Hidden lead in bones could be sabotaging mental health treatments
NCT ID NCT05887934
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether lead stored in bones is linked to worse mental health or weaker responses to brain stimulation therapies like TMS and tDCS. Researchers will test bone lead levels in 500 psychiatric patients and compare them with cognitive tests and psychiatric symptoms. The goal is to understand if past lead exposure is a hidden risk factor, not to test a new treatment.
