Q. Recently my brother was in the hospital, and he became very confused and agitated. He is normally a pretty sharp man, but the things he was saying made no sense at all, and he was very anxious. We thought he was going to have to go a nursing home. He has since returned to his usual self, and the doctor said he had delirium. Is this condition the same as dementia? Could this happen again? How can we prevent it from occurring? -Debbie G.
Debbie, Delirium is a sudden, temporary onset of an altered mental state. The length of the episodes can vary from days to weeks.
