Alzheimer’s disease and other dementias that occur late in life are easily misdiagnosed, new research indicates. Researchers autopsied the brains of 426 Japanese-American men who lived in Hawaii and died at an average age of 87. Of those, 211 were diagnosed with dementia when they were alive, and the dementia was most commonly attributed to Alzheimer’s disease.But the autopsies found that only about half of those diagnosed with Alzheimer’s had brain findings consistent with the disease, such as amyloid plaques and neurofibrillary tangles. Rather, most of those diagnosed with Alzheimer’s that was not confirmed had a combination of other brain abnormalities sufficient to explain dementia, including Lewy bodies, hippocampal sclerosis, or generalized brain atrophy.
“Diagnosing specific dementias in people who are very old is complex, but with the large increase in dementia cases expected within the next 10 years in the United Sates, it will be increasingly important to correctly recognize, diagnose, prevent and treat age-related cognitive decline,” study researcher Lon White, MD, MPH, of the Kuakini Medical System in Honolulu, says in a news release. “Larger studies are needed to confirm these findings and provide insight as to how we may more accurately diagnose and prevent Alzheimer’s disease and other principal dementing disease processes in the elderly,” White says.
