Motor cortex identified as origin of Lance-Adams syndrome

First described 60 years ago, chronic myoclonus following cerebral anoxia is now known as Lance-Adams syndrome. This is a severe disorder whose mechanisms were, until now, poorly understood. Geoffroy Vellieux, Vincent Navarro, and their colleagues at the Paris Brain Institute now show that this condition originates in the motor cortex. Their findings are published in the journal Neurology.
