Can bladder infection medications have caused memory loss?

A fellow caregiver asked...

Received three different bladder infection medications over a period of about three months for recurring bladder infection. Came out in rash on legs and arms from one prescription. About six weeks ago, suddenly developed memory forgetfulness when comes to people's names. Has not got any worse but not got any better. No other problems. Could this have been caused by prescription bladder infection medications?
