The Scotsman (September 8, 2009): Infections Can Worsen Alzheimer's
Alzheimer's sufferers who catch a cold or a stomach bug need to be treated as soon as possible to prevent it worsening their dementia, new research has suggested.
A study by scientists at the University of Southampton found a link between the infections and an increase in inflammation-like reactions in the brain, which led to an increased rate of cognitive decline.
The Alzheimer's Society funded research on how inflammatory proteins released during an infection might affect the brain, showed that people who got an infection had twice the rate of cognitive decline as people without infections.
