Interaction of genetic and psychosocial factors in stress-reaction patterns: a systems approach to the investigation of stress-coping mechanisms.

Selye refers to stress as 'the nonspecific response of the body to any demand made upon it'. Our experimental data indicate that: (1) there are significant constitutional differences in the types of stress reactions exhibited by different breeds of dogs; (2) inability to achieve an adaptive consummatory response or to develop a sense of control over stressful situations may lead in susceptible individuals (low adaptation dogs) to the development of maladaptive distress reactions, evidenced by persistent psychovisceral turmoil; (3) such maladaptive distress reactions represent a physiologic substrate of anxiety and frustration; (4) exposure of the low adaptation dogs to similar stressors but under conditions where the animals can develop avoidance responses, inhibited the psychovisceral disturbances, suggesting that it is the inability to develop control over psychosocially aversive situations that is primarily responsible for psychophysiologic disorders.

"Cyberphysiologic" strategies for children: the clinical hypnosis/biofeedback interface.

This article presents an in-depth discussion of the integrated use of self-hypnosis and biofeedback in the treatment of pediatric biobehavioral disorders. The rationale for integrating these techniques and their similarities and differences are discussed. The concepts of children's imaginative abilities, mastery, and self-regulation are examined as they pertain to these therapeutic strategies. Three case studies are presented that illustrate the integrated use of self-hypnosis and biofeedback in the treatment of children with psychophysiologic disorders. The authors speculate on the specific aspects of these self-regulation or "cyberphysiologic" techniques that appear particularly relevant to positive therapeutic outcomes.

Self-reports, spouse ratings, and psychophysiological assessment in a behavioral medicine program: an application of the five-factor model.

This article describes the integration of the five-factor model into assessment procedures used with 109 patients in an outpatient behavioral medicine program. The population, program, assessment techniques, and general findings are explored. A case history involving a psychophysiological disorder is utilized to demonstrate the utility of a taxonomy of personality traits. The NEO-PI, a five-factor instrument, is integrated with other assessment techniques to assist in diagnosis, rapport building with the patient, tailoring treatment techniques and goals to the individual's intrapersonal and interpersonal dynamics, and predicting relative success and compliance with noninvasive self-regulation procedures and psychotherapy.

Masseter muscle hyperactivity and myofascial pain dysfunction syndrome: a relationship under stress.

Myofascial pain dysfunction syndrome (MPD) of the temporomandibular joint (TMJ) is a psychophysiological disorder that develops because of hyperactive muscles of mastication. Ten women meeting criteria for MPD and 12 symptom-free women participated in the study. The rationale for this study was to observe cardiovascular and masseter muscle changes during four contiguous experimental periods: baseline/adaptation, reaction time, recovery, and relaxation. MPD patients showed less masseter muscle activity and higher heart rates at baseline than controls. Controls had significantly higher masseter EMG activity during reaction time. Both groups showed significant elevation in masseter muscle activity and heart rate over the 14-min reaction period. MPD patients' recovery from stress was equivalent to controls' for both heart rate and masseter muscle activity. MPD patients exhibited significantly slower reaction times than controls. The results suggest that masseter muscle hyperactivity may not account for the development and maintenance of MPD.

Specialist/generalist division of responsibility for patients with mental disorders.

The division of responsibility between general medical staff and mental specialists for care of persons with medical record diagnoses of mental disorders is documented in four organized health care settings. Rates of mental disorders identified in all departments ranged from 35.6 to 122.8 per 1,000 population. Specialty mental health departments treated most severe psychotic and personality disorders, plus transient situational disturbances, whereas neurotic, childhood behavior, and psychophysiological disorders received as much or greater attention in general medical departments. Mental disorder diagnoses were associated with greater patient use of general medical departments. However, joint specialty mental health/general medical treatment of these patients was associated with lower general medical department visit rates in all settings. Such joint care was facilitated by the low average visit frequency use of mental health departments. (2.2 to 8.9 visits per patient per year).

Desensitization therapy for body image anxiety.

A newly devised therapy technique to desensitize individuals for body image anxiety arising from conversion symptoms and psychophysiologic disorders is outlined. One application involves the projective use of inkblots with high anatomical content which provide a source of visual input to stimulate somatic images in consciousness. When these are activated in a state of relaxation the anxiety content of the pathologic anatomical imagery is reduced. A case history involving desensitization treatment for a psychoneurotic patient's psychophysiologic symptom of premature ejaculation is cited. It is primarily designed to alert interested clinical investigators to this technical innovation in treatment.

Differential rates of psychopathology symptoms in periodic limb movement disorder, obstructive sleep apnea, psychophysiological insomnia, and insomnia with psychiatric disorder.

