Severity of alcohol dependence and mortality after 20 years in an adult general population sample The aim of the study was to estimate mortality on grounds of the severity of alcohol dependence which has been assessed by two approaches: the frequency of alcohol dependence symptoms (FADS) and the number of alcohol dependence criteria (NADC). A …
Pronounced Orthostatic Hypotension in GBA-Related Parkinson’s Disease Patients with Parkinson’s disease (PD) carrying variants in the Glucocerebrosidase (GBA) gene (GBA-PD) suffer from orthostatic symptoms more frequently than idiopathic PD patients (IPD). Systematic measurements of the blood pressure have not yet been performed. In the present study, a prospective analysis of 33 GBA-PD and 313 IPD …

Our new publication on “Characterizing thalamocortical (dys)connectivity following d-amphetamine, LSD, and MDMA administration” (Avram et al., 2022) in Biological Psychiatry CNNI shows that prototypical psychostimulants, empathogens, and psychedelics evoke thalamocortical-hyperconnectivity with sensorimotor areas, similar to findings in patients with psychosis, but differentially influence thalamocortical-connectivity with prefrontal-limbic cortices. Check out the publication here: Avram, M., Müller, …

Abstract Background: Fatigue has an adaptive function and serves as a temporary signal to rest and save energy often in response to immune activation. It may, however, also persist in a pathological condition incurring significant burden. While subjective symptoms and scientific consensus indicate that both physical and mental determinants of motivated behavior are affected in fatigue, …
Abstract To investigate the longitudinal latent state-trait structure of the different dimensions of psychosis symptoms in clinical high-risk state (CHRS) and first episode psychosis (FEP) individuals over a one year time-span. This paper examines if the symptom clusters Positive Symptoms, Negative Symptoms, Affectivity, Resistance, Activation, and Excitement according to the Brief Psychiatric Rating Scale (BPRS) …
Abstract Schizophrenia has a heritability of 60-80%1, much of which is attributable to common risk alleles. Here, in a two-stage genome-wide association study of up to 76,755 individuals with schizophrenia and 243,649 control individuals, we report common variant associations at 287 distinct genomic loci. Associations were concentrated in genes that are expressed in excitatory and …

New publication in Journal of Behavioral Addictions with contribution by Hans-Jürgen Rumpf! Abstract Background and aims: With the inclusion of gaming disorder in the ICD-11, diagnostic criteria were introduced for this relatively new disorder. These criteria may also be applied to other potential specific Internet-use disorders, which may be classified in ICD-11 as other disorders due …
Abstract Although abnormal resting state connectivity within several brain networks has been repeatedly reported in depression, little is known about connectivity in patients with early onset chronic depression. We compared resting state connectivity in a homogenous sample of 32 unmedicated patients with early onset chronic depression and 40 healthy control participants in a seed-to-voxel-analysis. According …

Abstract Aversive autobiographical memories play a key role in the development and maintenance of many mental disorders. Imagery rescripting is a well-established psychotherapeutic intervention aiming to create a more adaptive version of an aversive memory by modifying its interpretation. Sleep has been shown to support reconsolidation of updated neutral memories. Here, we investigated in healthy …

New publication in Neuropsychopharmacology with contribution by Rebekka Lencer! Abstract Some patients with schizophrenia have severe cognitive impairment and functional deficits that require long-term institutional care. The patterns of brain-behavior alterations in these individuals, and their differences from patients living successfully in the community, remain poorly understood. Previous cognition-based studies for stratifying schizophrenia patients highlight the …
