AI Insight
A small clinical trial found that prucalopride, an existing constipation medication, improved cognitive function in people with a history of depression when taken for approximately one week. Participants who received the drug showed enhanced performance on tests measuring memory, attention, and processing speed compared to those given a placebo. The medication works by targeting serotonin receptors present in both the gut and brain, with no significant side effects observed during the study.
Why it matters
This research suggests a potential new treatment option for cognitive impairment associated with depression, commonly known as "brain fog," which can persist even after other depressive symptoms improve. Repurposing an already-approved drug could accelerate availability of treatment for this debilitating symptom if larger studies confirm these findings.
Understand the Science
An existing constipation drug may have an unexpected new use: helping clear the “brain fog” that often lingers after depression. In a small clinical trial, people with a history of depression who took the medication prucalopride for about a week performed better on tests of memory, attention, and thinking speed than those who received a placebo. The drug targets a serotonin receptor found in both the gut and the brain, and researchers saw no significant side effects.
