Heavy smokers ‘at increased risk of dementia’
Baku, October 26 (AZERTAC). Heavy smokers with a 40-a-day habit face a much higher risk of two common forms of dementia, a large study shows, according to BBC News.
The risk of Alzheimer`s is more than doubled in people smoking at least two packs of cigarettes a day in their mid-life.
The risk of vascular dementia, linked to problems in blood vessels supplying the brain, also rose significantly.
The US study, looking at over 21,000 people`s records, is published in the journal Archives of Internal Medicine.
The link between smoking and Alzheimer`s has already been suggested - but this is one of the biggest studies looking at how smoking in mid-life affects dementia risk decades later.
