Dementia, as a subject, has been researched and explored for many years. Dementia is an umbrella term used to define mental health conditions that cause memory loss, changes in behavior patterns as well as affecting our ability to think. While there is still no cure for dementia, treatment for it involves dealing with the symptoms as well as early intervention. Psychologists and mental health experts have done many studies and found different lifestyle and health factors that can increase or decrease the chances of dementia. Research suggests that many lifestyle choices can increase your chances of developing dementia before age 65, a condition often called young-onset or early-onset dementia. A study published in JAMA Neurology pointed to 15 key risk factors, many of which can be changed or prevented. Others, like having a lower income or inheriting specific genes (APOE4), are much harder or impossible to change. The study looked at health information from over 350,000 people under 65 in the UK Biobank database. By examining everything from genes to environmental influences, researchers were able to identify factors that raise the risk of early dementia. Experts say that these risk factors can harm the brain by causing inflammation and creating harmful chemicals. They also mess with how the brain uses sugar for energy, which is key for brain cells to work right. It's believed that dementia, especially Alzheimer's, happens when the brain can't use energy properly. Key Risk Factors for Early-Onset Dementia Out of many factors studied, researchers found 15 main ones that greatly increase the risk of early-onset dementia: Less schoolingLower income or social standingHaving two copies of a specific gene (called APOE4)Alcohol use disorderFeeling alone (social isolation)Lack of Vitamin DHigh levels of inflammation in the bodyWeaker handgrip strengthNot drinking alcohol (this was also listed, suggesting other health reasons might be at play here)Hearing lossDiabetesHeart diseaseDepressionBlood pressure drops when standing up (orthostatic hypotension)StrokeConnection Between the Risk Factors Researchers note that the same health issues affecting the brains of younger people are also linked to dementia in older people. This might be because we're seeing more young people develop problems like diabetes, which really harm the brain, making early dementia more common. These risk factors are also connected to each other. For example, someone with alcohol use disorder might also have poor eating habits, vitamin shortages, weak muscles, and depression. They could also have other health problems like high blood pressure, diabetes, heart disease, and a higher chance of stroke. These problems can create a cycle: depression might lead to feeling isolated, which could then lead to drinking more as a way to cope, and this can ultimately cause long-term health issues. Steps to Lower Your Risk for Early-Onset Dementia Health organizations suggest that almost 40% of all dementias like Alzheimer's could potentially be prevented or delayed by making healthy lifestyle changes and avoiding chronic diseases like diabetes and high blood pressure. Experts recommend regular physical activity to help prevent dementia. This simply means sitting less and moving your body more. Being active every day offers many benefits for your brain. It helps create new brain cells and connections, grows new blood vessels, and improves your mood. It is also suggested that eating a Mediterranean-style diet and actively doing things that challenge your mind, boost your mood, and connect you with others. Mind challenges can be learning new things (like a language or a musical instrument), going to classes, or simply always being curious and learning throughout your life. Mood boosters include practicing stress-reducing activities like mindfulness or yoga. Social connections are also vital for overall mental and physical health. It's important to spend quality time with others, especially now. Additionally, it's advised to keep your blood sugar well-controlled, even if you don't have diabetes, and get enough good, restful sleep. Our lifestyle choices greatly impact our brain's future. It's important to remember that changes leading to dementia, whether it starts early or later, can begin as much as 30 years before any memory or thinking problems are first noticed.
