Derealization and panic attacks: a clinical evaluation on 150 patients with panic disorder/agoraphobia.

One hundred fifty patients with Panic Disorder (PD) with or without Phobic Avoidance were subdivided into two groups on the basis of presence/absence of derealization and/or depersonalization (D-D) during panic attacks. D-D was found in 34.7% of the sample. By comparing the two groups, the patients with D-D were found to be younger and had an earlier onset of the disorder; they had a higher prevalence of avoidance behavior and a higher severity of the agoraphobic spectrum phobias. They were also more frequently subject to concomitant disorders such as Generalized Anxiety, Obsessive-Compulsive, and depressive symptomatology. The authors have hypothesized a correlation between the presence of D-D during panic attacks and a more frequent clinical evolution toward agoraphobia. This view is supported by finding that D-D in panic attacks corresponds to severer forms of PD, both in terms of the earlier onset of PD, and because PD shows higher levels of anxiety, depression, and disability.

Primary and secondary social phobia: psychopathologic and familial differentiations.

We compared "primary" social phobic patients (n = 25) with patients whose social phobia developing in the setting of panic disorder ("secondary" social phobics, n = 26) and panic-agoraphobic patients (n = 82). Familial, demographic, and symptomatologic data suggest a categorical distinction between the two types of social phobia. Secondary social phobics were essentially similar in all parameters to panic disorder with agoraphobia. These data support DSM-III conventions.

Impairment of work and leisure in depressed outpatients. A preliminary communication.

In a detailed analysis of the effects of depression on a broad range of social, marital, vocational adjustment and leisure time activities in 176 outpatients with mild to moderate depressions, major disturbances were seen in all areas of functioning. These disturbances were most pronounced in the areas of work and social leisure. Except for continued impairment in leisure, these disturbances were considerably attenuated in those patients who were at a mild or asymptomatic level of depression at the time of comparison. These data suggest that functions which depend on traditional roles in family or at work tend to oscillate with the level of depression, whereas functions that require personal initiative (e.g. leisure) may remain abnormal well into the interepisodic phase. The reported disturbances were especially marked in dysthymic or chronic depressives who seem to suffer from the long-term effects of depression.

Differential changes in areas of social adjustment from depressive episodes through recovery.

The findings of the present short-term prospective study of 99 depressed outpatients further support previous cross-sectional observations to the effect that the course of depressive illness is often complicated by fluctuating social disturbances manifested by uneasiness in the work area, by disagreements with colleagues, and by difficulty in maintaining conflict-free relationships with significant others. By contrast, the incapacity to enjoy and use leisure time appeared less related to the symptomatologic variation in depression. Although we favor the hypothesis that impairment in leisure activity may represent a trait marker of depression, the hypothesis of it being a residual complication of repeated depressive episodes cannot be ruled out in view of short follow-up.

Clomipramine for panic disorder: I. The first 10 weeks of a long-term comparison with imipramine.

Clomipramine and imipramine treatments were compared in a sample of 152 panic disorders. Diagnosis was according to the positive criteria of DSM-III-R, but without exclusion of comorbid affective or personality disorders. The 2-year design provides non-blind treatment under typical clinical practice conditions, and it includes random assignment, periodic assessment with standardized measures, and comparable, flexible drug dosages. Findings on six outcome measures in the first 59 cases to complete 10 weeks showed both tricyclics to be markedly and equally effective for blocking panic attacks, alleviating phobic avoidance, and reducing nonspecific aspects of anxiety. Clomipramine's predominantly serotonergic action seemed not to determine a different action spectrum. During the first 2 weeks, clomipramine was significantly and unexpectedly superior to imipramine in both antipanic and antiphobic actions. These results require replication under double-blind conditions.

Polarity of the first episode, clinical characteristics, and course of manic depressive illness: a systematic retrospective investigation of 320 bipolar I patients.

