I have hereditary peripheral neuropathy with a component of autonomic neuropathy. What helps me tremendously is alpha lipoic acid. It is routinely given to people diagnosed with neuropathy in Europe but it seems like getting the medical community in the U.S. awake to its value is difficult.
My symptoms were nearly body-wide with both me and my doctor very concerned. We'd heard about alpha lipoic acid so I decided to give it a try. I take the recommended dosage 300 mg. in the morning and 300 mg. in the evening. I get mine from Vitacost by mail as they have the 300 mg. capsules and it is less expensive than I find otherwise.
A few weeks after I started taking it, I noticed a difference. My symptoms were lessening and they finally went down below my knees and the abdominal problems I was having disappeared. I kept taking it and a couple of months later noticed the symptoms coming back. I was discouraged but checked my pill containers. I set mine out in 3 week intervals in the weekly containers. I'd put the alpha lipoic acid in my evening pills but forgot to put it in the morning pills. I'd not had the 300 mg. in the morning for 2 weeks. I immediately put it in and soon my symptoms were gone again.
I don't know what it would do for others but it is worth a try. You do take it with food and if you have an allergy to sulpher, you can't take it as it is a sulpher compound. The body makes alpha lipoic acid but lessens with age. It is a highly active antioxident, helps control blood sugar, helps the liver, and rejuvenates other antioxidents like Vitamin C.
I saw your question in the Google Alerts and felt strongly enough about the subject to go through the hoops in signing up to be able to access the site so I could leave this information. I hope it helps.
I'm President of The Northern California Chapter of The Neuropathy Association. We have nearly 50 support groups in Northern California for people with neuropathy. Your brain and your spinal chord are your Central Nervous System. ALS is in this nerve structure. All the other nerves in your body are peripheral nerves. AMA says that all diseases and disorders in the peripheral nerves is called neuropathy. Among these nerves are sensory, motior, and autonomic nerves. Some people have problems with one of these sets. Others have problems with two or all. With over 100 causes, neuropathy is "the most common disease you've never heard of." We know that in California, the number of people diagnosed and undiagnosed with neuropathy approaches 3 million yet many peope have never heard of it.
