The movement-related potential in children with migraine and tension-type headache.
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.
