Increasing evidence suggests that symptoms of Attention Deficit Hyperactivity disorder (ADHD) could persist into adult life in a substantial proportion of cases. The aim of the present study is to investigate the impact of 1) adverse events, 2) personality traits and 3) genetic variants chosen on the basis of previous findings and 4) their possible interactions on adult ADHD severity in a sample of 110 Caucasian patients.

One hundred and ten individuals diagnosed with adult ADHD were evaluated for occurrence of adverse events in childhood and adulthood, and personality traits by the Temperament and Character Inventory (TCI). Common polymorphisms within a set of nine important candidate genes (SLC6A3, DBH, DRD4, DRD5, HTR2A, CHRNA7, BDNF, PRKG1 and TAAR9) were genotyped for each subject. Life events, personality traits and genetic variations were analyzed in relationship to severity of current symptoms, evaluated by the Brown Attention Deficit Disorder Scale (BADDS).

Genetic variations were not significantly associated with severity of ADHD symptoms and life stressors displayed only a minor effect as compared to personality traits. Indeed, symptoms’ severity was significantly correlated with the temperamental trait of Harm avoidance and the character trait of Self directedness.

The results of the present work are in line with previous evidence of a significant correlation between some personality traits and adult ADHD. However, several limitations such as the small sample size and the exclusion of patients with other severe comorbid psychiatric disorders could have influenced the significance of present findings.

Low platelet MAO-B activity has been associated with various forms of impulsive behaviour and suicidality. The present study investigated the relationship between MAO-B activity in platelets and aspects of suicidality in depressed patients and controls.

In 87 patients with affective spectrum disorders (58% suffering from a Major Depressive Episode - MDE) the potential association between platelet MAO-B activity and suicidality was examined. 59 of the patients had committed suicide attempt recently (SA - “suicide attempters”), 28 patients were acutely depressed without having shown suicidal thoughts or suicidal behaviour in the past (NA - “non suicide attempters”).

SA and NA were comparable as to their diagnoses and general demographic and psychopathological parameters. MAO-B activity did not differ between SA and NA. No systematic correlations existed between MAO-B activity and any dimensions of suicidal behaviour or psychopathology. As a single finding only a weak positive association of higher MAO-B activity in SA with a fatal intention of the suicide attempt was observed.

Our findings do not support a consistent association of platelet MAO-B activity and suicidal behaviour in general, but specific facts of suicidality might be associated.

ADHD is a well-established neurodevelopmental disorder affecting a significant population across the lifespan. Driven by the need to provide adequate clinical care, several national and international medical societies have published guidelines on ADHD. Our objectives were to compare the recommendations set out by these guidelines and their methodological quality.

To meet the inclusion criteria the guidelines had to be published by national or international medical societies or governmental bodies and focus on diagnosis or management of ADHD. To assess their methodological quality we used the Appraisal of Guidelines for Research & Evaluation (AGREE) instrument.

We identified 13 guidelines on diagnosis and/or management of ADHD meeting our inclusion criteria. They represented the recommendations from 9 different bodies from 4 different countries and 1 European group. All guidelines made recommendations on both diagnosis and treatment. Seven made recommendations concerning children and adolescents, four are about ADHD in adulthood and two made brief comments on specific aspects of treatment in adulthood. All groups have used DSM-IV criteria but differed on their assessment recommendations to varying degrees. All of them recommended stimulants as the core of pharmacological treatment. Only one (NICE 2008) recommends specifically methylphenidate as the first-line treatment.

Most of the diagnostic and treatment recommendations are consistent across the guidelines with few but important exceptions. This may reflect differences of service provision and target audiences. Convergent recommendation of psychostimulant treatment and differences with respect to psychosocial interventions reflect the strength (and weakness) of underlying evidence.

Atomoxetine, a highly selective noradrenaline reuptake inhibitor, shows efficacy in the treatment of ADHD. Despite evidence that atomoxetine improved inhibitory control in animals and healthy volunteers, studies had yet to explore short-term cognitive effects in patients with ADHD.

The cognitive effects of a single oral dose of atomoxetine (60mg) were evaluated in n=22 adults with DSM-IV ADHD, using a within-subject placebo-controlled double-blind design. Assessment included the stop-signal test and Rapid Visual Information Processing test from the Cambridge Neuropsychological Test Automated Battery (CANTAB). Cardiovascular responses were monitored. Normative cognitive data from 20 healthy volunteers were collected for comparison.

Atomoxetine was associated with shorter stop-signal reaction times (p<0.05) and lower numbers of commission errors (p<0.05) on the sustained attention task in the ADHD patients.

