Investigating genetic modulation of emotion processing may contribute to the understanding of heritable mechanisms of emotional disorders. The aim of the present study was to test the effects of catechol-O-methyltransferase (COMT) val158met and serotonin-transporter-linked promoter region (5-HTTLPR) polymorphisms on facial emotion processing in healthy individuals.

Two hundred and seventy five (167 female) participants were asked to complete a computerized facial affect recognition task, which involved four experimental conditions, each containing one type of emotional face (fearful, angry, sad or happy) intermixed with neutral faces. Participants were asked to indicate whether the face displayed an emotion or was neutral. The COMT-val158met and 5-HTTLPR polymorphisms were genotyped.

Met homozygotes (COMT) showed a stronger bias to perceive neutral faces as expressions of anger, compared with val homozygotes. However, the S-homozygotes (5-HTTLPR) showed a reduced bias to perceive neutral faces as expressions of happiness, compared to L-homozygotes. No interaction between 5-HTTLPR and COMT was found.

These results add to the knowledge of individual differences in social cognition that are modulated via serotonergic and dopaminergic systems. This potentially could contribute to the understanding of the mechanisms of susceptibility to emotional disorders.

22q11.2 deletion syndrome (22q11.2DS) and Williams syndrome (WS) are common neurogenetic microdeletion syndromes. The aim of the present study was to compare the neuropsychiatric and neurocognitive phenotypes of 22q11.2DS and WS.

Forty-five individuals with 22q11.2DS, 24 with WS, 22 with idiopathic developmental disability (DD) and 22 typically developing (TD) controls were compared for the rates of psychiatric disorders as well as cognitive executive and visuospatial functions.

We found that while anxiety, mood and disruptive disorders had an equally high prevalence among individuals with 22q11.2DS, WS and DDs, the 22q11.2DS group had the highest rates of psychotic disorders and the WS group had the highest rates of specific phobia. We also found that the WS group demonstrated more severe impairments in both executive and visuospatial functions than the other groups. WS and 22q11.2DS subjects had worse Performance-IQ than Verbal-IQ, a feature typical of non-verbal learning disorders.

These findings offer a wide perspective on unique versus common phenotypes in 22q11.2DS and WS.

We evaluate for the first time the associations of brain white matter hyperintensities (WMHs) on magnetic resonance imaging (MRI) with neuropsychological variables among middle-aged bipolar I (BPI), II (BPII) and major depressive disorder (MDD) patients and controls using a path model.

Thirteen BPI, 15 BPII, 16 MDD patients, and 21 controls underwent brain MRI and a neuropsychological examination. Two experienced neuroradiologists evaluated WMHs on the MRI scans. We constructed structural equation models to test the strength of the associations between deep WMH (DWMH) grade, neuropsychological performance and diagnostic group.

Belonging in the BPI group as opposed to the control group predicted higher DWMH grade (coefficient estimate 1.13, P = 0.012). The DWMH grade independently predicted worse performance on the Visual Span Forward test (coefficient estimate −0.48, P = 0.002). Group effects of BPI and MDD were significant in predicting poorer performance on the Digit Symbol test (coefficient estimate −5.57, P = 0.016 and coefficient estimate −5.66, P = 0.034, respectively).

Because of the small number of study subjects in groups, the negative results must be considered with caution.

Only BPI patients had an increased risk for DWMHs. DWMHs were independently associated with deficits in visual attention.

Adjustment disorder with anxiety (AjD-A) is a common cause of severe anxiety symptoms, but little is known about its prevalence in old age.

This cross-sectional study examined the prevalence of AjD-A in outpatients over the age of 60 who consecutively consulted 34 general practitioners and 22 psychiatrists during a 2-week period. The diagnosis of AjD-A was obtained using the optional module for diagnostic of adjustment disorder of the Mini International Neuropsychiatric Interview (MINI). The study procedure also explored comorbid psychiatric conditions and documented recent past stressful life events, as well as social disability and current pharmacological and non-pharmacological management.

Overall, 3651 consecutive subjects were screened (2937 in primary care and 714 in mental health care). The prevalence rate of AjD-A was 3.7% (n = 136). Up to 39% (n = 53) of AjD-A subjects had a comorbid psychiatric condition, mostly of the anxious type. The most frequently stressful life event reported to be associated with the onset of AjD-A was personal illness or health problem (29%). More than 50% of the AjD-A patients were markedly to extremely disabled by their symptoms. Compared to patients who consulted psychiatrists, patients who were seen by primary care physicians were older, had obtained lower scores at the Hamilton Anxiety Rating Scale, benefited less frequently from non-pharmacological management and received benzodiazepines more frequently.

AjD-A appears to be a significantly disabling cause of anxiety symptoms in community dwelling elderly persons, in particular those presenting personal health related problems. Improvement of early diagnosis and non-pharmacological management of AjD-A would contribute to limit risks of benzodiazepine overuse, particularly in primary care settings.

