Abstract
SummarySeventy one agoraphobie patients with panic attacks, and 54 social phobics, diagnosed according to DSM III criteria have been compared. The two groups were balanced for age, sex, and educational level. Statistical comparisons of clinical, and psychometric variables differentiated the two groups. Panic attacks frequency characterized the agoraphobie patients, while very low assertion scores on Radius’ Assertiveness Schedule characterized social phobies. An association with simple phobias was more frequently found in agoraphobic patients. Comparable levels of generalized anxiety and avoidance were found in the two groups. MMPI mean profile was more disturbed in social phobics. Psychasthenia scale, and anxiety index, were significantly higher in social phobics. Social phobias started earlier, but these patients sought treatment later, and took less psychotropic medication. There was no correlation between assertiveness and panic attacks frequency in the two sub-samples. Principal components analysis of MMPI scales and Assertiveness Schedule confirmed the heterogeneity of the two syndromes. Results are discussed in regard of the extensive use of panic attacks as a general model of anxiety.

Abstract
BACKGROUND Cigarette smoking may increase the likelihood of developing panic disorder. Periods of nicotine withdrawal, in particular, may promote panic in individuals high in anxiety sensitivity. We examined the importance of nicotine withdrawal in the occurrence of smoking and panic. METHODS We utilized a placebo-controlled, double-blind, randomized, crossover design. Fifty smokers underwent a breath-holding (BH) challenge after the transdermal administration of nicotine on one test day and a placebo on another test day. Physiological and psychological variables were assessed at baseline as well as directly before and after the challenges. RESULTS Nicotine abstinence induced a decrease in heart rate and systolic blood pressure (BP) before the BH procedure (heart rate: 78.80 ± 11.43 under nicotine, 70.88 ± 10.83 under placebo; systolic BP: 124.90 ± 11.34 under nicotine, 121.18 ± 13.44 under placebo) and shorter BH duration relative to the nicotine patch condition. Nicotine abstinence did not, though, increase fear reactivity to the challenge. CONCLUSIONS The findings for heart rate and BP are consistent with the stimulant properties of nicotine. The reduced capacity to maintain apnea under placebo might be due to carbon dioxide (CO2 ) hypersensitivity during periods of nicotine abstinence. The negative findings regarding fear reactivity might be due to BH being a relatively weak anxiogen. Future researchers are encouraged to employ CO2 -inhalation procedures to study the relationship between nicotine withdrawal and panic.

Abstract
BACKGROUND The staging method, whereby a disorder is characterized according to its seriousness, extension, development and features, is attracting increasing attention in clinical psychology and psychiatry. The aim of this systematic review was to critically summarize the tools that are available for reproducing and standardizing the clinical intuitions that are involved in a staging formulation. METHODS A comprehensive research was conducted on the MEDLINE, PsycINFO, EMBASE and Cochrane databases from inception to May 2012. The following search terms were used: 'stage/staging' AND 'psychiatric disorder/mental disorder/schizophrenia/mood disorder/anxiety disorder/substance use disorder/eating disorder'. RESULTS A total of 78 studies were identified for inclusion in the review. We discussed studies addressing or related to the issue of staging in a number of mental disorders (schizophrenia, unipolar depression, bipolar disorder, panic disorder, substance use disorders, anorexia and bulimia nervosa). The literature indicates that disorders have a longitudinal development or a treatment history that can be categorized according to stages. We proposed staging formulations for the above-mentioned psychiatric disorders. CONCLUSION Staging models offer innovative assessment tools for clinical psychologists and psychiatrists. Characterizing each stage of an illness demarcates major prognostic and therapeutic differences among patients who otherwise seem to be deceptively similar since they share the same psychiatric diagnosis. A stage 0 to denote an at-risk condition does not appear to be warranted at the current state of research.

