My mother in law's memory has gotten worse in the past few months to the point that she sometimes does not remember her husband. This scares her. In these instances she does still remember my husband and our phone number. We are grateful when she does this as it gives us a chance to reassure her and even get in the car and come over. Fortunately my father in law is still very sharp but it is painful for him to go through this. He adores her and would do anything for her but feels helpless during these times.
