A study has indicated that stress could cause brain changes which are also seen in Alzheimer's.
Research has shown that people who are stressed could be increasing their chances of developing Alzheimer's disease.
According to a study from the Max Planck Institute of Psychiatry in Munich, stress was seen to promote neuropathological changes which are also present in Alzheimer's disease. The alteration of the tau protein through the addition of phosphate groups causes the protein in the cells to cluster, resulting in nerve cell death in the hippocampus - a brain region which plays a major part in learning and memory.
Osborne Almeida, from the institute, explained: "Our findings show that stress hormones and stress can cause changes in the tau protein like those that arise in Alzheimer's disease."
Dr Simon Ridley, head of research at Alzheimer's Research UK, said that eating healthily could cut the chance of dementia. Ridley explained that although no research has shown one particular food to unquestionably stave off dementia, heightened cardiovascular risk factors are believed to increase the chance of developing the condition.
