RT Journal Article SR Electronic T1 Therapeutic non-invasive brain stimulation in amyotrophic lateral sclerosis: rationale, methods and experience JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 1131 OP 1138 DO 10.1136/jnnp-2018-320213 VO 90 IS 10 A1 Edmond, Evan C A1 Stagg, Charlotte J A1 Turner, Martin R YR 2019 UL http://jnnp.bmj.com/content/90/10/1131.abstract AB The neurodegenerative syndrome amyotrophic lateral sclerosis (ALS) is characterised by increased cortical excitability, thought to reflect pathological changes in the balance of local excitatory and inhibitory neuronal influences. Non-invasive brain stimulation (NIBS) has been shown to modulate cortical activity, with some protocols showing effects that outlast the stimulation by months. NIBS has been suggested as a potential therapeutic approach for disorders associated with changes in cortical neurophysiology, including ALS. This article reviews NIBS methodology, rationale for its application to ALS and progress to date.
