Even though "classic migraine" and "complicated migraine" may be diagnosed readily, "common migraine" may be easily confused with other types of vascular headaches. This differential diagnosis is of great importance for the appropriate choice of drug therapy. It is frequently stated that family history of migraine and history of motion sickness in childhood suggest that a periodic vascular headache is most likely of migrainous origin; although this statement applies to ophthalmoplegic and hemiplegic migraine, it is doubtful that it applies to common migraine. In fact, in a pilot study of patients with common migraine, we have observed that family history and history of mo tion sickness in childhood did not contribute to the diagnosis. Vestibular dysfunctions are frequently associated with migraine including the common type. Utilizing labyrinthine tests with the aid of electronystagmography, abnormalities of labyrinth function were demonstrated in 80% of patients with common migraine who had no history of vertigo or of other otological and neurological disorders.

The use of a transcutaneous nerve stimulator yielded positive results in a condition marked by involuntary movements (tremors and myoclonias) and dystonia. In the absence of clues to the pathophysiology of the myoclonus and dystonia, it is argued that transcutaneous stimulation induces an action on the neurotransmitters that inhibits neuromuscular function.
