What are the most common symptoms of a neurological problem?
New onset headaches could be a sign that would make you suspicious that there may be a neurological problem. As would changes in your behaviour, out of the blue. Difficulties with your thinking and memory, depending on your age; that would be something that you would worry about. Numbness someplace. Incoordination. Difficulty with your gait; bumping into things and so forth. Visual disturbances. Loss of hearing in one ear. Difficulty with your bladder control. Pain of unknown ideology; unknown cause. Now, with all of these, the primary physician would probably do some tests to make sure it's not something systemic. If you have the flu or if you have a urinary tract infection, you're going to have trouble with your urine as well. If you don't have a urinary tract infection and you're having problems with urgency, frequency, or whatever, they might send you to a urologist first, but if the urologist says, "Well, this looks like a neurogenic bladder," then you'd see a neurologist at that point. Certainly things like difficulty with your handwriting, difficulty with fine coordination, difficulty with your speech; all of those things would warrant that he send you to a neurologist.
