Working with US researchers they developed man-made compounds capable of blocking a nerve cell interaction known to lead to the symptoms of the disease.Working with US researchers they developed man-made compounds capable of blocking a nerve cell interaction known to lead to the symptoms of the disease.
The results of the study - carried out in the laboratory using a model of the disease - have prompted the Alzheimer's Research Trust to help fund a further three years research.The results of the study - carried out in the laboratory using a model of the disease - have prompted the Alzheimer's Research Trust to help fund a further three years research.

"A drug that can stop Alzheimer's disease from killing brain cells is a holy grail for researchers working to overcome the devastating condition which affects more than 500,000 people in the UK," she said."A drug that can stop Alzheimer's disease from killing brain cells is a holy grail for researchers working to overcome the devastating condition which affects more than 500,000 people in the UK," she said.

The number of sufferers is expected to double to more than one million with the general ageing of the population over the next generation.The number of sufferers is expected to double to more than one million with the general ageing of the population over the next generation.
Alzheimer's is linked to the build-up of amyloid protein, which eventually forms "senile plaques".Alzheimer's is linked to the build-up of amyloid protein, which eventually forms "senile plaques".
The amyloid protein inflicts damage by interacting with an enzyme called amyloid beta alcohol dehydrogenase (ABAD) and releasing toxic substances which kill brain cells.The amyloid protein inflicts damage by interacting with an enzyme called amyloid beta alcohol dehydrogenase (ABAD) and releasing toxic substances which kill brain cells.
Researchers at St Andrews University initially focused on developing the three-dimensional shape of ABAD and understanding how amyloid attaches itself to the structure.Researchers at St Andrews University initially focused on developing the three-dimensional shape of ABAD and understanding how amyloid attaches itself to the structure.

Jim Jackson, chief executive of Alzheimer Scotland, also welcomed the results of the study, although he cautioned that more research was required.
