Eating disorder treatment in routine clinical care: A descriptive study examining treatment characteristics and short-term treatment outcomes among patients with anorexia nervosa and bulimia nervosa in Germany and Switzerland.

This descriptive study examined patient characteristics, treatment characteristics, and short-term outcomes among patients with Anorexia Nervosa (AN) and Bulimia Nervosa (BN) in routine clinical care. Results for patients receiving full-time treatment were contrasted with results for patients receiving ambulatory treatment. Data of a clinical trial including 116 female patients (18-35 years) diagnosed with AN or BN were subjected to secondary analyses. Patients were voluntarily admitted to one of nine treatment facilities in Germany and Switzerland. Patients received cognitive-behavioral interventions in accordance with the national clinical practice guidelines for the treatment of EDs under routine clinical care conditions, either as full-time treatment or ambulatory treatment. Assessments were conducted after admission and three months later. Assessments included a clinician-administered diagnostic interview (DIPS), body-mass-index (BMI), ED pathology (EDE-Q), depressive symptoms (BDI-II), symptoms of anxiety (BAI), and somatic symptoms (SOMS). Findings showed that treatment intensity differed largely by setting and site, partly due to national health insurance policies. Patients with AN in full-time treatment received on average 65 psychotherapeutic sessions and patients with BN in full-time treatment received on average 38 sessions within three months. In comparison, patients with AN or BN in ambulatory treatment received 8-9 sessions within the same time. Full-time treatment was associated with substantial improvements on all measured variables for both women with AN (d = .48-.83) and BN (d = .48-.81). Despite the relatively small amount of psychotherapeutic sessions, ambulatory treatment was associated with small increases in BMI (d = .37) among women with AN and small improvements on all measured variables among women with BN (d = .27-.43). For women with AN, reduction in ED pathology were positively related to the number of psychotherapeutic sessions received. Regardless of diagnosis and treatment setting, full recovery of symptoms was rarely achieved within three months (recovery rates ranged between 0 and 4.4%). The present study shows that a considerable amount of patients with EDs improved after CBT-based ED treatment in routine clinical care within three months after admission. Intensive full-time treatment may be particularly effective in quickly improving ED-related pathology, although full remission of symptoms is typically not achieved. A small amount of ambulatory sessions may already produce considerable improvements in BN pathology and weight gain among women with AN. As patient characteristics and treatment intensity differed largely between settings, results should not be interpreted as superiority of one treatment setting over another. Furthermore, this study shows that treatment intensity is quite heterogeneous, indicating the possibility for increasing effectiveness in the treatment of EDs in routine clinical care.

[Patient satisfaction with psychiatric day-care and inpatient treatment: Effects on physical and mental health]. / Zufriedenheit mit (teil-)stationärer psychiatrischer Behandlung: Effekte auf die physische und psychische Gesundheit.

INTRODUCTION: Quality assessment from the patient's point of view makes it possible to identify negative quality developments at an early stage. The focus is not on the medical result, but on what the patient wants. Correlations between patient satisfaction and physical and psychological treatment outcome were already shown in the 1990s. However, studies using rather unspecific satisfaction measures are scarce. The aim of this study was to investigate the influence of patient satisfaction with the treatment and the therapies offered on the extent of recovery. METHODS: In this prospective study, a questionnaire developed for the differentiated recording of patient satisfaction with the therapy offerings of the LWL-Klinik Dortmund was used in a day-care/hospital setting. The structure of the questionnaire was tested by means of explorative factor analysis. The factors generated in this way served as the basis for the hierarchical regression analyses in the further course. In addition to important treatment aspects from the patient's point of view, the subjective health status was recorded by means of SF-36. RESULTS: 105 patients participated in the study (64% female, 84% diagnosed with depression). Significant predictors for physical health were well-being after exercise therapy and satisfaction with the weekly structure of services. Significant predictors for mental health were age at onset of illness, age, perceived benefits from exercise therapy as well as occupational therapy, treatment duration and setting. DISCUSSION: The demonstrated impact of patient satisfaction on mental health highlights the relevance of treatment quality improvement to recovery.

