The researchers analyzed data from nearly 790,000 adults to determine whether changes in smoking intensity affect dementia risk. More than 90% of the participants were long-term smokers, with a mean age of 52 years.
By the next medical examination, approximately 15% of the participants had quit smoking completely, 22% had reduced the number of cigarettes and 16% had increased the number of cigarettes. According to the researchers, participants who quit smoking had a lower risk of developing dementia (8%), Alzheimer’s disease (6%), and vascular dementia (16%). Surprisingly, people who reduced the number of cigarettes they smoked per day by at least 50% or more had a 25% greater risk of developing dementia than those who continued to smoke heavily.
