Can a CT scan of the brain detect dementia?

CT scans create x-ray images of structures within the brain and can show evidence of strokes and ischemia, brain atrophy, changes to the blood vessels and other problems that can bring about dementia. CT scans and MRI scans can show the loss of brain mass associated with Alzheimer’s disease and other types of dementia.

What can be mistaken for dementia?

Can dementia be seen on MRI?

MRI may also assist the differential diagnosis in dementia associated with metabolic or inflammatory diseases. MRI has the potential to detect focal signal abnormalities which may assist the clinical differentiation between Alzheimer’s disease (AD) and vascular dementia (VaD).

How do neurologists test for dementia?
