UK trial tests diabetes and ADHD drugs as Alzheimer's treatments

A new UK clinical trial called AD-SMART will test several drugs at once for Alzheimer's disease, beginning with two repurposed medicines used for type 2 diabetes and ADHD. Scientists hope the approach could cut years from the search for treatments. It will check whether the drugs ease memory and thinking problems. Alzheimer's affects about 600,000 people in the UK.
