Oily fish 'hope' for Alzheimer's

Scientists are hoping to discover exactly how oily fish can protect against Alzheimer's disease.

It is known that eating fish such as salmon, sardines and mackerel appears to cut the risk of developing dementia.

But now, Cardiff University researchers funded by £300,000 from the Alzheimer's Research Trust are to investigate how this might help.

In the meantime, the researchers say people should eat oily fish at least twice a week.
