Ginkgo biloba extracts have shown the greatest cognitive and functional benefits, though their clinical significance remains uncertain, and certainty of evidence is overall low. Future trials should focus on a single VCI subtype, prioritize interventions with a strong mechanistic rationale, standardize diagnostic criteria, ensure adequate power for chosen outcomes, test against placebo, and implement FAIR data sharing to accelerate therapeutic discovery.

“The effects have been incredible. It feels like my background distractibility has just vanished. I can lock in and focus even when my phone and other distractions are right next to me.”
