Dementia is a serious loss of global cognitive ability that is more common in geriatric populations. It reduces the ability to learn, reason, retain or recall past experiences. Symptoms include mental and behavioral problems that affect quality of life for both the individual and their caregivers. Common causes of dementia include Alzheimer's disease, vascular dementia, traumatic brain injury, and hypoxic ischemic injury from temporary reductions in blood or oxygen supply to the brain. While lifestyle changes and medications have been proposed to prevent dementia, none have been reliably shown to be effective.
