Reseach Foci of the Division of General Psychiatry

  • Systematic and continuous assessment and documentation of side effects and adverse events occurring under psychopharmacologic treatment, as well as cross-sectional assessments of prescribing patterns. This focus is in cooperation with the Österreichische Gesellschaft für Arzneimittelsicherheit in der Psychiatrie (ÖAMSP)

  • Neuroimaging withPET, PET/MR, MRT, fMRT, MRS, SPECT, EEG
  • Quantification of levels of specific proteins in the brain (i.e., serotonin-1A-receptors, NMDA-receptors, dopamin-2/3-Receptors, monoamine transporters (SERT, NET), enzymes (MAOA) with PET in psychiatric disorders (i.e., depression, anxiety disorders, schizophrenia, ADHD) as well as treatment-induced changes.
  • Quantification of the occupancy of psychopharmaceuticals at specific targets in the brain and assessment of the association with functional changes (i.e., neuronal network alterations)
  • Quantification of glucose and neurotransmitter metabolism in the brain (i.e., with the radioligands FDOPA and FDG), also simultaneously with fMRI
  • Assessment of perfusion (pcASL) with PET/MR for differentiation of glucose metabolism and neuronal activity during cognitive or emotional tasks or psychopharmacological stimulation
  • Imaging genetics: assessment of the relationship between genetic variants, epigenetics (i.e., mRNA, methylome), and protein levels in various psychiatric disorders and in association with functional and structural changes
  • Assessment and testing of neuroimaging-based prediction parameters for treatment and early detection
  • Assessment and testing of neuroimaging-based prediction parameters for differential diagnostics and subgroup-classification
  • fMRI for the assessment of neuronal activation patterns in psychiatric disorders and in accordance with emotional and cognitive tasks
  • FMRI for the assessment of neuronal connectivity patterns in psychiatric disorders and specific therapies (i.e, psychopharmacology, TMS, ECT)
  • MRI for the quantification of glutamate/glutamine and GABA in various psychiatric disorders and in association with various treatments (i.e., ketamine, TMS, SSRIs)
  • Brain morphometry (voxel- and parcellation-based) including assessment of hippocampus substructures, amygdala, thalamus, brainstem, and cortex in the context of psychiatric disorders and treatment
  • Assessment of the glymphatic system during sleep and under psychopharmacologic treatment utilizing PET/MR/EEG

  • The study of light therapy and therapeutic sleep deprivation as non-pharmacologic biologic treatment measures
  • Chronobiologic characteristics of psychiatric disorders, particularly affective disorders
  • Seasonal affective disorder

  • Study of antidepressants (i.e., SSRIs and ketamine) utilizing a broad array of imaging methods (i.e., PET, MRS, fMRI…)
  • Treatment optimization in TMS using imaging-supported stimulation based on structural and functional data
  • Research on light therapy and therapeutic sleep deprivation using imaging (i.e., MAOA PET, fMRI)
  • Study of seasonal affective disorder using methods for the assessment of brain structure and protein concentrations

  • Research to support the definition of treatment response, non-response, and resistance
  • Research to support the definition of pseudo-resistance
  • Algorithms for antidepressant therapy
  • Psychopharmacotherapeutic strategies in non-response and resistance
  • Clinical and genetic correlates of non-response and resistance
  • Clinical and genetic correlates of „difficult-to-treat depression" (DTD)“
  • Research on the impact of socio-demographic factors and clinical variables on treatment response

  • Efficacy and tolerability of psychopharmaceuticals
  • Assessment of study methodology in psychopharmacologic studies with a focus on placebo response
  • Meta-Analyses

  • Genetic and epigenetic studies in various neuropsychiatric disorders including affective disorders, schizophrenia, Gilles de la Tourette Syndrome, eating disorders, etc.
  • Genetic and epigenetic studies in suicidality in affective disorders
  • Studies on gene-environment interaction
  • Pharmacogenetic studies on response and side effects in various psychiatric disorders

  • Treatment concepts
  • Assessment of the toxicity of pschopharmaceuticals
  • The study of involuntary admission and treatment in the context of the “Unterbringungsgesetz”
  • Treatment response and imaging of electroconvulsive therapy with PET/MR (serotonin-1A-receptors, MAO-A, volumetric analysis) and plasma markers (BDNF)

  • Assessment of new psychopharmaceuticals in regards to their efficacy and tolerability
  • Assessment of clinical and biological treatment markers
  • Assessment of the relationship between genetic variables, response, and tolerability
  • Assessment of challenging clinical phenomena and treatment resistance as well as treatment strategies

  • Impact of sensitization, schizophrenia, and genetic parameters on dopamine metabolism
  • Sex differences in dopamine metabolism in patients with schizophrenia and healthy controls
  • Structural characteristics of the cortex and their impact on dopamine release in schizophrenia, assessed with PET/MR
  • Impact of omega-3-fatty acids on dopamine metabolism and working memory in patients with first-episode psychosis, persons at high risk, and healthy controls
  • Assessment of amphetamine-induced sensitization on dopamine synthesis and release
  • Prediction studies in first-episode psychosis
  • Sex and gender aspects of auditory hallucinations in schizophrenic disorders
  • Translation and validation of the questionnaire „BAVQ-R"
  • Translation and validation of the questionnaire „VPD" (Voice Power Differential Scale)
  • The influence of ToM -disorders on reaching personal goals in patients with schizophrenia (Pilot study)

  • Studies on the diagnosis and treatment of substance use disorders and non-substance use disorders
  • Influence of somatic and psychiatric comorbidities on the course of substance use disorders
  • Treatment accessibility studies for substance use disorders in incarceration
  • Impact of opiate substitution therapy on intrauterine development
  • Hotline for patients with gambling addiction
