The rapid rise in chronic and severe diseases worldwide has become a major concern for scientists. Disruptions in daily routines have already increased health risks, and environmental factors are further exacerbating the threat of life-threatening diseases. Recent reports have raised alarms regarding microplastics and their severe health consequences.
Microplastics Detected in the Human Brain
A study led by the University of New Mexico has found that microplastic levels are increasing in the human brain. Experts are worried that the presence of microplastics in the brain may disrupt the blood-brain barrier, potentially leading to serious health risks.
The blood-brain barrier is a membrane-like shield that protects the brain’s blood vessels from harmful substances. Scientists have warned that compared to the liver and kidneys, the brain is accumulating significantly higher amounts of microplastic particles, which could pose serious health risks in the future.
Microplastics Found in the Liver, Kidneys, and Brain
Previously, researchers from the University of New Mexico had discovered microplastics in the liver, kidneys, and brain.
According to a recent study, the concentration of microplastics in the brain is much higher than in the kidneys and liver. Findings show that in 2024, microplastic levels in the brains of deceased individuals were nearly 50% higher compared to those who died in 2016.
Microplastics: A Potential Health Hazard
Microplastics have previously been found in placenta, blood, breast milk, saliva, and arterial plaque. A study published last year indicated that the presence of microplastics in arterial plaque could increase the risk of heart attacks, strokes, and even death.
Professor Matthew Campen from the University of New Mexico College of Pharmacy, who authored the study, expressed his concerns, saying:
"I never imagined that microplastic levels in humans could be so high. I certainly do not feel comfortable knowing that my brain might contain such a large amount of plastic."
Increased Risk of Heart Attacks and Strokes
Another study published in the international journal Nature Medicine suggests that microplastics in the brain are altering its fundamental structure. This may lead to Alzheimer’s, dementia, heart attacks, and strokes, increasing the risk of death by 4.5 times.
From 1997 to 2024, post-mortem studies have shown a significant rise in micro and nano plastic levels in brain tissues. These plastic particles were also found in liver and kidney tissues. Scientists warn that these tiny plastic particles could cause long-term health complications.
Microplastics and the Risk of Dementia
Researchers have previously raised concerns about the connection between microplastic exposure and increased risks of stroke and heart attacks. The latest study now suggests that microplastics in the brain may also elevate the risk of dementia.
Compared to healthy individuals, dementia patients were found to have six times more microplastic accumulation in their brains. The study further suggests that microplastic exposure could be a contributing factor to brain changes that make people more susceptible to dementia and other neurodegenerative diseases.
Microplastics are now a growing global health concern, and further research is crucial to understanding their long-term impact on human health.
