Research Overview
BDNF
BDNF is repeatedly associated with learning, long-term potentiation, and recovery from neurologic injury in preclinical literature. Direct protein delivery is difficult, so most studies focus on pathways that raise endogenous BDNF or on localized experimental administration.
Desmopressin
The literature is mixed, but desmopressin has shown memory-related effects in selected populations and experimental paradigms. Its cognitive effects are usually discussed as a vasopressin-pathway probe rather than a primary nootropic.
