Absence seizures during hyperventilation with horizontal head jerking (EEG)

EEG in 5-year-old boy shows generalized spike-wave ictal discharge similar to childhood absence epilepsy preceded by high amplitude delta-theta waves in centroposterior regions. The discharge immediately starts with rhythmic horizontal head jerking. The boy’s eyes remained open with a vague look and no response. His head turned to the right side while jerking. He recovered after about 12 seconds. (Contributed by Dr. Athanasios Covanis.)
