BACKGROUND: A relationship between primary hyperparathyroidism (PHPT) and decreased quality of life has been shown using patient-reported outcome measures, including Pasieka's Parathyroid Assessment of Symptoms, SF-36, and PROMIS. Despite this, there remains a paucity of objectively measured data demonstrating cognitive dysfunction in patients with PHPT. We assessed whether parathyroidectomy resulted in quantifiable cognitive improvement.
METHODS: We examined 59 consecutive patients with PHPT who underwent parathyroidectomy at a single institution between 2019 and 2021. We used BrainCheck, a clinically validated objective measure of neurocognition, to assess pre- and postoperative neurocognitive changes and evaluated associations between BrainCheck scores and parathyroidectomy using the Wilcoxon signed-rank test.
RESULTS: Of the 59 patients with PHPT who underwent parathyroidectomy and rapid cognitive assessment with BrainCheck, 72.9% were female, 49.2% were White, and 30.5% were African American. A total of 44.1% of patients preoperatively showed neurocognitive dysfunction relative to the general population compared to 22% postoperatively, representing an improvement in 53% of the cohort. Postoperative scores for the entire cohort were significantly higher than preoperative scores (Z =2.85, P = .004). This association remained significant when the cohort was stratified by sex, as both males (Z =2.02, P = .044) and females (Z =2.09, P = .037) had a significant increase in scores. Domain sub-analysis demonstrated a significant association between parathyroidectomy and improved executive function (P < .01).
CONCLUSION: Patients with PHPT experience objectively measurable cognitive changes associated with PHPT that can be reversed by parathyroidectomy, with improvements observed as early as 2 weeks after surgery. Further research with a larger cohort is needed to corroborate our findings.
