Prostaglandins are thought to act as neuromodulators of both central catecholamine and endocrine systems. Abnormalities of these systems have been described in affective disorders, in general, and in agoraphobia with panic attacks, in particular. This study measured basal prostaglandin-E (PGE) cerebrospinal fluid (CSF) levels in 20 patients with agoraphobia with panic attacks and 10 nonpsychiatric controls. In a subgroup of patients and controls, CSF levels of adrenocorticotrophic hormone (ACTH) and corticotropin-releasing factor (CRF) were also measured. There was no significant difference in CSF PGE levels between patients and controls. However, patients with higher depression scores had lower CSF PGE levels. CSF PGE levels tended to correlate with CSF ACTH, but not CSF CRF in the patient group, in general, and in the female patients, in particular. These findings do not support an abnormality in basal CNS PGE production in agoraphobia with panic attacks, but suggest further study of the PGE modulatory effect on the hypothalamic-pituitary-adrenal axis in this disorder.

A naturalistic study with no predetermined duration of treatment was undertaken in order to examine the effectiveness of cognitive therapy in the treatment of panic disorder. Seventeen patients diagnosed as having panic disorder according to the Structured Clinical Interview for DSM-III Personality Disorders received a mean of 18 individual cognitive therapy sessions. Patients with personality disorder or depression required a longer duration of treatment to become symptom-free. As measured by a self-report weekly panic log, the mean number of panic attacks was reduced significantly to zero at the end of treatment. There was a concomitant reduction in self-report measures of depression and anxiety. Further, there was a significant reduction on a measure of cognitive dysfunction during panic attacks. Treatment results were maintained at 12-month follow-up.

A cause-and-effect relation between panic attacks and agoraphobia is an accepted concept. It is believed that, left unchecked, a subgroup of patients with panic attacks will consistently develop agoraphobia. However, to date, there are no means for early identification of this at-risk group. This study analyzed patients with panic attacks and phobic avoidance behaviors by using population-based, survey-collected data. Path analysis was used to determine relations among panic symptoms, phobic behaviors, panic-phobic lag times, and measures of pervasiveness and severity of fears and panic. Panic-related chest pain, dyspnea, trembling, and fear were important factors in the development, pervasiveness, and severity of situational fears and anticipatory anxiety. However, full-blown agoraphobia was only related to the presence of anticipatory anxiety and the pervasiveness of phobic avoidance behaviors. Although the age-of-onset of panic and phobic avoidance was unrelated to other factors, lag times were dependent upon panic symptomatology and the presence of depression. These findings suggest that patients with panic attacks who are at risk for agoraphobia can be identified by the nature of their panic symptoms, and perhaps, through early treatment, the development of phobic avoidance can be averted.

This paper examines the nosological and aetiological relationships of panic disorder to the anxiety states and depression. The phenomenology is detailed from an unbiased sample of 90 cases selected, on the basis of meeting positive criteria for panic disorder, from 3 series of consecutive cases. Panic attacks were found to be only quantitatively distinct from non-panic anxiety. Truly spontaneous attacks, not preceded by anxiety-provoking cognitions, were uncommon. No unique association with agoraphobia was seen, other anxiety states and depression being common. Social phobia and generalized anxiety often preceded the development of panic disorder, as did some cases of agoraphobia. Depression was usually non-specific and secondary when only DSM-III MDE criteria were used. Significant neurotic traits were found, particularly anxiety, dependency and poor sexual adjustment. Panic disorder has multiple causal factors only one of which is a genetic tendency for panic attacks. While important therapeutically, panic attacks should not be given the primary place in diagnosis.

A review of the clinical literature to date has shown that the nature of the relationship between phobic disorders and anxiety states is still unclear. As a wide range of symptoms are shared by patients with all DSM-III anxiety disorder diagnoses, at this stage there is still a need to investigate the latent dimensions which distinguish the anxiety disorder subtypes. In the present study 176 patients with the DSM-III diagnoses of agoraphobia with panic attacks, social phobia, panic disorder and generalized anxiety disorder completed the Fear Survey Schedule, Fear Questionnaire, Hostility and Direction of Hostility Questionnaire, Maudsley Personality Inventory, and the Hamilton Anxiety and Depression Scales. Group membership was significantly predicted by a discriminant analysis which yielded a Fear Questionnaire agoraphobia function and a social phobia function. The results from discriminant analysis suggests that agoraphobia and anxiety states may be closely related. Classification errors were also determined, providing further evidence with which to refute the claim that agoraphobia has "all or none" characteristics.

