I am trying to save my wife. She is 62, nonsmoker, nondrinker. She is in late stages of NASH(hereditary) but numbers are all good and edema is not out of control. She is, however, experiencing loss of fine motor skills in arms and hands bilaterally, especially upon waking . It gradually improves after waking but is still diminished throughout the day. And her gate and balance have made her where she must be guarded against falls and escorted. On good days she gets along well with cane. She has some sleep apnea but primary physician doubts it is of issue here. Serum ammonia was high but we think it is better now as confusion she was experiencing has improved. Any thoughts as to what this might be?
