Prucalopride Boosts Memory in 50 Post-Depression Patients After 7 to 10 Days

Summary
Fifty adults recovered from depression showed better word recall, faster working-memory performance and more accurate face recognition after taking 2 mg of prucalopride daily for 7 to 10 days in a randomized placebo-controlled trial.
Composite cognitive scores favored the constipation drug, with accuracy at z = +0.59 and speed at z = -0.69 on non-emotional tasks, while emotional processing changed little compared with typical antidepressant effects.
Researchers linked the gains to prucalopride's action on 5-HT4 serotonin receptors found in memory-related brain regions; animal studies suggest that pathway can quickly raise BDNF, a protein tied to neural connections.
The findings target a common unmet need: about 80% of people in a depressive episode report memory or concentration problems, and more than 40% still have them after mood symptoms lift.
The team said the results are early-stage because the study was small, short and skewed toward younger, white, highly educated women, though side effects were mild and the drug is already licensed for constipation.

Prucalopride Significantly Improves Cognition in Adults After Depression: New Clinical Evidence and Future Directions
Overview
A major new study published in June 2026 found that prucalopride, a drug usually used for constipation, can improve cognitive function in adults who have recovered from depression. The research involved 50 participants aged 18 to 40, all with a history of at least two depressive episodes but not currently depressed or on psychiatric medication. Using a rigorous randomized, placebo-controlled, double-blind design, the study ensured that any cognitive improvements could be directly linked to prucalopride. This breakthrough suggests prucalopride may help people struggling with memory or attention problems even after their mood has stabilized.
