The federation, citing the Global Burden of Disease study, a research programme, mentioned, “Based on the investigated data from 1990 to 2013 in 188 countries through the study, it’s demonstrated that air pollution contributes to up to 30% of the burden of stroke.”According to the neurologists in the city, emphasis is laid only predominantly on how lungs are affected due to air pollution while the possible effect of it on brain health is often ignored.Consultant neurologist, M Chandrasekharan, told TOI that the reason behind lesser people talk about adverse effects of air pollution on brain is because it’s an indirect cause.
