A review proposes defining some neurodegenerative diseases by their underlying TDP-43 pathology, rather than by clinical labels alone. The approach includes amyotrophic lateral sclerosis (ALS), frontotemporal dementia, limbic-predominant age-related encephalopathy and other conditions. The authors say this framework could guide development of biomarkers and treatments aimed at fundamental disease mechanisms.
Why this matters
The proposal could help researchers study shared biology across conditions and develop tests that reflect the underlying disease process. It does not change current ALS diagnoses or treatments, and it is not evidence that a new therapy is available.
Limitations and context
This is a review and conceptual framework, not a clinical trial or treatment study. The proposed disease definitions and their usefulness for diagnosis, prognosis, biomarkers and therapy still need to be tested and validated.
