alzheimer's disease
"My mum who has been diagnosed with vascular dementia and was at the stage of being extremely confused about where she was and who close relatives were began taking memantine in January 2015.  In short it has given me my mum back. Mum is now relatively alert, has markedly improved memory and is back in the present.  I had never imagined such an improvement was possible.  It's really strange to be having conversations with mum about what she was like before taking the drug.  Viki"
