Traveling with a senior loved one with Alzheimer's or dementia is difficult enough. During the hot summer months, however, it's critical that you add one more thing to your list of things you have to pay attention to: avoiding dehydration. Seniors with Alzheimer's and dementia have decreased senses of thirst and might not notice the heat, putting them at particular risk for problems of dehydration. Incontinence and the desire to avoid urination, worry about traveling, and canned air in planes can all make the potential for dehydration worse. As you're traveling, try some of these strategies for avoiding dehydration.
