[Interest of EEG in full-term newborns with isolated unilateral ischemic stroke]

In full-term newborns, unilateral and recurrent clonic seizures which occur during the first 48 hours of life suggest an isolated unilateral ischemic stroke. These focal seizures are isolated, occuring during a short period, or make up a status epilepticus. Electroencephalogram (EEG) is a key tool for crisis and focal cerebral process diagnosis. It also allows to assess antiepileptic drugs effectiveness. But cerebral imaging is necessary to confirm vascular origin of the cerebral impairment. Hematologic data are also needful to look for a family thromphilia. Some particular unilateral EEG abnormalities could be associated with controlateral motor sequelae or long term behavioral problems. These findings may be used for prospective studies aimed at specifying possible links between EEG abnormalities and long term outcome.
