How and why do UTIs cause delirium and confusion in older people?

Answer 1

The real answer is that we don’t even know if this is the case. A systematic literature review couldn’t find a strong association between UTI and confusion. So it’s most certainly not a myth but I feel it’s wrong to answer your question, like many have done in this thread, like there’s a easy explanation to this.
