Two cases of steroid dementia showing partial recovery during 2-year follow-up.

Cognitive dysfunction caused by steroids is suggested by these cases, although definitive diagnosis in these cases is not possible. It was partially reversible over the course of a few years, but some functional loss remains. Cognitive function should be assessed appropriately before, during, and after steroid treatment. Detailed differential diagnosis of neurodegenerative disorders and longitudinal follow-up is required when cognitive dysfunction is observed after initiation of steroid therapy.
