    Caring for a Person With Dementia

    Dementia is a progressive loss of mental function due to certain diseases that affect the brain.

    The losses are substantial. Over time, all types of dementia will lead to loss of memory, loss of reasoning and judgment, personality and behavioral changes, physical decline, and death.

    But the course dementia takes can vary widely from person to person. It's influenced by many factors, including age and other conditions a person may have.

    Sixty to 80 percent of U.S. dementia cases are caused by Alzheimer's disease. That's about 5.3 million people. The next most common dementias are vascular dementia, or tiny strokes in the brain, and Lewy Body dementia where alpha-synuclein protein lodges in certain regions of the brain.

    The Three Stages of Dementia

    After dementia is diagnosed, it usually follows a three-stage, downward trajectory.

    In mild dementia, people may have difficulty remembering words and names, learning and remembering new information, and planning and managing complicated activities such as driving. They may also be experiencing sadness, anxiety, loss of interest in once pleasurable activities, and other symptoms of major depression.

    In moderate dementia, judgment, physical function, and sensory processing are typically affected. This can cause problems with personal hygiene, inappropriate language, and wandering. This stage -- when your loved one is able to get around but has poor judgment -- is physically and emotionally challenging for the caregiver.

    "My dad went from being Mr. Nice Guy to Mr. Obsessed. And things were always worse at night. He was energized and I was physically exhausted," says Robert Matsuda, a Los Angeles musician who worked full-time and cared for his father with Alzheimer's Disease for three years before recently placing him in a nursing home.

    As a patient moves from mild to moderate dementia, some home modifications that may include removal of throw rugs, installation of locks and safety latches, and the addition of a commode in the bedroom often need to be made.

    This is also the time when the palliative care team should be brought in to support the caregiver and help manage behaviors.

    "I was anxious at first, but when they showed me how to manage my dad's behaviors and started bringing services into our home -- the nurse, the home health aide -- it was like the cavalry arrived," says Matsuda.
