Psychotic Depression Related to Hashimoto’s Thyroiditis: A Case Report

Abstract

Hashimoto’s thyroiditis can lead to depression, anxiety disorder, and sleep problems. However, this autoimmune disease has been reported to be less related to psychotic depression. The case applied to our outpatient clinic with introversion, anhedonia, and guilt thoughts. The patient was admitted to our clinic with a preliminary diagnosis of psychotic depression. TSH value was found to be high in the patient’s hormone analysis. Afterward, treatment was started with the diagnosis of Hashimoto’s thyroiditis according to the patient’s anti-TPO value and thyroid USG results. After levothyroxine treatment, the patient’s depression scores, TSH, and anti-TPO values decreased.
