If you grew up in the U.S. during the 1960s or early 1970s, new research says you may face a higher risk of memory problems today. A study found that people who lived in areas with high lead levels from leaded gasoline were about 20% more likely to report memory issues later in life. That’s because lead, once common in fuel, was released into the air and inhaled for decades before it was banned.
Leaded gas was widely used until the mid-1970s and officially banned in 1996. Experts say nearly half of Americans were exposed to high levels of lead as children. Lead harms brain development, and its effects can last a lifetime. While blood tests only show recent exposure, researchers say the long-term risks are real — even if you don’t feel symptoms now.
Doctors recommend focusing on what you can control. Managing blood pressure, avoiding smoking, staying active, and maintaining social connections can all help protect brain health. And while lead is no longer in gas, it can still be found in older pipes, paint, and even some areas near factories.
