Memory Problems Linked to Leaded Gas Exposure in Childhood

New studies reveal long-term cognitive risks from 1960s-era atmospheric lead levels

Adults who grew up in U.S. areas with high atmospheric lead concentrations between 1960 and 1974 face a significantly higher risk of memory problems in later life, according to two large-scale studies. Experimental data also show persistent neuronal damage after lead exposure, potentially explaining higher Alzheimer’s vulnerability decades later.
