Conditions That Can Mimic Alzheimer's Disease
Several medical conditions can cause symptoms similar to Alzheimer's but may be treatable.
Examples include:
-
Vitamin B12 deficiency
-
Thyroid disorders
-
Depression
-
Anxiety
-
Medication side effects
-
Sleep apnea
-
Urinary tract infections (particularly in older adults)
-
Dehydration
-
Other forms of dementia
This is one reason why professional evaluation is so important.
Who Is at Higher Risk?
Although anyone can develop Alzheimer's disease, certain factors increase risk.
These include:
-
Older age
-
Family history
-
Certain genetic factors
-
Cardiovascular disease
-
Diabetes
-
High blood pressure
-
Smoking
-
Physical inactivity
-
Obesity
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.
