Researchers continue studying how lifestyle and environmental factors influence long-term brain health.

How Is Alzheimer's Diagnosed?

There is no single test that can diagnose Alzheimer's disease with complete certainty during life.

Healthcare professionals typically use a combination of:

• Medical history

• Physical examination

• Cognitive assessments

• Neurological examination

• Blood tests

• Brain imaging, such as MRI or CT scans

• Additional tests when appropriate

These evaluations help identify possible causes of cognitive symptoms and rule out other conditions.

Can Lifestyle Support Brain Health?

While there is currently no guaranteed way to prevent Alzheimer's disease, growing evidence suggests that healthy lifestyle habits may help support long-term brain health.

These include:

• Regular physical activity

• A balanced diet rich in fruits, vegetables, whole grains, and healthy fats

• Controlling blood pressure, cholesterol, and blood sugar

• Staying socially engaged

• Challenging the brain through learning and mentally stimulating activities

• Getting adequate sleep

• Avoiding smoking

• Limiting excessive alcohol consumption

These habits also benefit heart health, which is closely connected to brain health.
