Are you worried that you might be at risk of Dementia? Read below and thank me later!
Dementia is not diagnosed with one test alone. Doctors combine memory assessments, medical history, physical examinations, laboratory tests, and sometimes brain scans to identify the cause of memory loss.
Here are 6 important tests used in a dementia evaluation.
1. Cognitive screening test
Tests such as the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) assess memory, attention, language, and thinking. These are common initial screening tools, but they do not confirm dementia by themselves.
2. Blood tests
Doctors may check vitamin B12, thyroid function, blood counts, electrolytes, kidney function, and other relevant markers to identify conditions that can cause or worsen memory problems. Specialized Alzheimer’s blood biomarkers may also be appropriate in selected patients. 
3. Brain MRI or CT scan
These scans help identify strokes, tumors, bleeding, fluid buildup, and structural brain changes that may explain symptoms or support a dementia diagnosis.
4. Neurological examination
The clinician checks reflexes, balance, coordination, movement, and other nervous system functions to look for clues about the cause of cognitive changes.
5. Alzheimer’s biomarker testing
Selected blood tests, a spinal fluid test, or an amyloid PET scan can help identify biological evidence of Alzheimer’s disease when clinically appropriate. Results must be interpreted alongside symptoms and other findings. 
6. Neuropsychological assessment
Detailed testing measures memory, reasoning, attention, language, and problem-solving. It can help identify the pattern and severity of cognitive difficulties.
Important message
If you or a loved one is experiencing increasing forgetfulness, confusion, or difficulty managing everyday activities, arrange an assessment with a healthcare professional. Some causes of memory problems are treatable, so early evaluation matters.
Urgent warning: Sudden confusion or sudden difficulty speaking, walking, or moving one side of the body requires emergency medical attention because it may indicate a stroke or another acute illness.