Treatment of Bipolar Disorders in Older Adults: A Review.

Background: Old age bipolar disorder has been an orphan of psychiatric research for a long time despite the fact that bipolar disorder (BD)-I and II together may affect 0.5-1.0% of the elderly. It is also unclear whether aetiology, course of illness and treatment should differ in patients with a first manifestation in older age and patients suffering from a recurrence of a BD known for decades. This narrative review will summarize the current state of knowledge about the epidemiology, clinical features, and treatment of BD in the elderly. Methods: We conducted a Medline literature search from 1970 to 2021 using MeSH terms "Bipolar Disorder" × "Aged" or "Geriatric" or "Elderly". Search results were complemented by additional literature retrieved from examining cross references and by hand search in text books. Summary of findings: Varying cut-off ages have been applied to differentiate old age from adult age BD. Within old age BD, there is a reasonable agreement of distinct entities, early and late-onset BD. They differ to some extent in clinical symptoms, course of illness, and some co-morbidities. Point prevalence of BD in older adults appears slightly lower than in working-age adults, with polarity of episodes shifting towards depression. Psychopharmacological treatment needs to take into account the special aspects of somatic gerontology and the age-related change of pharmacokinetic and pharmacodynamic characteristics. The evidence for commonly used treatments such as lithium, moodstabilizing antiepileptics, antipsychotics, and antidepressants remains sparse. Preliminary results support a role of ECT as well as psychotherapy and psychosocial interventions in old age BD. Conclusions: There is an obvious need of further research for all treatment modalities of BD in old age. The focus should be pharmacological and psychosocial approaches, as well as their combination, and the role of physical treatment modalities such as ECT.Appeared originally in Ann Gen Psychiatry 2021; 20:1.

Consequences of exposure to the thin ideal in mass media depend on moderators in young women: An experimental study.

This study examined the consequences of media exposure to thin ideals compared to pictures of landscapes in healthy young women and women with eating and mixed mental disorders and investigated whether appearance-related cognitive factors and cognitive distortions moderate the effects. Two hundred seventy-five women in a multisite laboratory trial (174 in- or outpatients and 101 healthy women; Mage 22.87 years, SD = 3.94) were exposed to either thin ideals or to landscape pictures and guided through a vivid imagery of these pictures thereafter. Changes in body image dissatisfaction, mood, eating behavior, and physiological markers were assessed. After thin ideal exposure and even more after guided imagery, women's body image dissatisfaction increased and mood declined. The effect on mood was most pronounced in women with eating disorders, less in women with mixed disorders, and smallest in healthy controls. No effects were found on physiological measures. Higher values of appearance-related cognitive factors moderated the effect of thin ideal exposure and guided imagery on all psychological outcomes. Cognitive distortions moderated the effect of thin ideal exposure and guided imagery on mood. Findings indicate an overall susceptibility to viewing thin ideal pictures in magazines in young and especially in women with eating disorders. Though exposure in the laboratory resulted in psychological effects, it did not lead to a physiological stress response. The impact of thin ideal exposure on mood is in line with affect-regulation models in eating disorders, with appearance-related cognitive factors and cognitive distortions potentially accelerating such effects.

Adjuvant Guided Exercise Therapy Versus Self-Organized Activity in Patients With Major Depression.

Exercise seems to be effective in reducing depression itself, as well as the risk of relapse. This study evaluated whether standardized guided exercise therapy (GET) in comparison with self-organized activity (SOA) is an effective augmentation therapy in depressive adults. A total of 111 inpatients (66.7% women; mean age, 45.05 ± 12.19 years) with major depression were randomly assigned to either GET or SOA. Interventions were performed three times a week, with each session lasting 50 minutes. Both GET and SOA exerted effects even after a short-term application of 6 weeks. GET was superior to SOA in reducing depression symptom severity, as measured by the Hamilton Depression Scale (p = 0.017), specifically improving suicidality (p = 0.028) as well as time (p = 0.003) and severity of diurnal variation (p = 0.027). The findings support the beneficial role of adjuvant GET in patients with major depression as a feasible treatment in a psychiatric short-term inpatient setting.

