pyramem is a nootropic. Used to increase blood and oxygen flow to stimulate brain activity. Used for degenerative memory problems and head trauma in eastern europe.

Nootropics are considered "cognitive enhancers" or "smart drugs." They increase brain function by (yes), improving blood circulation in the brain, but they also improve the function of the neurotransmitter acetylcholine via muscarinic cholinergic (ACh) receptors which are implicated in memory processes. Furthermore, they have an effect on NMDA glutamate receptors which are involved with learning and memory processes. Nootropics influence neuronal and vascular functions and increase cognitive function, while at the same time providing a natural source of energy to keep you alert and motivated.
