Hi @lindakbe - I'm wondering if your friend has any close family members you can talk to about the changes you've observed. Does your friend express any concern for herself about what is going on? That might open the path to a suggestion that she see her doctor. Is she still able to manage her home and surroundings okay? Is she safe where she is? I observed behavioral changes in my husband for six months. With his permission, I wrote them down and sent a letter to his primary care doctor, who referred him to a neurologist. He had an MRI and neurpsychological testing which led to a diagnosis of Alzheimer's Disease. Later his doctor told me that the letter was so helpful because it gave him a sense of what was going on. Many times, patients in similar situations showed up for appointments with no explanation about why they were there. I wish you the best with this - she is fortunate to have such a good friend.