Abstract
BACKGROUND Clinical evidence has long suggested there may be heterogeneity in the patterns and predictors of common mood and anxiety disorders; however, epidemiologic studies have generally treated these outcomes as homogenous entities. The objective of this study was to systematically review the epidemiologic evidence for potential patterns of heterogeneity of common mood and anxiety disorders over the lifecourse in the general population. METHODS We reviewed epidemiologic studies examining heterogeneity in either the nature of symptoms experienced ("symptom syndromes") or in patterns of symptoms over time ("symptom trajectories"). To be included, studies of syndromes were required to identify distinct symptom subtypes, and studies of trajectories were required to identify distinct longitudinal patterns of symptoms in at least three waves of follow-up. Studies based on clinical or patient populations were excluded. RESULTS While research in this field is in its infancy, we found growing evidence that, not only can mood and anxiety disorders be differentiated by symptom syndromes and trajectories, but that the factors associated with these disorders may vary between these subtypes. Whether this reflects a causal pathway, where genetic or environmental factors influence the nature of the symptom or trajectory subtype experienced by an individual, or whether individuals with different subtypes differed in their susceptibility to different environmental factors, could not be determined. Few studies addressed issues of comorbidity or transitions in symptoms between common disorders. CONCLUSION Understanding the diversity of these conditions may help us identify preventable factors that are only associated with some subtypes of these common disorders.

Abstract
Agoraphobia with panic disorder is a phobic-anxious syndrome where patients avoid situations or places in which they fear being embarrassed, or being unable to escape or get help if a panic attack occurs. During the last half-century, agoraphobia has been thought of as being closely linked to the recurring panic attack syndrome, so much so that in most cases it appears to be the typical development or complication of panic disorder. Despite the high prevalence of agoraphobia with panic disorder in patients in primary-care settings, the condition is frequently under-recognised and under-treated by medical providers. Antidepressants have been demonstrated to be effective in preventing panic attacks, and in improving anticipatory anxiety and avoidance behaviour. These drugs are also effective in the treatment of the frequently coexisting depressive symptomatology. Among antidepressant agents, SSRIs are generally well tolerated and effective for both anxious and depressive symptomatology, and these compounds should be considered the first choice for short-, medium- and long-term pharmacological treatment of agoraphobia with panic disorder. The few comparative studies conducted to date with various SSRIs reported no significant differences in terms of efficacy; however, the SSRIs that are less liable to produce withdrawal symptoms after abrupt discontinuation should be considered the treatments of first choice for long-term prophylaxis. Venlafaxine is not sufficiently studied in the long-term treatment of panic disorder, while TCAs may be considered as a second choice of treatment when patients do not seem to respond to or tolerate SSRIs. High-potency benzodiazepines have been shown to display a rapid onset of anti-anxiety effect, having beneficial effects during the first few days of treatment, and are therefore useful options for short-term treatment; however, these drugs are not first-choice medications in the medium and long term because of the frequent development of tolerance and dependence phenomena. Cognitive-behavioural therapy is the best studied non-pharmacological approach and can be applied to many patients, depending on its availability.

Abstract
BACKGROUND Embarrassment is emphasized, yet scantily described as a factor in extreme dental anxiety or phobia. Present study aimed to describe details of social aspects of anxiety in dental situations, especially focusing on embarrassment phenomena. METHODS Subjects (Ss) were consecutive specialist clinic patients, 16 men, 14 women, 20-65 yr, who avoided treatment mean 12.7 yr due to anxiety. Electronic patient records and transcribed initial assessment and exit interviews were analyzed using QSR"N4" software to aid in exploring contexts related to social aspects of dental anxiety and embarrassment phenomena. Qualitative findings were co-validated with tests of association between embarrassment intensity ratings, years of treatment avoidance, and mouth-hiding behavioral ratings. RESULTS Embarrassment was a complaint in all but three cases. Chief complaints in the sample: 30% had fear of pain; 47% cited powerlessness in relation to dental social situations, some specific to embarrassment and 23% named co-morbid psychosocial dysfunction due to effects of sexual abuse, general anxiety, gagging, fainting or panic attacks. Intense embarrassment was manifested in both clinical and non-clinical situations due to poor dental status or perceived neglect, often (n = 9) with fear of negative social evaluation as chief complaint. These nine cases were qualitatively different from other cases with chief complaints of social powerlessness associated with conditioned distrust of dentists and their negative behaviors. The majority of embarrassed Ss to some degree inhibited smiling/laughing by hiding with lips, hands or changed head position. Secrecy, taboo-thinking, and mouth-hiding were associated with intense embarrassment. Especially after many years of avoidance, embarrassment phenomena lead to feelings of self-punishment, poor self-image/esteem and in some cases personality changes in a vicious circle of anxiety and avoidance. Embarrassment intensity ratings were positively correlated with years of avoidance and degree of mouth-hiding behaviors. CONCLUSIONS Embarrassment is a complex dental anxiety manifestation with qualitative differences by complaint characteristics and perceived intensity. Some cases exhibited manifestations similar to psychiatric criteria for social anxiety disorder as chief complaint, while most manifested embarrassment as a side effect.