Increased levels of anxiety, depression and alcohol abuse are associated with unemployment. This study compares both DSM-IV-TR Axis-I and Axis-II mental disorders between a representative and a referred sample of unemployed youths aged 16.0 to 24.9.

One hundred subjects were randomly recruited on the premises of the vocational services centre in the urban region of Essen, Germany (representative sample, RS). One hundred and sixty-five subjects constituting the ‘clinical sample’ (CS) were preselected and referred by case managers to the on-site psychiatric liaison service. Structured Clinical Interviews for DSM-IV (SCID-I and -II), measures of psychopathology and health service utilization were administered.

Ninety-eight percent and 43% of CS and RS subjects fulfilled DSM-IV criteria for mental disorders. Mood-, anxiety- and substance-related disorders were the most common Axis-I disorders in both samples. Personality disorders were diagnosed significantly more frequently in the CS. Despite the more severe psychopathology in subjects with mental disorders from the CS compared to the RS, no differences were found for recent mental health service utilisation.

Because the sample of unemployed youths referred by case managers was significantly more disturbed in psychiatric terms, such a pre-selection is deemed useful in conjunction with a psychiatric liaison service on the premise of a job centre.

Few studies have examined rate and predictors of self-harm in discharged psychiatric patients.

To investigate the rate, coding, timing, predictors and characteristics of self-harm induced somatic admission after discharge from psychiatric acute admission.

Cohort study of 2827 unselected patients consecutively admitted to a psychiatric acute ward during three years. Mean observation period was 2.3 years. Combined register linkage and manual data examination. Cox regression was used to investigate covariates for time to somatic admission due to self-harm, with covariates changing during follow-up entered time dependently.

During the observation period, 10.5% of the patients had 792 somatic self-harm admissions. Strongest risk factors were psychiatric admission due to non-suicidal self-harm, suicide attempt and suicide ideation. The risk was increased throughout the first year of follow-up, during readmission, with increasing outpatient consultations and in patients diagnosed with recurrent depression, personality disorders, substance use disorders and anxiety/stress-related disorders. Only 49% of the somatic self-harm admissions were given hospital self-harm diagnosis.

Self-harm induced somatic admissions were highly prevalent during the first year after discharge from acute psychiatric admission. Underdiagnosing of self-harm in relation to somatic self-harm admissions may cause incorrect follow-up treatments and unreliable register data.

Depression and acute coronary syndrome (ACS) are both extremely prevalent diseases. Studies aimed at evaluating whether depression is an independent risk factor for cardiac events provided no definitive results. In most of these studies, depression has been broadly defined with no differentiation between unipolar (MDD) versus bipolar forms (BD). The aim of this study was to evaluate the frequency of DSM-IV BD (bipolar I and bipolar II subtypes, cyclothymia), as well as temperamental or isolated bipolar features in a sample of 171 patients hospitalized for ACS. We also explored whether these psychopathological conditions were associated with some clinical characteristics of ACS.

Patients with ACS admitted to three neighboring Cardiac Intensive Care Units (CICUs) in a 12-month continuative period of time were eligible for inclusion if they met the criteria for either acute myocardial infarct with or without ST-segment elevation or unstable angina, verified by standard ACS criteria. All patients underwent standardized cardiological and psychopathological evaluations.

Of the 171 ACS patients enrolled, 37 patients (21.7%) were found to have a DSM-IV mood disorder. Of these, 20 (11.7%) had bipolar type I or type II or cyclothymia, while 17 (10%) were the cases of MDD. Rapid mood switches ranged from 11% of ACS patients with no mood disorders, to 47% of those with MDD to 55% of those with BD. Linear regression analysis showed that a diagnosis of BD (p = .023), but not that of MDD (p = .721), was associated with a significant younger age at the index episode of ACS. A history of previous coronary events was more frequent in ACS patients with BD than in those with MDD.

Our data indicate that bipolar features and diagnosis are frequent in ACS patients. Bipolar disorder has a negative impact on cardiac symptomatology. Further research in this area is warranted.

To estimate the risk of schizophrenia in adulthood among children and adolescents with ADHD compared to the background population.

Two hundred and eight youths with ADHD (183 boys; 25 girls) were followed prospectively. Diagnoses of schizophrenia were obtained from The Danish Psychiatric Central Register. The relative risk (RR) of schizophrenia for cases with ADHD, compared to the normal population, was calculated as risk ratios. Hazard ratios (HR's) by Cox regression were calculated in the predictor analyses.

Mean age for ADHD cases at follow-up was 31.1 years. Schizophrenia diagnoses were given to 3.8% of these cases. Compared to the general population, RR of schizophrenia in cases with ADHD was 4.3 (95% CI 1.9–8.57).

This prospective follow-up study found children with ADHD to be at higher risk of later schizophrenia than controls. If replicated, these results warrant increased focus on the possible emergence symptoms of schizophrenia or schizophreniform psychosis during clinical follow-up of patients with ADHD.
