Amyotrophic Lateral Sclerosis
Amyotrophic lateral sclerosis is a progressive neurodegenerative syndrome characterized by loss of motor neurons. Cognitive impairment occurs in a significant proportion of those affected. Numerous theories of
pathogenesis have been advanced. The most cogent hypothesis is that genetic susceptibilities to neurodegeneration interact with environmental exposures, leading to neuronal injury, glial activation and neuronal death. Modern tools of molecular and cell biology and constructive international collaborations have provided insights into the factors that increase disease susceptibility. The important observation that genes associated with ribonucleic acid (RNA) processing are implicated in disease pathogenesis will undoubtedly influence the direction of research in the coming years. These factors, combined with improvements in clinical trial design, and an improved understanding of the limitations of translating positive findings from animal models to human subjects, are likely to lead to new and successful therapeutic options for patients in the near future.
