摘要

Amyotrophic Lateral Sclerosis (ALS) is a disease that has perplexed investigators and patients since its initial description in the mid nineteenth century. The evidence regarding pathogenesis and progression of ALS does not point to a simple mechanism of disease. It is more than likely that the answer to the mystery of ALS pathogenesis will involve a combination of cellular abnormalities that are triggered by genetic predisposition and/or environmental insults. Ultimately, a balance of injury and the capacity for self-repair is tipped, leading to a physiological and structural disconnection of motor neurons from their targets, and manifesting as clinical weakness or spasticity. A rational approach for drug development for any disease requires some level of understanding of disease mechanisms. For ALS, the lack of a clear cause and the complexity of the experimental data on pathogenesis make this task quite challenging.
