Tests and diagnosisBy Mayo Clinic staff
To learn about the nature of your child's headache, your doctor will likely recommend the following steps:
- Headache history. Your doctor asks you and your child to describe the headaches in detail, to see if there's a pattern or a common trigger. Your doctor may also ask you to keep a headache diary for a time, so you can record more details about your child's headaches, such as frequency, severity of pain and possible triggers.
- Physical exam. The doctor also performs a physical exam, including measuring your child's height, weight, head circumference, blood pressure and pulse, and examining your child's eyes, neck, head, shoulders and spine.
- Neurological exam. Your doctor checks for any problems with movement, coordination or sensation.
If your child is otherwise healthy and headache is the only symptom, no further testing usually is needed. In a few cases, however, imaging scans and other evaluations are needed to pinpoint a diagnosis or to rule out other medical conditions that could be causing the headaches. These tests may include:
- Computerized tomography (CT). This imaging procedure uses a series of computer-directed X-rays that provide a cross-sectional view of your child's brain. This helps doctors diagnose tumors, infections and other possible medical problems that may be causing headaches.
- Magnetic resonance imaging (MRI). MRIs use radio waves and a powerful magnet to produce very detailed views of the brain. MRI scans help doctors diagnose tumors, strokes, aneurysms, neurological diseases and other brain abnormalities. An MRI can also be used to examine the blood vessels that supply the brain.
- Spinal tap (lumbar puncture). If your doctor suspects that an underlying condition, such as bacterial or viral meningitis, is the cause of your child's headaches, he or she may recommend a spinal tap (lumbar puncture). In this procedure, a thin needle is inserted between two vertebrae in the lower back to extract a sample of cerebrospinal fluid (CSF) for laboratory analysis.
