Mood disturbance is a common comorbid condition of temporal lobe epilepsy before and after surgery. Suicide is more frequent in patients with epilepsy than in the general population. As suicide is a major issue in both epileptic and depressive patients, it is critical to treat aggressively any psychiatric illness with suicidal ideation. We describe two patients who, after temporal lobe surgery, developed a serious bipolar disorder that necessitated electroconvulsive therapy (ECT), despite better seizure control. Unfortunately they were not able to commit to a regular treatment plan with their psychiatrists to prevent a suicide. These patients underwent a course of ECT treatments. After the ECT regimen, acute suicidal intent remitted and was replaced by chronic suicidal ideation without active intent or plan. The patients were then able to commit to a treatment plan regarding their medications and control visits. These cases represent the safe utilization of ECT as a rapid and effective treatment option for bipolar disorder with suicide ideation following epilepsy Surgery. Patients and parents should be advised about possible psychiatric disturbances and suicide risk after epilepsy surgery, especially in the presence of a temporal lobe epilepsy, even when seizure control is achieved postoperatively.
