Panic Disorder (PD) patients consume significantly more caffeine than healthy individuals, with some engaging in harmful use. Chronic caffeine intake may be linked to tolerance rather than panic symptom severity.
Area of Science:
- Psychiatry
- Clinical Psychology
- Neuroscience
Background:
- Acute caffeine intake triggers panic attacks in most Panic Disorder (PD) patients.
- Limited understanding exists regarding chronic caffeine consumption patterns in PD patients.
Purpose of the Study:
- To evaluate caffeine usage in individuals diagnosed with Panic Disorder.
- To determine associations between caffeine consumption and sociodemographic or clinical characteristics in PD patients.
Main Methods:
- A comparative study involving 65 adults with PD and 66 healthy controls.
- Quantification of weekly caffeine intake using a questionnaire.
- Analysis of correlations between caffeine consumption and demographic/clinical factors, defining harmful use as >400 mg/day.
Main Results:
- PD patients exhibited significantly higher caffeine consumption than controls (P < 0.001).
- 14% of PD patients engaged in harmful caffeine use; 40% used caffeine-containing medications.
- PD patients consumed energy drinks more frequently than controls and reported less sleep (P < 0.001).
- No correlation was found between caffeine intake and panic attack frequency, depression comorbidity, or sedative medication use in PD patients.
Conclusions:
- Elevated caffeine consumption in PD patients may stem from developing tolerance to regular use.
- The existence of caffeine-sensitive and non-sensitive PD patient subtypes could explain varying tolerance levels.
