Headaches in children when to scan

Scanning is generally recommended for children with headaches accompanied by warning features such as early morning vomiting, worsening headache over weeks, new neurological symptoms (weakness, vision changes, unsteadiness), significant behaviour or personality change, or headache waking the child from sleep. Most childhood headaches, particularly migraine and tension-type headache, do not need imaging. A doctor will assess for these specific warning features when deciding whether a scan is warranted.

The vast majority of childhood headaches are due to common, benign causes such as migraine, tension-type headache, dehydration, poor sleep, eye strain, or viral illness. Less commonly, more significant causes such as raised pressure within the skull can be responsible, which is why certain warning features are specifically looked for. Stress, including school-related stress, is also a common contributing factor in children and teenagers.

Warning signs include headache that wakes the child from sleep or is worse first thing in the morning with vomiting, a headache that is progressively worsening over weeks, new weakness, vision changes, unsteadiness, seizures, or a significant change in behaviour or school performance. A headache accompanied by fever and neck stiffness also needs urgent assessment to rule out infection. Any of these features should prompt prompt medical review rather than watching and waiting.

No, most childhood headaches are benign and scanning every child would expose many unnecessarily to imaging without a clear benefit, particularly given radiation considerations with CT scans in children. Scanning is reserved for children with the specific warning features associated with a higher likelihood of a significant underlying cause. Doctors use established guidelines to identify which children genuinely need imaging.

Most childhood headaches, particularly migraine and tension-type headache, are managed with simple pain relief, good sleep and hydration habits, stress management, and identifying and avoiding specific triggers where possible. Preventive treatment may be considered for frequent or significantly disabling migraine. A paediatrician or paediatric neurologist can advise on more specific management if headaches are frequent or hard to control.

Headaches, including migraine, are actually quite common in children and teenagers, and most have a benign cause that improves with simple management. A minority of childhood headaches relate to a more significant underlying cause, which is why doctors specifically ask about and look for warning features. Getting an accurate assessment, rather than assuming the worst or dismissing symptoms, is the appropriate approach for any parent.

Childhood migraine typically follows a recognisable pattern of throbbing headache, often with nausea and light sensitivity, that comes and goes, without progressive worsening or new neurological symptoms between episodes. Headaches needing urgent scanning tend to show a different pattern: progressive worsening, morning vomiting, waking the child from sleep, or new neurological signs. A doctor’s assessment of the specific pattern and any accompanying features is the most reliable way to distinguish between the two.

See a doctor if your child’s headaches are frequent, severe, or significantly affecting school or daily activities, or if you notice any of the specific warning features described above. A private paediatric or paediatric neurology assessment can typically be arranged within about one to two weeks. Seek emergency care for a sudden, severe headache with vomiting, neurological symptoms, or if your child seems significantly unwell.
