There's still no known cure for Alzheimer's disease but a study published this week claims that they are closing in on a treatment that will reverse memory loss with the help of mental simulation and drug treatment.

The said study was conducted by Howard Hughes Medical Institute and the Massachusetts Institute of Technology neuroscientist Li-Huei Tsai. Accordingly, the treatment was conducted to mice with a condition like Alzheimer's.

To make things a little easier, the process included placing the mice inside some sort of a miniature Disneyland and using a kind of drug that promotes brain nerve cell development (histone deacetylase or HDAC). According to Tsai, this suggests that lost memories are not actually erased. She explained,

We show, I believe, the first evidence that even if the brain suffered some very severe neurodegeneration and the individual exhibits very severe learning impairment and memory loss, there is still the possibility to improve learning ability and recover to a certain extent lost long-term memories.
