Performance on Cognitive Screening Tests and Long-Term Substance Use Outcomes in Patients with Polysubstance Use Disorder
(Journal article; Peer reviewed, 2023)Introduction: Cognitive impairments among patients with substance use disorders are prevalent and associated with adverse treatment outcomes. However, knowledge of the predictive value of broad cognitive screening instruments ... -
Social exclusion evokes different psychophysiological responses in individuals high on the psychopathy facets fearless dominance and self-centered impulsivity
(Journal article; Peer reviewed, 2024)Individuals with psychopathic personality traits are generally thought to have difficulties in processing and experiencing emotions. These difficulties could also translate to emotionally charged social situations such as ... -
The intra-individual reliability of 1H-MRS measurement in the anterior cingulate cortex across 1 year
(Journal article; Peer reviewed, 2024)Magnetic resonance spectroscopy (MRS) is the primary method that can measure the levels of metabolites in the brain in vivo. To achieve its potential in clinical usage, the reliability of the measurement requires further ... -
Estradiol driven change in hallucination proneness across the menstrual cycle as studied with a white noise paradigm
(Journal article; Peer reviewed, 2023)The estrogen hypothesis for schizophrenia suggests neuroprotective effects of estrogen for the development of the disorder and for symptom severity, including auditory hallucinations. Furthermore, estrogen has shown enhancing ... -
Cognitive function in patients with irritable bowel syndrome: impairment is common and only weakly correlated with depression/anxiety and severity of gastrointestinal symptoms
(Journal article; Peer reviewed, 2024)Objective To investigate cognitive function in patients with irritable bowel syndrome (IBS) and its relation to anxiety/depression and severity of gastrointestinal (GI) symptoms. Methods Patients with IBS (n = 65) ... -
High levels of childhood trauma associated with changes in hippocampal functional activity and connectivity in young adults during novelty salience
(Journal article; Peer reviewed, 2023)Childhood trauma (CT) has been linked to increased risk for psychosis. Moreover, CT has been linked to psychosis phenotypes such as impaired cognitive and sensory functions involved in the detection of novel sensory stimuli. ... -
Silver linings of ADHD: A thematic analysis of adults' positive experiences with living with ADHD
(Journal article; Peer reviewed, 2023)Objectives To identify and explore positive aspects of attention deficit hyperactivity disorder (ADHD) as reported by adults with the diagnosis. Design The current study used a qualitative survey design including the ... -
A psychological symptom based machine learning model for clinical evaluation of irritable bowel syndrome
(Journal article; Peer reviewed, 2023)Background: Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by recurrent abdominal pain associated with alterations in stool form and/or stool frequency. Co-morbidities such ... -
Investigating executive functions as a target for psychological interventions in ADHD: : Exemplified through the use of Goal Management Training
(Doctoral thesis, 2024-02-02)Bakgrunn Attention-deficit/hyperactivity disorder (ADHD) er en hyppig forekommende, og ofte livslang, tilstand som kan føre til vansker på mange områder. De som er rammet vil ofte oppleve negative utfall knyttet til ... -
Music for autism: a protocol for an international randomized crossover trial on music therapy for children with autism

Antidepressant mechanisms of ketamine: a review of actions with relevance to treatment-resistance and neuroprogression
(Journal article; Peer reviewed, 2023)Concurrent with recent insights into the neuroprogressive nature of depression, ketamine shows promise in interfering with several neuroprogressive factors, and has been suggested to reverse neuropathological patterns seen ... -
Efficient Brain Age Prediction from 3D MRI Volumes Using 2D Projections
(Journal article; Peer reviewed, 2023)Using 3D CNNs on high-resolution medical volumes is very computationally demanding, especially for large datasets like UK Biobank, which aims to scan 100,000 subjects. Here, we demonstrate that using 2D CNNs on a few 2D ... -
Long-term outcomes of an internet-delivered cognitive enhancement intervention targeting residual cognitive deficits after major depressive disorder: a 2-year follow-up of an open trial
(Journal article; Peer reviewed, 2023)Background: Cognitive deficits are common and disabling residual symptoms following major depressive disorder (MDD) and are related to increased risk of relapse. Residual cognitive deficits should thus be considered an ... -
