This study aims to understand how environmental pollutants — including heavy metals, microplastics, and other contaminants — may contribute to serious brain diseases like tumors, stroke, and dementia. Researchers will collect blood, urine, hair, and tissue samples from patients with these conditions to measure pollutant exposure and explore how these toxins might trigger disease. The goal is to identify new warning signs and prevention strategies based on pollutant exposure.
Scientists have growing evidence that we are all exposed to pollutants that can reach and damage the brain, but we don't yet understand exactly how these exposures lead to brain tumors and strokes in real patients. This large study will gather the clinical data needed to understand this connection and help doctors identify people at highest risk.

If you enroll, you will donate samples (blood, urine, hair, and possibly tissue) that researchers will analyze for pollutant exposure. The study involves 500 participants total and is being conducted at Beijing Tiantan Hospital. Your samples and health information will help researchers understand whether and how environmental pollutants contribute to your condition.
