1.1 Migraine without aura Previously used terms:

Common migraine; hemicrania simplex. Description:

Recurrent headache disorder manifesting in attacks lasting 4-72 hours. Typical characteristics of the headache are unilateral location, pulsating quality, moderate or severe intensity, aggravation by routine physical activity, and association with nausea and/or photophobia and phonophobia. Diagnostic criteria: A. At least 5 attacks 1 fulfilling criteria B-D B. Headache attacks lasting 4-72 hours (when untreated or unsuccessfully treated) 2,3 C. Headache has at least 2 of the following 4 characteristics: 1. Unilateral location 2. Pulsating quality 3. Moderate or severe pain intensity 4. Aggravation by or causing avoidance of routine physical activity (e.g. walking or climbing stairs) D. During headache, at least 1 of the following: 1. Nausea and/or vomiting 2. Photophobia and phonophobia E. Not better accounted for by another ICHD-3 diagnosis. Notes: 1 One or a few migraine attacks may be difficult to distinguish from symptomatic migraine-like attacks. Furthermore, the nature of a single or a few attacks may be difficult to understand. Therefore, at least 5 attacks are required. Individuals who otherwise meet criteria for 1.1 Migraine without aura but have had fewer than 5 attacks should be coded 1.5.1 Probable migraine without aura . 2 When the patient falls asleep during a migraine attack and wakes up without it, duration of the attack is reckoned until the time of awakening. 3 In children and adolescents (aged \ 18 years), attacks may last 2-72 hours (the evidence for untreated durations \ 2 hours in children has not been substantiated). 1.2 Migraine with aura Previously used terms: Classic or classical migraine; ophthalmic, hemiparaesthetic, hemiplegic, or aphasic migraine; migraine accompagne´e; complicated migraine. Description: Recurrent attacks, lasting minutes, of unilateral fully reversible visual, sensory, or other central nervous system symptoms that usually develop gradually and are usually followed by headache and associated migraine symptoms. Diagnostic criteria: A. At least 2 attacks fulfilling criteria B and C B. One or more of the following fully reversible aura symptoms: 1. Visual 2. Sensory 3. Speech and/or language 4. Motor 5. Brainstem 6. Retinal C. At least 3 of the following 6 characteristics: 1. At least 1 aura symptom spreads gradually over 5minutes 4. At least 1 aura symptom is unilateral 2 5. At least 1 aura symptom is positive 3 6. The aura is accompanied, or followed within 60 minutes, by headache D. Not better accounted for by another ICHD-3 diagnosis. Notes: 1 When, for example, 3 symptoms occur during an aura, the acceptable maximal duration is 3 3 60 minutes. Motor symptoms may last up to 72 hours. 2 Aphasia is always regarded as a unilateral symptom; dysarthria may or may not be. 3 Scintillations and pins and needles are positive symptoms of aura. 2. Two or more aura symptoms occur in succession 3. Each individual aura symptom lasts 5-60 minutes 1
