Panic disorder (PD) patients exhibit lower urinary pH compared to major depressive disorder (MDD) patients and healthy controls. This lower urinary pH in PD patients inversely correlates with anxiety levels.

Area of Science:

  • Biochemistry
  • Psychiatry
  • Urology

Background:

  • Panic disorder (PD) is a significant mental health condition.
  • Understanding the physiological correlates of PD is crucial for diagnosis and treatment.
  • Previous research has not extensively explored urinary pH in PD patients.

Purpose of the Study:

  • To investigate urinary pH levels in drug-free patients diagnosed with panic disorder.
  • To compare urinary pH in PD patients with those diagnosed with major depressive disorder (MDD) and healthy controls (HC).
  • To explore the relationship between urinary pH and anxiety levels in PD patients.

Main Methods:

  • Evaluated urinary pH in 14 PD patients, 8 MDD patients, and 14 HC subjects.
  • All participants met DSM-IV diagnostic criteria and were drug-free.

Related Experiment Videos

  • Correlational analysis was performed between urinary pH and anxiety levels.

    • Main Results:

    • PD patients demonstrated significantly lower urinary pH compared to both MDD patients and HC subjects.
    • Higher levels of anxiety were observed in PD patients.
    • A significant inverse correlation was found between urinary pH and anxiety levels in PD patients.

    Conclusions:

    • Preliminary findings suggest that panic disorder patients have lower urinary pH than MDD patients and healthy controls.
    • Urinary pH may serve as a potential biomarker for anxiety levels in PD.
    • Further research with larger cohorts, including other anxiety disorders and pre/post-treatment assessments, is warranted.