These findings suggest that atomoxetine exerts beneficial effects on aspects of inhibitory control in ADHD, which may belie the efficacy of this medication in the treatment of impulsive features of the disorder. These findings also have potential clinical implications for other impulse dysregulation disorders such as trichotillomania and Tourette's Syndrome.

Internet Addiction (IA) is discussed as a serious health problem. Epidemiologic investigations show prevalence rates of 3% of internet users that fulfil criteria for IA. Reported symptoms like tolerance, withdrawal, and craving resemble those of substance-related disorders. Although there is no final agreement on the classification of IA, it has often been referred to as a non-substance-related addiction fostering current issues on the next revision of DSM (Holden, 2010).

Although IA has been investigated in epidemiologic studies there is no research of its prevalence in patients in treatment because of a substance-related disorder. Regarding similarities between IA and substance-related disorders, theories suggest increased prevalence of comorbid IA in these patients.

This study focused on the identification of prevalence of comorbid IA among patients with a primary substance-related disorder in different in-patient clinics across Germany.

Sponsored by the German Federal Ministry of Health 1826 patients were screened with a diagnostic inventory for IA. For further description additional questionnaires were given assessing aspects of personality (NEO-FFI) and psychopathology (SCL-90R, BDI-II).

4.1% of the patients fulfilled criteria of IA. In these most common primary diagnoses were pathological gambling and dependency of cannabis. Concerning personality IA-subsample showed increased neuroticism and introversion. Highest symptom burden was found in depression and social insecurity.

Among patients with substance-related disorder prevalence of IA is more common than in healthy samples. Results recommend separate screening for IA in inpatient clinics for substance-related disorders to guarantee full psychological care for patients with IA.

26.5% of psychiatric patients in Germany have minor children. More than half of these children have specific needs, which are seldom met.

To examine problems, needs and used interventions for families with a mentally ill parent in the federal state of Saxony, Germany. The study focused on outpatients and included mothers and fathers and all psychiatric disorders.

We asked all psychiatrists in the federal state of Saxony to take part in our study. All patients with minor children who came to one of the 58 participating psychiatrist's practices at an appointed date were asked to fill out a detailed questionnaire including sociodemographic data, the Strengths and Difficulties Questionnaire (SDQ), specific needs, used interventions and reasons for not using interventions. The questionnaire was developed using data from 26 expert interviews.

128 psychiatric outpatients took part in our study (78% female). The most common diagnoses were depression and anxiety disorders. More than 40% of the patients rated their children in the SDQ in an abnormal or borderline range. 22% of the children have been treated because of emotional or behavioural problems. Reasons not to use interventions were missing knowledge and fear of stigmatisation.

HELP-S for children is the first study which examines the situation of children with a mentally ill parent in an outpatient setting. Therefore, our results are an improvement in research in the field of families with a mentally ill parent and heading towards the improvement of care.

Growing evidence suggests that soluble amyloid-beta (Abeta) peptides play a pivotal role in Alzheimer’s disease(AD) pathogenesis by mediating synaptotoxic effects particularly at early disease stages.

We quantified the effects of different order Abeta assemblies on spontaneous firing dynamics ofneuronal networks cultured on multielectrode arrays ('neurochips”) as a read-out. We used naturally secreted, stable and conformationally highly homogenous Abeta monomers, dimers, and a mixture of different low-noligomers, derived from permanently transfected cell lines.

Abeta dimers promoted a dose-dependent suppression of overall activity and network synchrony and altered the burst structure already in the low picomolar dose range. By contrast, Abeta monomers exhibited no effect on overall activity, but only a slight effect on burst structure and a moderate effect on network synchrony. A yet different response pattern was seen for a mixture of various low-n Abeta oligomers. Thus, multiparametric assessment of electrical activity changes on neurochips revealed characteristic signatures of the network response for the different Abeta assemblies. Since alterations of Network function likely occur in initial disease stages, these results confirm the pivotal role of Abeta dimers in early AD pathogenesis.

Neurochip recordings of toxic dimeric Abeta species may serve as a valuable diagnostic read-out in early AD and may also be applicable for future testing of drugs, antibodies, or small molecules aiming at Abeta dimers.

Transcranial direct current stimulation (tDCS) is currently discussed as a therapeutic intervention in various psychiatric disorders. Based on the report about the effectiveness of tDCS in a patient with catatonic schizophrenia, we applied bilateral prefrontal tDCS in a patient with corpus callosum aplasia (CCA) and severe catatonia instead of maintenance electroconvulsive therapy (ECT).

To investigate whether tDCS can replace ECT in a largely treatment-resistant patient.

