Patient's question:
My child is four years old. At one year old, he had a seizure due to rotavirus fever of 39 degrees. At that time, his eyes were rolled back, his fingers were in a claw-like position, his feet were straightened forward, his hands were bent, his body was straight, he was unconscious, and the seizure lasted for about one minute. The doctor tried pressing the center of the tongue, but it didn't help. Finally, he was given intravenous diazepam and intramuscular phenobarbital, after which he returned to normal.Impressions:
1. Moderate abnormal EEG
2. Frequent occurrence of slow waves and spike-slow complexes in both spontaneous and induced leads
Doctor's answer:
Spikes: The skin surface appears sharp like a needle tip, mostly negative-phase waves, but can also be positive-phase, biphasic, or triphasic waves.Sharp waves: Typical sharp waves consist of a rapid ascending and a slower descending branch, resembling a sawtooth pattern.
Spike-and-slow wave complex: The waveform is formed, all negative-phase waves; typical 3 Hz spike-and-slow wave, a special waveform for absence seizures.
Sharp-and-slow wave complex: Composed of sharp waves and slow waves.
Multispike-and-slow wave complex: Composed of several spike waves and one slow wave.
High-amplitude spike-and-sharp wave disorganization: A unique waveform where high-amplitude spikes, sharp waves, multispikes, or multispike-and-slow wave complexes, as well as slow waves, appear chaotically and irregularly in both timing and location. Commonly seen in infantile spasms, indicating severe brain damage.
