Profiling the evolution of depression after epilepsy surgery

Abstract

The findings of this study confirm high rates of major depression before and after epilepsy surgery, the etiology of which is multifactorial. They highlight the need for thorough assessment and diagnosis before surgery, as well as the provision of routine follow-up and psychological support, particularly early after surgery. When estimating level of risk for depression, patients should be counseled about the role of both neurobiologic and psychosocial factors. Before surgery, these include a family history of psychiatric illness and financial dependence, whereas poor family adjustment to life after surgery and a patient preoperative history of depression were risk factors for postoperative depression. Finally, disruption to mesial temporal structures known to play a role in mood via MTR may place patients at increased risk of new-onset depression after surgery.
