Industrial Water Pollution Linked to Increased Risk of Rare Brain Disorder, Major Study Finds

Living near industrial facilities that release pollutants into waterways may increase the risk of developing a rare and serious neurological condition, according to new research published in the medical journal Neurology. Scientists from Harvard Medical School analyzed data from more than 500,000 adults in the United Kingdom over approximately 25 years, identifying 221 people who developed progressive supra nuclear palsy (PSP), a degenerative brain disorder that causes difficulties with balance, walking, eye movements and speech. The findings revealed that people living within approximately five kilometers of facilities releasing pesticides were 66% more likely to develop PSP than those living farther away. Increased risks were also associated with proximity to facilities releasing inorganic pollutants, industrial chemicals and heavy metals such as lead, mercury and cadmium. Researchers found that the association generally weakened as residential distance from these facilities increased, suggesting that environmental exposure could play a role in the disease's development. However, the study did not directly measure individual exposure or prove that polluted water causes PSP, and the condition remained rare regardless of where people lived. Scientists believe the findings highlight the importance of further research into environmental risk factors, improved pollution monitoring and stronger measures to protect public health from potentially harmful industrial emissions.
