Brief single-domain methods offer diagnostic performance for detection of dementia that is surprisingly close to that offered by cognitive batteries such as the MMSE. As a method of screening or as part of a diagnostic algorithm, brief single-domain tests may be an efficient first step in identifying cognitive impairment.

IntroductionAn eighty-one-year-old lady presented with mood changes within days of the commencement of prednisolone eye drops, which was prescribed following a cataract operation. She had a history of chronic schizophrenia, with one previous episode of hypomania in the early1990s. She was admitted to our institution on this occasion, with symptoms including elated mood, disinhibition, insomnia, pressured speech, flight of ideas and grandiose ideation. This was a distinctly different presentation from her previous relapses and the duration of this episode was prolonged. Her symptoms persisted despite an aggressive titration of psychotropic medications. After a review of her medication, the possible causal relationship between the prednisolone eye drops and manic episode was made. As the steroid eye drops were necessary following her eye operation, we allowed the completion of its course. Within days of its discontinuation, we saw a dramatIc improvement in her mental state and she was discharged. She currently remains in remission two months from the cessation of prednisolone.DiscussionThe postulation that the prednisolone eye drops triggered this manic episode can be substantiated by the clear observation that her symptoms completely resolved after the steroid course was completed. This appeared to be the one single factor which coincided with the emergence, maintenance and termination of her symptoms. Steroid-induced psychiatric symptoms are a well documented phenomenon, but are typically seen with higher doses and systemic administration of corticosteroids. This case report is of a rare presentation, and to our knowledge there are no similar cases described.
