Early Dementia: What You Need to Know
A recent study reveals surprising risk factors for young-onset dementia, affecting those under 65.
- Social isolation and lower education are significant risk factors.
- Lifestyle changes can help manage some risks.
- The APOE gene and certain health conditions play a role.
A new study published in JAMA Neurology has identified 15 factors that can contribute to young-onset dementia, which affects individuals under 65. This comprehensive research, analyzing over 350,000 participants in the United Kingdom, offers crucial insights into this challenging condition. The research identified a range of modifiable and non-modifiable elements.
Dr. Kevin Bickart, an assistant professor in neurology at the University of California Los Angeles Health’s David Geffen School of Medicine, highlights the significance of this study, noting that it examines young-onset dementia risk factors in a way that hasn’t been done before. The study’s large sample size and prospective design, following participants from a healthy baseline to a dementia diagnosis, provide valuable data.
The Biggest Risk Factors Uncovered
The research explored 39 potential risk factors, ultimately pinpointing 15 that significantly impact the development of dementia before age 65. Understanding these factors can empower individuals to take proactive steps toward better brain health. The study’s findings shed light on the complex interplay of factors contributing to this condition.
- Social isolation
- Lower formal education
- Lower socioeconomic status
- Carrying two copies of the APOE gene (a marker that influences Alzheimer’s risk)
- Vitamin D deficiency
- Hearing impairment
- Alcohol use disorder
- No alcohol use (abstinence)
- Depression
- High C-reactive protein levels
- Lower handgrip strength (physical frailty)
- Orthostatic hypotension (a form of low blood pressure)
- Stroke
- Diabetes
- Heart disease
While some risk factors are beyond our control, such as genetics and socioeconomic status, others can be managed through lifestyle adjustments.
Taking Charge: Lowering Your Risk
The study’s findings align with the advice of medical experts, offering actionable steps for reducing the risk of early-onset dementia.
Dr. Arman Fesharaki-Zadeh, an assistant professor of psychiatry and neurology at the Yale School of Medicine, suggests three lifestyle measures that can help lower the risk of young-onset dementia: physical exercise, a nourishing diet, and cognitive, mood, and social stimulation.
“An active daily exercise practice can have far-reaching benefits, which include enhanced neurocognitive function,” Fesharaki-Zadeh said, emphasizing the positive effects of physical activity on neurogenesis and mood.
Next, focus on a nutritious diet. Fesharaki-Zadeh advocates for a Mediterranean-based diet, highlighting its well-documented advantages.
“Such dietary practice, which includes food groups such as green leafy vegetables, olive oil, salmon and blueberries, is rich in vitamins, omega-3 fatty acids, as well as antioxidants ― all neuroprotective factors,” he explained.
To keep your mind sharp, Fesharaki-Zadeh recommends cognitive, mood, and social stimulation.
For cognitive stimulation, this could look like learning a new language or attending a seminar, listening to music or dancing. Basically, anything that engages your mind will help it stay healthy. Mood stimulation, on the other hand, relates to stress reduction practices, “such as mindfulness and yoga,” Fesharaki-Zadeh said.
As for social stimulation, it’s pretty simple: Try to connect with other humans face-to-face and actually talk to them as much as possible. “In the era of pandemic and now post-pandemic, quality social connections should increasingly be encouraged and practiced,” Fesharaki-Zadeh said.
These lifestyle changes offer a proactive approach to brain health, although they don’t eliminate all risks associated with dementia.
More Ways to Protect Your Brain
Beyond these core lifestyle adjustments, several other strategies can contribute to brain health and perhaps reduce the risk of early-onset dementia. While no single method can guarantee complete protection, incorporating these practices into your daily routine can offer additional benefits.
Prioritizing sufficient, quality sleep is essential. Aim for 7-9 hours of sleep each night. Sleep allows the brain to clear out toxins and consolidate memories, playing a vital role in cognitive function.
Managing chronic stress is also critical. Employ techniques like meditation, deep breathing, and spending time in nature to mitigate the negative impacts of stress on the brain. Chronic stress can contribute to cognitive decline.
Regularly participating in brain-training activities and puzzles can help maintain cognitive function. Learning new skills and challenging your mind keeps neural pathways active and strengthens brain health.
Furthermore, it’s crucial to monitor and manage cardiovascular health. High blood pressure, high cholesterol, and diabetes can increase dementia risk. regular check-ups with a doctor are significant.
Lastly, protecting your head is a wise decision. Prevent traumatic brain injuries by wearing a helmet during sports or other activities where there’s a risk of head trauma.
Actionable Tips for Brain Health
- Exercise Regularly: Engage in at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise each week. Include strength training at least two days a week.
- Eat a Brain-Healthy Diet: Focus on a Mediterranean-style diet. Fill up on fruits, vegetables, whole grains, lean proteins, and healthy fats like olive oil.
- Stimulate Your Mind: Learn new skills. Read books. Play games. Engage in activities that challenge your brain and keep it active.
- Prioritize Sleep: Aim for quality sleep, ideally 7-9 hours each night. Establish a consistent sleep schedule and create a relaxing bedtime routine.
- Manage stress: Practise mindfulness, yoga, or other stress-reduction techniques. Engage in hobbies. seek social support.
- Stay Socially Active: Maintain strong social connections. Regularly interact with friends, family, and community members.
- Monitor Your Health: Attend regular check-ups, and keep chronic conditions like high blood pressure, high cholesterol, and diabetes under control through medication and lifestyle modifications.
- Protect your head: Avoid head injuries by wearing helmets during sports and other activities where there is a risk of impact.
Early-onset dementia risk factors include social isolation, lower education, and genetics. Modifying lifestyle and monitoring health can help offset some risks. making informed decisions about your health and lifestyle can offer significant protection.
Adopting a Mediterranean diet, exercising, and stimulating your mind and mood are all brain-healthy practices. These efforts can play a huge role in building brain health.
Myths vs. Facts
| Myth | Fact |
|---|---|
| Dementia is a normal part of aging. | While the risk of dementia increases with age, it is indeed not a normal part of aging. Many older adults never develop dementia. |
| there’s nothing you can do to prevent dementia. | Lifestyle choices such as diet, exercise, and social engagement can definitely help lower the risk of developing dementia, or at least delay its onset. |
| Only older people get dementia. | Young-onset dementia can affect individuals under 65, which is why proactive lifestyle choices are so important. |
| Once you have dementia, there’s no hope. | While there is no cure,early diagnosis and specific treatments and lifestyle changes may help manage symptoms and improve quality of life. |
Frequently Asked Questions
What is young-onset dementia?
Young-onset dementia refers to dementia that develops in individuals under the age of 65.It can be caused by several factors, including genetics, lifestyle, and medical conditions.
What’s the best diet for brain health?
A Mediterranean-style diet that features plentiful fruits, vegetables, whole grains, healthy fats (such as olive oil), and lean protein is a great choice.
Can exercise really help prevent dementia?
