Descripción de una serie de 10 pacientes con cefalea hípnica: discusión de criterios diagnósticos

The criteria for hypnic headache of the new classification are best suited to the characteristics of these patients. Our results show the major changes in the criteria: pain is not always dull, headache frequency may be less than 15 days a month, and it can occur in people under age 50. There may be phonophobia or photophobia only, or both. Although it does not form part of the diagnostic criteria, the pain intensity in our series was higher than described.
