The relation between panic disorder and suicidal behavior has been surrounded by perennial controversy. A significant number of reports suggest that PD is associated with suicidal behavior. Alternatively, it has been proposed that comorbid depression may account for the increased suicidality identified in this population. ⋯ In this clinical outpatient sample, the association between panic disorder and suicidal behavior was primarily explained by comorbidity with depressive disorders. No differences were observed between different groups for measures of severity of the suicidal behavior. Physicians should be aware of these associations when assessing adults with panic disorder for suicidality.

Previous research has suggested that chronic pain patients might be particularly vulnerable to the effects of negative mood during information processing. However, there is little evidence for abnormal brain processing of affective and sensory pain-related information in chronic pain. Behavioral and brain responses, to pain descriptors and pleasant words, were examined in chronic pain patients and healthy controls during a self-endorsement task. ⋯ These data support the notion of abnormal information processing in chronic pain patients, which might be characterized by a lack of dissociation between sensory and affective components of pain-related information, and by an exaggerated rumination over word meaning during the encoding of self-referent information about pain.
