Midlife Depression Symptoms Linked to Higher Dementia Risk
A big study looked at over 5,800 adults in their 50s and found that people who had many symptoms of depression had a higher chance of getting dementia later in life.
The study followed these people for 25 years.
The symptoms included things like feeling nervous all the time, not being able to concentrate, and not feeling happy or affectionate.
The researchers found that if someone had five or more of these symptoms, they were 27% more likely to develop dementia.
This shows how important it is to take care of our mental health, especially as we get older.
Study analyzed medical data from 5,800 middle-aged adults with an average age of 55.
Depression symptoms assessed from 1997 to 1999, with health followed for 25 years.
Participants with five or more depression symptoms had a 27% higher risk of developing dementia.
Symptoms included difficulty concentrating, loss of confidence, and feeling nervous all the time.
Research highlights the importance of addressing mental health in midlife to potentially reduce dementia risk.
