I am sorry to hear about your mother. It is very difficult o assess what could be wrong with your mother. She may also have suffered a stroke. The symptoms can also be side effect of drugs but loss of function of arms and legs can also be due to nerve compression in the upper spine. Several viral infections of the nerves like transverse myelitis or Gullian Barre syndrome is also a possibility. It is important to get proper investigations done like MRI of brain and neck, vitamin B12, EMG, nerve conduction study etc. Please discuss with a neurologist. Hope this helps. Take care!

Hi, I am so sorry your Mom is going through this, and I know the pain and distress this brings you and the family. When your mother was diagnosed with Huntington's Disease, was her DNA tested for the mutated gene that causes the disease? The results should give a CAG count that should offer some insight and confirm its a correct diagnosis. Also you mentioned all het siblings, did any of them ever display any symptoms. If it is HD it is very rare to have such a late onset and even more rare to deteriorate so quickly. I would urge you to continue to explore all possible causes with the Dr's. If they leave it as confirmed Huntington's Disease then my personal advice to you is to speak to a specialist regarding your own genetic risk that HD would imply. Whatever the cause, best wishes to your Mom & you. X
