Electroencephalogram and brainstem auditory evoked potential in 539 patients with central coordination disorder

2008 
BACKGROUND: Electroencephalogram (EEG) and brainstem auditory evoked potential (BAEP) are objective non-invasive means of measuring brain electrophysiology. OBJECTIVE: To analyze the value of EEG and BAEP in early diagnosis, treatment and prognostic evaluation of central coordination disorder. DESIGN, TIME AND SETTING: This case analysis study was performed at the Rehabilitation Center of Hunan Children's Hospital from January 2002 to January 2006. PARTICIPANTS: A total of 593 patients with severe central coordination disorder, comprising 455 boys and 138 girls, aged 1-6 months were enrolled for this study. METHODS: EEG was monitored using electroencephalography. BAEP was recorded using a Keypoint electromyogram device. Intelligence was tested by professionals using the Gesell scale. MAIN OUTCOME MEASURES: (1) The rate of abnormal EEG and BAEP, (2) correlation of abnormalities of EEG and BAEP with associated injuries, (3) correlation of abnormalities of EEG and BAEP with high risk factors. RESULTS: The rate of abnormal EEG was 68.6% (407/593 patients), and was increased in patients who also had mental retardation (P CONCLUSION: Central coordination disorder is often associated with abnormal EEG and BAEP The rate of EEG or BAEP abnormality is positively associated with the size of the brain injury. Asphyxia is a high risk factor for abnormal EEG in central coordination disorder. Jaundice and intrauterine infection are high risk factors for abnormal BAEP in central coordination disorder.
