The article “Air pollution, cognitive deficits and brain abnormalities: A pilot study with children and dogs” in the journal Brain and Cognition summarizes the results of the study.
Its authors, from Mexico and the United States, are led by experimental pathologist Lilian CalderÃ³n-GarcidueÃ±as, of the Instituto Nacional de PediatrÃa, Mexico City, Mexico; and the Department of Biomedical and Pharmaceutical Sciences, College of Health Professions and Biomedical Sciences, The University of Montana, Missoula, U.S.A.
They state in the abstract to their paper, “Exposure to air pollution is associated with neuroinflammation in healthy children and dogs in Mexico City."
They studied 55 healthy children (between the ages of seven and 18 years) and seven young (one to two year old) dogs who were regularly exposed to the high air pollution in Mexico City, Mexico.
They also examined 18 healthy children and young dogs in the low air pollution city of PolotitlÃ¡n, Mexico.
The researchers gave all of the children psychometric tests, along with brain magnetic resonance imaging (MRI) scans.
The results of the study are discussed on page two.
