The development of hyperexcitability involving the central and peripheral nervous system has emerged as a pathophysiological process linked to the development of amyotrophic lateral sclerosis (ALS).1 In terms of causation, from a cortical perspective, hyperexcitability may evolve due to a range of factors, including dysfunction of glutamate transport mechanisms, defective RNA editing resulting in abnormal activation of specific glutamate receptors, and alteration of inhibitory signalling through pathological changes involving interneurons. Evidence supporting the role of cortical hyperexcitability has accumulated predominantly through neurophysiological …
