Study Links Late-Life Mood Disorders to Dementia Risk

Imagine that feeling sad or being really energetic and happy after you turn 40 could be a sign of a brain problem later on.

Scientists looked at people with these mood changes and found that they sometimes have signs of brain diseases like dementia.

They used special brain scans to see if people with late-life mood problems had a build-up of proteins that are linked to these diseases.

The scientists discovered that people with mood changes were more likely to have these protein build-ups, even before they started having memory issues.

This suggests that taking care of your mental health after 40 is really important for your brain health as you get older.
