Hyperthyrotrophinaemia during thyroxine replacement therapy

Psychiatric Symptoms due to Thyroid Disease in a Female Adolescent

The hypothalamic-pituitary-thyroid axis is involved in the production of thyroid hormone which is needed to maintain the normal functioning of various organs and systems, including the central nervous system. This study reports a case of hypothyroidism in a fifteen-year-old female adolescent who was attended for psychiatric symptoms. This case reveals the importance of evaluating thyroid function in children and adolescents with neuropsychiatric symptoms.

Hypothyroidism masquerading as depression: the role of noncompliance

Compliance with prescribed medication is an important but complex issue which is incompletely understood. Depression is also a factor that can lead to noncompliance. A 30-year-old lady was seen in the outpatient clinic with complaints of palpitations and tremor. Her medical history revealed a subtotal thyroidectomy for multinodular goiter five years earlier. During a period of depression, she stopped taking levothyroxine for 45 days. Discontinuation of therapy worsened her depression. At her visit, the dosage of levothyroxine was increased, and the symptoms of depression improved. However, increasing the dosage of thyroid supplement resulted in a hyperthyroid state. The role of depression on noncompliance is also discussed.
