Everybody knows that stress isn't healthy but the degree to which it affects the brain could soon be found out. The Alzheimer's Society is about to embark upon a study that questions if stress puts people at risk for developing Alzheimer's disease and other forms of dementia. Professor Clive Holmes from the University of Southampton will be the lead investigator on the project, which has received a £1.5 million package of six grants. "All of us go through stressful events. We are looking to understand how these may become a risk factor for the development of Alzheimer's," Professor Holmes commented. The trial will ask participants to complete a cognitive test, to allow researchers to check their mental health throughout the investigation. This will be repeated every 18 months to track the relationship between stress and cognitive impairment. It is hoped that the study will shed light on new ways to intervene in the development of Alzheimer's through either psychological or drug-based treatments.
