context_page_description: A migraine is a medical condition which usually causes a pounding, throbbing headache on one side of the head. The pain may be very bad and hurt so much that a person may have a hard time doing anything. While most people who have migraines get a headache, not everyone does. There are different kinds of migraines, and some do not cause a headache but do have other symptoms.
  Most migraines cause a headache and nausea and might make the person dizzy or very sensitive to bright lights or loud noises. Some people have "auras" before a migraine starts, which means their ability to see becomes different. They may see funny patterns, have blurry vision, or may not be able to see at all. Other senses can change before or during a migraine, and the person may sense funny smells or tastes. Migraines can last a long time. Migraines usually last between four and 72 hours.
  Migraines have been classified, based on how often they happen in a month: If a person has a headache for less than fifteen days, the migraine is called episodic migraine. If it happens more than fifteen days, it is called chronic migraine. Chronic means it happens over a long amount of time.
context_section_description: Childhood periodic syndromes are a group of migraine syndromes that children may have. When a child has one of these child periodic syndromes there is a greater chance that they will get one of the other, more common types of migraines when they become adults.
  Abdominal migraine is a kind of migraine which causes a very bad pain in the area of the abdomen, usually around the 'belly-button' which is called the periumbilical area. Abdominal migraine usually affects children starting at about age 7, but it may affect younger children and older children, and it may also sometimes affect adults.
  Benign paroxysmal vertigo of childhood (BPVC for short): (this means harmless dizziness, that happens again and again and happens suddenly) is a medical condition which occurs in children usually starting between two and five years of age; it often disappears by the age of eight. BPVC causes vertigo.
  Cyclic vomiting syndrome or cyclical vomiting syndrome (CVS), is a medical condition whose main symptoms are nausea and repeated vomiting. CVS happens more often in children, but it can occur at any age.
