Scientists Reveal Six Middle Age Early Warning Signs of Dementia
Summary
Researchers from University College London found that certain signs of depression in middle age may increase the risk of developing dementia later in life. They identified six specific symptoms linked to this increased risk through a long-term study of over 5,000 adults in the UK. The study suggests that recognizing these symptoms early could help in preventing dementia.Key Facts
- Over 55 million people around the world have dementia, a number expected to increase to 153 million in 25 years.
- The study examined 5,811 adults aged between 35 and 55, beginning in 1985 to identify risk factors for dementia.
- Six depression symptoms in midlife were found to increase dementia risk: losing confidence, fear of facing problems, lack of affection, constant nervousness, dissatisfaction with task performance, and concentration issues.
- Participants showing five or more of these symptoms were classified as depressed.
- 10.1% of the participants developed dementia during the study's 20-year follow-up.
- People with these symptoms in midlife had a 27% higher risk of developing dementia, especially those under 60.
