Long regarded as a multifactorial disorder driven primarily by aging and genetic susceptibility, Alzheimer’s disease is now emerging as an environmental issue. This neurodegenerative condition, the leading cause of dementia worldwide, is characterized by progressive cognitive decline associated with amyloid plaque accumulation and neurofibrillary degeneration. While age remains the main risk factor, hypertension, stroke, and depression are also implicated. A new suspect has now entered the picture: air pollution.
