"We're trying to show that in old age, memory loss is not unequivocally caused by Alzheimer disease. We can look for other causes."
Previously, the hallmarks of the limbic-predominant amnestic neurodegenerative syndrome (LANS), a memory-loss syndrome in older adults that can often be mistaken for Alzheimer disease (AD), could only be confirmed by examination of brain tissue after a patient's death. Recently, experts at Mayo Clinic have published new criteria of LANS in Brain Communications, providing a framework for clinicians that considers factors such as age, severity of memory impairment, brain scans, and biomarkers that indicate the deposits of specific proteins in the brain.1,2
Researchers used data from more than 200 patients in databases from the Mayo Clinic Alzheimer's Disease Research Center, the Mayo Clinic Study of Aging, and the Alzheimer's Disease Neuroimaging Initiative to develop and validate the criteria. Overall, the established criteria can assist providers to diagnose LANS in a more timely fashion, allowing those living with memory loss opportunities for available treatment, as well as expanding the opportunities for research to further highlight the characteristics of the disease.
Lead author Nick Corriveau-Lecavalier, PhD, a clinical fellow in adult neuropsychology at Mayo Clinic, and senior author David T. Jones, MD, a behavioral neurologist at Mayo Clinic, recently sat down with NeurologyLive® in an interview to discuss the core features required for diagnosing LANS. The duo of experts also talked about how the new criteria differentiate LANS from AD. Furthermore, Jones and Corriveau-Lecavalier spoke about the implications of this new diagnostic framework for treatment approaches in memory-related conditions in older adults.
