Dementia is a broad term used to describe a decline in memory and thinking skills that’s severe enough to interfere with a person’s daily life. Among its many forms, the most common is Alzheimer’s disease, which accounts for 60–80% of all dementia cases.
In many instances, dementia is progressive — meaning symptoms gradually worsen over time. Early signs may include forgetfulness, difficulty recalling names or recent events, mood changes, apathy, or even depression.
While some risk factors, like age or genetics, can’t be changed, there are several lifestyle choices that may help lower your risk.
Controllable Risk Factors for Dementia:
- A poor diet lacking key vitamins
- Certain medications that may impair brain function
- Underactive thyroid (hypothyroidism)
- Heart health risks such as high blood pressure, high cholesterol, and diabetes
- Smoking
- Sedentary lifestyle
- Excessive alcohol use
- Repeated head injuries or trauma
9 Ways to Help Protect Your Brain
1. Track Your Health Numbers
Keep an eye on blood pressure, cholesterol, blood sugar, and weight. Managing these early can protect both your brain and heart.
2. Get Enough Vitamin D
Low vitamin D levels are linked to cognitive decline. Regular sun exposure or supplements can help.
3. Challenge Your Brain
Stimulate your mind with puzzles, reading, learning new skills, or playing memory games.
