People who have frequent or severe urinary tract infections may be at a greater risk of developing dementia, a study suggests. In fact, one recent study found half of dementia cases may be tied to modifiable lifestyle factors that form years before diagnosis. Now, researchers in Finland believe severe urinary tract infections (UTIs) and other bacterial diseases are associated with a higher risk of developing dementia years, or even decades, later. Of the 29 disorders, two were infections: UTIs and unspecified bacterial infections. There were several limitations to the study, including not having data on UTI treatments or investigating subtypes of dementia such as Alzheimer's disease or vascular dementia.
