Amyloid fibrils in those with frontotemporal lobar degeneration (FTLD) contain a little-known protein called TMEM106B. Researchers speculate TMEM106B could be found to be the cause of FTLD.
Researchers identified a group of closely related genes that capture molecular links between Alzheimer's and LATE, a common brain disorder that mimics Alzheimer's symptoms.
LATE, a form of dementia that appears in the oldest-old is often mistaken for Alzheimer's disease, but the brain pathology is very different. The protein TDP-43 appears to play a significant role in the development of LATE. The neurodegenerative disease may progress more gradually than Alzheimer's, but when combined with Alzheimer's disease (a common combination), appears to cause a more rapid decline than either would alone.
