Lead Exposure Intervention Program

The goal of this clinical trial is to learn if BLL (blood lead level) screening and "healthy home" lead prevention program created in the US is adaptable to a Sub-Saharan African context. It will also work to address child lead exposure in Nairobi, Kenya. The main questions it aims to answer is: * Can materials and protocols developed for a US audience be effective in a Sub-Saharan African one? * Is there a difference in learning and action between groups that receive different degrees of intervention? Researchers will compare the outcomes of a group that received lead risk reduction information only in the clinical setting to a group that also received a home visit and tailored risk reduction messages. Participants will: * Have their child's blood lead levels measured at several timepoints * Take part in a questionnaire about lead risk * Receive lead risk reduction messaging either only in the clinic setting or also in their homes * Have their knowledge and risk reduction behaviors measured

Bone-Lead Level Associations With Brain and Mental Health

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.
