Panic disorder with nocturnal panic attacks: symptoms and comorbidities

Area of Science:

• Psychiatry
• Clinical Psychology
• Sleep Medicine

Background:

• Panic disorder is a significant mental health concern.
• Nocturnal panic attacks (NPAs) are a distinct subtype of panic attacks occurring during sleep.
• Understanding the clinical correlates of NPAs is crucial for effective treatment.

Purpose of the Study:

• To investigate the relationship between nocturnal panic attacks (NPAs) and comorbidities, clinical variables, and specific panic attack symptoms.
• To compare patients with and without NPAs across various psychological and symptomological measures.

Main Methods:

• One hundred and six patients diagnosed with DSM-IV panic disorder were recruited.
• Patients were categorized into two groups: those experiencing NPAs and those without.
• Diagnostic interviews (SCID-I, SCID-II) and psychometric assessments (Beck Depression Inventory, State-Trait Anxiety Inventory, Symptom Checklist) were utilized for comparison.

Main Results:

• Nocturnal panic attacks were not significantly associated with comorbidities or age of disease onset.
• Patients with NPAs reported higher scores on the Beck Depression Inventory, overall Symptom Checklist, and specific subscales (somatization, obsession-compulsion, interpersonal sensitivity, anger-hostility).
• Respiratory symptoms were more frequent in the NPA group, suggesting a potential link between NPAs and respiratory distress during panic episodes.

Conclusions:

• Nocturnal panic attacks are associated with a greater burden of depressive and other psychiatric symptoms compared to non-NPA panic disorder.
• The increased prevalence of respiratory symptoms in NPAs warrants further investigation into their potential role.
• Findings highlight the need for tailored therapeutic approaches for patients experiencing nocturnal panic attacks.