Interpersonal theory of suicide: prospective examination.

BACKGROUND: The interpersonal theory of suicide (IPTS) is one of the most intensively researched contemporary theories on the development of suicidal ideation and behaviour. However, there is a lack of carefully conducted prospective studies. AIMS: To evaluate the main predictions of the IPTS regarding the importance of perceived burdensomeness, thwarted belongingness and capability for suicide in predicting future suicide attempts in a prospective design. METHOD: Psychiatric in-patients (n = 308; 53.6% (n = 165) female; mean age 36.82 years, s.d. = 14.30, range 18-81) admitted for severe suicidal ideation (n = 145, 47.1%) or a suicide attempt completed self-report measures of thwarted belongingness, perceived burdensomeness, capability for suicide, hopelessness, depression and suicidal ideation as well as interviews on suicide intent and suicide attempts and were followed up for 12 months. Logistic regression and receiver operating characteristics (ROC) analysis were conducted. RESULTS: The interaction of perceived burdensomeness, thwarted belongingness and capability for suicide was not predictive of future suicide attempts, but perceived burdensomeness showed a significant main effect (z = 3.49, P < 0.01; OR = 2.34, 95% CI 1.59-3.58) and moderate performance in screening for future suicide attempts (area under the curve AUC = 0.729, P < 0.01). CONCLUSIONS: The results challenge the theoretical validity of the IPTS and its clinical utility - at least within the methodological limitations of the current study. Yet, findings underscore the importance of perceived burdensomeness in understanding suicidal ideation and behaviour.

Drug-Induced Liver Injury (DILI) in Patients with Depression Treated with Antidepressants: A Retrospective Multicenter Study.

INTRODUCTION: Drug-induced liver injury (DILI) is the 4th most common cause of liver damage in Western countries and can be caused by antidepressants. METHODS: Against the background of increasing antidepressant prescriptions and increasing use of polypharmacy, we analyzed administered antidepressants and other pharmacological substances, liver toxicity, comorbid somatic secondary diseases together with the occurrence of DILI in a patient population of 6 centers throughout Germany. RESULTS: The majority of the enrolled 329 patients received polypharmacological treatment in an inpatient setting. During antidepressant treatment 5.1% of the patients had elevated serum transaminase levels, whereby exactly and not more than 1 criterion proposed to be indicative for DILI, was fulfilled by 3 patients (0.9%). DISCUSSION: During patient characterization it becomes clear that a sensitization for relevant risk constellations causing liver injury in MDD patients is relevant to prevent further serious adverse events.

Ward Atmosphere and Patient Satisfaction in Psychiatric Hospitals With Different Ward Settings and Door Policies. Results From a Mixed Methods Study.

Background: Open-door policies in psychiatry are discussed as a means to improve the treatment of involuntarily committed patients in various aspects. Current research on open-door policies focuses mainly on objective effects, such as the number of coercive interventions or serious incidents. The aim of the present study was to investigate more subjective perceptions of different psychiatric inpatient settings with different door policies by analyzing ward atmosphere and patient satisfaction. Methods: Quantitative data on the ward atmosphere using the Essen Climate Evaluation Scale (EssenCES) and on patient satisfaction (ZUF-8) were obtained from involuntarily committed patients (n = 81) in three psychiatric hospitals with different ward settings and door policies (open, facultative locked, locked). Furthermore, qualitative interviews with each of 15 patients, nurses, and psychiatrists were conducted in one psychiatric hospital with a facultative locked ward comparing treatment in an open vs. a locked setting. Results: Involuntarily committed patients rated the EssenCES' subscale "Experienced Safety" higher in an open setting compared with a facultative locked and a locked setting. The subscale "Therapeutic Hold" was rated higher in an open setting than a locked setting. Regarding the safety experienced from a mental health professionals' perspective, the qualitative interviews further revealed advantages and disadvantages of door locking in specific situations, such as short-term de-escalation vs. increased tension. Patient satisfaction did not differ between the hospitals but correlated weakly with the EssenCES' subscale "Therapeutic Hold." Conclusion: Important aspects of the ward atmosphere seem to be improved in an open vs. a locked setting, whereas patient satisfaction does not seem to be influenced by the door status in the specific population of patients under involuntary commitment. The ward atmosphere turned out to be more sensitive to differences between psychiatric inpatient settings with different door policies. It can contribute to a broader assessment by including subjective perceptions by those who are affected directly by involuntary commitments. Regarding patient satisfaction under involuntary commitment, further research is needed to clarify both the relevance of the concept and its appropriate measurement.

