The author investigated neurotic symptoms of borderline patients by reviewing the clinical charts of twenty-six patients of longer than one year treatment period (8 men, 18 women; 23 patients with DSM III-R borderline personality disorder (BPD), 14 with schizotypal personality disorder (SPD), (11 BPD-SPD overlaps); age at the first contact: mean = 24.3 y. o., SD = 6.7 y. o.; treatment period: mean = 51 months, SD = 35 months). The diagnoses of the comorbid neurotic disorders were obsessive compulsive disorder: 5 cases (19% (BPD: 22%, SPD: 7%)), somatoform disorder: 5 (19% (BPD: 22%, SPD: 21%)), panic disorder: 4 (15% (BPD: 17%, SPD: 14%)), social phobia: 2 (8% (BPD: 9%, SPD: 7%)), dissociative disorder: 2 (8% (BPD: 9%, SPD: 0%)), and generalized anxiety disorder: 1 (4% (BPD: 4%, SPD: 7%)). The neurotic symptoms identified in the charts of the subjects were as follows; symptoms of social phobia: 11 cases (42% (BPD: 43%, SPD: 43%)) including 6 with anthropophobic symptoms (23% (BPD: 26%, SPD: 36%)), obsessive compulsive symptoms and diffuse and floating anxiety: 9 (35% (BPD: 39%, SPD: 38%)), panic attacks: 8 (31% (BPD: 35%, SPD: 36%)), conversion symptoms: 7 (27% (BPD: 30%, SPD: 21%)), dissociative episodes: 6 (23% (BPD: 26%, SPD: 7%)), depersonalization: 5 (19% (BPD: 22%, SPD: 14%)), multiple apprehensive expectations: 4 (15% (BPD: 17%, SPD: 14%)), derealization: 3 (12% (BPD: 13%, SPD: 14%)), hyperventilation attacks: 3 (12% (BPD: 13%, SPD: 7%)), and somatization: 1 (4% (BPD: 4%, SPD: 7%)). In short, 54% (BPD: 61%, SPD: 43%) of the subjects had comorbid neurotic disorders, and 92% (BPD: 91%, SPD: 93%) reported at least one, and 54% (BPD: 61%, SPD: 50%), more than two kinds of neurotic symptoms, though no specific symptom correlating with BPD or SPD diagnosis was found. These findings suggest that neurotic symptoms and neurotic disorders cannot be ignored as peripheral in the borderline symptomatology. By analyzing in detail the neurotic experiences, the author pointed out as their characteristics, ego syntonicity, deterioration of reality sense and symptomatic polymorphism, ambiguity and multiplicity (panneurosis). In the symptoms the author observed signs of defective personality functioning such as disavowal of reality, low anxiety tolerance, various forms of identity disturbances. The findings counted above, suggest that the borderline neurotic symptoms are more severe in nature than those of neurotics, and could be situated in between neurotic and psychotic levels of symptomatic severity. The results indicate that the neurotic experiences of borderline patients are, as a whole, deeply ingrained in the borderline psychopathology.

In order to examine the validity of the distinction between generalized anxiety disorder (GAD) and panic disorder (PD) we compared 41 subjects with GAD and 71 subjects with PD. The GAD subjects had never had panic attacks. In contrast to the symptom profile in PD subjects suggestive of autonomic hyperactivity, GAD subjects had a symptom pattern indicative of central nervous system hyperarousal. Also, subjects with GAD had an earlier, more gradual onset of illness. In terms of coexisting syndromes, GAD subjects more often had simple phobias, whereas PD subjects more commonly reported depersonalization and agoraphobia. GAD subjects more frequently had first-degree relatives with GAD, whereas PD subjects more frequently had relatives with PD. A variety of measures indicated that our GAD subjects had a milder illness than those with PD. Also, fewer GAD subjects gave histories of major depression than did PD subjects. Among GAD subjects, coexisting major depression was associated with simple phobia and thyroid disorders and among PD subjects, comorbid depression was associated with social phobia and hypertension. Our findings indicate that the separation of GAD from PD is a valid one. They also indicate that, within disorders, unique patterns of comorbidity may exist that are important both clinically and theoretically.

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.

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.

