How do i know if i have guilain barre syndrome for certain? i had a ssep test performed. will this determine gbs? my neurosurgeon says i have it but my neurologist disagrees and blames my symptoms on a narrowing below my c4/c5. while they are playing pi

An : An ssep test measures how long it takes for signals to get from the ankles and wrists to the areas in the brain that control feeling. The test that is more specific for diagnosing neuropathy is the EMG test. Guillain-barre syndrome is usually a self limited neuropathy that comes on fairly rapidly and often resolves by itself. One of the first changes in the nerve test is slowing of the f wave which is a wave measured by stimulating a nerve and looking at a signal that occurs when the signal reaches the spinal cord and bounces back a response. A narrowing below c4/c5 can compress your spinal cord and interrupt some pathways that control feeling but there are other symptoms such as urinary problems that appear and the physical examination is very different.Gbs is treatable medically. I think you should get a second opinion.

EMG and LP: Guillain barre is diagnosed by history, examination findings, emg/nerve conduction studies and spinal tap looking at cerebrospinal fluid.