Facial Emotion Recognition Abilities in Women Experiencing Eating Disorders.

OBJECTIVE: Impairments in facial emotion recognition are an underlying factor of deficits in emotion regulation and interpersonal difficulties in mental disorders and are evident in eating disorders (EDs). METHODS: We used a computerized psychophysical paradigm to manipulate parametrically the quantity of signal in facial expressions of emotion (QUEST threshold seeking algorithm). This was used to measure emotion recognition in 308 adult women (anorexia nervosa [n = 61], bulimia nervosa [n = 58], healthy controls [n = 130], and mixed mental disorders [mixed, n = 59]). The M (SD) age was 22.84 (3.90) years. The aims were to establish recognition thresholds defining how much information a person needs to recognize a facial emotion expression and to identify deficits in EDs compared with healthy and clinical controls. The stimuli included six basic emotion expressions (fear, anger, disgust, happiness, sadness, surprise), plus a neutral expression. RESULTS: Happiness was discriminated at the lowest, fear at the highest threshold by all groups. There were no differences regarding thresholds between groups, except for the mixed and the bulimia nervosa group with respect to the expression of disgust (F(3,302) = 5.97, p = .001, η = .056). Emotional clarity, ED pathology, and depressive symptoms did not predict performance (RChange ≤ .010, F(1,305) ≤ 5.74, p ≥ .079). The confusion matrix did not reveal specific biases in either group. CONCLUSIONS: Overall, within-subject effects were as expected, whereas between-subject effects were marginal and psychopathology did not influence emotion recognition. Facial emotion recognition abilities in women experiencing EDs compared with women experiencing mixed mental disorders and healthy controls were similar. Although basic facial emotion recognition processes seems to be intact, dysfunctional aspects such as misinterpretation might be important in emotion regulation problems.

Risk-taking propensity and (un)healthy behavior in Germany.

BACKGROUND: Earlier research in South Africa (Szrek et al., 2012) confirmed the one-item Dohmen measure (Dohmen et al., 2011) to be a significant predictor of risky health behavior. METHODS: The present study investigated the relationship of the Dohmen measure with other measures of risk-taking propensity (e.g., Domain-Specific Risk-Taking scale), and its predictive power for smoking, problematic drinking, problematic car driving, and problematic sexual behavior, in a sample of 63 patients of psychiatric clinics and 102 healthy participants in Germany. RESULTS: The Dohmen measure was significantly positively related to other involved instruments. It served as predictor of two of the four investigated risky health activities (i.e., smoking, problematic drinking). CONCLUSIONS: The Dohmen measure seems to be a valid and time efficient instrument to assess general risk-taking propensity, as well as specific propensity for smoking and problematic drinking in Germany.

Self-reported emotion regulation difficulties are associated with mood but not with the biological stress response to thin ideal exposure.

