If you’re referring to “10 signs of dementia you should never ignore — and habits you should start today,” there is some good information behind the headline, but it shouldn’t be used as a self-diagnosis. Dementia is not a normal part of aging, and several other conditions—including medication effects, depression, sleep problems, thyroid disorders, and vitamin B12 deficiency—can cause memory or thinking problems.

Occasionally forgetting a name or where you put your keys isn’t necessarily dementia. The bigger concern is persistent or progressively worsening changes that interfere with everyday life.

🧠 Habits worth starting today
There’s no guaranteed way to prevent dementia, but several habits are associated with better brain health and potentially lower risk:
Exercise regularly—include aerobic activity and strength training.
Control blood pressure, cholesterol, and diabetes.
Don’t smoke.
Eat a nutritious, balanced diet, emphasizing vegetables, fruits, whole grains, legumes, and other minimally processed foods.
Maintain a healthy weight.
Get adequate, good-quality sleep.
Stay socially connected.
Keep your brain engaged by learning skills and doing mentally stimulating activities.
Protect your head by using seat belts and appropriate helmets and reducing fall hazards.
Limit alcohol.

These habits reduce risk; they don’t guarantee that someone will never develop dementia. Genetics, age, and other factors also matter.

Most important: if you or a family member has noticeable, progressive changes in memory or thinking, arrange a medical evaluation rather than assuming it’s “just getting older.” Some causes of cognitive problems are treatable.