The 41 year-old male patient showed severe catatonic symptoms since adolescence and was treated by weekly ECT for almost 6 years. Due to cardiac complications and increasing cognitive deficits caused by long-term ECT and weekly anesthesia, tDCS was suggested. The anode was positioned over the left dorsolateral prefrontal cortex (DLPFC), the cathode over the right DLPFC. 2mA tDCS was delivered for 2x 20 minutes (90 minutes break in between), three times a week for the first two weeks, thereafter once to twice weekly. Concomitant medication (clozapine 600 mg/d, aripiprazole 10 mg/d, pirenzepine 50 mg/d, lorazepam 3 mg/d) was continued.

So far, more than 20 double sessions of tDCS were applied. ECT was needed once after a period of hospitalisation for 10 days due to pneumonia. Since then the patient has solely received tDCS for more than 13 weeks. Catatonic symptoms resolved further under tDCS compared to ECT (Bush-Francis Catatonia Rating Scale: 27/69 points during ECT, 5/69 during tDCS).

tDCS in combination with neuroleptic treatment could be an alternative to ECT in organic catatonia. Further studies are needed to support our hypothesis.

Negative symptoms and cognitive impairments are both present in patients with an at risk mental state (ARMS) for psychosis and negatively affect functioning and outcome. According to previous studies in patients with first-episode psychosis, negative symptoms are negatively associated with cognitive functioning while positive symptoms do not seem to be associated. Yet, little is known about the specific relationship of negative symptoms and cognitive functioning in ARMS patients.

To evaluate, the relationship between negative symptoms and cognitive functioning in ARMS patients.

Data of 154 ARMS patients were collected within the prospective Basel early detection of psychosis (FePsy) study. Negative symptoms were assessed with the SANS, positive psychotic symptoms with the BPRS, cognitive functioning with an extensive neuropsychological test battery. Multiple regressions were applied and results were controlled for age and gender.

Regression analyses showed a significant, negative association between negative but not positive psychotic symptoms and cognitive functioning, showing the strongest association with verbal fluency (see Fig. 1). However, results mainly did not withstand correction for multiple testing.

The association found between verbal fluency and negative symptoms may be indicative of an overlap between those constructs. Finally, verbal fluency might have a strong influence on the clinical impression of negative symptoms, especially on alogia.

Non-psychotic axis I diagnoses are highly prevalent in at-risk mental state (ARMS) and first episode psychosis (FEP) patients, the most common being affective and anxiety disorders. Few studies have examined differences between ARMS and FEP patients or gender effects regarding such diagnoses.

To examine current and lifetime comorbidities in ARMS and FEP patients. Furthermore, to examine gender differences, and differences between patients with (ARMS-T) and without later transition to psychosis (ARMS-NT).

This study was part of the Früherkennung von Psychosen (FePsy) study. Current and lifetime axis I comorbidities were assessed using the Structured Clinical Interview for DSM-IV (SCID-I).

One hundred and thirty-two ARMS and 98 FEP patients were included. Current comorbidities were present in 53.1% of FEP and 64.4% of ARMS patients, the most common being affective, anxiety and substance use disorders. Current affective disorders were significantly more common in ARMS than FEP. Lifetime comorbidities were diagnosed in 58.2% of FEP and 69.7% of ARMS patients, with significantly more affective and anxiety disorders in ARMS than FEP. Male FEP patients had more current and lifetime substance use disorders (across all substances) compared to female FEP. No differences emerged between ARMS-T and ARMS-NT.

As expected ARMS patients have many comorbidities, while clearly diagnosed FEP have less comorbidities. There were few gender differences in axis I comorbidities. Moreover, no differences between ARMS-T and NT emerged, suggesting that axis I comorbidities do not improve prediction of transition. Nevertheless, the high comorbidity prevalence is relevant for global functioning and clinical treatment.

Gambling disorder is associated with various adverse effects. While data on the immediate effectiveness of treatment programs are available, follow-up studies examining long-term effects are scarce and factors contributing to a stable therapy outcome versus relapse are under-researched.

Patients (n = 270) finishing inpatient treatment for gambling disorder regularly participated in a prospective multicenter follow-up study (pre-treatment, post-treatment, 12-month follow-up). Criteria for gambling disorder, psychopathology, functional impairment were defined as endpoints. Changes in personality were defined as an additional parameter.

At follow-up, three groups were identified: subjects maintaining full abstinence (41.6%), patients still meeting criteria for gambling disorder (29.2%), and subjects still participating in gambling without meeting the diagnostic criteria for gambling disorder (29.2%). Every group had improvements in functional impairment, abstinent subjects showed the lowest psychopathology. Significant decreases in neuroticism and increases in both extraversion and conscientiousness were found among abstinent subjects but not in patients still meeting criteria for gambling disorder.

