I was out with mom yesterday, at a parade, we had to walk a little distance in the street to get to our spot, I was very nervous that she would fall because she walks as if her mind is in a cloud. I've always got to hold onto her arm, so she doesn't trip going down or up a curb or trip on a rock, or walk too far into the street. Is this something that is normal for a person with Alzheimers? I'd like to take her out, but it seems there is a safety issue with her.