Abstract
It was proposed that pre-post regression slopes be used to index treatment response when the effect of baseline scores differed among treatments (interaction between treatment and baseline score). Reanalyses of two studies using imipramine and fluoxetine in panic disorder showed doserelated decreases in pre-post slopes for the frequency of unexpected panic attacks, but not for the frequency of situational panic attacks or measures of agoraphobia. This report presents similar analyses of data from a study using moclobemide. Patients (N = 452) with panic disorder were randomized to placebo or a fixed dose of moclobemide (75, 150, 300, 600, or 900 mg/day). They were treated double-blindly and evaluated at baseline and 1, 2, 3, 4, 6, and 8 weeks later. The authors analyzed the frequency of unexpected and situational panic attacks compiled from a daily diary, and fear and avoidance ratings based on the patient's main phobia using baseline (pre) and end-point (post) values for all randomized patients. Adjoining dose groups were combined. Both unexpected and situational panic attacks showed systematic doserelated suppression of pre-post treatment slopes. Neither pre-post slopes nor adjusted posttreatment means for fear and avoidance differed reliably between treatment arms. This study replicates the authors' earlier findings, except for situational panic attacks, which probably were not reliably identified. Antidepressants selectively suppress panic attacks, especially unexpected attacks, but not agoraphobia. The findings are consistent with the hypothesis that panic disorder with agoraphobia has clinically separable biologic and cognitive components that respond differentially to treatment. Antidepressants benefit primarily patients with many unexpected panic attacks. Investigators should evaluate pre-post treatment slopes before comparing adjusted posttreatment means (analysis of covariance).

Abstract
Previous studies of autonomic nervous system (ANS) function in panic disorder (PD) patients have yielded conflicting results. We speculate that these differences might result from the variety of clinical stages of PD. In order to investigate this, we compared ANS activity in untreated patients in the early stage of PD with control subjects using power spectral analysis of electrocardiogram R-R intervals (PSR-R) in supine rest and during head-up tilt, which was performed according to the maximum entropy method (MEM). It recognizes two main components: high-frequency power (HF), which mainly reflects cardiac parasympathetic activity, and low-frequency power (LF), which reflects both cardiac sympathetic and parasympathetic activity. The patients with PD had significantly higher values for all components of PSR-R only in tilt position total power (TP), LF, and HF than did the control subjects (P<0.01, <0.01, <0.02, respectively). However, the LF/HF ratio which indicated sympathovagal balance did not differ significantly between the two groups in tilt position. Our findings suggest that patients with PD in the early stage of illness have co-activation of sympathetic and parasympathetic nervous systems, which might act to maintain a balance between the two autonomic systems.

Abstract
The purpose of this study was to identify factors that are associated with expectation of panic attacks as well as to validate the hypothesized tendency to identify false (panic) alarms in panic disorder. Ten women with panic disorder were assessed naturalistically using computer-assisted self-monitoring. This allowed for prospective assessment of expected versus unexpected panic attacks. Expectation of panic attacks was associated with panic occurrence, as well as elevated sense of threat or danger, anxiety, helplessness, avoidance, distress about physical symptoms, physical sensations, and catastrophic thoughts prior to the attack. In general, the state measured prior to unexpected attacks did not differ from ongoing nonpanic state. Furthermore, none of the variables measured during the attacks were able to distinguish unexpected attacks from expected attacks.

