Lateralized effects of migraine and ANS seizures after closed head injury.

ABSTRACT

Theoretical issues associated with memory, neurocognitive and noradrenergic mechanisms in posttraumatic migraine and dysautonomic complex-partial seizure disorders are reviewed, compared and discussed. Additionally, pretreatment Contingent Negative Variation (CNV) was recorded in a No-GO/GO reaction-time paradigm for 15 normal, and 18 posttraumatic migraine and seizure patients tested not more than three months postinjury. Normals demonstrated that CNV GO and NO-GO responses significantly differed. In both migraine and seizure patients GO and NO-GO trials did not differ significantly. In uncontrolled trials, it was noted that B-Blocker administration increased the difference between GO and NO-GO trials for both migraine and seizure patients over midline leads.
