While further work is needed, much has been done to develop the scientific basis for geriatric nursing. Over the last few decades, research has identified conditions commonly seen in older adults, as well as needs and problems specific to that population. Current research addresses broad topics such as family caregiving, functional status, exercise, depression, dementia, delirium, mental health, and elder abuse, as well as specific conditions, such as incontinence, pressure ulcers, and hypertension.
