In recent years, numerous studies have found that the brain’s ability to detoxify is impaired in people with dementia, leading to the buildup of harmful substances like microplastics, heavy metals, and “forever chemicals.” These toxic buildups are believed to accelerate cognitive decline by damaging brain tissue and disrupting neural function.
Supporting the body’s detoxification processes is therefore essential for maintaining brain health.
Toxin Accumulation in the Brains of Dementia Patients
A study published in Nature Medicine in February analyzed brain tissue samples from dementia patients in New Mexico who died between 2019 and 2024. Researchers found a median concentration of 26,076 micrograms of microplastics per gram of brain tissue—more than 20 times higher than levels measured in samples collected from the eastern United States between 1997 and 2013.