STUDY OBJECTIVE: To determine patterns and relative intensity of psychopathology, as measured by the Minnesota Multiphasic Personality Inventory (MMPI), in 108 patients with either psychophysiological insomnia (PI; n=20), insomnia with psychiatric disorder (IPD; n=30), periodic limb movement disorder (PLM; n=28), or obstructive sleep apnea (OSA; n=30). DESIGN: Cross-sectional. SETTING: University sleep disorders center. MEASUREMENTS AND RESULTS: Subjects completed the MMPI prior to overnight diagnostic polysomnographic assessment followed by Multiple Sleep Latency Test (MSLT). Seventy five percent of the entire sample had at least one MMPI elevation (T>70). Groups showed significant baseline differences in age, BMI, and MSLT latency (all ps<.05). Logistic regression indicated that even after statistically controlling for these three diagnostic covariates, MMPI elevation was more likely among PLM and IPD patients than OSA or PI patients (all ps<.05). Followup pairwise comparisons indicated that this same pattern of group differences occurred for the Depression, Psychasthenia, and Schizophrenia scales (all ps<.05). CONCLUSIONS: Irrespective of age, obesity, and daytime sleepiness, patients with untreated PLM or IPD are more likely to experience clinically significant psychological difficulties than those with either OSA or PI. These differences are most likely to be manifested in terms of depressive symptoms, anxiety symptoms (tension, worry, guilt), social alienation, and diminished mental concentration. Finally, PLM may be associated with greater MMPI elevations than previously suspected, and agree with earlier clinical reports of high rates of psychiatric treatment in PLM.

Neurofeedback treatment of children with attention deficit hyperactivity disorder.

BACKGROUND: Biofeedback is a modern computer-related technique used for assessment and therapy of many psychophysiological disorders, especially stress-related ones. After a short overview of the basic concepts of biofeedback, in this study the application of EEG biofeedback (neurofeedback) in the assessment of and therapy for attention deficit hyperactivity disorders (ADHD) is presented and discussed. METHODS: The study comprised 12 children diagnosed as ADHD, selected according to ICD-10, and assessed by WISC-R, Q-EEG, neurofeedback and Conner's questionnaire for parents and teachers. The mean age was 9.5 years (7 to 13), both sexes. Each of them participated in a five-month programme of neurofeedback training, performed two times weekly with Biograph/ProComp 2.0 protocols. RESULTS: Post-treatment results showed an improved EEG pattern expressed in increased 16-20 Hz (beta) activity and decreased 4-8 Hz (theta) activity. In parallel, higher scores on WISC-R, better school notes and improved social adaptability and self-esteem were obtained. CONCLUSIONS: EEG biofeedback operant conditioning is a good choice for treatment of ADHD children. The method is non-invasive and has high cost-benefit. Optimal results are obtained in children of higher age. Cooperation with family members and teachers is crucial.

How information processing mode could affect prostaglandin E1 metabolism and lung inactivation: relevance of hemispheric specialization, neurotransmitter asymmetry and brain reactivity.

Due to asymmetry of brain neurotransmitters and differential hemispheric information processing modes, it is suggested that the excessive use of one information processing mode could engender a state of brain reactivity whose neurochemical correlates would be either a rise in melatonin or beta-endorphin in systemic circulation. Since melatonin and beta-endorphin have opposite effects on lung-mediated regulation of prostaglandins, it is further suggested that the pulmonary inactivation of prostaglandin E1 would either be increased or inhibited. Low levels of PGE1 would engender high levels of PGE2 whose effects would explain the findings in schizophrenics of: 'reducing' pattern of visual evoked response, cerebral atrophy, and viral and autoimmune phenomena. The primacy of the disordered cognitive style in leading up to the immunological, biochemical and neuropathological processes is stressed. Implications of this model for understanding depression, anxiety and phobic disorders, autism, attention deficit disorder, obesity, alcoholism, smoking, drug addiction, sexual deviations, and certain psychosomatic and psychophysiological disorders are suggested.

Iowa record-linkage study: death rates in psychiatric patients.

