However, people who consumed one to six diet sodas daily were 2.6 time more likely to experience an ischemic stroke.
Although the researchers took age, smoking, diet quality, and other factors into account, they could not completely control for preexisting conditions like diabetes, which may have developed over the course of the study and is a known risk factor for dementia.

The study, which looked at ten years" worth of data from more than 4,300 people, indicates that people need to look beyond the word "diet' when making drink choices.
While the findings do not prove that diet drinks damage brains, they support other studies that show people who drink them frequently tend to have poorer health. The researchers measured the participants' beverage intake at three points over seven years.
The study didn't identify different types of artificial sweeteners, which vary greatly from product to product, and nor did it explain why drinking ASBs might bring on stroke and dementia.
However, an increasing number of studies are finding that artificially sweetened products are far from innocent.
Used statistical models adjusted for various risk factors, researchers found that people who drank at least one artificially-sweetened beverage a day were three times as likely to develop ischemic stroke and 2.9 times as likely to develop Alzheimer's disease dementia.More news: Samsung Elec's Q1 OP near $9 bn on strong chip sales
While the current findings suggest a link between regular intake of artificially sweetened drinks and stroke and dementia, the researchers stress their study is purely observational, so no conclusions can be drawn.
Scientists found those having one or more artificially sweetened drinks a day were nearly three times more at risk than those consuming fewer than one a week.
He also warned that although no relation was found between sugary drinks and an increased risk of dementia or stroke, consumers should not consider them a "healthy option".
The researchers also showed that both sugar and artificially-sweetened drink consumption has increased blood pressure, blood sugar, and abnormal cholesterol.
The researchers have cautioned against using sugary beverages or even diet sodas.
(Boston)-Data from the Framingham Heart Study (FHS) has shown that people who more frequently consume sugary beverages such as sodas and fruit juices are more likely to have poorer memory, smaller overall brain volumes and smaller hippocampal volumes-an area of the brain important for memory. "But it does highlight a worrying association that requires further investigation", said Dr James Pickett, head of research at Alzheimer's Society.
"They may have a role for people with diabetes and in weight loss, but we encourage people to drink water, low-fat milk, or other beverages without added sweeteners".
Dr Mary Hannon-Fletcher, the Head of Health Sciences at Ulster University in the United Kingdom, said that although the research was good, the methods of getting the data had limitations.
"In fact, based on the evidence, Public Health England is actively encouraging food and drink companies to use low-calorie sweeteners as an alternative to sugar and help people manage their weight".
