Interesting article in the Guardian recently for anyone who has been impacted by the effects of Alzheimer's disease. Researchers in Toronto have discovered a new drug with the potential to not only stop, but actually improve, memory loss. Clinical trials could start in the next two years on the drug which is derived from benzodiazepine. This is already being considered for application in relation to a number of conditions including Alzheimer's disease and depression. Research and development into drugs like these can give hope to those suffering from these conditions and their families.
