It is almost impossible for a doctor to give medications for neurological symptoms unless she/he knows the cause. Medications can be incredibly expensive and worthless or even worse, damaging, if not treating the correct cause.
Palative meds are sometimes given such as benzodiazepines or antidepressants but don't treat the symptoms, only the emotional distress of the symptoms. This can be frustrating to the patient who sees this as an expression from the doctor of not taking their symptoms seriously; but in actuality it may be the only thing they can do at the moment until they are able to narrow down many, many causes of the problem. Benzodiazepines have the added benefit of helping to alleviate muscle spasms and insomnia. Just be careful if you take these though that the neuro knows you are taking them as it may mask those symptoms that help him make a diagnosis.
