Early-onset dementia has been on the rise in recent years — and a major new study has identified the likely reasons.

Researchers from Maastricht University (UM) in the Netherlands and the University of Exeter in the U.K. have identified 15 factors linked to the development of dementia earlier in life.

The study findings were published in JAMA Neurology on Dec. 26, 2023.

“We need more studies investigating risk factors of young-onset dementia to validate our findings,” she said.

“Although this is the largest study on risk factors for young-onset dementia to date, bigger studies are needed to increase the reliability of the results,” Henriks added.
