Many different types of dementia exist, and many conditions cause it. Mixed dementia is a condition in which brain changes of more than one type of dementia occur simultaneously. Alzheimer's disease is the most common cause of dementia, accounting for 60-80% of dementia cases. Dementia is not a normal part of aging.
