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
(Journal article; Peer reviewed, 2023)The notion of a connection between autism and music is as old as the first reported cases of autism, and music has been used as a therapeutic tool for many decades. Music therapy holds promise as an intervention for ... -
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 ... -
GABA, glutamatergic dynamics and BOLD contrast assessed concurrently using functional MRS during a cognitive task
(Journal article; Peer reviewed, 2023)A recurring issue in functional neuroimaging is how to link task-driven haemodynamic blood oxygen level dependent functional MRI (BOLD-fMRI) responses to underlying neurochemistry at the synaptic level. Glutamate and ... -
Towards a multilevel model of major depression: genes, immuno-metabolic function, and cortico-striatal signaling
(Journal article; Peer reviewed, 2023)Biological assay and imaging techniques have made visible a great deal of the machinery of mental illness. Over fifty years of investigation of mood disorders using these technologies has identified several biological ... -
Performance on the balloon analogue risk task and anticipatory response inhibition task is associated with severity of impulse control behaviours in people with Parkinson’s disease
(Journal article; Peer reviewed, 2023)Dopamine agonist medication is one of the largest risk factors for development of problematic impulse control behaviours (ICBs) in people with Parkinson’s disease. The present study investigated the potential of dopamine ... -
Assessment of Self-Reported Executive Function in Patients with Irritable Bowel Syndrome Using a Machine-Learning Framework
(Journal article; Peer reviewed, 2023)Introduction: Irritable bowel syndrome (IBS) is characterized as a disorder of the gut–brain interaction (DGBI). Here, we explored the presence of problems related to executive function (EF) in patients with IBS and tested ... -
Social and non-social feedback stimuli lead to comparable levels of reward learning and reward responsiveness in an online probabilistic reward task
(Journal article; Peer reviewed, 2023)Social stimuli seem to be processed more easily and efficiently than non-social stimuli. The current study tested whether social feedback stimuli improve reward learning in a probabilistic reward task (PRT), in which one ... -
Sensorimotor synchronization to music reduces pain
(Journal article; Peer reviewed, 2023-07-28)Pain-reducing effects of music listening are well-established, but the effects are small and their clinical relevance questionable. Recent theoretical advances, however, have proposed that synchronizing to music, such as ... -
Ghrelin is related to lower brain reward activation during touch
(Journal article; Peer reviewed, 2023)The gut hormone ghrelin drives food motivation and increases food intake, but it is also involved in the anticipation of and response to rewards other than food. This pre-registered study investigated how naturally varying ... -
