What did the brand new research contain?
The analysis, carried out by Carol Coupland, a professor of medical statistics in major care on the University of Nottingham in England, and colleagues, evaluated anticholinergic medication prescribed to just about 285,000 individuals age 55 and older. About 59,000 of them had a prognosis of dementia. The data got here from a database of medical information from sufferers in additional than 1,500 common practices in Britain, the authors mentioned.
Researchers regarded on the medical information of sufferers who had been recognized with dementia and examined the medication that they had been prescribed from 11 years to at least one yr earlier than their prognosis. They in contrast their medicines throughout that time-frame with these of individuals who didn’t have a prognosis of dementia. They recorded which of 56 anticholinergic medicines individuals had been prescribed, and at what dose and the way lengthy. They accounted for components like physique mass index, smoking, alcohol consumption, different medical situations and use of different medicines.