The Iowa record-linkage study was developed to investigate death rates in psychiatric patients, and involved computer matching of death certificates with a roster of patients. A list of all patients admitted to our hospital from 1972 through 1981 was obtained and after removing duplicate entries the list was pared to 5412 names. The record included multiple identifiers (e.g., name, gender, date-of-birth, hospital number). This information was then linked by computer with all Iowa death certificates for the same period; a total of 331 deaths were identified. Patients were assigned to a single psychiatric diagnostic category based on a computer program that reviewed each patient's clinical diagnoses and picked the one with the highest priority in a hierarchy we had created. Age and sex adjusted mortality tables were constructed, allowing us to compute expected numbers of deaths. Relative risk for premature death was greatest among women, and those under 20 years. Risk was associated with all psychiatric diagnoses and was significantly higher among patients of either gender with an organic mental disorder or schizophrenia; women with acute schizophrenia, depressive neuroses, alcoholism, drug abuse, and psychophysiological disorders; and men with neuroses. Death from natural causes, especially from heart disease, was significantly excessive among women, while death from accidents and suicides was excessive for both men and women. The overall SMR was 1.65 (P < 0.001). Most importantly, we found that the greatest excess of mortality occurred within the first 2 years following hospital discharge. Thus, we were able to demonstrate that risk of mortality in general, and of suicide specifically, differed according to age, gender, diagnosis, and portion of the follow-up. We have subsequently used this method to investigate specific risk factors associated with mortality in mood disorders, schizophrenia, and antisocial personality disorder. Findings from these studies are reported.

Psychophysiology of the posttraumatic stress disorder: from sulfur fumes to behavioral genetics.

Neurophysiological hypotheses regarding the body-mind relationship in stress disorders have been formulated more than 300 years ago. In 1941 Abraham Kardiner ascribed the name "physioneurosis" to the condition known today as posttraumatic stress disorder (PTSD). Psychophysiological studies of PTSD started with the demonstration of increased responsiveness to external stimuli reminiscent of the traumatic event. Later, abnormal responses to mental imagery were studied, and these studies have resulted in new tools for the assessment and diagnosis of the disorder. Recent studies focus on responses to elementary stimulation, such as the auditory startle reflex, thereby exploring basic CNS routines of habituation and stimulus-discrimination. This article reviews the rapidly expanding literature on the psychophysiology of PTSD. Special emphasis is given to recent studies of the auditory startle and to their implications for the neurobiology of PTSD.

Idiopathic environmental intolerance: increased prevalence of panic disorder-associated cholecystokinin B receptor allele 7.

BACKGROUND: A growing body of evidence suggests that idiopathic environmental intolerance (IEI) is a psychophysiologic disorder with prominent features of anxiety/panic and somatization, although proponents of a toxicogenic explanation claim, despite a lack of convincing evidence, that symptoms arise from exposure to otherwise nonnoxious environmental agents. Patient behaviour is characterized by strenuous avoidance of perceived triggers to the point of severe impairment of normal social and vocational functioning. IEI proponents claim that previous studies showing a high prevalence of psychopathology in patients with IEI and studies showing panic responses to known panicogenic challenges merely reflect the anxiety-producing result of living with IEI. OBJECTIVE: We explored whether IEI and panic disorder, personality traits, or both shared an underlying neurogenetic basis that would predate the anxiety of IEI symptomatology. The DNA of patients with IEI was examined for the presence of known panic disorder-associated cholecystokinin B (CCK-B) receptor alleles and for personality trait-associated dopamine D4 receptor polymorphisms. METHODS: Eleven patients with typical IEI symptoms were recruited and were individually matched to normal control subjects from an existing bank for age, sex, and ethnic background. Genomic DNA was extracted from peripheral blood samples. CCK-B and dopamine D4 receptor polymorphisms were examined by using standard PCR-based techniques. RESULTS: There was a significantly higher prevalence of the panic disorder-associated CCK-B receptor allele 7 in subjects with IEI (9/22 [40.9%]) compared with control subjects (2/22 [9.1%], P =.037). There was no difference in personality trait-associated polymorphisms of the gene encoding dopamine D4 receptor between patients and control subjects. CONCLUSIONS: These findings provide preliminary evidence that IEI and panic disorder share a common neurogenetic basis, which would predate the anxiety-producing effects of IEI symptoms. Further studies with larger samples are warranted, but these results support previous studies that suggest that panic disorder may account for much of the symptomatology in at least some cases of IEI and provide a basis for rational treatment strategies.

Childhood trauma, borderline personality symptomatology, and psychophysiological and pain disorders in adulthood.

In the empirical literature, there is support for the idea of a relationship between childhood trauma and various psychophysiological as well as pain disorders, and between borderline personality symptomatology and somatic preoccupation, as well as chronic pain. However, to date, no single study has examined the relationships between childhood trauma and borderline personality symptomatology, and the number of psychophysiological and pain disorders in adulthood. In this study, the authors examined these relationships and found no significant correlation between borderline personality symptomatology and the number of psychophysiological and pain disorders. However, there were positive and significant correlations between childhood physical abuse, emotional abuse, and witnessing violence and the number of psychophysiological and pain disorders in adulthood. Using hierarchical-regression analyses to determine which specific childhood traumas significantly predicted the number of psychophysiological and pain disorders, only witnessing violence emerged, accounting for 12% of the variance. These data suggest that a general factor associated with various forms of trauma predicts number of psychophysiological and pain disorders and that a specific predictor may be witnessing violence in childhood.
