Which of the following is considered a hallmark feature of migraine in children?

The hallmark feature of migraines in children is often characterized by shorter-lasting attacks compared to those typically seen in adults. In pediatric patients, the duration of migraine attacks can vary, but they tend to be more brief, usually lasting from one to two hours, whereas adults may experience headaches that last much longer, often 4 to 72 hours. This distinction is important as it highlights how migraines can present differently in children.

While unilateral headache, visual aura, and increased vomiting can be associated with migraines, they are not as classically defining of pediatric cases as the shorter duration of the attacks. Many children may also experience bilateral headaches, and the presence of aura is less common in pediatric populations. Understanding that migraines in children may have different typical features helps in their diagnosis and management.
