(Phoenix, AZ) – A groundbreaking new study has revealed a disturbing link between exposure to the widely used herbicide glyphosate and lasting brain damage in mice. the research, conducted by arizona State University’s Ramon Velazquez and colleagues at the Translational Genomics Research Institute (TGen), suggests that even brief contact with glyphosate can trigger meaningful inflammation in the brain, a hallmark of neurodegenerative diseases like Alzheimer’s.
The study, published in the Journal of Neuroinflammation, tracked the presence and impact of glyphosate byproducts in the brains of mice long after exposure. The findings revealed a persistent and concerning array of damaging effects on brain health.
“The human brain is incredibly resilient, but this research shows that even a short exposure to glyphosate can have long-lasting consequences,” said velazquez. “This raises serious concerns about the potential impact of glyphosate on human health, especially given it’s widespread use in agriculture.”
Glyphosate is one of the most commonly used herbicides in the United States and globally. It is indeed frequently enough sprayed on crops to kill weeds, and residues can remain on food products. The study’s findings add to a growing body of research suggesting that glyphosate may pose a risk to human health.The research team observed significant brain inflammation in mice exposed to glyphosate, a condition associated with neurodegenerative diseases. They also found evidence of accelerated Alzheimer’s disease-like pathology in the exposed mice.
While further research is needed to determine the direct implications for humans,the study’s findings raise urgent questions about the safety of glyphosate and its potential impact on brain health.

Common Herbicide Linked to Brain Damage in Mice, Raising Concerns About Human Health
New research from Arizona State University suggests that glyphosate, the world’s most widely used herbicide, may pose a serious threat to brain health.
The study, conducted by researchers at ASU’s Biodesign Institute and the Translational Genomics Research Institute (TGen), found that mice exposed to glyphosate exhibited premature death, anxiety-like behaviors, and a buildup of a harmful byproduct in their brain tissue.
“Our work contributes to the growing literature highlighting the brain’s vulnerability to glyphosate,” says lead researcher Dr. Jose Velazquez,an assistant professor with ASU’s School of Life Sciences. “Given the increasing incidence of cognitive decline in the aging population, particularly in rural communities where exposure to glyphosate is more common due to large-scale farming, there is an urgent need for more basic research on the effects of this herbicide.”
Glyphosate’s Persistence Raises Red Flags
The study, published in [Journal Name], revealed that a byproduct of glyphosate, aminomethylphosphonic acid, accumulated in the brain tissue of exposed mice. This finding is particularly concerning because it suggests that glyphosate, and its metabolites, may persist in the body and accumulate over time, potentially leading to long-term health consequences.
“My hope is that our work drives further investigation into the effects of glyphosate exposure,which may lead to a reexamination of its long-term safety and perhaps spark discussion about other prevalent toxins in our environment that may affect the brain,” says Samantha K. Bartholomew, a PhD candidate in the Velazquez Lab and first author of the study.
Widespread Exposure and Lingering Questions
Glyphosate is used extensively on crops like corn, soybeans, and wheat, making exposure to the herbicide widespread. The U.S. Geological Survey estimates that approximately 300 million pounds of glyphosate are used annually in the United States alone.
While the Environmental protection Agency (EPA) considers certain levels of glyphosate safe for human exposure, recent studies, including this one, challenge that assertion. The EPA maintains that glyphosate is minimally absorbed into the body and excreted unchanged. However, the new research suggests that glyphosate and its metabolites can persist in the body and accumulate in brain tissue, raising questions about existing safety thresholds.
A Call for Further Research
The ASU study builds on previous research that demonstrated glyphosate’s ability to cross the blood-brain barrier, a protective layer that typically shields the brain from harmful substances. This finding, coupled with the new evidence of brain damage and metabolite accumulation, underscores the need for further investigation into the long-term health effects of glyphosate exposure.
As Dr.Velazquez emphasizes, “There is an urgent need for more basic research on the effects of this herbicide, particularly considering the increasing incidence of cognitive decline in our aging population.”
Common Herbicide Linked to Brain Inflammation, Raising Concerns About Long-Term Health Risks
Study Finds glyphosate Persists in Brain Tissue, Potentially Contributing to Neurodegenerative Diseases
(Phoenix, AZ) – A groundbreaking study published in the journal of Neuroinflammation has raised serious concerns about the potential long-term health risks associated with glyphosate, the active ingredient in the widely used herbicide Roundup. Researchers at the Translational Genomics Research Institute (TGen) found that even short-term exposure to glyphosate can lead to persistent brain inflammation in mice, a key factor in the growth of neurodegenerative diseases like Alzheimer’s.
“Herbicides are used heavily and ubiquitously around the world,” says Dr. Pierre Pirrotte, associate professor in TGen’s Early Detection and Prevention Division and senior author of the paper. “These findings highlight that many chemicals we regularly encounter, previously considered safe, may pose potential health risks. Though, further research is needed to fully assess the public health impact and identify safer alternatives.”
The study, conducted on both normal mice and those genetically modified to develop Alzheimer’s-like symptoms, revealed that glyphosate exposure induced neuroinflammation in all subjects.Even at low doses, similar to the current acceptable limit for human exposure, the herbicide caused a persistent increase in inflammatory markers in the brain and blood, even after a six-month recovery period.
glyphosate’s impact on the Brain
Glyphosate works by inhibiting a specific enzyme pathway in plants, crucial for producing essential amino acids. However, this mechanism also affects biological systems in mammals. The study found that the main metabolite of glyphosate, aminomethylphosphonic acid, accumulated in the brains of both normal and Alzheimer’s model mice.”Our goal is to identify environmental factors that contribute to the rising prevalence of cognitive decline and neurodegenerative diseases in our society,” says Dr. Rosa Velazquez, lead author of the study. “By unveiling such factors, we can develop strategies to minimize exposures, ultimately improving the quality of life for the growing aging population.”
The researchers hypothesize that this prolonged inflammation could drive the progression of neurodegenerative diseases, including Alzheimer’s. Amyloid-β and Tau,key proteins that form plaques and tangles in the brains of Alzheimer’s patients,were found to be elevated in the mice exposed to glyphosate.
Call for Further Research and Safer Alternatives
While the study provides compelling evidence of glyphosate’s potential neurotoxic effects, further research is needed to fully understand the long-term health implications for humans.The researchers stress the need for continued vigilance and intensified surveillance of glyphosate’s neurological and other negative health effects.
This study adds to a growing body of research raising concerns about the safety of glyphosate. As the debate over its use continues, the findings underscore the importance of exploring safer alternatives to protect human health and the environment.
