Prognosis The prognosis is determined by the particular cause of the autonomic neuropathy. In most cases the course is one of gradual progression. In the case of diabetes mellitus the prognosis is improved with good control of diabetes. [patient.info]

[…] committee stated that there was not enough evidence supporting efficacy of the drug, and requested additional clinical trials. [9] In August 2018, the FDA approved patisiran, an siRNA -based treatment, at an expected cost of up to 450,000 per year. [10] Prognosis [en.wikipedia.org]

Lightweight lower leg braces, special shoes or shoe inserts can help prevent ankle sprains and maximize independence. Surgery may be suggested to correct foot deformities. [peripheralneuropathycenter.uchicago.edu]

Leg braces prevent ankle sprains and improve walking ability. Surgery: For some people, surgery can help prevent or reverse foot and joint deformities. Pain management: Pain-killing drugs may be prescribed for people who have severe pain. [hnf-cure.org]

Since foot disorders are common with neuropathy, precautions must be taken to strengthen these muscles and use preventative care and physical therapy to prevent injury and deformities. [en.wikipedia.org]
