Be positive: Negative thoughts affect health

Negative thoughts can increase the risk of diseases such as dementia and Alzheimer's, new research has shown.

Persistent, "obsessive" thinking about negative things also affects the storage of harmful proteins in the brain, which has been linked to Alzheimer's, according to the authors of a study conducted by the University of London.

"Depression and anxiety in middle age are already a well-known factor, but we have now come across a pattern of thinking that may be a hidden reason why people who are depressed or anxious are more likely to develop Alzheimer's or depression," said Dr. Natalie Marchant.

She says chronic patterns of negative thoughts over a long period increase the risk of dementia but emphasizes that shorter periods of negative thoughts have no tacit effect.

"We want to encourage people to reduce patterns of negative thoughts and thus reduce the risk of disease," she said.

The study, which lasted two years, involved more than 350 people over the age of 55 and analyzed their memory, attention span, speech, and ability to navigate space.
