Stability of exercise addiction symptoms and co-occurring mental disorders – a follow-up study
This data suggests that EA is a temporary stable and distinct disorder with affected individuals suffering from severe psychological distress. Further studies are necessary to investigate potential cause-effect relationships between co-occurring mental disorders and EA
Brain alterations in individuals with exercise dependence: A multimodal neuroimaging investigation
Elucidating gut microbiota–hippocampus interactions in emerging psychosis: A new perspective for the development of early interventions for memory impairments
Hippocampal dysregulation might be a key pathophysiological factor for memory impairments in psychosis. Contemporary models particularly postulate that an imbalance of hippocampal glutamate and GABA leads to impaired memory and may thus serve as a therapeutic target to improve memory deficits. However, currently available interventions in early stages of psychosis do not explicitly target hippocampal pathology. A novel approach for manipulating h…
The heterogeneity of attenuated and brief limited psychotic symptoms: Association of contents with age, sex, country, religion, comorbidities, and functioning
Psychosis-risk patients report a wide range of different contents of APS/BIPS, underlining the psychopathological heterogeneity of this group but also revealing a potential core set of contents. Compared to earlier reports on North-American samples, our maximum prevalence rates of contents were considerably lower; this likely being related to a stricter rating of APS/BIPS and cultural influences, in particular, higher schizotypy reported in North…
Fecal Microbiota Transplantation (FMT) as an Adjunctive Therapy for Depression—Case Report
Depression is a debilitating disorder, and at least one third of patients do not respond to therapy. Associations between gut microbiota and depression have been observed in recent years, opening novel treatment avenues. Here, we present the first two patients with major depressive disorder ever treated with fecal microbiota transplantation as add-on therapy. Both improved their depressive symptoms 4 weeks after the transplantation. Effects laste…
Individuals at Risk of Exercise Addiction Have Higher Scores for Depression, ADHD, and Childhood Trauma
BackgroundExercise addiction is increasingly being recognized as a psychologically and physically burdensome set of symptoms. However, little is known about the psychiatric profiles of individuals who are at risk. It is well-established that individuals affected by substance use disorders frequently suffer from depression, attention deficit hyperactivity disorder (ADHD), and experiences of childhood trauma. The aim of this study is to determine w…
Mental Disorders in Individuals With Exercise Addiction—A Cross-Sectional Study
Background and Aims: Exercise addiction has not yet been designated as an addictive disorder in the DSM-5 due to a lack of detailed research. In particular, associations with other psychiatric diagnoses have received little attention. In this study, individuals with a possible exercise addiction are clinically assessed, in order to establish a profile of co-occurring psychiatric disorders in individuals with exercise addiction. Methods: One hundr…
Excessive Exercise—A Meta-Review
Background and Aims: While a number of studies have reported on individuals who exercise excessively, and feel unable to stop despite negative consequences, there is still insufficient evidence to categorize exercise as an addictive disorder. The aim of this meta-review is to summarize the published articles and to compile a list of symptoms reported in the qualitative literature in conjunction with excessive exercise. This list is compared with …
Insights From Setting up the First Wave of a Qualitative Longitudinal Study
In this paper we describe and reflect upon the process of setting up the first wave of a complex qualitative longitudinal study with young people in Vienna. We explain the project's agenda, design, and organizational structure connecting experienced and early career researchers with master's students. In particular, we describe the tools used to coordinate the research, the challenges and benefits of blending research and teaching, and the materi…
Cross-Validation of Paranoid-Depressive Scale and Functional MRI: New Paradigm for Neuroscience Informed Clinical Psychopathology
There is reported a study performed with a novel paradigm aiming at investigation of the translational validity of von Zerssen's paranoid-depression scale and its fMRI correlates in terms of focus on exploration of the results on the contrast between the Paranoid Specific (DP) blocks and the Depression Specific (DS) blocks. Patients with schizophrenia demonstrated significant activations in a number of regions (right angular gyrus, left posterior…
Impact of training in Advanced Cardiac Life Support (ACLS) in the professional career and work environment
We sought to evaluate the impact of Advanced Cardiac Life Support (ACLS) training in the professional career and work environment of physicians who took the course in a single center certified by the American Heart Association (AHA). Of the 4631 students (since 1999 to 2009), 2776 were located, 657 letters were returned, with 388 excluded from the analysis for being returned lacking addressees. The final study population was composed of 269 parti…
Acute Effects of Glucose and Fructose Administration on the Neural Correlates of Cognitive Functioning in Healthy Subjects: A Pilot Study
The present randomized double-blinded cross-over study aims to extensively study the neural correlates underpinning cognitive functions in healthy subjects after acute glucose and fructose administration, using an integrative multimodal neuroimaging approach. Five minutes after glucose, fructose, or placebo administration through a nasogastric tube, 12 participants underwent 3 complementary neuroimaging techniques: 2 task-based functional magneti…
Altered Insular Function during Aberrant Salience Processing in Relation to the Severity of Psychotic Symptoms
There is strong evidence for abnormal salience processing in patients with psychotic experiences. In particular, there are indications that the degree of aberrant salience processing increases with the severity of positive symptoms. The aim of the present study was to elucidate this relationship by means of brain imaging. Functional magnetic resonance imaging was acquired to assess hemodynamic responses during the Salience Attribution Test, a par…

Association of Frontal Gray Matter Volume and Cerebral Perfusion in Heroin Addiction: A Multimodal Neuroimaging Study
Structure and function are closely related in the healthy human brain. In patients with chronic heroin exposure, brain imaging studies have identified long-lasting changes in gray matter (GM) volume. More recently, we showed that acute application of heroin in dependent patients results in hypoperfusion of fronto-temporal areas compared with the placebo condition. However, the relationship between structural and cerebral blood flow (CBF) changes …
