Is It Alzheimer’s Or Another Dementia? The Right Answer Matters
National Public Radio

In the U.S., older people with dementia are usually told they have Alzheimer’s disease.

But a range of other brain diseases can also impair thinking, and memory and judgment, according to scientists attending a summit on dementias held Thursday and Friday at the National Institutes of Health.

These include strokes, a form of Parkinson’s disease, and a disease that damages brain areas that regulate emotion and behavior.

 ”There’s a host of things that can cause loss of cognitive function,” says Dr. Julie Schneider, a professor at the Rush Alzheimer’s Disease Center in Chicago and scientific chair of the NIH summit. And many patients have more than one disease affecting the brain, she says.
