It's useful to keep a health journal so you can ensure that your loved one's health care team is able to provide the best care possible. By keeping track of day-to-day health information that only you may observe, you can provide valuable information to your loved one's health care team. A journal also makes it easy to record information about Alzheimer's disease and other conditions your loved one may have, so you can make the most of your time at appointments and be sure not to forget anything.