One year after treatment, a considerable percentage of patients kept on gambling but not all of them were classified with gambling disorder leading to the question if abstinence is a necessary goal for every patient.

The changes of personality in abstinent patients indicate that after surmounting gambling disorder a subsequent maturing of personality might be a protective factor against relapse.

Patients with a first episode psychosis (FEP) have repeatedly been shown to have gray matter (GM) volume alterations. Some of these neuroanatomical abnormalities are already evident in the at-risk mental state (ARMS) for psychosis. Not only GM alterations but also neurocognitive impairments predate the onset of frank psychosis with verbal learning and memory (VLM) being among the most impaired domains. Yet, their interconnection with alterations in GM volumes remains ambiguous.

To evaluate associations of different subcortical GM volumes in the medial temporal lobe with VLM performance in ARMS and FEP patients.

Data were collected within the prospective Früherkennung von Psychosen (FePsy) study, which aims to improve the early detection of psychosis. VLM was assessed using the California Verbal Learning Test (CVLT) and its latent variables Attention Span (AS), Learning Efficiency (LE), Delayed Memory (DM) and Inaccurate Memory (IM). Structural images were acquired using a 3 Tesla magnetic resonance imaging scanner.

Data from 59 ARMS and 47 FEP patients were analysed. Structural equation models revealed significant associations between the amygdala and AS, LE and IM; thalamus and LE and IM; and the caudate, hippocampus and putamen with IM. However, none of these significant results withstood correction for multiple testing.

Although VLM is among the most impaired cognitive domains in emerging psychosis, we could not find an association between low performance in this domain and reductions in subcortical GM volumes. Our results suggest that deficits in this domain may not stem from alterations in subcortical structures.

Clinical, epidemiological and basic research studies have confirmed that estradiol can have protective effects in schizophrenic psychoses. At the same time many patients with schizophrenic psychoses – even antipsychotic naïve at-risk mental state (ARMS) patients show hyperprolactinemia and gonadal dysfunction with estrogen deficiency in women and possibly testosterone deficiency in men.

To investigate the relation between the stress hormone prolactin and the sex hormones estradiol in women and testosterone in men in emerging psychosis.

Forty-seven antipsychotic-naïve ARMS (38 men and 9 women) and 17 antipsychotic-naive first episode psychosis (FEP) (14 men and 3 women) patients were recruited via the Basel Früherkennung von Psychosen (FePsy) study. Blood was taken under standardized conditions between 8 and 10 am after an overnight fast and 30 minutes of rest. We performed a linear regression model to evaluate the association between prolactin and sex hormones including age and current antidepressant use as covariates.

In women, estradiol was negatively associated with prolactin (β = −1.28, P = 0.01) whereas in men there was a positive association of testosterone with prolactin (β = 0.52, P = 0.031).

The often observed estrogen deficiency in women with psychosis could therefore be explained by the stress hormone prolactin suppressing the gonadal axis already in very early untreated stages of the emerging disease.

In ARMS or FEP men prolactin does not seem to influence the gonadal axis in the same way as in women.

In the growing research field of early psychosis detection in patients with an at risk mental state (ARMS), most studies focus on the transition to frank psychosis. However, the majority of ARMS patients do not go on to develop frank psychosis and reported transition rates are declining. Little is known about the long-term outcome of these non-transitioned patients (ARMS-NT).

To investigate in preliminary analyses the long-term outcome of ARMS-NT patients with respect to persistence of ARMS signs and symptoms and the rates of late psychotic transition.

The ongoing study “FePsy-BHS-NT” follows up ARMS-NT without transition during at least the first two years for up to 15 years after their initial assessment. ARMS status is ascertained with the Basel Screening Instrument for Psychosis (BSIP). ARMS remission is defined as the absence of attenuated psychotic symptoms or brief limited intermittent psychotic symptoms for at least 12 consecutive months.

In this preliminary sample of 51 ARMS-NT, the majority of patients (70.6%) have remitted from their at risk mental state, 13.7% remain at risk and 15.7% have made a late psychotic transition during the course of long-term follow up (median = 5.75, range 4–11 years after initial assessment).

The considerable rates of ARMS persistence and late psychotic transition indicate that longer follow-up durations than commonly recommended should be contemplated in ARMS patients. Potential predictors of favorable long-term clinical outcome, as well as psychosocial, neurocognitive and other outcomes of ARMS-NT patients will be further evaluated in the present study.
