Centrophenoxine (meclofenoxate, Lucidril) - Stop your brain from rotting away

• used to improve memory and general cognition in people with dementia (including dementia induced by Alzheimer's disease)
• there is currently no cure for dementia (boo!), but a number of drugs are available to slow its progression (half-hearted yay!)
  
• also has been shown to be useful for treating cerebral atrophy (i.e. your brain rotting away) as well as brain injury due to trauma, chronic alcoholism (e.g. W-K syndrome), and aluminum and barbiturate intoxication (poisoning)
  
• consists of dimethylaminoethanol (DMAE) joined by an ester linkage to parachlorophenoxyacetate (pCPA)
• DMAE is a natural compound found in things including fish and the human brain that is converted by the brain into acetylcholine, a neurotransmitter that is thought to have roles in memory and cognition
• DMAE is also able to scavenge (detoxify) free radicals, which can potentially help to reduce brain damage following injury
• pCPA is a synthetic compound that structurally resembles plant hormones called auxins and, being relatively lipid-lovin', is thought to improve the ability of the drug to cross the blood-brain barrier and get into the brain
  
• has been shown to stimulate brain metabolism, increase the lifespan of lab animals (antiaging effects) and improve learning capacity (nootropic effects)
