- Headache
- Early morning (sleep > hypoventilation > hypercarbia > incrreases CNS bloodflow > inreaced ICP)
- Effortless vomiting
- Cranial nerve palsies (especially 6th nerve)
- Headache
- Brainstem
- CN deficits (facial weakness, abducens palsy, dysphagia), ataxia

Differential Diagnosis
Pediatric Headache
