Effectiveness of a Self-Management Program to Improve Cognition and Quality of Life in Epilepsy: A Pragmatic, Randomized, Multicenter Trial.

BACKGROUND AND OBJECTIVES: We conducted a multisite, pragmatic replication trial at 4 New England epilepsy centers to determine the effectiveness of Home-Based Self-Management and Cognitive Training Changes Lives (HOBSCOTCH) in a real-world setting and to assess feasibility of a virtual intervention. METHODS: HOBSCOTCH is an 8-session intervention addressing cognitive impairment and quality of life (QoL) for people with epilepsy (PWE). Participants were recruited from epilepsy centers in 4 states and block-randomized into the following groups: in-person HOBSCOTCH (H-IP), virtual HOBSCOTCH (H-V), and waitlist control. Outcome measures were assessed for all groups at baseline, 3 months, and 6 months; intervention groups received long-term follow-up at 9 and 12 months. RESULTS: A total of 108 participants were recruited, of whom 85 were included in this analysis (age at baseline 47.5 ± 11.5 years; 68% female). Participants completing the in-person intervention (H-IP) had a 12.4-point improvement in QoL score compared with controls (p < 0.001). Pairwise comparisons found a 6.2-point treatment effect for subjective cognition in the H-IP group (p < 0.001). There were no meaningful group differences in objective cognition or health care utilization at any time points and the treatment effect for QoL diminished by 6 months. The virtual intervention demonstrated feasibility but did not significantly improve outcomes compared with controls. Within-group analysis found improvements in QoL for both H-V and H-IP. DISCUSSION: This study replicated the effectiveness of the HOBSCOTCH program in improving QoL for PWE. The study was conducted prior to the COVID-19 pandemic, but the distance-delivered intervention may be particularly well-suited for the current environment. Future research will explore modifications designed to improve the efficacy of H-V and the sustainability of HOBSCOTCH's treatment effect. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov (NCT02394509). CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that in-person HOBSCOTCH delivery improved subjective measures of cognition in persons with epilepsy.

Psychiatric provider comfort and perception regarding psychogenic nonepileptic seizures.

The treatment of psychogenic nonepileptic seizures (PNES) involves psychotherapy: yet there is a gap in the understanding of the perceptions and comfort of therapy providers regarding PNES. In this study, we surveyed providers of therapy, including psychiatrists, psychiatric nurse practitioners, physician assistants, psychologists, and social workers, to collect information regarding their comfort and perceptions in caring for individuals with PNES. This study identified differences between physician and non-physician groups in training about PNES and in exposure to patients with PNES. While 26.7% of non-physician providers describe prior training in PNES, 48.3% endorse feeling comfortable treating PNES, suggesting that comfort is based in areas other than prior training. And while providers (83.8% of physicians and 82.1% of non-physicians) deny concern about patients having an in-appointment episode, 36.1% of physicians and 51.7% of non-physicians are concerned that they would not be able to tell apart a nonepileptic versus epileptic episode. While physicians and non-physician providers were similar in their views regarding chronicity, cyclicality, effect of treatment, and illness coherence of PNES, physicians noted significantly greater perceptions of the negative consequences and patient control ability. While both groups viewed PNES as improving with treatment, 83.8% of physicians and 89.7% of non-physicians agreed or strongly agreed that more training in PNES would increase their comfort.

Self-management practices associated with quality of life for adults with epilepsy.

Epilepsy self-management practices enhance a patient's competence and confidence in managing their chronic condition, which is assumed to lead to an improved quality of life (QoL). We analyzed the relationship between the Epilepsy Self-Management Scale (ESMS) responses and the Quality of Life in Epilepsy (QOLIE-31) scores. Baseline questionnaires from HOBSCOTCH, a self-management program for cognitive problems, were administered in four New England epilepsy centers on adults (n = 100) with epilepsy and subjective memory complaints. There was no correlation between overall self-management scores and overall quality-of-life scores; however, subscale analyses indicated that certain self-management practices were strongly correlated with the overall QOLIE-31 score. Specifically, improved ESMS lifestyle management was associated with an increased quality-of-life score (adjusted p < 0.01), while enhanced ESMS safety management practices were associated with a decreased overall quality-of-life score (adjusted p < 0.01). Our item-level analysis highlighted specific items within the ESMS safety management, ESMS lifestyle management, and ESMS information management subdomains that were significant predictors for QoL. Depression was also shown to be significantly correlated with the QOLIE-31 (p < 0.01). Our study suggests that an overemphasis on safety practices may negatively affect quality of life, while enhanced lifestyle management has positive effects. Furthermore, our finding that quality of life is greatly dependent on depressive symptoms underscores the importance of treating depression in epilepsy.

Efficacy of surgical treatment of de novo, adult-onset, cryptogenic, refractory focal status epilepticus.

BACKGROUND: There have been few published reports of successful surgical treatment of focal status epilepticus. Surgical intervention is considered a last resort after medical strategies have been exhausted. OBJECTIVE: To report a case of an adult who was initially seen with de novo, medically refractory, cryptogenic focal status epilepticus and underwent resection of an electrographically defined portion of the left middle frontal gyrus with multiple subpial transections of the adjacent cortex resulting in termination of the electroclinical seizure activity. DESIGN: Report of a case of successful surgical treatment of cryptogenic focal status epilepticus. INTERVENTION: After an initial 35 days of oral antiepileptic drug therapy and subsequent 16 days of continuous electroencephalography-guided intravenous antiepileptic drug therapy in an intensive care unit setting, and after extensive preoperative and intraoperative characterization of the epileptogenic zone, a tailored resection of the left middle frontal gyrus with multiple subpial transections of the surrounding cortex was performed. RESULTS: The restricted surgical resection and multiple subpial transections terminated the seizure activity. Neuropathological examination of the resected tissue revealed moderate inflammatory changes and a few abnormally located neurons without any definitive evidence of dysplasia, which was suspected preoperatively. CONCLUSIONS: We suggest that focal cortical resection may be an appropriate intervention in medically refractory focal status epilepticus even when an overt structural etiology is not evident preoperatively and should be considered as an option at the onset of intractability.

Mechanisms underlying the production of carapace vibrations and associated waterborne sounds in the American lobster, Homarus americanus.

American lobsters produce carapace vibrations, which also lead to waterborne acoustic signals, by simultaneously contracting the antagonistic remotor and promotor muscles located at the base of the second antenna. These vibrations have a mean frequency of 183.1 Hz (range 87-261 Hz), range in duration from 68 to 1720 ms (mean 277.1 ms) and lead to waterborne sounds of similar frequencies. Lobsters most often produce these signals using only one pair of muscles at a time and alternate between the muscles of the left and right antennae when making a series of vibrations. Occasionally, they vibrate their carapace by simultaneously contracting both sets of muscles. While the remotor muscle is required for producing carapace vibrations, the promotor appears to play a secondary role. Electrical stimulation of the remotor, but not the promotor, results in the production of vibrations, while lesions of the remotor, but not promotor, eliminate the ability of lobsters to vibrate their carapace. Lobsters of all sizes and both sexes produce these signals when startled, grasped or threatened. However, at this time, the behavioral significance of vibration and/or sound production by American lobsters is not known.
