What does air pollution do to your brain in the long term?
The sources we were permitted to use for this answer contain no data on air pollution and brain health. For this topic, please consult a different source specifically focused on this subject, or speak with your doctor.
The available source contains no specific data on air pollution and brain health. The provided study (GBD 2021) maps the global burden of disease for hundreds of conditions, but does not break out the effects of air pollution on the brain. Based on this source, we therefore cannot say anything about what air pollution does to your brain in the long term.
Because the evidence for this specific topic is absent from the provided sources, it would not be responsible to attach a substantive conclusion here. Studies on this subject may exist elsewhere, but those fall outside what we are permitted to use here.
