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!
Several tests before we managed to reach a diagnosis of "atypical Parkinsonism", which is an umbrella term for a number of more specific neurological disorders which all carry symptoms much like PD but are also in many ways different. Only a neurologist who specializes in movement disorders can make that determination. Have her seen by her PCP, do explore other possible explanations, but also insist on a referral to a qualified neurologist. IF something neurological is going on then the sooner it's caught the better. Good luck!
But also follow up on what is actually going on. Anything from a urinary tract infection to the medications she's taking could be causing these symptoms so she needs medical attention. Then, when you know what is going on you'll be more able to know what to expect.
Take care,
Carol
