MRI test can show: If you have neuropathy, the MRI tests will be normal. Neuropathy is determined with nerve conduction tests (sometimes called EMG). There are many causes of neuropathy besides diabetes. These include vitamin B12 deficiency and heavy alcohol use. MRI tests are often ordered to assess for numbness, just not numbness caused by neuropathy. ...Read more

Nerve Damage (Definition)

A complete nerve transection will leave an area totally numb. The distribution of the numbers depends upon where the nerve was cut. A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend ...Read more

Would an MRI of the brain and cervical spine be able to yield info about the source of peripheral neuropathy? Or would lumbar spine be more approp?

Would an MRI of the brain and cervical spine be able to yield info about the source of peripheral neuropathy? Or would lumbar spine be more approp?

Lumbar puncture (LP): If peripheral neuropathy is the diagnosis, then a lumbar puncture wd prob be higher yield than an MRI. MRI only detects anatomical abnormalities. Peripheral neuropathy is caused by a systemic condition - infection, metabolic (diabetes), auto-immune, etc. It is a functional (not anatomic) problem. In the right context, a LP cd show evid 4 viral, MS, & other causes. MRI will likely yield nothing. ...Read more

I have been taking Neurontin (gabapentin) for peripheral neuropathy because i was told it will stop nerve damage from progressing. Is that true ?

I have been taking Neurontin (gabapentin) for peripheral  neuropathy because i was told it will stop nerve damage from progressing.  Is that true ?

Neurontin (gabapentin): Neurontin (gabapentin) is commonly used to treat nerve pain in peripheral neuropathy. It does not stop the progression of the damage. That requires understanding the cause of the pain and treating that cause. ...Read more

Why is trigeminal neuraligia considered a peripheral neuropathy even though it is a problem with a cranial nerve not a peripheral nerve?

Is there a special treatment for peripheral neuropathy and nerve damage caused by inhalation of cleaning chemicals.

Neuropathy: No specific treatments at this time. The treatment usually begins with medications in the antidepressant or anticonvulsant categories. A nerve test Is performed to determine the type of peripheral nerve and the extent of the injury. Transcutaneous electrical nerve stimulation and spinal cord stimulation may help too. Compound creams applied to the affected areas can provide significant relief. ...Read more

With peripheral neuropathy, what conditions could cause damage to both axons and myelin as shown in nerve conduction tests? And can it be reversed?

With peripheral neuropathy, what conditions could cause damage to both axons and myelin as shown in nerve conduction tests? And can it be reversed?

Brief explanation: Most neuropathies affect myelin coverings (Schwann cell), but an advancing axonal neuropathy can secondarily affect the myelin. This is not simple, and you would be far better served by a Concierge consult, and/or find an experienced Medical School neurologist. Reversibility depends on causes and appropriate therapy. ...Read more
