A unique result?
One questioner asked if other medications used during the prodrome might yield similar results. Dr. Goadsby expressed doubt. “I think the evidence for other treatments is not terribly good. The triptan evidence is really poor. There is no randomized, placebo-controlled trial of a triptan explicitly in promontory symptomatology. There are randomized placebo controlled trials of triptans during the aura phase. The best one was the injected sumatriptan study, and it failed. So, as far as I can see from the randomized-controlled data, triptans don’t do this, and we don’t have good data for nonsteroidals and other therapies,” said Dr. Goadsby.
The researchers showed that you could treat a patient in advance of the headache to actually prevent the headache a significant number of times; it also reduced the prodromal events and it got patients back to normal functioning to a greater extent.
Dr. Goadsby was asked how many patients are typically able to identify prodrome periods on their own. He estimated that about one in three can do it initially. “I think if you teach people how to do this, it becomes very common. I would say four out of five people in my practice are able to talk about this, but you have to introduce the topic. They’ve had [prodrome symptoms], but they haven’t thought about it for a while. This is one of the things where headache doctors can offer real benefit in helping educate patients,” said Dr. Goadsby.
