environmental toxins may be root of rise in neurological disorders, Doctors warn exposure to omnipresent yet poorly understood chemicals such as microplastics could play a role in dementia, The mystery behind the astronomical rise in neurological disorders like Parkinson’s disease and Alzheimer’s could be caused by exposure to environmental toxins that are omnipresent yet poorly understood, leading doctors warn.

Exposure to environmental toxins may be root of rise in neurological disorders

At a conference on Sunday, the country’s leading neurologists and neuroscientists will highlight recent research efforts to fill the gaping scientific hole in understanding of the role environmental toxins – air pollution, pesticides, microplastics, forever chemicals and more   play in increasingly common diseases like dementias and childhood developmental disorders. Humans may encounter a staggering 80,000 or more toxic chemicals as they work, play, sleep and learn – so many that it is almost impossible to determine their individual effects on a person, let alone how they may interact or the cumulative impacts on the nervous system over a lifespan. Some contact with environmental toxins is inevitable given the proliferation of plastics and chemical pollutants, as well as America’s hands off regulatory approach, but exposure is unequal. In the US, communities of color, environmental toxins , Indigenous people and low income families are far more likely to be exposed to a myriad of pollutants through unsafe housing and water, manufacturing and agricultural jobs, and proximity to roads and polluting industrial plants, among other hazards. It’s likely genetic makeup plays a role in how susceptible people are to the pathological effects of different chemicals, but research has shown higher rates of cancers and respiratory disease in environmentally burdened communities.

Very little is known about impact on brain and nervous system disorder, but there is growing consensus that genetics and ageing do not fully account for the sharp rise in previously rare diseases like Alzheimer’s, Parkinson’s and ALS (amyotrophic lateral sclerosis)  a degenerative disease more likely in army veterans and neighborhoods with heavy industry.Neurology is the branch of medicine focused on disorders of the nervous system – the brain, spinal cord and sensory neural elements like the ears, eyes and skin. Neurologists treat stroke, multiple sclerosis, migraines, Parkinson’s, epilepsy, and Alzheimer’s, as well as children with neurodevelopmental disorders like ADHD, autism and learning disabilities. environmental toxins , The brain is the most complex and important organ in the body – and likely the most sensitive to environmental toxins, but was largely inaccessible to researchers until sophisticated imaging, genetic and molecular techniques were developed in the past 20 years. Going forward, research could help explain why people living in neighborhoods with high levels of air pollution have a higher risk of stroke, as well as examine links between fetal exposure and neurodevelopmental disorders. Rick Woychik, director of the National Institute of Environmental Health Sciences, said: “It’s not just about pesticides. PFAS chemicals are ubiquitous in the environment, as are nanoplastics. And there are trillions of dollars’ worth of demand for nanomaterials, but it’s sobering how little we know about their toxicology.”
