“The problem of headache disorders is much bigger than people imagine. It affects so many people, especially when you are talking about the most common conditions, migraine and tension-type headache. In my day-to-day clinical practice, I only see a very small fraction of the individuals who are living with these diseases. These people are the ones who are most severely affected by headache; they live with a very high frequency of headache or severe pain. But when you look at the global data, you understand that the people who seek out medical care are really just the tip of the iceberg.” – Andreas Husøy |