Abstract
This study aimed to use a population-based sample to assess the psychological validity of the Seattle system for diagnosing dentally anxious individuals. This system consists of four diagnostic types in which such individuals are categorized according to the main source of their fear regarding dental treatment. Subjects were 1420 randomly selected adults aged 18 years and over who took part in a two-stage mail survey. The questionnaires contained measures of dental anxiety and standardized measures of general anxiety and fearfulness. Allocation to the Seattle categories was based on responses to four diagnostic items. Overall, 16.4% of the sample were dentally anxious. Their distribution across the four Seattle types was as follows: type I (simple conditioned phobia)--49.6%; type II (fear of catastrophe)--7.8%; type III (generalized anxiety)--19.4% and type IV (distrust of dentists)--9.9%. The remaining 13.3% could not be categorized. Judging by their scores on measures of dental anxiety, these subjects were borderline cases. Scores on the measures of anxiety and fearfulness indicated that the diagnostic system was valid and identified sub-groups of the dentally anxious population which were internally consistent. However, all subjects indicated extreme fear of dental treatment and were broadly similar in terms of their cognitive and behavioral responses to dental care. Of particular interest was the distribution of diagnoses according to age. Younger subjects were more likely to be categorized as type I, while older subjects were more likely to be categorized as type III. Overall, the results indicate that dental anxiety is a complex fear with a number of components.

Abstract
BACKGROUND The current US official position, since DSM-III, is that panic attacks represent the hallmark of panic disorder and play a major role in the development of the agoraphobic syndrome. The more favoured view in the European tradition is that neurotic personality and/or prodromal features such as mild depression and excessive worries precede the illness. METHOD We studied 126 consecutive cases of panic disorder with or without agoraphobia by DSM-III-R criteria, evaluated by relevant structured and semi-structured interviews. RESULTS We provide evidence that characterological and prodromal antecedents represent a putative phobic-anxious temperamental substrate occurring in at least 30% of our sample. This temperament consists of three or more of the following traits: (1) increased sympathetic activity with repeated sporadic and isolated autonomic manifestations; (2) marked fear of illness; (3) hypersensitivity to separation; (4) difficulty to leave familiar surroundings; (5) marked need for reassurance; (6) oversensitivity to drugs and substances. Our data further suggest that these attributes are of familial origin, as a result of which the illness tends to declare itself earlier. LIMITATION The present investigation is largely correlational without a prospective component; however, the key validating familial data were obtained blindly. CONCLUSION Our data support a pathogenetic model whereby genetic diathesis unfolds from subclinical to clinical manifestations along temperamental, panic, phobic and avoidant patterns. We submit that the delineation of the phobic-anxious temperament will be useful in more completely charting the life course of the panic-agoraphobic spectrum; avoidant and dependent (Axis II) patterns appear more distal in the pathogenetic chain and, in many cases, can be conceptualized to be epiphenomenal to the disease process.

Abstract
This study investigated a screening procedure for psychologic distress in adult patients with dental phobia before treatment of dental fear. The screening procedure was performed among 191 individuals in consecutive steps and included a medical/dental history, psychologic interviewing, and testing. Data collected during this process were analyzed and compared with SCL-90(R) data. The screening process was successful in selecting individuals without major psychologic distress problems. Among the excluded patients 91% had general symptoms scores on the SCL-90(R) exceeding a normative population mean, and 95% of included patients had a mean lower than an average for psychiatric outpatients. There were statistically significant differences between included and excluded patients on all subdimensions of the SCL-90. Thus, excluded patients had higher levels of psychologic distress, poorer psychosocial background, and more psychosomatic symptoms. This was accompanied by higher levels of negative attitudes toward dentists and their performance of dentistry, whereas no significant differences were found among the dental fear measures used.

Abstract
This study investigated the reported conditioned or cognitive origin of dental phobia in 100 adult patients at a specialized dental phobia clinic. It was shown that a majority of patients reported a conditioned background to their dental fear. Patients' avoidance time and level of dental anxiety corresponded to previously reported data for fearful groups. Individuals with an arousal conditioning etiology of dental fear reported significantly longer avoidance time as compared to individuals with a cognitively learned reaction. With the exception of an elevated level of general fears, most psychometrically assessed emotional reactions were well within normal ranges. However, patients with a non-conditioned, cognitive etiology reported significantly higher levels of trait anxiety and fear of embarrassment. In addition, a separate analysis among women revealed a greater fear of physical injuries among patients with cognitive etiology.

