Association between cingulum bundle structure and cognitive performance: an observational study in major depression

BACKGROUND

Major depression can be regarded as a systemic neurobehavioral disorder resulting from dysfunction of the limbic-cortical networks. The cingulum bundle represents a major association fiber tract of those networks. The aim of our study was to determine the association of brain structural tissue markers of the cingulum bundle and cognitive function in patients with major depression.

METHODS

Region-of-interest-based analyses of the middle-anterior and middle-posterior cingulum bundle fractional anisotropy (FA) and mean diffusivity (MD) using color-coded diffusion-tensor imaging and neuropsychological assessment in 14 patients with major depression.

RESULTS

FA of the middle-anterior and middle-posterior cingulum bundle was significantly correlated to the performance in a planning and divided attention task. Furthermore, MD of the middle-posterior cingulum bundle was significantly correlated to a planning task. There was no significant correlation between FA and MD of the cingulum bundle and selective attention or memory.

CONCLUSIONS

Brain structural tissue markers of the middle-anterior and middle-posterior cingulum bundle were found to be associated with executive functioning and divided attention in patients with major depression. Disconnection within the limbic-cortical networks may underlay cognitive dysfunction in major depression.

[Cognitive training in rehabilitation: a program to treat mild cognitive impairment]

As part of a research project, a behavior therapy-oriented cognitive training program, designed to improve the cognitive ability of middle-aged employees (50 to 59 years), was implemented and evaluated. The goal of the training program was to analyze the cognitive, affective and behavior-related conditions of memory deficits in the workplace. The training focused on two topics: (1) development of new job tasks, (2) lack of time and deadline constraints. A total of 316 patients in the psychosomatic clinic of Bad Neustadt participated in the study. Those who showed cognitive impairments took part in the cognitive training program during the intervention phase. During the control phase, patients with cognitive impairments received no additional intervention. The neuropsychological screening was repeated with patients with cognitive impairments at discharge. The findings show that the objective and subjective memory performance of the participants improved significantly compared to that of the control group. At the 1-year follow-up, 84% of the participants reported that they could use the training strategies in their job.

Mid-term effectiveness of behavioral and psychodynamic inpatient treatments of severe obesity based on a randomized study

BACKGROUND

The objective of this study was to compare the effectiveness of psychodynamic and behavioral inpatient treatments of severely obese patients regarding weight and distress.

METHODS

In a longitudinal study obese patients (body mass index, BMI >or=35) were randomly assigned to behavioral or to psychodynamic inpatient treatment. Mostly female (n = 267; 85%) obese patients with psychiatric and somatic comorbidity (age 20-64 years, BMI 35-74) were examined with standardized self-report scales on distress (SCL-90R), interpersonal problems (Inventory of Interpersonal Problems), eating behavior (Fragebogen zum Essverhalten) and body image (Fragebogen zum Korperbild).

RESULTS

During 49 days (mean) of inpatient treatment, patients lost an average of 5.6 kg (4.4%) in the behavioral (n = 130) and 5.7 kg (4.4%) in the psychodynamic setting (n = 137). In both settings, eating behavior, well-being and body image also improved significantly. One year after discharge, return rate was 73%. Forty percent had further reduced their weight (by more than 5% compared to intake), 36% had regained weight, but were still below intake level, and another 24% had increased weight above intake.

CONCLUSION

Behavioral and psychodynamic treatments were equally effective reducing weight and distress over 1 year.

Fatigue assessment questionnaire: standardization of a cancer-specific instrument based on the general population

OBJECTIVES

Fatigue has become a major issue of concern in the care of cancer patients, as it has been shown to compromise their quality of life in a significant and lasting way. However, there is a lack of economic and specific measures. The Fatigue Assessment Questionnaire (FAQ) has been developed based on thorough interviews and tested on a large mixed sample of cancer patients. The purposes of this paper are to test the psychometric properties of the FAQ and to provide norms for the German population.

METHODS

The FAQ was administered to a representative sample of the German population (1,340 female and 1,101 male participants) along with standardized scales of depression, mood and life satisfaction.

RESULTS

We could confirm that fatigue is multidimensional and can be measured by the scales of physical, affective and cognitive fatigue with good reliability and validity. The dependency of fatigue on sex and age makes it useful to have standard fatigue scores for oncological research as provided in this paper.

CONCLUSION

The FAQ is a promising, differentiated, yet economic instrument for further use in oncological research.

