Alzheimer’s disease is the most common cause of dementia. The word dementia describes a set of symptoms that can include memory loss and difficulties with thinking, problem-solving or language. The researchers believe fine-air particles enter people’s brains when they breathe before travelling elsewhere in their bodies via their bloodstreams. Past research suggests such particles, which weigh less than 0.0025mg and are given out in vehicle-exhaust fumes, cause inflammation. The researchers assessed the autopsies’ levels of proteins that are associated with Alzheimer’s.The findings were published in the journal of Environmental Research.
