Diagnosis of Vascular dementia

There's no specific test that confirms you have vascular dementia. Diagnosis of vascular dementia is done by medical history for stroke or disorders of the heart and blood vessels, and results of tests that may help clarify your diagnosis.

•Lab tests

Lab diagnosis of vascular dementia is done by testing blood pressure, cholesterol, blood sugar or by testing thyroid disorders and vitamin deficiencies

•Brain imaging

Images of your brain can pinpoint visible abnormalities caused by strokes, blood vessel diseases, tumors or trauma that may cause changes in thinking and reasoning.

•Computerized tomography (CT) scan

A CT scan can provide information about your brain's structure; tell whether any regions show shrinkage; and detect evidence of strokes, ministrokes (transient ischemic attacks), blood vessel changes or tumors.

•Magnetic resonance imaging (MRI).

An MRI uses radio waves and a strong magnetic field to produce detailed images of your brain. MRIs are generally the preferred imaging test because MRI can provide even more detail than CT scans about strokes, ministrokes and blood vessel abnormalities.

•Carotid ultrasound

This procedure uses high-frequency sound waves to determine whether your carotid arteries which run up through either side of your neck to supply blood to the brain which shows signs of narrowing as a result of plaque deposits or structural problems. This test may include a Doppler ultrasound, which shows the movement of blood through arteries in addition to structural features.

•Amyloid Imaging in Dementia

Amyloid imaging is a technique performed in nuclear medicine. It uses PET ligands that allow in vivo detection of amyloid plaques, a core pathologic feature of Alzheimer disease and dementia.
