Diagnostic criteria:
- At least five attacks of intense nausea and vomiting, fulfilling criteria B and C
- Stereotypical in the individual patient and recurring with predictable periodicity
- All of the following:
- nausea and vomiting occur at least four times per hour
- attacks last for ≥1 hour, up to 10 days
- attacks occur ≥1 week apart
- Complete freedom from symptoms between attacks

Comments:
1.6.1.1 Cyclic vomiting syndrome is typically a self-limiting episodic condition occurring in childhood, with periods of complete normality between episodes. The cyclic nature is the hallmark, and attacks are predictable.
This disorder was first included as a childhood periodic syndrome in ICHD-II. The clinical features of this syndrome resemble those found in association with migraine headaches, and multiple threads of research over the last years have suggested that 1.6.1.1 Cyclic vomiting syndrome is a condition related to migraine.
