Summary
Thyroid function impacts panic disorder. In non-medicated patients, higher thyroid-stimulating hormone (TSH) correlated with severe panic attacks, while higher free thyroxine (T4) correlated with less anxiety.
Area of Science:
- Endocrinology
- Psychiatry
- Clinical Medicine
Background:
- Panic disorder is a significant psychiatric condition.
- Thyroid hormones play a crucial role in regulating mood and anxiety.
- Previous research suggests a link between thyroid dysfunction and anxiety disorders.
Purpose of the Study:
- To investigate the correlation between thyroid function markers and the clinical severity of panic disorder.
- To explore the relationship between thyroid hormones (T3, T4, TSH) and anxiety/panic attack severity in patients with panic disorder.
Main Methods:
- Study included 66 out-patients diagnosed with panic disorder.
- Patients were categorized into medicated (n=41) and non-medicated (n=25) groups.
- Measurements included serum levels of free triiodothyronine (fT3), free thyroxine (fT4), and thyroid-stimulating hormone (TSH).
Main Results:
- Significant correlations were found between thyroid hormone levels and clinical features in non-medicated patients.
- Higher TSH levels were associated with increased severity of current panic attacks.
- Severity of anxiety showed a negative correlation with free thyroxine (fT4) levels.
Conclusions:
- Thyroid function may be associated with the clinical presentation and severity of panic disorder, particularly in non-medicated individuals.
- TSH and fT4 levels may serve as potential biomarkers for panic attack and anxiety severity in panic disorder patients.
