ABSTRACT
Migraine is a complex syndrome commonly encountered in clinical practice and defined by the World Federation of Neurology as:
“A familial disorder characterised by recurrent attacks of headache widely variable in intensity, frequency and duration. Attacks are commonly unilateral and are usually associated with anorexia, nausea and vomiting. In some cases they are preceded by, or associated with, neurological and mood disturbances. All the above characteristics are not necessarily present in each attack or in each patient.”
