Phantom spike-and-wave bursts during REM-sleep.
Phantom spike-and-wave bursts or 6Hz spike-and-wave bursts consist of brief bursts of spikes of very low amplitude with a repetition range of 5 to 7Hz. This pattern usually occurs bilaterally and synchronously during relaxed wakefulness, drowsiness or light sleep. Bursts disappear during deeper levels of sleep. We present the case of a patient in whom this pattern reappeared in REM-sleep. This observation confirms that the stage of REM-sleep is close to wakefulness or drowsiness and may contain EEG patterns that are seen in these stages.
