Story summary

University of Manchester scientists reported unusually high brain urea in people with frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS).
They measured urea in post-mortem tissue and found the highest concentrations in FTD brains and in ALS motor-control regions.
Lead author Dr. Sasha Philbert said the findings suggest impaired waste clearance may drive neurodegeneration and could become a therapeutic target.
