EEG Assessment in a 2-Year-Old Child with Prolonged Disorders of Consciousness: 3 Years’ Follow-up

الملخص EN

A 2-year-old girl, diagnosed with traumatic brain injury and epilepsy following car trauma, was followed up for 3 years (a total of 15 recordings taken at 0, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 14, 19, 26, and 35 months).

There is still no clear guidance on the diagnosis, treatment, and prognosis of children with disorders of consciousness.

At each appointment, recordings included the child’s height, weight, pediatric Glasgow Coma Scale (pGCS), Coma Recovery Scale-Revised (CRS-R), Gesell Developmental Schedule, computed tomography or magnetic resonance imaging, electroencephalogram, frequency of seizures, oral antiepileptic drugs, stimulation with subject’s own name (SON), and median nerve electrical stimulation (MNS).

Growth and development were deemed appropriate for the age of the child.

The pGCS and Gesell Developmental Schedule provided a comprehensive assessment of consciousness and mental development; the weighted Phase Lag Index (wPLI ) in the β-band (13–25 Hz) can distinguish unresponsive wakefulness syndrome from minimally conscious state and confirm that the SON and MNS were effective.

The continuous increase of delta-band power indicates a poor prognosis.

Interictal epileptiform discharges (IEDs) have a cumulative effect and seizures seriously affect the prognosis.
