High amplitude slow waves. EEG showed high amplitude, 5-6 Hz and slow waves during the vomiting-free periods.

On EEGs performed at high amplitude, 5~6 Hz waves and slow waves (Figure 1) were evident but there were no sudden abnormal waves.
High amplitude slow waves correlated with vomiting. EEG with light symptoms. The increase in irregular waves correlated with vomiting. EEGs during severe vomiting could not be recorded properly.

After recording EEGs several times, a high amplitude slow wave was obtained while the patient was awake, which correlated with the vomiting (Figure 2).
Spike and wave complexes. Spike and wave complexes were recorded in T3 and F7 (temporal lobe) when the patient was drowsy.

When she was drowsy, spike and wave complexes appeared in the left temporal lobe (Figure 3) and repeated irregular slow wave bursts (Figure 4) were recorded.
Irregular slow wave burst. Irregular slow wave bursts were recorded repeatedly when the patient was drowsy.

When she was drowsy, spike and wave complexes appeared in the left temporal lobe (Figure 3) and repeated irregular slow wave bursts (Figure 4) were recorded.
EEG with administration of clonazepam. Slow waves decreased and changed to regular background waves four months after administration of clonazepam 1 mg.

Through the administration of from 1 to 2 mg clonazepam, background wave activity improved substantially (Figure 5) and vomiting episodes decreased, although the spike and wave complex was noted with drowsiness.
Changes in symptoms. Nausea decreased when the patient began to attend school for job training, although her symptoms worsened with fatigue. Insomnia and vomiting had resolved when she started her job. All symptoms had disappeared when she began to live alone and support herself.

When she began to live alone and support herself, all of her symptoms disappeared (Figure 6).
EEG after treatment. EEG after implementing biopsychosocial approaches. The patient had no vomiting and had discontinued medication. Irregular waves were evident in the background, although there were no high amplitude slow waves.

An EEG while the patient was awake and unmedicated showed irregular waves in the background and there were no high amplitude slow waves (Figure 7).
