Scientists at Mayo Clinic say they have identified a new type of memory loss that is very similar to Alzheimer’s disease, but doesn’t progress as quickly and has a “better prognosis.'
Scientists at Mayo Clinic in Minnesota say they have identified a new type of memory loss. Limbic-predominant amnestic neurodegenerative syndrome, or LANS, affects the brain's limbic system, which helps to regulate emotions and behavior. The syndrome is very similar to Alzheimer’s disease, but doesn’t progress as quickly and has a 'better prognosis,' according to a Mayo Clinic press release.
The researchers used data from more than 200 patients from the Mayo Clinic Alzheimer's Disease Research Center, the Mayo Clinic Study of Aging and the Alzheimer's Disease Neuroimaging Initiative to create a set of criteria that can be used to diagnose LANS. The criteria include factors like age, brain scans, memory loss symptoms and certain biological markers, the researchers noted. The findings were published in the journal Brain Communications on Wednesday.
David T. Jones, M.D., a Mayo Clinic neurologist and senior author of the study, said his team sees patients with symptoms of memory loss every day. Before these criteria, analyzing brain tissue after a patient’s death was the only way to diagnose the syndrome. 'I’ve been seeing these patients for over a decade, where it’s clear what is going on is different from typical Alzheimer’s disease,' he told Fox News Digital via email.
