A control group of 23 subjects was recruited simultaneously from consecutive patients undergoing diagnostic hemithyroidectomy (HT) for benign thyroid nodules. Operations were performed by a single surgeon. Biochemical investigations and neuropsychological symptoms were measured preoperatively and 3\u2003months after surgery. Neuropsychological symptoms were measured using the Hospital Anxiety (HAD\u2010A) and Depression (HAD\u2010D) scales and the Mood Rating Scale (MRS).<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> Postoperatively, calcium and parathyroid hormone normalized in all patients in the pHPT group.
