My husband now cannot walk at all.. his legs are very stiff. Sadly his arms are also going the same way. He has no balance what so ever. He is 68 and this started three years ago on his return from a ski trip and has steadily worsened.We have been to two Neurologists and the conclusion is .. you are a Diagnostic Conumdrum ! What do you do with that ? He has had a brain and back scan a gene test for MND. It is not Parkinson’s. I really thought after research that it’s Lateonset Ataxia but what do I know ! He is well in every other way and on no medication other than Rivaxiban which is a blood thinner.We manage best we can with no help as we do not have a name for his condition so no support. So frustrating . I feel better for having written this to people who have similar problems !
