For decades, medical science has viewed dementia as a slow-burning fire fuelled by genetics and lifestyle. However, a recent, compelling study published in PLOS Medicine suggests that more sudden events occurring externally may shape the timeline of cognitive decline. Specifically, cases of severe cystitis (bladder infections) and even tooth decay have been identified as accelerants that could trigger a dementia diagnosis after a few years.
Looking at this through the lenses of biology, timing, and social care, we can begin to understand why a trip to the dentist or a quick recovery from a urinary tract infection (UTI) might be more vital to brain health than we ever imagined.
