There is an unmet need to improve therapy for neuropsychiatric comorbidities that are highly prevalent in persons with epilepsy (PWE). However, diagnosing and monitoring the neurobehavioral symptoms is challenging as their presentation can overlap with seizures. In this retrospective study, we report the advantage of chronic ambulatory electrocorticography (ECoG) from implanted Responsive Neurostimulator System (RNS®) in characterizing these psychosomatic paroxysms as a possible ictal, postictal, or interictal phenomenon and how the diagnosis guided the therapy choices. Five out of 21 patients with RNS had neuropsychiatric symptoms (panic attack, psychosis, conversion, and somatization disorders) that overlapped with their seizure semiology and were found to benefit from the use of RNS ECoG data by timely diagnosing and titrating targeted therapies. The cases illustrate the use of RNS ECoG data in diagnosing and improving the management of comorbidities in PWE. The ability to access RNS ECoG data and correlate it with patient symptoms is unique among available therapeutic options for PWE.
