Abstract :

Background: Thyroid hormones have, from time immemorial, been known to have an impact mood and cognition. The thyroid hormones affect the neuronal functions at multiple levels– ranging from receptors, neurotransmitter systems, myelination, to intracellular genomic effects. Depression and anxiety are the most common mental conditions seen in thyroid disorders. There is also the possibility that the co–occurrence of psychiatric and thyroid diseases may be a result of shared genetic and biochemical abnormalities. There have been a multitude of studies exploring the quality of life and psychiatric co–morbidity, in patients afflicted with thyroid disorders. Materials and methods: 147 patients with thyroid disorders who attended the outpatient Endocrinology Department at the hospital were evaluated for psychiatric morbidity. We estimated the severity and prevalence of depression and anxiety. We have followed up the patients for a period of six months, while they are receiving treatment for thyroid. We reassessed them for psychiatric morbidity during the follow up period and compared the prevalence rates and severity of depression and anxiety. We also did a correlation between demographic and illness variables with the presence and severity of psychiatric morbidity. Results: Of the 147 participants, 93% were women. The average duration of thyroid dysfunction was 1.76 years. There was a significantly high prevalence of depression (59.2%) and anxiety(21.8%) in thyroid patients initially. After six months the prevalence rates decreased to 41.5% and 7.5% respectively .The psychiatric morbidity decreased significantly when the underlying thyroid dysfunction was corrected, without the use of any psychotropic medications. Conclusion: There is a high prevalence of depression and anxiety in thyroid patients. There is a need for compulsory screening, follow up and review of these patients for psychiatric morbidity. The prevalence and severity depression and anxiety decrease significantly with appropriate and adequate management of the thyroid disorder, without any psychopharmacological intervention.
