About this trial
The CADET Trial will investigate the effectiveness of deep brain stimulation (DBS) to reduce the frequency of seizures in children with Lennox-Gastaut syndrome (LGS). The CADET Trial will use a non-CE/UKCA marked device - the Picostim DBS system.
The SMART-DBS study is a sub-study of the CADET Trial. SMART-DBS will investigate the application of adaptive DBS for the treatment of children with LGS. Children will be recruited after they exit from either the prior 'CADET Pilot Study' or 'CADET Trial' - meaning that these children will already be receiving therapy with an already implanted Picostim device.
