The Washington Post (3/28, Dennis) reports that research (3/28) published in the Journal of the American Medical Association indicated kids “with elevated blood-lead levels at age 11 ended up as adults with lower cognitive function and lower-status occupations than their parents.”

TIME (3/28, Sifferlin) reports that for the study, investigators “followed 565 people in New Zealand who were part of a study of people born between 1972 and 1973.” Study participants “had their blood lead levels measured when they were 11 years old, and the researchers followed up with blood tests about decades later, when they were 38.”

Reuters (3/28, Rapaport) reports that study “participants with childhood blood lead levels above 10 micrograms/dl had average adult IQ test scores 4.25 points lower than their peers with lower blood lead levels.” The investigators, “after accounting for factors that can influence adult IQ and earnings such as childhood IQ and socioeconomic status as well as mothers’ IQ…still found that higher lead levels in childhood were” linked to “downward social mobility.”

In “Science Now,” the Los Angeles Times (3/27, Kaplan) reports, “The longer a mother nurses – and the longer she does so exclusively – the bigger the benefits,” research indicates. One “perceived benefit of breastfeeding is the possibility that it boosts a baby’s brain.”

CNN (3/27, Kounang) reports a study published in Pediatrics, however, indicates “breastfeeding has little impact on long-term cognitive development and behavior.” Researchers arrived at this conclusion after following “7,478 Irish children born full term, from the time they were nine months old,” then evaluating them “at three years and again at five years of age.”

Medscape (3/27, Melville) reports that even though “guidelines for initiating treatment of symptoms of Alzheimer’s disease (AD) with cholinesterase inhibitors are well established, guidance and consensus as to when, how, and even whether to discontinue the treatment are lacking,” researchers concluded in a presentation given at the American Association for Geriatric Psychiatry’s annual meeting.
