Official title
Neural Correlates of Neuropsychiatric Functions
Overview
This ClincialTrials.gov record originally corresponded to the protocol approved under IRB # 202370. The study was expanded to include stimulation and recordings approved under new IRB #211037. The participant data originally acquired from IRB# 202370 will be included in this new record: This study seeks to better understand the neural activity underlying neuro cognitive disorders. Resting state local field potential recordings will be collected from medically refractory epilepsy patients implanted with depth electrodes for seizure localization, and metrics of neural activity will be correlated with psychiatric symptoms as measured from questionnaires. Subjects will also participate in neuro cognitive tasks while neural recordings are performed, and/or receive neural stimulation through implanted depth electrodes. A better understanding of disordered neural activity underlying neuropsychiatric disorders may additionally contribute to novel methods for diagnosing, treating, and preventing these diseases.
Primary outcome measures
- Neural activity correlating with the Center for Epidemiologic Studies Depression Scale - Revised (CESD-R) [Time frame: During patient's epilepsy monitoring stay, approximately 15 minutes]
- Neural activity correlating with the State-Trait Anxiety Inventory (STAI) [Time frame: During patient's epilepsy monitoring stay, approximately 15 minutes]
- Neural activity correlating with the Yale-Brown Obsessive Compulsive Scale (YBOCS) [Time frame: During patient's epilepsy monitoring stay, approximately 15 minutes]
- Neural activity correlating with the Barratt Impulsiveness Scale (BIS11) [Time frame: During patient's epilepsy monitoring stay, approximately 15 minutes]
- Local field potential changes in response to study tasks [Time frame: During patient's epilepsy monitoring stay, approximately 20-30 minutes]
- Behavioral performance changes with stimulation [Time frame: During patient's epilepsy monitoring stay, approximately 20-30 minutes]
- Single unit neuronal spiking changes in response to study tasks [Time frame: During patient's epilepsy monitoring stay, approximately 20-30 minutes]
