Psychiatric Symptoms in Refractory Epilepsy During the First Year After Surgery.

ABSTRACT: Psychiatric morbidity in drug-resistant epilepsy is frequent. Surgery is the best therapeutic alternative for treating seizures, but the current evidence concerning the effects of surgery on psychiatric disorders (PDs) is inconclusive. We aim to clarify surgery's role in long-term PDs. Using a prospective controlled study, we analyzed the psychopathologic outcomes of patients with drug-resistant epilepsy, comparing those who underwent surgery to those who did not due to not being suitable. Surgical candidates were paired (n?=?84) with the immediately following nonsurgical candidates (n?=?68). Both groups continued their usual medical treatment. We studied psychiatric changes for each group and analyzed de novo and remission cases. The assessments were made during the presurgical evaluation, and at 6 months (6-M) and 12 months (12-M) after surgery. Finally, we determined associated factors for postsurgical PDs. At 12 months, using the Hospital Anxiety and Depression Scale (HADS), anxiety improved in both groups (p?=?0.000), while depression improved only in the surgical group (p?=?0.016). Moreover, all symptom dimensions on the Symptom Checklist-90-R (SCL-90), as well as severity, distress, and total symptoms, decreased only in the surgical group. These ameliorations reached not only statistical significance but also clinical significance for depression (HADS) (p?=?0.014) and the interictal dysphoric disorder (p?=?0.013). The main predictors for PDs after surgery were as follows: the presurgical and 6-month psychiatric symptoms, the absence of surgery, seizure outcomes, and some antiepileptic and psychiatric drugs. This study provides evidence that surgery for epilepsy could have a role in improving some symptoms of psychiatric disorders 12-M after the surgery.

Project description:BackgroundIndividuals with epilepsy who cannot be adequately controlled with anti-epileptic drugs, refractory epilepsy, may be suitable for surgical treatment following detailed assessment. This is a complex process and there are concerns over delays in referring refractory epilepsy patients for surgery and subsequent treatment. The aim of this study was to explore the different patient pathways, referral and surgical timeframes, and surgical and medical treatment options for refractory epilepsy patients referred to two Tertiary Epilepsy Clinics in New South Wales, Australia.MethodsClinical records were reviewed for 50 patients attending the two clinics, in two large teaching hospitals (25 in Clinic 1; 25 in Clinic 2. A purpose-designed audit tool collected detailed aspects of outpatient consultations and treatment. Patients with refractory epilepsy with their first appointment in 2014 were reviewed for up to six visits until the end of 2016. Data collection included: patient demographics, type of epilepsy, drug management, and assessment for surgery. Outcomes included: decisions regarding surgical and/or medical management, and seizure status following surgery. Patient-reported outcome measures to assess anxiety and depression were collected in Clinic 1 only.ResultsPatient mean age was 38.3 years (SD 13.4), the mean years since diagnosis was 17.3 years (SD 9.8), and 88.0% of patients had a main diagnosis of focal epilepsy. Patients were taking an average of 2.3 (SD 0.9) anti-epileptic drugs at the first clinic visit. A total of 17 (34.0%) patients were referred to the surgical team and 11 (22.0%) underwent a neuro-surgical procedure. The average waiting time between visit 1 to surgical referral was 38.8 weeks (SD 25.1), and between visit 1 and the first post-operative visit was 55.8 weeks (SD 25.0).ConclusionThe findings confirm international data showing significant waiting times between diagnosis of epilepsy and referral to specialist clinics for surgical assessment and highlight different approaches in each clinic in terms of visit numbers and recorded activities. A standardised pathway and data collection, including patient-reported outcome measures, would provide better evidence for whether promoting earlier referral and assessment for surgery improves the lives of this disease group.
