My 26 year old son was diagnosed with ndph at mayo Rochester 3 years ago (after misdiagnosis at hopkins) he suffers greatly and has had to withdraw from the PhD program he was enrolled in due to inability to stand in a science lab and inability to concentrate. 2 questions. 1 – he also cannot stand or walk without the assistance of a cane. He says he doesn't always know what the ground is like under his feet (level or uphill, etc) Do any other ndph sufferers have this experience? And 2- Are there support groups, for him, and for me and his dad?
