Antiepileptic drug reduces motor neuron excitability in ALS

The antiepileptic drug ezogabine reduced pathologic excitability of cortical and spinal motor neuron cells that are early signs of clinical dysfunction in people with amyotrophic lateral sclerosis (ALS), according to a study conducted by the Neurological Clinical Research Institute of Massachusetts General Hospital (MGH). In addition to providing a clearer understanding of motor neuron excitability as an important disease pathway for ALS, the multi-site study, published in JAMA Neurology, involves the first clinical investigation of ALS (also known as Lou Gehrig's disease) using a drug identified through an induced pluripotent stem cell (iPSC) model.