In 320 patients with established bipolar I disorder, we examined the past course on the basis of polarity at onset (depressive, mixed, and manic). Despite the obvious limitations of retrospective methodology, information on course parameters in a large sample of affective disorders is most practically obtained by such methodology. We believe that our systematic interview of patients and their relatives--as well as the systematic study of their records--minimized potential biases. Depressive onsets were the most common, accounting for 50%, followed by mixed and manic onsets in about equal proportion. In general, the polarity of episodes over time reflected polarity at onset. Those with depressive onset had significantly higher levels of rapid cycling, as well as suicide attempts, but were significantly less likely to develop psychotic symptoms. Mixed onsets, too, had high rates of suicide attempts, but differed from depressive onsets in having significantly more chronicity yet negligible rates of rapid cycling at follow-up evaluation. Because cases with depressive onset had received significantly higher rates of psychopharmacologic treatment, our data are compatible with the hypothesis that antidepressants may play a role in the induction of rapid cycling. Overall, our data support the existence of distinct longitudinal patterns within bipolar I disorder, which in turn appear correlated with the polarity at onset. In particular, rapid cycling and mixed states emerge as distinct psychopathologic processes.

Psychosensorial and related phenomena in panic disorder and in temporal lobe epilepsy.

Since Cullen coined the term "neurosis" in the 18th century, medical investigators have searched the neural substrates of conditions we now classify as anxiety disorders. Harper and Roth in 1962 hypothesized that the temporal lobes might represent one such substrate for phobic-anxious patients with depersonalization-derealization (DD); the association between the presumed temporal lobe feature and phobic anxiety was so compelling that Roth (in 1959) described the condition as "phobic-anxiety-depersonalization" syndrome. Introduced into our current nosology as panic disorder-agoraphobia (PDA), this seemingly neuropsychiatric condition is nonetheless distinct from complex partial epilepsy (CPE), from which it is conventionally differentiated through clinical and anamnestic evaluation. Yet increasingly there are clinical-and laboratory-hints of certain overlap between manifestations of the two disorders, hitherto based largely on evaluation of psychosensorial phenomena in PDA or affective phenomena in CPE. We located only one systematic study that monitored 24-hour electroencephalogram (EEG) abnormalities in PDA. Finally, recent epidemiologic data suggest a significantly greater than chance association between PDA and a history of seizures. To further explore these intriguing links, the present study directly compared a group of 91 PDA outpatients with a group of 41 CPE outpatients with respect to DD and other psychosensorial symptoms. The broad similarities discovered between psychosensorial and related phenomena provide further support for the hypothesis that there may be a common neurophysiological substrate linking CPE phenomena with PDA.

Hypochondriasis and illness phobia in panic-agoraphobic patients.

In a sample of 131 patients with panic disorder, we explored both the presence of DSM-III-R criteria for hypochondriasis and the occurrence of illness phobia before the onset of panic disorder. To explore further the possible relationship between hypochondriacal features and panic-agoraphobic syndrome, we compared patients both with and without current hypochondriasis and then patients both with and without illness phobia before the onset of panic disorder. Finally, we investigated the relationship between premorbid phobic-anxious traits and hypochondriasis during panic disorder. No differences were found between patients with and without hypochondriasis, either in terms of clinical features or in the course of panic disorder. Patients with illness phobia before the onset of panic disorder reported higher levels of anticipatory anxiety in nonagoraphobic situations and more depersonalization and derealization during panic attacks, and they met our definition of phobic-anxious temperament more frequently than the rest of the sample. This would suggest that illness phobia before the onset of panic disorder may be viewed either as a separate disorder, a prodrome, or a mild, early-onset form of panic disorder without full-blown attacks. Although patients with premorbid illness phobia are more likely to develop hypochondriasis after the onset of panic disorder, approximately 40% of them do not; therefore, illness phobia should not be considered the only factor that influences the development of hypochondriasis during panic disorder.

The high prevalence of "soft" bipolar (II) features in atypical depression.

