Sydney, Apr 22 : Exposure to cigarette smoke induces abnormalities in babies'' brains, thus putting them at increased risk of sudden infant death syndrome, say Australian researchers.
To reach the conclusion, researchers from University of Sydney analysed the brain tissue of babies who had undergone an autopsy at Sydney''s Glebe morgue.
After analysing, they found exposure to any second-hand smoke could precipitate these brain cell changes, and not just exposure in utero by maternal smoking.
