Research Overview
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.
NPY
NPY has been shown in animal studies to protect neurons from excitotoxic injury and to dampen stress-linked cognitive impairment. It is often discussed as a counterbalance to overactive glutamatergic and stress pathways in the brain.
