Your post brought a smile to my face Sammy. At least your friend is getting the chance of hope. Please let us know the results of the testing
Yes, she can have both. But NPH also mimics ALZ so it could be the NPH that is causing the dementia symptoms you see. If it is NPH and the shunt is implanted, you should see improvements. The degree of the improvements will depend on how early they caught it and on her response to the shunt.
Yes, it is confusing. You will only know the level of improvement when it happens. I was amazed at the improvement my friend's step father showed when he got his shunt... especially in his ability to ambulate. His cognitive ability did improve but not back to his "normal". Since then he has declined but it appears that he has Vascular Dementia like Dad. He has been through the same heart bypass, stint, heart med routine as Dad. When blood is not flowing in the heart and legs then it is probably not flowing in the brain either. So that would explain the recent decline. Yet, he is still better than he was before the shunt for NPH was implanted.
This is one of those situations that you can't get clear cut answers until it happens. Just know that if NPH is the problem... there will be some improvement with the shunt!! I hope it is major improvements!!
I am saying a prayer for her today and hope it goes well for her.
