Younger people can also develop dementia. Some risk factors can be avoided, as a large-scale study now shows.
When many people think of dementia, they think of memory problems in old age. Younger people can also be affected. If the first symptoms appear before the age of 65, it is referred to as “young onset dementia”. Researchers from the University of Exeter (UK) and Maastricht University (Netherlands) have now identified 15 factors that increase the risk of early dementia in a large-scale study.
Early dementia – not just genetic causes
According to the assessment of the German Alzheimer Society In Germany, around 100 out of 100,000 people between the ages of 45 and 65 are affected by the early form of dementia. From the age of 65, the number increases to around 5,000 per 100,000 people. The symptoms of dementia are varied: initially, short-term memory declines and those affected have difficulty remembering things. As the disease progresses, they also lose their long-term memory, become disoriented, inattentive and can no longer articulate themselves properly. Ultimately, sufferers lose their ability to think and with it their perception, experience and behavior.
It is known that genetics plays an important role in dementia in younger ages. Scientists from Exeter and Maastricht have now been able to prove in a large study that lifestyle and environmental influences are also crucial. For those in the trade magazine JAMA Neurology In a published study, they analyzed data from 350,000 people under the age of 65. The results show that risks can actually be reduced.

15 factors increase the risk of early dementia
The data comes from the UK Biobank, a large database from Great Britain. The research team considered a wide range of risk factors and found that the following increase the likelihood of early dementia:
- a low level of education
- a low socioeconomic status (low education, income, property)
- genetic predisposition
- Alcohol abuse
- social isolation
- chronic stress
- Vitamin D deficiency
- depressions
- stroke
- diabetes
- high blood pressure
- physical frailty
- sitting for long periods of time (lack of exercise)
- hearing impairment
- Heart disease in childhood
Professor David Llewellyn from the University of Exeter in a statement from the university: “This is the largest and most meaningful study of its kind ever conducted. “Excitingly, for the first time, it appears that we may be able to take action to reduce the risk of this debilitating disease.”
Early dementia is particularly stressful
Dementia is particularly stressful for younger people. It often takes some time before diagnosis; those affected usually still have a job, children and a busy life. The range of support offers is also loud German Alzheimer Society small amount. Those affected and their relatives are dependent on support because dementia changes relationships and partnerships, early retirement may reduce the family income and support or even care must be guaranteed over a long period of time.
Study results could help with prevention
Sebastian Köhler, Professor of Neuroepidemiology at Maastricht University: “We already knew from research on people who develop dementia in old age that there are a number of modifiable risk factors.” The current study shows that in addition to physical health, mental health is also important Health plays a role. For example, stress and loneliness increase the risk of developing dementia. “I was surprised that this is also visible in young people with dementia and could also offer opportunities for risk reduction in this group.”
And also Dr. Janice Ranson, scientist at the University of Exeter, is optimistic: “Our research is breaking new ground […] We believe this could usher in a new era of interventions to reduce new cases of this disease.”
Tips for a good memory
If you are worried about developing dementia in your life, you can at least reduce your risk of developing the disease with a few tips: It is important to regularly check your blood sugar, blood pressure and cholesterol levels and to eat a healthy diet with plenty of vegetables and valuable vegetable oils. Regular relaxation helps to reduce stress and reduce the risk of dementia-promoting depression and sleep disorders. Owning a dog can also have a positive effect on memory performance as it prevents a lack of exercise and also reduces the risk of depression.