BACKGROUND: Difficulties in emotion regulation have been related to psychological and physiological stress responses such as lower mood and lower parasympathetic activation (HF-HRV) under resting condition, but evidence on the potential link to the hypothalamic-pituitary-adrenal (HPA) axis functioning and to physiological stress responses during a stress task is still scarce. The aim of the study was to investigate stress responses in young women when confronted to a daily stressor such as exposure to thin ideals and to understand the role of correlates of self-reported trait-like emotion regulation difficulties (ERD). METHODS: Heart rate variability (HRV) and salivary cortisol data were collected in a sample of 273 young women aged 18-35 with and without mental disorders during a vivid imagination of thin ideals (experimental condition) or landscapes (control condition). Changes in mood states were measured on a visual analogue scale (0-100). Correlates of trait-like ERD were self-reported using the Difficulties in Emotion Regulation Scale (DERS). RESULTS: Participants with higher ERD showed a stronger decline in self-reported mood after vivid imagination of thin ideals compared to participants with lower ERD in the experimental condition but also a stronger increase of positive mood with increasing ERD in the control condition. ERD were not related to baseline HF-HRV or baseline salivary cortisol levels nor to any physiological response during and after the imagination of thin ideals. DISCUSSION AND CONCLUSION: The results corroborate the role of ERD regarding the immediate psychological impact of daily stressors. Exposition to daily stressors in the laboratory results in discrepant psychological and physiological reactivity. Future studies should investigate under what conditions the complex interrelations between immediate and long-term ERD and biological activation are amenable to assessment in a laboratory setting. The additive effects of multiple exposition to stressors, such as thin ideals in daily life, also need to be addressed.

Approach bias modification in inpatient psychiatric smokers.

Drug-related automatic approach tendencies contribute to the development and maintenance of addictive behavior. The present study investigated whether a nicotine-related approach bias can be modified in smokers undergoing inpatient psychiatric treatment by using a novel training variant of the nicotine Approach-Avoidance-Task (AAT). Additionally, we assessed whether the AAT-training would affect smoking behavior. Inpatient smokers were randomly assigned to either an AAT-training or a sham-training condition. In the AAT-training condition, smokers were indirectly instructed to make avoidance movements in response to nicotine-related pictures and to make approach movements in response to tooth-cleaning pictures. In the sham-training condition, no contingency between picture content und arm movements existed. Trainings were administered in four sessions, accompanied by a brief smoking-cessation intervention. Smoking-related self-report measures and automatic approach biases toward smoking cues were measured before and after training. Three months after training, daily nicotine consumption was obtained. A total of 205 participants were recruited, and data from 139 participants were considered in the final analysis. Prior to the trainings, smokers in both conditions exhibited a stronger approach bias for nicotine-related pictures than for tooth-cleaning pictures. After both trainings, this difference was no longer evident. Although reduced smoking behavior at posttest was observed after both trainings, only the AAT-training led to a larger reduction of nicotine consumption at a three-month follow-up. Our preliminary data partially support the conclusion that the AAT might be a feasible tool to reduce smoking in the long-term in psychiatric patients, albeit its effect on other smoking-related measures remains to be explored.

Attachment, recalled parental rearing, and ADHD symptoms predict emotion processing and alexithymia in adults with ADHD.

BACKGROUND: The aim of the aricle is to study the relationship between attachment, parental rearing behavior, and (infant and current) ADHD symptoms with emotion processing and alexithymia in adults with ADHD. METHODS: Attachment, parental behavior, and ADHD variables were tested for predictive value regarding emotion processing and alexithymia in the total sample, the pooled ADHD groups (with inattentive type and combined type, each with n = 26) and a control group (n = 26). Comparisons were performed between the pooled ADHD groups and the control group, and between the ADHD subtype groups regarding all emotion processing and alexithymia, and attachment-related measures. RESULTS: Emotion processing/alexithymia parameters were mainly predicted by early or current attachment-related features, and, to a lesser extent, by childhood or current ADHD symptoms, primarily in the ADHD groups. CONCLUSIONS: The findings suggest partly specific and possibly causal relationships between attachment-related features and current emotion processing/alexithymia in adults with ADHD. The results confirm the necessity for further study of the multiple interactions between infant and parental ADHD symptoms, aversive parenting, and attachment with respect to emotional functioning in adult ADHD.

Evaluation of basal ganglia, brainstem raphe and ventricles in bipolar disorder by transcranial sonography.

