What's happening

At first, you might be able to meet your loved one's needs yourself. This might last months or even years, depending on how quickly the disease progresses and your own mental and physical health. Eventually, however, your loved one will need more help with everyday tasks, such as eating, bathing and toileting.

And just as the physical demands of caregiving increase, so can the emotional toll. Challenging dementia-related behaviors can strain the coping skills of even the most patient and understanding caregiver.

The sustained stress of caregiving also can weaken your immune system. You might eat and sleep poorly and have trouble setting aside time for yourself. Caregiving might also increase your risk of depression. Before you know it, you're so busy caring for your loved one that you could drift away from your family and friends — at a time when you need them the most.
