Most neuropsychological tests don't tell Alzheimer's disease from vascular dementia
Date:7/8/2009

WASHINGTON Most of the cognitive tests that have been used to decide whether someone has Alzheimer's disease or vascular dementia have not been very helpful when used alone. A new report published by the American Psychological Association concluded that when older people are confused and forgetful, doctors should base their diagnoses on many different types of information, including medical history and brain imaging.

Both Alzheimer's disease and vascular dementia affect learning and memory, behavior and day-to-day function. Even so, they're caused by different problems in the brain and require different medical approaches. It's important to tell them apart accurately, stresses the study in July's Neuropsychology. Valid diagnoses can help doctors treat patients more effectively, and help patients and families better understand their situations.

Jane Mathias, PhD, and Jennifer Burke, M.Psych.(Clinical), both from the University of Adelaide, analyzed 81 previously published studies that compared the cognitive testing of people diagnosed with dementia of the Alzheimer's (4,867) and vascular type (2,263). The average age across participants was 75.

Of the 118 different tests that were used in more than one study, Mathias and Burke found that only two were able to adequately differentiate between Alzheimer's and vascular dementia.

The Emotional Recognition Task (the ability to identify facial expressions in photographs and match emotional expressions to situations, at which people with Alzheimer's were better) and Delayed Story Recall (at which people with vascular dementia were better), were the only tests that appeared to reliably tell the two groups apart.

Even so, whether due to individual variability (people start at different baselines) or possible undiagnosed mixtures of Alzheimer's and vascular disease, there was enough overlap between the two groups to signal the need for more information. Because of th