Transcranial brain sonography (TCS) has become a reliable and sensitive diagnostic tool in the evaluation of extrapyramidal movement disorders. Alterations of brainstem raphe (BR) have been depicted by TCS in major depression but not in bipolar disorder. The aim of our study was to evaluate BR echogenicity depending on the different conditions of bipolar patients. Echogenicities of dopaminergic basal ganglia structures were assessed for the first time in bipolar disorder. Thirty-six patients with bipolar I disorder (14 depressed, 8 manic, 14 euthymic) were compared to 35 healthy controls. Echogenicities were investigated according to the examination protocol for extrapyramidal disorders using a Siemens Sonoline® Elegra system. The sonography examiner was blinded for clinical rating scores. Six patients (16.7%) showed hyperechogenicity of the substantia nigra. The raphe was hypoechogenic in 13 (36.1%) of the patients. No significant differences were seen between the subgroups. Compared to the control group, frequency of altered echogenicities did not reach statistical significance. The width of third ventricle was significantly larger in the patient group (3.8±-2.1 mm vs. 2.7±1.2 mm). Depressed bipolar patients with reduced BR echogenicity showed significantly higher scores on the Hamilton Depression Rating Scale as well as the Montgomery-Åsberg Depression Rating Scale. In contrast to unipolar depression, sonographic findings of bipolar patients may generally indicate structural integrity of mesencephalic raphe structures. If bipolar disorder coexists with hypoechogenic raphe structure, depressive symptoms are more severe.

Association between wind-up ratio and central serotonergic function in healthy subjects and depressed patients.

Temporal summation of C-fiber evoked responses generates an increase in action potential discharge in second-order neurons and in perceived pain intensity (wind-up). This may be related to the central serotonergic system which modulates and partly inhibits sensory input. Aim of the study was to investigate the relationship between wind-up and serotonergic activity using loudness dependence of auditory evoked potentials (LDAEP). 18 healthy subjects were compared to 18 patients with major depression, a disease with a putative serotonin deficit. They were examined with quantitative sensory testing (QST) using the protocol of the German Research Network on Neuropathic Pain (DFNS), including the wind-up ratio (WUR), LDAEP, and psychometric measurements. We found a slight positive correlation between WUR and LDAEP both in healthy controls and depressed patients combined (r=0.340, p=0.043), indicating that WUR may be modulated by serotonergic activity. It can be concluded that inhibitory control to noxious stimuli is partly associated with the central serotonergic function as indicated by LDAEP.

Theory of mind and neurocognitive functioning in patients with bipolar disorder.

OBJECTIVES: Studies into social cognition in psychiatric disorders have recently been expanded to address the question of whether or not theory of mind (ToM), i.e., the ability to represent ones own and others mental states, is impaired in bipolar affective disorder (BPD). Results have been mixed so far, mainly due to possible confounding effects of neurocognition, as well as clinical factors such as acuity and current mood. Here, we explored ToM and its associations with neurocognitive functioning in BPD. METHODS: A total of 33 patients with bipolar I disorder (of whom 12 were currently depressed, 10 manic, and 11 remitted) and 29 healthy controls were assessed using a test battery that was identical to the one that was used in previous studies in schizophrenia, comprising diverse neurocognitive tasks, including measures of intelligence, executive functioning, and ToM tasks. RESULTS: The bipolar disorder patient group as a whole and all three clinical subgroups were impaired on all measures of ToM relative to controls, but did not differ from each other in most ToM scores. Patients poorer performance on executive tasks did not fully explain ToM differences between patients and controls, suggesting a partially selective ToM deficit in BPD. CONCLUSIONS: Patients with BPD are impaired in ToM, partially independent of other cognitive dysfunctions and current mood.

Alexithymia, emotion processing and social anxiety in adults with ADHD.

