Hello to all. I am the mother of an adult son with a VP shunt. He is 30 years old and has lived with a VP shunt for 28 years. He has had many shunt revisions and shunt replacements through the years. Last month he was involved in a side impact car wreck. He was taken to the ED and a shunt series was done showing the shunt to be intact. He has a NS appointment scheduled next month. What concerns me now is that he cannot tell where his feet are in the dark. (When driving at night he uses a flash light on the floor board.) I have researched this point and found that with the use of sight he is more comfortable with his location (proprioception) of his feet. The forum comments about ataxia related to shunt malfunctions, and the discussion of new types of shunts that are now available are of interest to me. My son has spascity from previous spinal cord and spine surgeries but is able to walk. This seems to have worsened since the accident and I wondered if this might be related to the shunt? I will attend the NS appointment with him, and I wanted to do a little research first. There doesn't seem to be a lot out of information out there. Hope to learn more in this forum. Does anyone have any good websites to share?
