MND is an adult-onset neurodegenerative diseases and one of the commonest neuromuscular disorders.
MND can develop with different clinical elements and
progresses at different rates among individuals. Currently, there are no blood
tests that could help us predict:
- the disease progression rate
- the likely clinical features (e.g. predominant involvement of speech and swallowing or of the limb muscles)
We are testing specific disease biomarkers in the blood. To assess change over time, a blood sample is taken every 3 months. We are studying a range of blood constituents including proteins, DNA and RNA.
From some participants we also collect samples of cerebrospinal fluid. If repeated samples are not possible, a single sample of blood for DNA studies is also helpful.
We also examine control samples from:
- participants without MND
- individuals with similar but unrelated neuromuscular conditions.
Parallel studies of biomarkers in an animal model of MND are informing our choice of biomarkers. The study is in collaboration with Queen Mary University of London, and other participating centres.