This paper reviews anxiety, panic, and phobic disorders as they were described in landmark works, along with more recent epidemiologic studies of the disorders. The author discusses clinical syndromes of anxiety as outlined in the DSM-III: agoraphobia, social phobia, generalized anxiety disorder, panic disorder, simple phobic states, and obsessive-compulsive disorder, relating them to Phobic Anxiety-Depersonalization Syndrome and to earlier descriptions by Westphal and Benedict. The paper addresses the problem of delineating anxiety and phobic states from depressive disorders, with regard to diagnosis and treatment outcome. Various etiological bases of agoraphobia, panic, and anxiety disorders are suggested: heredity, life events and circumstances, family background and developmental history, the premorbid personality, and some psychological aspects. Several questions are explored on the relationships of agoraphobia, anxiety and panic attacks. For example, is agoraphobia a new disease or one stage in the development of severe chronic anxiety? Are the phobias of agoraphobia acquired by conditioning or learning? Are "panics" spontaneous or physiological? Are panic attacks the first event in the primary cause of agoraphobia? For future work the authors propose a reassessment of the prevalence of agoraphobia and related disorders, a more careful definition of the agoraphobic disorders, and thorough clinical investigation of the various treatment modalities in well-defined populations. The past twenty years' achievements in behavioural and pharmacological treatments for agoraphobia are briefly recapitulated.

This paper examines the role of uncontrolled depersonalization associated with marijuana use in the development of agoraphobia. Cases of six people are described, all of whom reported first experiencing depersonalization while using marijuana, and subsequently experiencing depersonalization while not using the drug. A fear of this 'uncontrolled' depersonalization resulted in considerable anticipatory anxiety and panic attacks. Patients ultimately presented for treatment of agoraphobia. A temporal relationship between marijuana use, uncontrolled depersonalization, panic attacks and agoraphobia does not imply causality. Comparison of these cases with other agoraphobia clinic patients provides tentative evidence for a difference between the two types of patients. There were no systematic patterns of stressors in the cases prior to the onset of symptoms. Data obtained before and after treatment indicated the cases were slightly more severe than clinic patients. Males and females were represented equally in the cases, whereas there was a higher incidence of females in the clinic patients. The cases' age of onset was younger than that of the clinic patients. Our standard cognitive-behavioural treatment programme required modification to account for the intensity of the fear of depersonalization in the cases.

The present study evaluated the efficacy of three tasks in inducing depersonalization (DP) and derealization (DR) in three different groups: (a) panic disorder patients who report these symptoms while panicking (PD + DD; n = 10); (b) panic disorder patients never experiencing these symptoms during panic attacks (PD; n = 10); and (c) nonanxious controls (NC; n = 10). Clinical features of the PD+DD and PD Ss were compared as well. Relative to PD Ss, PD + DD Ss evidenced higher levels of depression, trait anxiety, more fear of panic, and had a briefer duration of their disorder. A substantial proportion of NC Ss reported past DP and DR experiences. DP and DR induction procedures were the following: staring at a dot on the wall, staring in a mirror, and silent repetition of one's name. Results indicated two tasks (mirror and dot) successfully elicited these sensations above baseline levels with DP reported more frequently and intensely than DR for all Ss. The PD + DD Ss evidenced greater baseline-to-task increases in DP and DR relative to the other two groups and exhibited a differential fear response, particularly on the dot task, with 30% of these Ss intentionally distracting themselves or terminating the induction.

The patients with panic affections (PA) treated with clomipramine hydrochloride (anafranil) were examined clinically and psychopathologically in relation to the drug response. PA diagnostic category was not uniform and may be subdivided into at least two subgroups, responders and non-responders to clomipramine hydrochloride. The responders had minor symptoms of PA, less severe vegetative impairment, though they were more seriously affected by depersonalization, maniophobia and agoraphobia. In this group the drug induced improvement and reduction of the attack frequency and severity within treatment month 1. Nonresponders had distinct vegetative symptomatology in the absence of agoraphobia. They failed clomipramine hydrochloride treatment as the panic attacks resumed, occasionally even with greater frequency.

Using cluster analysis of 207 patients with panic disorder (PD), we investigated the relationships between several panic symptoms at the time of panic attacks, which included anticipatory anxiety, agoraphobia, and 13 clinical symptoms based on the Diagnostic and Statistics Manual-III-Revised. Cluster analysis revealed three panic symptom clusters: cluster A (dyspnea, choking, sweating, nausea, flushes/chills); cluster B (dizziness, palpitations, trembling or shaking, depersonalization, agoraphobia, and anticipatory anxiety); and cluster C (fear of dying, fear of going crazy, paresthesias, and chest pain or discomfort). Generally, cluster A was comprised exclusively of physiological symptoms, among which respiratory symptoms were prominent, cluster B included both panic and non-panic symptoms such as agoraphobia and anticipatory anxiety, and cluster C was comprised chiefly of fear symptoms.

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.