Abstract
Categories of extreme anxiety for dental treatment were derived using DSM-IV psychiatric criteria. A sample of 40 men and 40 women patients with extreme dental anxiety were initially evaluated with Dental Anxiety Scale (DAS), Trait Anxiety Inventory (STAI-T) and Geer Fear Scale (GFS). Patients all had DAS scores > or = 15 indicating extreme dental anxiety and were further evaluated with clinical interviews, Dental Fear Survey (DFS), Dental Beliefs Survey (DBS) and Mood Adjective Checklist (MACL). Results showed that 46% of 80 patients complained mainly of powerlessness and embarrassment about dental treatment while also having greater DBS scores than other categories, i.e. social phobia. Another 19% reported conditioned specific phobias (pain, drilling, injection, etc.) most often and lower DBS and GFS scores than other groups; while 35% had broader general anxiety complications, such as multiple phobias and agoraphobia with or without general anxiety symptoms (higher GFS and STAI-T compared to others). Symptoms of general anxiety disorder (GAD) were present in 30 of 80 patients, who had greater STAI-T and GFS and lower MACL scores than non-GAD patients. These results have implications for appropriate treatment strategies.

Abstract
The Diagnostic Interview Schedule was used to identify 89 incident social phobia cases in wave 2 household subjects from 9437 at risk persons age 18 or older as part of the Epidemiologic Catchment Area study. Crude annual incidence of Diagnostic Interview Schedule/DSM-III social phobia was estimated at 9 per 1000 population per year. Onset of social phobia was associated with low education, never having been married and female gender. First onsets occurred throughout the life course of this adult sample. Nervousness, headache, panic spells, palpitations, other phobias, binge pattern of alcohol consumption, dysthymia and schizophrenic symptoms were also predictive of social phobia onset. There was no difference in predictive factors when "primary" social phobia (without premorbid panic) was analyzed separately.

Abstract
The authors attempted to classify panic disorders into four types according to a clinical course and accompanying neurotic or depressive symptoms. The characteristics of each type are as follows; type I: a single panic attack is the only symptom, type II: only panic attacks occur frequently without any accompanying neurotic or depressive symptoms, type III: a recurrence of panic attacks and the gradual development of neurotic symptoms, such as anticipatory anxiety, generalized anxiety, agoraphobia, or hypochondriasis, type IV: depressive symptoms develop in the course of recurring panic attacks. Type IV is further divided into three subtypes. Type IV-1: depressive symptoms develop secondary to panic attacks and major depression later coexists with panic disorder. Type IV-2: panic disorder continuously changed into major depression. Type IV-3: panic attacks and depressive symptoms are seen independently. The most common types are type III and type IV-1, and seem to be a core group of the panic disorder. Typical cases of each type are presented and underlying psychopathology is discussed.

Abstract
We report the analyses of daily journal descriptions of 790 self-defined panic attacks from 59 patients meeting DSM-III criteria for panic disorder or agoraphobia with panic attacks. The DSM-III-R specified symptoms occurred with frequencies ranging from choking (17% of attacks) to palpitations (63% of attacks). The mean weekly panic attack severity correlated significantly with the number of symptoms per attack, but not their weekly frequency. Within a given person, situational and spontaneous panic attacks did not significantly differ over a number of characteristics, including severity, duration, frequency per week, diurnal distribution, and the number of symptoms per attack. Limited symptom attacks were less severe, but were otherwise similar to panic attacks. Also, panic attacks during sleep were less frequent than panic attacks in the awake state, but did not significantly differ on other descriptive characteristics. These data support the validity of the symptoms specified for panic attacks by DSM-III-R. They also suggest that within an individual, panic attacks of various subtypes may be descriptively similar, despite the differing contexts in which they arise. In addition, these data question the diagnostic significance of the limited symptom attack-panic attack distinction.

