RECRUITING

Invasive Decoding and Stimulation of Altered Reward Computations in Depression

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Novel invasive neurostimulation stimulation strategies through neurosurgical interventions are emerging as a promising therapeutical strategy for major depressive disorder. These have been applied mostly to the anterior cingulate cortex, but other limbic brain regions have shown promise as anatomical targets for new neurostimulation strategies. The researchers seek to study neural activity in limbic brain areas implicated in decision behavior and mood regulation to identify novel targets for treatment through electrical stimulation. To do this, the study team will record local field potentials (LFPs) from the orbitofrontal cortex, hippocampus and amygdala of epilepsy participants undergoing invasive monitoring (intracranial encephalography, iEEG) during choice behavior. Leveraging the high co-morbidity of depression and intractable epilepsy (33-50%), neural responses will be compared to reward across depression status to identify abnormal responses in depression. Finally, the researchers will use these as biomarkers to guide development of neurostimulation strategies for the treatment of depression.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years to 80 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. Age 18 years or older
  2. Willing and able to provide informed consent
  3. Able to understand and follow study procedures
  4. Stable medical condition
  1. * Adults over 80 years of age will be excluded as per concerns of cognitive decline.
  2. * Children under 18 will be excluded from the study since the maturation of frontal lobes continues through adolescence and significant differences in frontal lobe functioning between children younger than 18 and adults are often observed.
