New York: If you thought switching to diet soda can help you avoid the ill effects associated with sugary soft drinks, think again! Researchers have found that while drinking sugary beverages frequently may lead to poorer memory, daily intake of diet soda may increase the risk of stroke and dementia.

Both sugary and diet drinks correlated with accelerated brain ageing, according to the findings published in two separate studies.

People who drink sugary beverages frequently are more likely to have poorer memory, smaller overall brain volume, and a significantly smaller hippocampus -- an area of the brain important for learning and memory, said the study published in the journal Alzheimer's & Dementia.

A follow-up study, published in the journal Stroke, found that people who drank diet soda daily were almost three times as likely to develop stroke and dementia when compared to those who did not.

Scientists have put forth various hypotheses about how artificial sweeteners may cause harm, from transforming gut bacteria to altering the brain's perception of "sweet," but "we need more work to figure out the underlying mechanisms", said Boston University's Matthew Pase, who is lead author on the two studies.
