Insights
Children with migraine and tension-type headache exhibit distinct brain activity differences. Specifically, their movement-related brain potentials (Bereitschaftspotential) showed unique negative patterns compared to healthy children.
Area of Science:
- Neuroscience
- Pediatric Neurology
- Clinical Electrophysiology
Background:
- Migraine is associated with altered brain activity, including elevated contingent negative variation (CNV).
- Movement-related potentials, such as the Bereitschaftspotential, reflect preparatory brain activity before self-initiated movements.
- Understanding these potentials in children with headache disorders is crucial for diagnosis and research.
Purpose of the Study:
- To investigate the Bereitschaftspotential in children diagnosed with migraine and tension-type headache.
- To compare the movement-related potentials of children with headache disorders to those of healthy controls.
- To explore potential differences in Bereitschaftspotential based on the presence of aura symptoms in migraine.
Main Methods:
- Electrophysiological recordings of movement-related potentials (Bereitschaftspotential) were obtained from 30 children with headache disorders and 16 healthy controls.
- Participants performed a self-initiated button-pressing task 80 times with their right index finger.
- Electrodes were placed at frontal and central scalp locations to capture brain activity.
Main Results:
- Healthy children displayed positive movement-related potentials at left and midline electrode positions.
- Children with migraine and tension-type headache exhibited negative movement-related potentials at midline leads, lacking lateralization.
- This negative shift in Bereitschaftspotential was more pronounced in children with migraine accompanied by aura symptoms.
Conclusions:
- Children with migraine and tension-type headache demonstrate abnormal preparatory brain activity during self-initiated movements.
- The observed negative shift in movement-related potentials may serve as a potential biomarker for headache disorders in children.
- Further research is warranted to elucidate the clinical significance and diagnostic utility of these findings, particularly regarding aura symptoms.
Abstract:
Migraine is characterized by an elevated contingent negative variation (CNV) in adults and children. In the present study the movement-related potential preceding self-initiated movements, the Bereitschaftspotential, was investigated in 30 children (mean age 12 years) who were suffering from migraine and tension-type headache and in 16 healthy age-matched controls. Children pressed a button 80 times with the right index finger while movement-related potentials were recorded from frontal and central electrodes. Whereas healthy children evidenced positive movement-related potentials at left and midline positions, children with migraine and tension-type headache showed negative movement-related potentials at midline leads without lateralization. Negativity was even more pronounced in cases of migraine with than without aura symptoms.

The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
