The syndrome is similar to Alzheimer’s illness, however doesn’t progress as rapidly and has a “higher prognosis,” in response to a Mayo Clinic press launch.

The researchers used information from greater than 200 sufferers from the Mayo Clinic Alzheimer’s Illness Analysis Middle, the Mayo Clinic Research of Getting old and the Alzheimer’s Illness Neuroimaging Initiative to create a set of standards that can be utilized to diagnose LANS.
The factors embrace elements like age, mind scans, reminiscence loss signs and sure organic markers, the researchers famous.
The findings had been revealed within the journal Mind Communications on Wednesday.

David T. Jones, M.D., a Mayo Clinic neurologist and senior writer of the research, mentioned his staff sees sufferers with signs of reminiscence loss on daily basis.
Earlier than these standards, analyzing mind tissue after a affected person’s loss of life was the one approach to diagnose the syndrome.
“I’ve been seeing these sufferers for over a decade, the place it’s clear what’s going on is completely different from typical Alzheimer’s illness,” he informed Fox Information Digital through e-mail.
“This paper is placing our medical experience right into a exact framework that others can use to care for his or her sufferers.”
Jones mentioned that in lots of instances, “it’s clear there is a matter with reminiscence, which is then recognized as Alzheimer’s illness — however then a biomarker check or different check would present it was not Alzheimer’s.”
