Caring for someone with Alzheimer's disease or another kind of dementia is a long, demanding, and emotionally draining experience. There are more than 16 million people caring for someone with dementia in the United States, and many more across the world. Because there is presently no treatment for Alzheimer's or dementia, your caregiving and support are typically the most important factors in improving your loved one's quality of life. As you see your loved one's memories fade and skills deteriorate, caring for someone with Alzheimer's disease or dementia might feel like a series of grieving experiences. Dementia causes people to change and behave in unexpected ways, which can be distressing or unsettling. Both caregivers and their patients may experience feelings of bewilderment, irritation, and despair as a result of these changes.
