'There are ways to control symptoms of Alzhemier's but nothing that stops it'

Chair of Science at University of Cambridge Chris Smith says there are ways to control the symptoms of Alzheimer's but there is nothing at the moment that can stop it.

He says while scientists are working on bio-markers to predict the disease, it should be prioritised as we have an ageing population with a longer life span.

It is intrinsically linked to age and as we have an ageing population with more people living longer, we are seeing more people manifesting these things because historically not enough people lived to reach the kind of age where this became much of a problem for them.

Chris Smith, Naked Scientist

At the moment where we are is that we can diagnose people who have got the disease... and therefore we can give them symptom control drugs.

Chris Smith, Naked Scientist

We estimate that by the middle of the century it might be as many as one person in five over a certain age to one person in three who is affected, so we are looking at a very big problem which we are sleepwalking into at the moment.
