Families of New York residents suffering from Alzheimer’s disease or another form of dementia may want to take heed of findings showing the prevalence of doctor misdiagnosis. Treatments are few and many are still experimental, but a study’s authors state that the future treatments will likely be very specific to the type of dementia. Findings show that in the best of situations, nearly a quarter of total Alzheimer’s prevalence was misdiagnosed as either false negative or false positive. The presence of psychosis was a leading factor in a failure to diagnose correctly.
