1. this is not alzheimer's dementia.
most common cause of acute onset memory impairment in hospitalized elderly patients , associated with agitation is called delirium and is due to some medical condition for which person is hospitalized. hypoxia, electorlyte abnormalities, are major causes of delirium. this usually improves once the condition improves. Delirium is a sudden and severe change in brain function that causes a person to appear confused, disoriented, or to have difficulties maintaining focus, thinking clearly, and remembering recent events, typically with a fluctuating course. A urinary tract infection or dehydration can cause delirium in certain people.
managment is mainly conservative if no treatable trigger for delirium is found
Making sure the person gets enough to eat and drink (or providing nutrition through an IV, if needed)
pain management , avoiding discomfort
Making hearing aids and eyeglasses available at the hospital if the patient uses these at home
