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.”
Studies of cognitive impairment show salutary effects of acute administration of Ang IV and its analogs, as well as AT4R activation. Brain RAS peptides appear most effective administered intracerebroventricularly, close to the time of learning acquisition or retention testing. Ang-(1-7) shows anti-dementia qualities.
Neurosci Biobehav Rev, 2018 ↗“The effects have been promising, because I found myself not only better in actual routine work, but also studying and learning, which was really hard to me before. It felt like combining mental clarity with neural plasticity.”