Abstract
Factors that predicted the outcome of drug treatment (alprazolam or imipramine) of panic disorder were studied in a sample of 123 Scandinavian patients participating in a multicenter placebo-controlled 8-week trial. The attrition rate was 95% for alprazolam, 73% for imipramine and 46% for placebo. For the intention-to-treat and 3-week-completer samples, drugs and anxiety symptoms at baseline were the best predictors of improvement on the Global Improvement Scale and on symptom scales focusing on panic attacks, phobic behavior and anticipatory anxiety. For completers of the 8-week trial, only baseline scores predicted outcome. Generally, more severe symptoms at baseline predicted a worse outcome. A subsample of patients had a marked placebo response. Avoidance, sex, age, childhood psychopathology and previous treatment experience had no or only a weak impact on the outcome. The relationship between panic disorder and mood disorder is presented elsewhere.

Abstract
Panic disorder (DSM-III, DSM-III-R) has been thoroughly studied in recent years. The main evidence for panic disorder as a nosological entity is reviewed, to delineate some important questions for future research. Validation criteria include epidemiological, phenomenological, genetic, neurobiological, pharmacological and behavioral findings. Biological, behavioral and psychodynamic considerations on etiology, pathogenesis and treatment are presented.

Abstract
Depressive symptoms are frequent in panic disorder. Among 123 Scandinavian patients participating in a placebo-controlled multicenter study of the efficacy of alprazolam and imipramine treatment in panic disorder, 21% and 23% fulfilled the DSM-III criteria of current and past major depressive episode, respectively, and 17% had dysthymia, even when melancholia and depressive episode with onset prior to the panic symptoms were excluded. According to a subscale of the Hamilton Rating Scale for Depression (HRSD) with higher validity than the full scale, 18% were classified as major depression and 57% as minor depression. A major finding was that patients with affective symptoms had higher scores on many psychopathological measures, including several Symptom Checklist-90 factors. Accordingly, secondary depression was suggested as an indicator of the severity of panic disorder. Depressed and nondepressed patients significantly improved on major outcome measures, but patients with current minor or major depression improved less. Although the sample was too small for detailed analysis of differences in drug efficacy, there was no indication that imipramine was more effective than alprazolam, considering scores on an HRSD subscale.

Abstract
This study aimed to clarify how manifestations and acquisition relate to diagnostic categories of dental fear in a population of self-referred dental fear patients, since diagnostic criteria specifically related to dental fear have not been validated. DSM III-R diagnostic criteria for phobias were used to compare with four existing dental fear diagnostic categories, referred to as the Seattle system. Subjects were 208 persons with dental fear who were telephone interviewed, of whom a subsample of 155 responded to a mailed Dental Anxiety Scale (DAS), State-Trait Anxiety Inventory and a modified FSS-II Geer Fear Scale (GFS). Personal interviews and a Dental Beliefs Scale of perceived trust and social interaction with dentists were also used to evaluate a subsample of 80 patients selected by sex and high dental fear. Results showed that the majority of the 80 patients (66%), suffered from social embarrassment about their dental fear problem and their inability to do something about it. The largest cause of their fear (84%) was reported to be traumatic dental experiences, especially in childhood (70%). A minority of patients (16%) could not isolate traumatic experiences and had a history of general fearfulness or anxiety. Analysis of GFS data for the 155 subjects showed that fear of snakes and injuries were highest among women; heights and injections among men. Fear of blood was rarely reported. Spearman correlations between GFS individual items and DAS scores indicated functional independence between dental fear and common fears such as blood, injections and enclosures in most cases. Only in specific types of dental fear did these results support Rachman and Lopatka's contention that fears are thought to summate.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Thirteen patients with panic disorder with predominantly cardiorespiratory (CR) symptoms were compared with seven patients with predominantly gastrointestinal (GI) symptoms in an experimental procedure that involved exposure to phobia talk and voluntary hyperventilation (VHV). The CR patients had not only higher baseline anxiety, but also during phobia talk had a greater fall in pCO2 and reported more respiratory symptoms than the GI patients. Moreover, the CR group found VHV more unpleasant and more like their panic attacks than the GI panickers, and reported more physical symptoms after it. These findings suggest that patients with PD are not only heterogeneous with respect to the system to which panic symptoms refer (Cr or GI) but that provoking arousal in one system is more likely to produce distress if that system is the major focus of complaint. These findings, if replicated, would not support the suggestion that panic disorder is a uniform illness.

