Study Finds Smoking Shrinks Brain and Increases Alzheimer's Risk

A groundbreaking study conducted by the Alzheimer's Association and Boston University School of Medicine, published in the Journal of Aging and Health, reveals that aging alone does not necessarily lead to cognitive decline or increased risk of neurological disorders. Instead, lifestyle choices and genetic predispositions play a significant role in determining brain health in older adults. Additionally, the study has the potential to reshape the way we approach brain health in older adults. Furthermore, recent research from the Washington University School of Medicine confirmed that smoking one pack daily led to decreased brain volume compared to non-smokers, with each additional year of smoking resulting in more brain shrinkage, increasing the risk of dementia.
