disorder [ 44 ].

Then again, evidence of overt or subclinical hypothyroidism, hypothyrojdism raised antibody titres, has often been found among patients with bipolar disorder, prior to treatment with lithium [ 315253 ]. These results suggested that relationships between thyroid and cerebral activity could not only explain HPT axis contributions to the genesis of bipolar disorders, but, could also account for the therapeutic effects of thyroid hormones in bipolar disorders. Results Figure 1 shows the flow of studies selection. Indeed, the actions of thyroid hormones on neurotransmitter systems appear to be more pronounced in neonatal animals [ 2], thus, underlining the important effects of thyroid hormones on formation and organization of neurotransmitter systems in the developing brain [ — ].
