Early-Onset Dementia: More than Genetics at Play!
Researchers have identified over a dozen non-genetic risk factors for dementia in individuals under 65, including alcohol use, social isolation, poor hearing, and heart disease.
Factors in Your Health and Lifestyle that Increase the Risk of Early-Onset Dementia

FRIDAY, Dec. 29, 2023 (HealthDay News) — Did you know that factors such as alcohol use, social isolation, poor hearing, and heart disease can increase the risk of dementia for people under 65? It’s true! Researchers have identified more than a dozen non-genetic factors that play a significant role in the development of early-onset dementia.
While about 370,000 new cases of young-onset dementia are diagnosed worldwide each year, it hasn’t been well-researched—until now. A groundbreaking study conducted by scientists in the U.K. and the Netherlands suggests that targeting health and lifestyle factors may help lower the risk of dementia.
In this study, more than 350,000 people under 65, who were part of the U.K. Biobank study, were followed. The researchers found that individuals with less education, lower economic status, and lifestyle factors such as alcohol use disorder and social isolation, as well as health issues including vitamin D deficiency, depression, stroke, impaired hearing, and heart disease, had significantly higher odds for a dementia diagnosis.
Contrary to popular belief, the study challenges the notion that genetics alone are to blame for early-onset dementia. While specific gene variants did play a role, the findings emphasize the importance of non-genetic risk factors for this condition. Finally, we have evidence that taking action to address a range of different factors might help reduce the risk of this debilitating condition.
🔬 Dive into the Science: This study is the largest and most robust of its kind, revealing the groundbreaking possibility of reducing the risk of early-onset dementia through a combination of targeted interventions. Read more about the study here.

Early-onset dementia can have devastating effects on individuals. As study co-author Stevie Hendriks from Maastricht University in the Netherlands points out, “The people affected usually still have a job, children, and a busy life.” The causes are often assumed to be genetic, but this study sought to explore other risk factors.
Mental health also emerged as an influential factor in young-onset dementia. Chronic stress, loneliness, and depression were found to significantly contribute to the risk of dementia in this group. The fact that mental health plays such a crucial role in young-onset dementia was surprising yet extremely significant, as it opens up avenues to mitigate the risk in this population.
The groundbreaking findings of this study were published in the prestigious Journal of the American Medical Association (JAMA) Neurology on December 26.
Funding for this study was provided in part by Alzheimer’s Research UK, an organization committed to advancing our understanding of dementia and finding ways to prevent and treat this condition. Leah Mursaleen, head of clinical research for the organization, emphasized the importance of these findings in shedding light on the modifiable risk factors for young-onset dementia. It is now widely accepted that up to 4 in 10 dementia cases worldwide are linked to factors such as smoking, high blood pressure, and hearing loss, among others.
While these findings are a breakthrough, further studies are needed to broaden our understanding of this complex topic and develop targeted interventions. The fight against dementia is ongoing and requires a multifaceted approach.

Q&A
Q: What are the non-genetic risk factors identified in this study that contribute to early-onset dementia? A: The study identified several non-genetic risk factors for early-onset dementia, including less education, lower economic status, alcohol use disorder, social isolation, vitamin D deficiency, depression, stroke, impaired hearing, and heart disease. Addressing these factors could potentially reduce the risk of developing dementia.
Q: Is genetics the only factor that determines early-onset dementia? A: No, the study challenges the notion that genetics alone are responsible for early-onset dementia. While specific gene variants do play a role, other non-genetic factors, such as lifestyle and health issues, also contribute significantly to the risk.
Q: How can mental health impact the risk of early-onset dementia? A: Mental health, including chronic stress, loneliness, and depression, has been found to be important factors contributing to the risk of early-onset dementia. This surprising finding suggests that addressing mental health concerns can potentially reduce the risk of dementia in this group.
Q: What does this study mean for the fight against dementia? A: The study provides valuable insights into the modifiable risk factors for early-onset dementia, highlighting the opportunity to take action to reduce the risk of this debilitating condition. By addressing factors such as education, economic status, lifestyle choices, and mental health, we can potentially make a significant impact in preventing dementia.
