Researchers have identified 15 lifestyle and health factors that contribute to the risk of young-onset dementia (YOD), according to a study published in December 2023. The extensive research analyzed data from over 356,000 people under 65 in the UK.
The findings suggest that low socioeconomic status, social isolation, hearing impairment, stroke, diabetes, heart disease, and depression are linked to an increased risk of YOD. Vitamin D deficiency, high levels of C-reactive protein, and specific genetic variants also play a role.
On the other hand, moderate drinking, higher education levels, and lower physical frailty were associated with a reduced risk of YOD. This suggests that modifiable factors can help prevent or reduce the risk of the condition.
While the study doesn’t prove causation, it provides valuable insights into the causes of YOD and can inform the development of better treatments and preventative measures. The researchers emphasize that living healthier lives may be key to reducing the risk of dementia.
