Parathyroid Dysfunction in Anxiety Disorders
Introduction to Parathyroid Dysfunction
- Significant comorbidity exists between anxiety disorders and thyroid disorders, with nearly all studies finding this association significant, according to the American Psychiatric Association 1
- Hyperthyroidism frequently produces anxiety symptoms including nervousness, palpitations, and increased perspiration that overlap with panic disorder, as noted by the National Institute of Mental Health 1
- Patients with generalized anxiety disorder show 10.4% prevalence of thyroid disorders, higher than the general population, as reported by the Anxiety and Depression Association of America 4
- Subclinical thyroid dysfunction demonstrates a negative association between TSH levels and self-reported anxiety in large population samples, according to the Endocrine Society 6
Parathyroid Dysfunction Screening
- Anxiety symptoms can be a manifestation of parathyroid dysfunction, and screening for parathyroid function is recommended in patients with treatment-resistant anxiety or atypical symptom clusters, as suggested by the American College of Endocrinology 6
- The initial screening should include serum calcium concentration, serum phosphate, and serum magnesium levels, as recommended by the National Academy of Clinical Biochemistry 8
Diagnostic Approach
- If divalent cation abnormalities are confirmed, measure parathyroid hormone (PTH) levels and assess for end-organ complications, as recommended by the American Association of Clinical Endocrinologists 8
- Psychiatric evaluations should include serum calcium concentration testing, which is essential in reassessing patients poorly responsive to mental illness treatment, according to the American Psychiatric Association 8
Quality of Life Implications
- The impact on morbidity and quality of life is substantial, with hypoparathyroid patients on standard treatment showing significantly impaired well-being with predominant anxiety and phobic anxiety symptoms, as reported by the National Institute of Mental Health 8
- Failure to recognize parathyroid disorders leaves endocrine-induced mental dysfunction without proper treatment, perpetuating unnecessary suffering, as noted by the Endocrine Society 8