Abstract
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.

Abstract
Seventy-three patients successively hospitalized in psychiatry and meeting the criteria of the DSM-III for diagnoses of major depressive episode with or without melancholia (n = 64), dysthymia (n = 5) or adjustment disorder with depressed mood (n = 2) were studied. Of these 73 patients, 50.7% also exhibited, at the time of their hospitalization, panic disorder as defined by the DSM-III criteria (53.4% having exhibited this disorder at some time in their life). Moreover, eight of the 73 patients (11%) exhibited, or had exhibited at some time in their life, a "sub-panic" state characterized by recurring rudimentary attacks, while five of the 73 patients (6.8%) exhibited "permanent panic anxiety" tending to fluctuation rather than paroxysm. These two forms of anxiety raise the question of the limits of panic disorder. The comparison of depressions with and without panic disorder shows an even distribution of endogenous and nonendogenous forms in both groups. Depressions with panic disorder, moreover, registered greater intensity (according to the HDRS score), a higher lever of anxiety (according to the AMDP-AT score), and a higher degree of nervousness (according to the EPI score) than depressions without panic disorder. The study of the chronology of the associations between depressions and panic disorder shows that in more than one-half of the cases these disorders began within one month of each other. In one-third of the cases, panic disorder preceded the depressive episode by more than one month. And finally, in just over 10% of the cases, panic disorder appeared more than one month after the beginning of the depressive episode.

Abstract
Corresponding categories for anxiety disorders, as defined by the classification systems of the ICD-9 and the DSM-III-R, were compared in a selected sample of 114 outpatients. An unequivocal category-to-category correspondence could not be demonstrated for any diagnosis. Anxiety states in ICD-9 were closely related to generalized anxiety and panic disorder in DSM-III-R, and most patients diagnosed as phobic according to ICD-9 received one of the specific phobia diagnoses of DSM-III-R. To some degree, diagnostic discrepancies were caused by coexisting symptoms of phobia, panic attacks and/or generalized anxiety within patients. A new technique is introduced to adjust corresponding proportions according to base rate differences.

Abstract
Panic attacks may be perceived by patients as either cued or uncued (spontaneous) and either expected or unexpected. The purpose of the present study was to examine the prevalence and characteristics of these types of panic. Twenty-six panic disorder patients with mild avoidance and 18 with moderate or severe avoidance were instructed to complete a questionnaire during or immediately following each of three consecutive naturally occurring panic attacks they experienced. They were asked to rate the extent to which they expected the panic attack to occur, whether they felt it was associated with an external panic "cue" (e.g. a shopping mall), whether they would expect to panic again in similar circumstances, their mood, present level of life stress, and fear and severity of their body sensations and disturbing cognitions. Results indicated that from a sample of 92 questionnaires, each representing a separate panic, nearly 70% of panic attacks were rated as cued-expected and only one panic was rated as uncued-expected. The other two categories each comprised about 15% of all panic attacks. There were few reported differences in body sensations and cognitions reported as a function of type of panic and no differences with regard to extent of agoraphobic avoidance. Expected panic was associated with a higher expectation of future panic in similar circumstances.

Abstract
The biological model proposed by Klein was evaluated. It was argued that agoraphobia is not invariably preceded by panic attacks, and Klein's observations may have been restricted to severe cases. Furthermore, there is a need to determine why some individuals who suffer from panic do not develop agoraphobia. The limitations of the basic premises concerning panic and anxiety, dependency needs, and separation anxiety are discussed. A comprehensive model of agoraphobia must consider the interaction between biological dysfunction and cognitive processes. In addition, several diagnostic groups should be compared to clarify which factors are specific to agoraphobia.

