10 Early Signs of Dementia You Should NEVER Ignore

editor editoron

9. Withdrawal from Work or Social Activities

People may stop pursuing hobbies, attending social events, or engaging in activities they once loved—often because they feel embarrassed or confused.

What it looks like: The avid gardener letting the garden go. The bridge club regular stopping attendance.

10. Changes in Mood or Personality

Anxiety, fear, suspicion, depression, or agitation can appear. People may become easily upset in situations outside their comfort zone.

What it looks like: A usually calm person becoming easily angered. A trusting person becoming suspicious of family members.

What to Do If You Notice These Signs

Step 1: Don’t Panic

Many conditions cause dementia-like symptoms: vitamin deficiencies, thyroid problems, medication side effects, depression, and infections. Some are treatable and reversible.

Step 2: Keep a Log

Write down what you’ve noticed, when it started, and how often it happens. This information is gold for a doctor.

Step 3: See a Doctor

Start with a primary care provider. They can perform a cognitive assessment and order blood work to rule out other causes.

Step 4: Bring Someone with You

A second set of ears (and someone who knows you well) can help remember what the doctor says and add observations.

Step 5: Ask Questions

  • “What could be causing these changes?”

  • “What tests do you recommend?”

  • “If it’s dementia, what are our next steps?”

Risk Factors for Dementia

Uncontrollable Controllable
Age High blood pressure
Genetics Smoking
Family history Diabetes
Obesity
Physical inactivity
Depression
Social isolation

What you can control: Managing blood pressure, not smoking, staying active, eating well, staying socially engaged, and treating depression all reduce risk.

The Bottom Line

Early detection matters. Not because we can cure dementia (we can’t yet), but because:

  • Treatments work better when started early

  • Reversible causes can be identified and treated

  • Planning can happen while the person can participate

  • Quality of life can be maintained longer

If something on this list resonates, please reach out to a healthcare professional. You’re not overreacting. You’re not being dramatic. You’re being an advocate for your health or the health of someone you love.

You deserve answers. You deserve support. And you deserve to move forward with hope.
