Bone-Lead Level Associations With Brain and Mental Health

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to assess cumulative lead exposure among treatment-seeking patients in the MUSC hospital system receiving experimental transcranial magnetic stimulation (TMS), transcranial direct-current stimulation (tDCS), an electroencephalogram (EEG), and/or transcutaneous auricular vagus nerve stimulation (taVNS) therapies to determine whether lead exposure represents a risk factor for more severe mental illness or a modifier of treatment response. Information will be obtained from patients with a variety of neuropsychiatric disorders recruited to existing hospital studies. This information will include the results of bone-lead testing, brief cognitive tests, and self-reported psychiatric symptoms and behaviors.

This information will include the results of bone-lead testing, brief cognitive tests, and self-reported psychiatric symptoms and behaviors. It is anticipated that the data will serve as preliminary data for research grant applications to support further data collection among a wider clinical and non-clinical population.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Device: X-Ray Fluorescence Analyzer|The XRF analyzer (the ThermoFisher Niton XL3t GOLDD+) is a portable x-ray fluorescent analyzer specifically configured to measure low levels of metals, lead in particular, in bone. The device is designed to rapidly assess cumulative lead exposure, not to support or sustain human life.|
