A case of ciprofloxacin-induced acute polymorphic psychosis with a distinct deficit of the executive functions

摘要

We present the case of a 45-year-old female patient who developed an acute polymorphic psychosis after treatment with the antibiotic ciprofloxacin. The patient showed a distinct neuropsychological deficit of the executivefunction. Comparing the psychopharmacological features of ketamine and ciprofloxacine we hypothesize that ciprofloxacine leads to psychosis similar to a ketamine induced psychosis. Our case report is unique not only because fluorquinolone induced psychosis has a very low incidence, but although because we were the first in obtaining a detailed neuropsychological testing.