Abstract
Panic attacks during sleep are analysed in terms of a hyperventilation theory of panic disorder. The theory assumes that panic attacks during sleep are a manifestation of severe chronic hyperventilation, a dysfunctional state in which renal compensation has led to a relatively steady state of diminished bicarbonate. Reductions in respiration during deep non-REM sleep lead to respiratory acidosis which triggers hyperventilatory hypocapnea and subsequent panic. A probability model designed to predict when during sleep panic attacks are likely to occur is supported by relevant data from studies of sleep and panic attacks. Implications for treatment are discussed.

Abstract
1. One of the simplest and most direct applications of neuropsychophysiological techniques is to anxiety disorders. 2. The physiological changes accompanying the lactate induction of panic appear, for most response systems, to be similar to those found spontaneously in anxious patients and are characteristic of a state of hyperarousal. 3. Patients vulnerable to lactate-induced panic exhibit higher than normal pre-panic autonomic activity, elevated autonomic-somatic activity during lactate-induced panic and an EEG response to provoked panic which appears to be comprised of a "paradoxical" shift towards slow wave delta activity and an altered brainstem evoked response. 4. Additional studies are warranted to determine the relationship of these physiological changes to the triggering of panic and preliminary attempts in this direction are discussed.

Abstract
Theories on the aetiology of pathological anxiety abound. A critical review is given of the most influential approaches (e.g. psychoanalytical, "somatogenic", behavioural, psychophysiological and "biological" theories), with emphasis on panic and agoraphobic disorders. Evidence is presented from epidemiological and genetic research and from observations on the course of illness. A surprisingly constant prevalence of anxiety syndromes, and a familial distribution suggesting a pivotal importance of genetic factors, speak in favour of a biological model. The course of illness, however, points to the importance of environmental influences as triggering factors, and to cognitive and behavioural mechanisms for the perpetuation of the symptoms. Treatment responses hitherto documented support the biological and behavioural concepts, but the cognitive and psychophysiological theories are also supported to some extent. An attempt is made to combine these findings with biochemical and pharmacological findings in an integrated model of panic and agoraphobia. This model takes the form of a vicious circle, and is compatible with biological and neuropharmacological as well as evolutionary and psychological concepts.

Abstract
Many studies have suggested that a genetic predisposition to the development of panic disorder exists. These studies are examined and their limitations discussed. It is suggested that only by the analysis of comprehensive family and twin data, coupled with other measures such as the search for possible single gene association or linkage and study of the children of panic disorder patients, will the mechanism for the 'familiarity' noted in panic disorder patients be elucidated. Delineation of the mode of transmission of panic disorder may allow preventative intervention with those at risk before they develop panic.

Abstract
Panic disorder, as defined by the DSM III diagnostic criteria, was diagnosed in 117 probands for whom age of onset ranged from 10 to 59 years, with a mean of 26.6 years. Diagnosis of parents and siblings was based on interviews with the probands, and only those with "definite" panic disorder by the FISC criteria were considered to be affected. The pattern of concordances for panic across different groups of relatives was estimated concurrently by a log-linear model for binary pedigree data, assuming different values for the cumulative risk. When an adjustment for age was made, based on the age of onset of probands, there was no significant difference between parent-offspring concordance and sibling concordance. There was a negative, but not significant, concordance between spouse pairs. Assuming the lifetime cumulative risk was 1.9% for males and 4.7% for females, values considered appropriate for this population, our model predicted that the presence of an affected parent or sibling incurs an approximately five times increase in the risk of developing panic disorder. Our model assumes in effect that this risk is multiplied for each further affected relative. Although the common concordance across relationship groups is consistent with a genetic hypothesis, it can also be explained by common family environmental factors. There is a need for further pedigree studies, using twins and relatives, for example, and reliable information on the cumulative risk.

Abstract
Anxiety, phobic and related neurotic disorders lend themselves to diagnostic confusion because of the large and variable array of symptoms associated with them. This has complicated attempts at coherent classification. This paper examines the problems in diagnosis and classification and the diversity of causal models of these disorders. It offers an alternative integrated perspective that may have heurestic merit in guiding clinicians to a practical choice of treatment and in delineating a useful starting point for the biological investigation of these disorders.