Fifty-five patients completed a 5-week double-blind study comparing alprazolam, propranolol, and placebo in the treatment of panic disorder and agoraphobia with panic attacks. There was no concomitant behavioral treatment. Patient and therapist rating scales included Sheehan's Panic and Anxiety Attack Scales, the Marks-Sheehan Phobia Scale, the Hamilton Anxiety Scale, the Hamilton Depression Scale, and the Side Effects Checklist. The results generally support the efficacy of alprazolam, but not propranolol, in the treatment of panic disorder and agoraphobia with panic attacks. The significance of the results are discussed, as well as a number of the unique aspects of our procedures and patient population.

Patients who experienced panic attacks, with or without avoidance, were treated for two weeks with either training in controlled breathing or a placebo treatment. Subsequently, both groups received a limited period of conventional anxiety treatments, most commonly in vivo exposure. Patients were subdivided into 'hyperventilators' and 'non-hyperventilators' on the basis of the conventional provocation test. Observer ratings of anxiety showed a greater improvement for the group that received breathing training, but there was no evidence that 'hyperventilators' benefited more from respiratory training than 'non-hyperventilators'. Self-report measures of anxiety, avoidance, and depression/dysphoria showed no difference between treatments. These findings suggest that training in controlled breathing is not of specific benefit for those identified as 'hyperventilators' by the provocation test, but that it may have a non-specific effect in the treatment of patients with panic attacks.

Six self-rated items of interpersonal sensitivity (IPS) were examined in 174 depressed outpatients. These items were "feeling critical of others," "your feelings being easily hurt," "feeling others do not understand you or are unsympathetic," "feeling others are unfriendly," "feeling inferior to others," "feeling shy or uneasy with the opposite sex." The population was grouped into tertiles based on their pretreatment IPS score. High levels of IPS were associated with earlier onset and greater chronicity of depression, higher Hamilton Rating Scale for Depression (HRSD) score, more severe depressed mood, guilt, suicidality, impaired work and interest, retardation, depersonalization, paranoia, and cognitive symptoms of depression. More frequent atypical features were found, e.g., overeating/weight gain, self-pity, phobic avoidance, and panic attacks. Response to a monoamine oxidase (MAO) inhibitor drug increased at higher levels of IPS, while the response to a placebo decreased.

Patients with alcohol dependence commonly experience symptoms of anxiety, depression, and insomnia. It is essential that clinicians recognize and treat anxiety disorders in alcoholic patients. Panic attacks with and without agoraphobia are especially prevalent among alcoholics and their families. Treatments of choice for panic disorder are the monoamine oxidase inhibitors, as well as tricyclic antidepressants and the benzodiazepine alprazolam. Benzodiazepines seem to be effective in controlling two pathophysiologic characteristics of alcohol withdrawal--noradrenergic and hypothalamic-pituitary-adrenocortical overactivity. They also can be used to prevent and treat withdrawal seizures and delirium tremens. They are not indicated for the treatment of alcohol dependence per se.

The advent of more explicit diagnostic criteria and the growing interest in "lifetime" rates of mental disorders has made imperative an accurate determination of time-related diagnostic criteria. We used data from two independent test-retest studies of the Diagnostic Interview Schedule (DIS) and the Composite International Diagnostic Interview (CIDI) to study the reliability of different time-related questions in these fully standardized diagnostic interviews. With two exceptions (anxiety disorders and alcohol-related questions), the test-retest reliability of most time-related questions in both interviews was judged to be satisfactorily high. Furthermore, the validity of time-related questions in the DIS (age at symptom onset, duration and frequency of illness episodes) was examined by comparing them with detailed "consensus" ratings done independently by different clinicians for 207 former psychiatric inpatients. A surprisingly high concordance was found for former psychotic patients except for those still severely disturbed at the follow-up investigation. Some severe restrictions were also found for nonpsychotic disorders with regard to judgment of the age at onset of phobias, panic attacks, and depression. For a more valid assessment of time-related symptom information, the use of specific memory aids is suggested.
