Epigenetic Enhancement of Cognitive Training in Aging Mood Disorder Populations
Sponsor: Mental Health Centre Copenhagen, Bispebjerg and Frederiksberg Hospital
Summary
The aim of this clinical trial is to investigate the effects of a three-week virtual reality-based cognitive remediation training (VR-CRT) programme in combination with daily intake of a histone deacetylase inhibitor (HDACi) sodium butyrate on cognition in symptomatically stable patients with mood disorders (depression or bipolar disorder). The investigators hypothesize that the VR-based cognitive remediation training (VR-CRT) combined with HDACi butyrate vs. a VR-based control treatment combined with placebo will improve global cognition (primary outcome measure) over three weeks. Secondly, the investigators hypothesize that VR-CRT with placebo will improve cognition relative to the VR control treatment with placebo, although to a lesser extent than VR-CRT with HDACi butyrate. Thirdly, the investigators hypothesize that the HDACi butyrate with VR control treatment will not produce cognitive improvements relative to placebo with VR control treatment. Finally, the investigators hypothesize that the combined treatment (VR-CRT + HDACi butyrate) will enhance neuroplasticity (exploratory outcome) vs. VR control with placebo, as indicated by increase in hippocampal volume and/or memory-related activity shown with structural and functional MRI.

Interventions
Virtual Reality-based cognitive remediation therapy (VR-CRT)
VR-CRT on 360° Meta Quest 2-software in which participants train cognitive abilities guided by a therapist. The platform includes three immersive scenarios: (1) a kitchen scenario focusing on planning and cooking a meal, (2) a supermarket scenario focusing on grocery shopping and (3) a restaurant scenario focusing on remembering names and personal information. The virtual reality training is supported by a psychoeducation program that focuses on application of learned cognitive strategies in daily life.
Virtual Reality-based control treatment (VR-CT)
VR-CT: The virtual reality control training involves completing different virtual reality games that are available through the Meta Quest games store. The chosen games involve no direct training of cognitive abilities such as planning skills og strategic learning, but merely involves simple reaction time and interaction with an entertaining environment that is meaningful to the participant and gives the impression of training cognitive skills.
HDACi butyrate
Daily intake of sodium butyrate.
Placebo
Daily intake of placebo.
