There's now a way to diagnose Alzheimer's Disease with 80% accuracy.
Because science didn't have an accurate way to diagnose ALZ in 2004 through 2008, my mother's dementia wasn't correctly identified until after her death, when an autopsy was done.
Her physical, behavioral, and mental symptoms were tentatively diagnosed as Lewy Body Dementia, but instead of small hard Lewy bodies, her brain held the protein tangles of ALZ.
Developed by Dr. Frank Rudzicz at the University Health Network's Toronto Rehabilitation Institute, the new method was reported in the December 2015 issue of The Journal of Alzheimer's Disease.
"Linguistic Features Identify Alzheimer's Disease in Narrative Speech" is the title of the research report.
Speech samples were taken from 167 Alzheimer's patients and 97 control persons of similar ages and backgrounds.
The aspects of speech analyzed included
lexical diversity, syntactic complexity, semantic content, and acoustics.
Now a start-up company called WinterLight Labs is working to commercialize the techology and make it available to the public.
