Workshop: Gaps and Opportunities Related to Clinical Detection of Limbic-predominant Age-related TDP-43 Encephalopathy (LATE)


Researchers interested in learning more about clinical detection of Limbic-predominant Age-related TDP-43 Encephalopathy (LATE).


May 25, 2023 | 10 a.m. - 6 p.m. ET

Purpose and background

Limbic-predominant Age-related TDP-43 Encephalopathy (LATE) is a recently described brain disorder that is related to the slow progression of memory loss in aging, thereby mimicking the clinical features of Alzheimer’s disease. It is very common in older adults on its own and even more common in conjunction with Alzheimer’s Disease where it is associated with even faster decline in memory and other aspects of thinking.  There are pathological (autopsy) diagnostic and staging criteria for LATE, but we do not currently have criteria for diagnosis in people during life. This workshop examined the gaps and opportunities related to the clinical detection of LATE both on its own and in conjunction with Alzheimer’s Disease and Related Dementias. Focus included the latest knowledge on the clinical manifestations of LATE and biomarkers for its detection.  In light of emerging therapeutics targeting Alzheimer’s Disease specifically, distinguishing LATE from AD during life is a gap that needs to be filled and will facilitate development of LATE directed therapies. This meeting convened neuropsychologists, neurologists, imagers, pathologists, geneticists, statisticians and NGOs.

Four subcommittees were established to meet in advance of the meeting and discuss appropriate presentations for each section of the agenda. The subcommittee members continued discussion for a second day following the workshop to summarize the workshop and address any remaining questions.
