Abstract

While previous research has primarily examined the acute and sub-chronic effects of SSRIs, there is a significant gap in understanding the long-term impact of these medications on cognition in healthy individuals. Our presentation will cover three key studies examining chronic escitalopram administration in healthy volunteers. The first is a behavioural study using a number of cognitive tasks, the second a functional magnetic resonance imaging study of reward learning, and the third a PET study utilizing UCBJ to understand the effect of chronic escitalopram on synaptic density. We will discuss how chronic administration of escitalopram influences various cognitive domains, including decision-making, cognitive flexibility, and learning from feedback. Additionally, we will consider important methodological considerations and interpretative challenges when studying serotonergic effects on cognition. Finally, we will outline the broader implications of these findings, particularly for clinical treatments of neuropsychiatric disorders, and propose future directions for research to better understand the long-term effects of serotonin modulation on the brain and behaviour.
