MRI and Alzheimer's Diagnosis: Current and Future Uses
Magnetic resonance imaging (MRI) may detect signs of Alzheimer's disease even before mental impairment becomes obvious, though it hasn't yet been confirmed as a foolproof diagnostic tool. Learn about MRI, its current uses and future prospects in the diagnosis of Alzheimer's disease.

The Mini-Mental State Exam and Its Use as an Alzheimer's Scre…
Of the many existing tests that screen for Alzheimer's, the MMSE is widely used and reliable.

Scores may need to be adjusted or interpreted differently to account for a person's age, educational level, an…

Neuropsychological Tests Used In The Evaluation Of Alzheimer's Disease
Neuropsychological testing is sometimes used in the evaluation of Alzheimer's disease to learn more about the nature and level of a person's impairment. Learn about neuropsychological tests commonly used to diagnose Alzheimer's disease, such as the ADAS-Cog, Blessed Test, CANTAB, Clock Drawing Test, Cognistat, and NPI.

Blood Tests Used in the Diagnosis of Alzheimer's Disease
Although science is getting closer, there's still no simple test for Alzheimer's disease. Instead, physicians rule out other causes of symptoms such as memory loss, confusion, and difficulty executing simple tasks. Alzheimer's diagnosis almost always includes blood testing. Learn more about the blood tests involved with Alzheimer's disease diagnosis and what else these tests may discover.

The Montreal Cognitive Assessment and its Use as an Alzheimer…

The Mini-Cog and its Use as an Alzheimer's Screening Test
The Mini-Cog is a rapid Alzheimer's screening test that takes only 3-5 minutes to administer. It combines 3-item recall with the clock-drawing test to determine whether someone does or does not have dementia. It is extremely accurate as an assessment tool, but as with other screening tools does not substitute for a thorough diagnostic work-up.

The AD8 and its Use as an Alzheimer's Screening Test
The AD8 is an 8-item questionnaire that can be administered by a caregiver at home or in the doctor's office. Two or more "yes" answers are highly suggestive of having dementia, and unlike other Alzheimer's tests the AD8 detects changes in function in addition to cognitive symptoms.

Definition of Florbetapir
Florbetapir is a PET scanning radiopharmaceutical compound that was created and tested as a diagnostic tool in Alzheimer's disease. By binding to amyloid-beta that accumulates in the brains of people with Alzheimer's disease, florbetapir was shown to correlate well with actual pathology results found at autopsy.
