A new study found that repetitive #negative thinking in later life was linked to cognitive decline and greater deposits of two harmful proteins responsible for Alzheimer's disease.
We propose that repetitive negative thinking may be a new risk factor for dementia," said lead author Dr. Natalie Marchant, a psychiatrist and senior research fellow in the department of mental health at University College London, in a statement.
The scans showed that people who spent more time thinking negatively had more tau and beta amyloid buildup, worse memory and greater cognitive decline over a four-year period compared to people who were not pessimists.
The study also tested for levels of anxiety and depression and found greater cognitive decline in depressed and anxious people, which echos prior research.
But deposits of tau and amyloid did not increase in the already depressed and anxious people, leading researchers to suspect repeated negative thinking may be the main reason why depression and anxiety contribute to Alzheimer's disease.