Einstellungen zur postmortalen Organspende - Ergebnisse einer Repräsentativerhebung der deutschen Bevölkerung

The increasing deficit of organs causes a drastic decline in the quality of life and survival of numerous patients in need of a transplantation. The purpose of this representative community study was to survey attitudes toward transplantation in the German population and to identify underlying determinants. Unlike previous surveys, fears and concerns were elicited based on a concrete case vignette. Among the 1,002 participants, 90 % were in favour of organ donation in general; 21 % reported having signed an organ donor card. Consent to organ donation was associated with younger age and higher social class; the same was true for the possession of an organ donor card. In the virtual decision situation, the majority (77 %) voted in favour of an organ donation based on saving lives, consolation for bereaved and the absence of disadvantages for the donor. Common (up to 50 %), however, were also fears and concerns regarding determination of the time of death, displacement of medical concern from the donor to the recipient of the organ, utilisation of organs for other purposes, or explantation before death. The knowledge of the determinants identified, of existing fears and concerns are helpful not only for informing the public, but also for the dialogue with the next of kin of potential donors. Here, it may be helpful not only to address arguments pro organ donation, but also to address potential fears and concerns.

Aufmerksamkeit und exekutive Funktionen bei Patienten mit Adipositas per magna

In this paper, attention and temperament are compared between 41 severely obese patients with psychiatric comorbidity and 45 control persons. Networks of attention were assessed by the Attention Network Test: alerting (ability to achieve and maintain an alert state), orienting (ability to orient to a stimulus), and executive attention (ability to resolve conflict). According to hypotheses, obese patients show reduced executive attention, more effortful control, and higher negative affectivity than controls. The concept of attention networks is related to cognitive mechanisms of self-regulation, opening new perspectives for understanding psychiatric disorders.

Kognitive Auffälligkeiten, Depressivität und Leistungsfähigkeit bei älteren Arbeitnehmern in stationärer psychosomatischer Behandlung

Due to aging of the population and a possible rise in retirement age, the cognitive capacity of older people is gaining great importance. As evidenced by the increase in early retirement due to psychosomatic disease, many employees are not capable of working at a higher age. Decreasing cognitive abilities have usually been studied in subjects over 65 years based on the heterogeneous construct of mild cognitive impairment (MCI). This study investigates the prevalence of cognitive impairments in the age group from 50 to 59 years and their reflections in subjective vocational achievement and social medical evaluation. Having been assigned to inpatient rehabilitation due to decreasing work performance, these patients could be considered a risk group for developing MCI. A battery of standardized cognitive tests was conducted with patients at a psychosomatic hospital (Termine Test, CVLT, Block Design, TAP, and Tower of Hanoi). The MCI was defined by performance below the average age norm in at least two of five functional areas. Depression was assessed by the Beck Depression Inventory. Cognitive impairment was observed in 24% of participants. These patients also described vocational difficulties. Cognitive impairments of older employees could possibly be compensated for by specific training programs in order to maintain or rebuild their work capacity.

Epidemiology of sexual dysfunction in the male population

Sexual dysfunctions have found an increasing attention in recent epidemiological studies of the ageing male. The purpose of this paper is to review the prevalence of sexual dysfunctions and risk factors based on community samples. Studies have not only demonstrated a strong age-related incline of erectile dysfunction (ED), but also of ejaculatory and orgasmic disorders (particularly a reduced or absent ejaculation). Despite a declining sexual desire, sexual interest remains present in old age. Lower urinary tract symptoms have been identified as strong risk factors for ED along with cardiovascular, metabolic, psychiatric disorders and lifestyle factors. The wide range of prevalence rate estimates is likely because of different definitions and criteria of sexual dysfunctions. More research is needed on other dysfunctions besides ED and on the partner relationship as a major determinant of sexual activity and satisfaction. The interrelationship between risk factors calls for interdisciplinary prevention and treatment approaches. As disability-free life expectancy keeps increasing, the need to identify, adequately assess and treat male sexual dysfunction as an important impediment to quality of life most likely will become even more pressing.

Psychische Störungen und Psychotherapieeffekte in der funktionellen Bildgebung

Only recently has functional neuroimaging been used increasingly in the context of psychotherapy research. Based on a literature survey, procedures, methodological underpinnings and paradigms relevant for psychotherapy research are explored regarding functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). Current studies on changes of brain functions and potential mechanisms are presented based on obsessive-compulsive disorders, depression, phobia, panic and borderline personality disorders. Findings and implications are discussed regarding the use of functional neuroimaging in psychotherapy research. Systematic changes of brain activation were demonstrated following successful psychotherapy, partially resembling and partially differing from those induced by psychopharmacological treatments. Thus the traditional split between pharmacological procedures "acting on the brain" and psychological procedures making the patient "feel better" has been rendered obsolete. Procedures of functional neuroimaging have been developed to such an extent that they can be used to study issues of great relevance for psychotherapy, e. g. biological underpinnings of psychiatric disorders, plasticity of neural networks, mechanisms of change and prognostic factors of psychotherapy, etc.
