Alzheimer's: How far are we from a cure? Susan Greenfield talks to BBC HARDtalk

How far are we from a cure for Alzheimer’s disease? Professor Susan Greenfield thinks it may not be that far away, but that there needs to be a wholly new approach if one is to be found. But why doesn’t Alzheimer’s get the attention or funding that other diseases attract? Stephen Sackur speaks to the former director of the Royal Institution and leading neuroscientist about her work on dementia and the impact that modern technology could be having on our brains. Professor Greenfield has attracted controversy in the past due to the approach she has taken, and in this Hardtalk she questions the way that the scientific community organises research. So is the current system of peer-review working, and could it actually be holding us back?
