Can you imagine a drug that would make it easier to learn a language, sharpen your memory and help those with dementia and Alzheimer’s disease by rewiring the brain and keeping neurons alive?People with a dementia such as Alzheimer's disease lose their memory when brain cells shrink and die because connections can no longer transfer information.New Rutgers research published in the Journal Neuroscience found that a drug – RGFP966 – administered to rats made them more attuned to what they were hearing, able to retain and remember more information, and develop new connections that allowed these memories to be transmitted between brain cells.