OBJECTIVE: given sparse research on the issue, this study sought to shed light upon the interactions of alexithymia, emotion processing, and social anxiety in adults with attention-deficit hyperactivity disorder (ADHD). SUBJECTS AND METHODS: 73 German adults with ADHD according to DSM-IV diagnostic criteria participated. We used the Toronto Alexithymia Scale (TAS-20) to assess alexithymia, the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS) to assess different features of social anxiety, and we applied the German "Experience of Emotions Scalerdquor; (SEE) to measure emotion processing. RESULTS: 40% of the sample were found to meet the DSM-IV criteria of social anxiety disorder, and about 22% were highly alexithymic according to a TAS-20 total score ≥ 61; however, the mean TAS-20 total score of 50.94 ± 9.3 was not much higher than in community samples. Alexithymic traits emerged to be closely linked to emotion processing problems, particularly 'difficulty accepting own emotions', and to social anxiety features. DISCUSSION/CONCLUSION: our findings suggest interactions of alexithymia, emotion processing dysfunction, and social anxiety in adults with ADHD, which may entail the therapeutic implication to thoroughly instruct these patients to identify, accept, communicate, and regulate their emotions to aid reducing interaction anxiety.

Serotonergic neurotransmission in early Parkinson's disease: a pilot study to assess implications for depression in this disorder.

OBJECTIVES: Depression, a disease usually accompanied by a serotonergic deficit, has been observed in about 40% of patients suffering from Parkinson's disease (PD). Thus, a serotonergic dysfunction in PD can be assumed. We aimed to investigate the interaction between serotonergic (5-HT) and dopaminergic activity in early PD. We hypothesized a serotonergic as well as a dopaminergic deficit in PD patients. We also assumed a correlation between these neurotransmitters indicating a relationship between dopaminergic and serotonergic function in PD. METHODS: Nine unmedicated PD patients before and 12 weeks after L-dopa treatment and nine healthy subjects were examined using the loudness dependence of auditory evoked potentials (LDAEP), a promising indicator of central serotonergic function. Dopaminergic transporters (DAT) were collected using (123)I-FP-CIT and single photon emission computer tomography (SPECT). LDAEP values were correlated with (123)I-FP-CIT SPECT data. RESULTS: A significant difference between LDAEP of controls and patients (P= 0.05) suggested lower serotonergic activity in PD. Twelve weeks after initiation of L-dopa treatment this difference was lost between patients and controls (P= 0.20). There was a trend towards a correlation between LDAEP and DAT (r= 0.65; P = 0.057) of the unmedicated patients, suggesting a low serotonergic activity may be related to a dopamine deficit in PD. CONCLUSIONS: Our results support the hypothesis that serotonergic neurotransmission is decreased in untreated PD and suggest that a low serotonergic activity may be related to the dopamine pathology in PD. This could be related to the high prevalence of depression in PD.

Cognitive impairment in patients with a schizoaffective disorder: a comparison with bipolar patients in euthymia.

OBJECTIVES: Several studies have shown persistent neurocognitive impairment in patients with a bipolar affective disorder (BD) even in euthymia as well as in patients with a schizoaffective disorder (SAD). The aim of our study was to compare the neuropsychological performance between these two groups. Confounding variables were controlled to enhance our understanding of cognitive dysfunction in both BD and SAD. METHODS: Several domains of neurocognitive function, executive function, memory, attention, concentration and perceptuomotor function were examined in 28 euthymic SAD patients and 32 BD patients by using a neuropsychological test battery. The Hamilton Depression Rating Scale (HAMD), Montgomery-Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS) were used to evaluate the patients' clinical status. Data analysis was performed by using a multivariate analysis of covariance (ANCOVA/MANCOVA). RESULTS: Euthymic SAD patients showed greater cognitive impairment than euthymic BD patients in the tested domains including declarative memory and attention. Putative significant group differences concerning cognitive flexibility vanished when controlled for demographic and clinical variables. Age and medication were robust predictors to cognitive performance of both SAD and BD patients. CONCLUSIONS: Our results point out the worse cognitive outcome of SAD compared to BD patients in remission. Remarkably, the variance is higher for some of the test results between the groups than within each group, this being discussed in light of the contradictive concept of SAD.
