A Finnish registry study found that hospital-treated cystitis and unspecified bacterial infections are linked to a higher risk of dementia in older patients. Analyzing data from over 62,000 dementia cases and approximately 312,000 controls, researchers observed that infections were associated with an increased dementia risk independent of comorbid conditions. Modest effects of these infections were noted, particularly in those with early-onset dementia, where additional infections like pneumonia also showed risks. The findings underscore the complex interrelations between infections and dementia progression.
