Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease of motor neurons.
Patients usually live 2-5 years after symptom onset with an unknown cause. In this
research,samples were collected from the cerebral spinal fluid (CSF) of ALS patients
and from subjects that did not have a neurodegenerative disease. Metabolomics
studies were performed on the samples using NMR (Nuclear Magnetic Resonance)
spectroscopy to find biomarkers in the early stages of the disease, and to evaluate
certain biochemical factors that are involved in ALS. The researchers are aware that
this study only focused on nuclear magnetic resonance (NMR), but to achieve a
superior result, the combinations of different approache is better. The results
demonstrated that H NMR spectroscopy combined with other analysis techniques
could detect certain changes in the concentration of some CSF metabolites in ALS.
The mechanisms involved in amyotrophic lateral sclerosis are very complex and none
have been identified as useful biomarkers that can substitutefor the patient’sroutine
check up.
