This study monitored hormone levels in a woman with anxiety disorders before and during a panic attack. Elevated cortisol secretion was observed, suggesting a link between anxiety, depression, and hormonal changes.

Area of Science:

  • Neuroendocrinology
  • Psychiatry
  • Pharmacology

Background:

  • Investigating hormonal correlates of anxiety and panic disorders.
  • Examining the effects of dl-fenfluramine on neuroendocrine function.
  • Assessing serotonergic system involvement in mood and anxiety disorders.

Observation:

  • Hormone secretion curves for prolactin, cortisol, thyroid-stimulating hormone (TSH), and growth hormone (GH) were measured.
  • Measurements were taken in a 37-year-old woman with dysthymia and panic disorder with agoraphobia.
  • Data collected one day prior to (Day I) and during a panic attack (Day II) after oral administration of 60 mg dl-fenfluramine.

Findings:

  • Increased cortisol secretion was observed during the panic attack.
  • The study discusses hormonal correlates of anxiety, including the role of depression.

  • Potential influence of dl-fenfluramine and serotonergic receptor sensitivity on hormonal response.

    • Implications:

    • Provides insight into the neuroendocrine mechanisms underlying anxiety and panic attacks.
    • Highlights the complex interplay between mood disorders, medication, and hormonal regulation.
    • Suggests further research into serotonergic pathways and their modulation in anxiety treatment.
