Probing the Pro-Cognitive Potential of Prucalopride: An Eye-Opening Inquiry into Cognitive Enhancement
In an intriguing development in neuropsychiatric research, scientists have examined the neurological impacts of prucalopride, a laxative known to activate serotonin receptors, on cognitive function and mood regulation.
Key Points:
- Serotonin receptors, especially 5-HT4-type receptors, are key targets for antidepressants and influence cognitive function and mood regulation.
- Prucalopride, a selective agonist of the 5-HT4 serotonin receptor, has shown promising results in enhancing cognitive function.
- A study on 50 healthy adults found increased functional connectivity in cognitive networks in the prucalopride group as compared to a placebo group.
Additional Points:
- There was increased functional connectivity between major cognitive networks, specifically the central executive network and regions of the ACC and lateral occipital cortex.
- A decrease in functional connectivity was observed in the default mode network in participants taking prucalopride.
- Participants on prucalopride scored higher in cognitive tests on the day of scanning than those on placebo, suggesting this could be a ‘signature’ of a cognition-improving drug.
Conclusion:
- Prucalopride’s effects on the brain’s cognitive networks could signify its potential as a treatment for depression and cognitive impairment, warranting further research into 5-HT4 serotonin receptor-targeting drugs.

“Our previous studies on prucalopride demonstrated that even at low clinical doses it can improve cognition and memory in healthy volunteers. This latest research provides a neurological mechanism by which this might occur.”
