Durring his later years, my father was misdiagnosed with dementia by a house doctor in a private total care facility. This dx. was made w/o testing by a man who tended to give any elderly person who was a bit quirky as having some form of dementia. I wasn't buying it, called in his internal medicine doctor and met him at the facility for the exam. He took one look at Dad's med list, discontinued the steroid and asked me to call him in one week to discuss any changes. By that time, the worisome symptoms were gone.
