W. Katon et al., INFREQUENT PANIC ATTACKS - PSYCHIATRIC COMORBIDITY, PERSONALITY-CHARACTERISTICS AND FUNCTIONAL DISABILITY, Journal of Psychiatric Research, 29(2), 1995, pp. 121-131
Primary care patients with infrequent panic attacks were found to have
similar levels of disability in their social, family and vocational f
unctioning to patients who met DSM-III-R criteria for panic disorder.
Both panic subgroups had significantly more functional disability than
controls. Patients with panic and infrequent panic had significantly
more Axis I psychiatric comorbidity than primary care controls but sim
ilar levels of medical comorbidity. Patients with panic disorder had a
significantly higher prevalence of one or more other lifetime psychia
tric diagnoses, current major depression, and current DSM-III-R depres
sive symptoms compared to patients with infrequent panic, Patients wit
h infrequent panic scored as high on the NEO personality measure of ne
uroticism as patients with panic disorder, and both panic subgroups ha
d significantly higher neuroticism levels than controls.
