Mom has not received a firm diagnosis, but she appears to be suffering from a Parkinsonian type disorder. She has trouble walking, and her mind is becoming clouded, for want of a better description. I know that there are certain things that happen as the mind ages, I see it in my father, but my mother-in-law seems to be having more severe reactions. She is disoriented and I need to know what is happening so I can explain to those around her as they do not have the patience with her that they should. Not that she is an easy person, to begin with... Thank you!
