If the person in your care is in good health, you may not be thinking about her possible need for a conservatorship, or adult guardianship. But if you're considering this step, you're not alone. The unfortunate truth is that many older adults have long periods toward the end of life when they're not able to make decisions for themselves -- due to Alzheimer's or other forms of dementia, a stroke, an accident, or some other serious medical condition. If the person has an advance health care directive , the decision-making about her medical care, if she becomes incapacitated, may already be provided for. If she has a durable power of attorney for finances , there will be someone to take care of money matters.
