An absent TSH nocturnal surge [ 48 ] has been noted in depression and a lower basal TSH has been reported in major depression as opposed to nonmajor depression [ 49 ]. Surprisingly, T4 in high doses was well tolerated even in patients treated for up to 51 months. Two reviewers conducted this step independently and disagreements were resolved by consensus. Subclinical hypothyroidism SCH is not associated with metabolic derangement, cognitive impairment, depression or poor quality of life QoL in elderly subjects.

Journal of Nuclear Medicine. The authors conclusively found that there was no association between the depression of subclinical hypothyroidism and the development of depression during a mean follow-up of 2 years by the CES-D cutoff of 16 in this large cohort. The effects of T3 acceleration appeared to be more remarkable as the percentage of women in a trial increased therefore suggesting that women might benefit more than men from T3 supplementation [ 67 ].

One preeminent hypothesis to explain the above finding is that chronic TRH hypersecretion associated with depression leads to downregulation of pituitary TRH receptors [ 24535556 ]. Neuropsychiatric Manifestations of Thyroid Disorders Primary thyroid disorders including both hypothyroidism and hyperthyroidism may be accompanied by various neuropsychiatric manifestations ranging from mild depression and anxiety to overt psychosis.

In addition to these sensitivity analyses, there are a number of other strengths to this study, particularly the large sample size, as this is by far the largest such study to date.

In this theory, depression is a state of local hypothyroidism in the brain with normal peripheral thyroid hormone level as a result of deiodinase type II inhibition and impaired transport trfated T4 across the blood-brain barrier [ 10 ].

Introduction

On the other hand, hypothyroid patients frequently demonstrate features of depression, cognitive dysfunction, apathy, and psychomotor slowing. But the research is conflicting as to how strong this connection is. These small-scale tsh levels in treated hypothyroidism and depression well-conducted studies provide additional evidence that subclinical hypothyroidism and depression are not causally linked. Corroborating this clinical impression, a recent report from the United Kingdom showed that L-T4 is being prescribed more frequently and for more mild degrees of hypothyroidism 2. Some studies reported that the prevalence of depression is higher in persons with SCH than in euthyroid people, 47 while others found the risk for depression is comparable between the two population 68.
