New Drug Rapidly Repairs Age-Related Memory Loss, Improves Mood

A team of Canadian scientists has developed a fascinating new experimental drug that is purported to result in rapid improvements to both mood and memory following extensive animal testing. It's hoped the drug will move to human trials within the next two years. New Atlas reports: Gamma-aminobutyric acid (GABA) is a key neurotransmitter, and when altered it can play a role in the development of everything from psychiatric conditions to cognitive degeneration. Benzodiazepines, such as Xanax or Valium, are a class of drugs well known to function by modulating the brain's GABA systems. This new research describes the development of several new molecules that are structurally based on benzodiazepines, but with small tweaks to enhance their ability to specifically target certain brain areas. The goal was to create a new therapeutic agent that can effectively combat age-related mood and memory alterations caused by disruptions in the GABA systems.

In animal tests the drug has been found to be remarkably effective, with old mice displaying rapid improvements in memory tests within an hour of administration, resulting in performance similar to that of young mice. Daily administration of the drug over two months was also seen to result in an actual structural regrowth of brain cells, returning their brains to a state that resembles a young animal. The new study was published in the journal Molecular Neuropsychiatry.
