Dear Rose Mary,
It is understandable that you are concerned over your mother's emotional state. Mood changes are a very common symptom of Alzheimer's disease and if she seems to become emotional over anything, it is possible that something benign could trigger your mother to react this way. You mentioned that your mother wants to go somewhere and be with her sisters or other people. Perhaps she wishes to do so because her sisters may provide comfort and security, a feeling that individuals (especially those with Alzheimer's disease) yearn for. It is not always easy for a caregiver to tell what is causing this to happen, but a caregiver has all the power to respond to it appropriately. The fact that you let her walk around until she tires out is very important. Although she may not have been able to go elsewhere at the time, just letting her "be" is so valuable. By allowing her to roam around the house, you are giving her the chance to collect her thoughts, release pent-up energy, and in a sense, "walk it off". By not restricting her freedom, you are meeting her "where she's at." You did a good thing by sending a message that it's ok for her to get emotional, and that you are there to support her through it until she feels better.
Alzheimer's disease is a complex, challenging illness, and can often be a struggle for caregivers to deal with. It is not uncommon for individuals with this disease to experience a variety of symptoms and behaviors, which can sometimes manifest differently from day to day. It seems as though your mother expresses a number of such behaviors, and you are, to your credit, working as hard as you can to try to find the right answers. It is clear how much you love your mother, and it is commendable that you are doing everything you can to support her through this difficult time. However, as a caregiver and loving daughter, your needs are just as important, and you should not minimize the value of caring for yourself. Judging by your previous posts, it appears as though you may benefit from a weekly support group. A support group can not only offer useful advice on a number of issues that you are experiencing, but can help you as a dedicated caregiver to accept and work through this complicated process. You can access this support either in person, or over the phone, and profit from the suggestions of others who are going through something similar. I encourage you to contact the Alzheimer's Foundation of America at (866) 232-8484 for more information. We are looking forward to hearing from you.
