A New Type of Memory Loss in Older Adults

This podcast explores Limbic-predominant Amnestic Neurodegenerative Syndrome (LANS), a newly identified condition that primarily affects episodic memory while leaving other cognitive functions relatively intact. LANS is associated with the misfolding of TDP-43, a protein that can accumulate and damage limbic structures. Unlike Alzheimer’s, LANS has a slower onset and lacks definitive diagnostic tests, making research critical for future treatments. With the aging population, understanding and addressing LANS could become as significant as Alzheimer’s research. Share with a friend. Rate, Review, and Subscribe to MedEvidence!
