--for neural symptoms that stem from damage to the nerves in the peripheral regions; that is, those outside the brain and spinal cord. These can range from problems with the spinal nerve roots (the first nerves outside the spine--this is termed "radiculopathy" from the Latin "radic", or root), to problems way down the line at the tips of fingers and toes, to anywhere in-between.

There are over two hundred KNOWN causes of peripheral nerve compromise, and there are probably almost as many currently unknown causes, particularly autoimmune and toxic ones, that have not yet been precisely identified.

Part of the problem is that investigation into cause can be very long, expensive, and baffling--neural symptoms from brain/spine problems and those from peripheral nerve problems can be exactly the same--so one really needs neurologists with this particular area of expertise.

Having had surgery for brain aneurysms suggests your symptoms may stem from there, but certainly a wide-ranging work-up is called for.

These have been together to be as comprehensive a list of tests for causes of neural symptoms as current medical knowledge can imagine.
