My mother had a knee replacement about 5 years ago. (Not sure if related but this is when it started) I went to the recovery room after when she first woke up. The doctor said she received blood from the blood bank because she lost allot. When I spoke to my mother she stuttered! I thought to myself what caused that the anesthesia? So I figured it would just go away. Well, ever since then she stuttered a little once in a while talking. Maybe, once in a conversation or not at all. In the course of 5 years this turned into no speech at all. loss of expression and blank stairs. She lost the ability to walk almost totally but still gets around with a walker. She now has trouble feeding herself and moves slow and stiff. She also in the last 6 months has problems controlling her bladder. Last but not least she looks to have problems swelling and coughs allot. When she drinks fluid it is like it goes down the wrong way many times and she coughs. This was NOT sudden like a stroke but slow over 5 years. Three neurologists and surgeons have scanned her and looked her over every way they could but can not figure it out. They also installed a Shunt but said they did not think she really needed it but hoped this would do some good. It does not look to have done much of anything and has been there for about 2 years now. She now speaks Zero words and can only make some sounds. Any one have a clue what is happening to her?
