Long title: Functional Magnetic Resonance Imaging signatures of depression and response to antidepressants in early psychosis

FSAREP is an observational study which tests the validity of a novel biomarker as predictor of response to antidepressants in those with Early Psychosis (EP) using functional magnetic resonance imaging (fMRI).
The first five years of psychosis are considered a critical period for intervening to improve long-term outcome. This critical period is usually referred to as EP. Around half of patients presenting with EP will develop depressive symptoms. Similarly, negative symptoms are highly prevalent (i.e. 51%) in EP and often run a chronic course. Crucially, negative and depressive symptom domains significantly overlap and at a phenomenological level are difficult to disentangle. Importantly, whilst antidepressants are efficacious in treating depressive symptoms, the evidence supporting their efficacy in the treatment of negative symptoms remains inconclusive. Hence, a detailed understanding of the neural mechanisms underlying these symptom domains in the context of EP has significant translational potential and will help guide effective treatment selection.
This study is led by NHS Greater Glasgow and Clyde and is financially supported by a SIM fellowship. A total of 65 participants will be recruited from ESTEEM or community mental health teams across NHS Greater Glasgow and Clyde.
The primary objectives of this study are – a) Prediction of response to Selective Serotonin Reuptake Inhibitor (SSRI) treatment at the individual level, and b) Identification of model-based fMRI biomarkers differentiating between negative and depressive symptoms in early psychosis (EP).
Participants who meet the eligibility criteria will attend a total of 3 visits comprising of clinical assessments (before and after each participant starts antidepressant treatment) and a single neuroimaging visit.
Visit 1 – 90 minutes
This will take place alongside a routine visit.
Scanning appointment at Centre for Cognitive Neuroimaging (CCNi), University of Glasgow will be booked.
Visit 2- 90 minutes:
A return taxi journey will be arranged for participants to attend the scanning visit at CCNi.
Visit 3 – 60 minutes:
After 6 weeks of treatment the research team will arrange to meet the participant in line with a routine visit.
Taxi fare for travel to scanning appointment will be paid and at the end of the study participants will receive a £20 Amazon voucher.
