Gender differences in panic disorder: findings from the National Comorbidity Survey.

OBJECTIVE: Several epidemiological studies have demonstrated a higher prevalence of panic disorder in women than in men. This study explored whether the prevalence of specific panic symptoms differs by gender. METHOD: National Comorbidity Survey data from 609 respondents who met DSM-III-R criteria for panic disorder or panic attacks were analyzed to test for gender differences across 18 panic symptoms. RESULTS: Among National Comorbidity Survey respondents with panic disorder or panic attacks, female respondents were more likely than male respondents to experience respiration-related difficulties during panic attacks. CONCLUSIONS: Specific symptoms occurring during panic attacks differ by gender. The pathophysiology of these symptom differences may involve gender differences in sensitivity to CO(2) and in the threshold for panic attacks during hypoxic and hypercapnic states.

Physical and sexual abuse history and addiction treatment outcomes.

OBJECTIVE: Prior research on patients with substance use disorders has shown that lifetime physical or sexual abuse is associated with more impaired functioning at treatment intake. The present study sought to determine whether physical or sexual abuse also predicted treatment response (posttreatment outcomes) of individuals with substance use disorders. METHOD: Male (n = 19,989) and female (n = 622) veterans with substance use disorders were assessed with the Addiction Severity Index (ASI) early in treatment and reassessed an average of 12 months later. Treatment outcomes were compared for patients who did and did not report prior physical or sexual abuse in the initial ASI interview. RESULTS: Lifetime physical or sexual abuse predicted worse outcomes in six of seven domains of functioning, after controlling for baseline functioning, psychiatric diagnoses and demographic variables. Although women were more likely than men to report being abused, the effect of abuse on treatment outcomes was similar for both genders. Psychiatric problems at baseline mediated the effect of abuse history on outcomes. Abuse history moderated the effect of treatment intensity (contacts per month) on outcomes: More frequent treatment contacts were more beneficial for abused patients than for nonabused patients. CONCLUSIONS: Individuals with substance use disorders who have a history of physical or sexual abuse may have higher risk for problematic treatment outcomes as a result of greater psychiatric problems, deficits in social support and possible difficulties in establishing treatment alliance. Clinicians may consider increasing the duration and intensity of treatment to temper the negative effects of abuse on later functioning.

Effects of comorbid diagnoses on sleep disturbance in PTSD.

OBJECTIVE: Patients with post-traumatic stress disorder (PTSD) are frequently diagnosed with other psychiatric comorbid conditions. This study tested the hypothesis that PTSD patients suffer a greater proportion of sleep problems according to comorbid diagnoses. METHOD: National Comorbidity Survey (NCS) data from 591 individuals diagnosed with PTSD were analyzed. Revised versions of the Diagnostic Interview Schedule and Composite International Diagnostic Interview were administered to a representative sample of males and females. Groups consisted of patients diagnosed with lifetime PTSD and with current comorbid panic disorder, major depressive disorder, generalized anxiety disorder, and alcohol dependence. RESULTS: Patients diagnosed with PTSD/panic disorder reported a significantly greater proportion of nightmare complaints (96%) and insomnia (100%) compared with the other comorbid groups. CONCLUSIONS: A greater proportion of PTSD patients with comorbid panic disorder complain of sleep-related problems than other comorbid groups. This effect appears unique to panic, rather than other general anxiety disorder or depression. Prospective sleep studies are needed to differentiate the role of sleep in PTSD and PD, as well as to examine the role of psychiatric comorbidity in worsening sleep in PTSD patients.

How well are clinicians following dementia practice guidelines?

Although there are numerous clinical guidelines regarding the management of dementia, there have been few studies on their implementation in practice. Clinicians in six United States Department of Veterans Affairs medical centers (n = 200, 85% response rate) were surveyed regarding their use of practices recommended in the California Workgroup Guidelines for Alzheimer's Disease Management. The majority of providers (89% to 73%) reported that they routinely conducted neurological examinations, obtained histories from caregivers, discussed the diagnosis with the patient's family, discussed durable power of attorney, and made legally-required reports of drivers with dementia. Roughly two-thirds of providers said they routinely conducted cognitive screening examinations, screened for depression, reported elder abuse, and discussed care needs and decision-making issues with patients' families. Only half of all outpatient providers implemented caregiver support practices for at least half of their patients. Clinicians' choices of medications for cognition, mood, and behavior problems were broadly consistent with current practice guidelines. These results suggest possible priorities for quality improvement efforts. Further research is needed to clarify reasons for particular gaps between guidelines and practice and to identify specific targets for intervention.

Aging and panic disorder: phenomenology, comorbidity, and risk factors.

OBJECTIVE: The authors compared young and older adults with panic disorder (PD) to investigate differences in panic-associated phenomenology, psychiatric comorbidity, and risk factors. METHOD: Patients in the older group (age 60 and above) were further subdivided into early- and late-onset groups and compared. Phenomenology (number of panic symptoms, severity of anxiety, physiological symptoms, panic-associated cognitions, and overall severity of PD); comorbidity (depressive and anxiety disorders); and risk factors (family history of anxiety and life stressors) were assessed in 167 outpatients with PD. RESULTS: Older patients reported fewer panic symptoms, less anxiety and arousal, less severe PD, lower levels of depression, and higher levels of functioning. Furthermore, within the older-patient group, late-onset patients were found to report less distress during panic attacks in relation to body sensations and panic-related cognitions and emotions. Multiple-regression analysis of the entire sample showed that chronological age and age at onset of PD distinctly predicted different domains of panic phenomenology. CONCLUSION: PD was consistently less severe in older patients across multiple domains, and a later age at onset was associated with less distress due to body sensations, cognitions, and emotions during panic attacks.