Seventy-two percent of 86 major depressive patients with atypical features as defined by the DSM-IV and evaluated systematically were found to meet our criteria for bipolar II and related "soft" bipolar disorders; nearly 60% had antecedent cyclothymic or hyperthymic temperaments. The family history for bipolar disorder validated these clinical findings. Even if we limit the diagnosis of bipolar II to the official DSM-IV threshold of 4 days of hypomania, 32.6% of atypical depressives in our sample would meet this conservative threshold, a rate that is three times higher than the estimates of bipolarity among atypical depressives in the literature. By definition, mood reactivity was present in all patients, while interpersonal sensitivity occurred in 94%. Lifetime comorbidity rates were as follows: social phobia 30%, body dysmorphic disorder 42%, obsessive-compulsive disorder 20%, and panic disorder (agoraphobia) 64%. Both cluster A (anxious personality) and cluster B (e.g., borderline and histrionic) personality disorders were highly prevalent. These data suggest that the "atypicality" of depression is favored by affective temperamental dysregulation and anxiety comorbidity, clinically manifesting in a mood disorder subtype that is preponderantly in the realm of bipolar II. In the present sample, only 28% were strictly unipolar and characterized by avoidant and social phobic features, without histrionic traits.

Depressive comorbidity of panic, social phobic, and obsessive-compulsive disorders re-examined: is there a bipolar II connection?

Utilizing the DSM-III-R schema, we have investigated lifetime comorbidity between panic disorder with or without agoraphobia (PD), social phobia (SP) and obsessive-compulsive disorder (OCD) on the one hand, and mood disorder on the other. Compared with PD, the results for SP and OCD showed significantly higher numbers of comorbid anxiety and mood disorders. In addition, SP and OCD were significantly more likely to cooccur with each other than with PD. The complexity of these comorbid patterns is underscored by the finding of significantly higher numbers of anxiety disorders in those with lifetime comorbidity with bipolar (especially bipolar II) disorder. We conclude that the comorbidity between anxiety and mood disorders - conventionally conceived as the relationship between anxiety and unipolar depressive states -- might very well extend into the domain of bipolar spectrum disorders in a subset of these disorders. Among the latter, the spontaneous or antidepressant-induced switches into brief disinhibited (hypomanic) behavior can be conceptualized to lie on a dimensional continuum with the temperamental inhibition (or constraint) underlying the anxiety disorders under discussion. These findings and theoretical considerations have important therapeutic implications.

Bipolar II and unipolar comorbidity in 153 outpatients with social phobia.

Previous studies on social phobia (SP) have focused largely on comorbidity between SP and major depression. Less attention has been devoted to the comorbidity between SP and bipolar disorder. In this retrospective study, we investigated family history, lifetime comorbidity, and demographic and clinical characteristics among 153 outpatients who met DSM-III-R diagnostic criteria for SP. Information regarding axis I diagnoses was obtained using the Structured Clinical Interview for DSM III-R (SCID-UP-R). Social phobic symptoms and the severity of the illness were assessed by the Liebowitz Social Anxiety Scale (LSAS) and the Liebowitz Social Phobic Disorders Rating Scale, Severity (LSPDRS). Patients completed the Hopkins Symptom Checklist (HSCL 90). Fourteen patients (9.1%) satisfied DSM-III-R criteria for lifetime bipolar disorder not otherwise specified (NOS) (bipolar II), while 71 (46.4%) had unipolar major depression and 68 (44.4%) had no lifetime history of major mood disorders. Comorbid panic disorder/agoraphobia (PDA), obsessive-compulsive disorder (OCD), and alcohol abuse were reported more frequently in the bipolar group than in the other two subgroups. Unipolar patients showed higher rates of comordid PDA and OCD compared with SP patients without mood disorders. Severity and generalization of the SP symptoms, prevalent interactional anxiety, multiple comorbidity, and alcohol abuse appeared to be the most relevant consequences of SP-bipolar coexistence. In a significant minority of cases, protracted social anxiety may hypothetically have represented, along with inhibited depression, the dimensional opposite of gregarious hypomania.
