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.
Alzheimers Dement, 2025 ↗“Cerebrolysin is by far the best nootropic I have ever used...my memory, recall ability, sensitivity to music, observance over my emotions, thinking faculties have all improved to a noticeable amount.”
Moderate-certainty evidence indicates that Cerebrolysin or Cerebrolysin-like peptide mixtures derived from cattle brain probably have no beneficial effect on preventing all-cause death in acute ischaemic stroke. Moderate-certainty evidence suggests that Cerebrolysin probably has no beneficial effect on the total number of people with serious adverse events. Moderate-certainty evidence also indicates a potential increase in non-fatal serious adverse events with Cerebrolysin use.
