Prucalopride Improves Brain Fog in 50 Depression-Recovered Adults as 2mg Trial Boosts Memory

Summary
A 50-person randomized trial found prucalopride improved memory, attention and executive function in adults who had recovered from depression but still faced cognitive problems.
The 2mg constipation drug was given for seven to 10 days against placebo, and users became faster and more accurate on "cold" cognitive tests, with accuracy up z=+0.59 and response times improving to z=-0.69.
Researchers said the effect may stem from activating the serotonin 5-HT4 receptor, which is present in both the gut and the brain, making the drug a candidate for repurposing.
No significant side effects were reported in the 18-to-40-year-old participants, all of whom had at least two prior depressive episodes and were off current medication.
The findings, published in Psychological Medicine, offer early evidence for a treatment area with no approved drugs specifically targeting depression-related brain fog.

Prucalopride Shows Promise for Post-Depression Brain Fog: New 2026 Trial Highlights Cognitive Gains and Next Steps
Overview
A recent randomized controlled trial has revealed that prucalopride, a 5-HT4 receptor agonist, may significantly improve cognitive function in people recovering from depression who still struggle with brain fog and mental difficulties. These persistent cognitive problems, such as trouble with memory and concentration, often remain even after mood symptoms have lifted, deeply affecting daily life and quality of life. The study marks an important step forward by showing that prucalopride can target these non-emotional cognitive deficits, opening a promising new direction for treatment and offering hope for more complete recovery after depression.
