Objective:
Epilepsy, and specifically drug-resistant epilepsy (DRE), is associated with an increased risk of psychiatric dysfunction, likely due to a combination of physiological mechanisms, emotional reactions to disease burden, and bi-directional influences. Women with epilepsy warrant special consideration due to many factors, including hormonal influences on seizure susceptibility, reproductive health considerations, and unique psychiatric and clinical profiles. However, there is yet to be large-scale research characterizing women with DRE. The present study characterized psychiatric conditions, treatment, and hospitalization data in a Veterans Health Administration (VHA)-wide sample of women Veterans and then compared results to a male Veteran sample to explore sex differences.
Participants and Methods:Data from 52,579 Veterans enrolled in VHA care between FY2014 and 2nd Quarter FY2020 were gathered from the VHA Corporate Data Warehouse administrative data. The sample was comprised of 5,983 women (11.4%) and 46,596 men (88.6%). Demographics, psychiatric diagnoses, psychiatric medications, ER visits, and hospitalizations were characterized. Chi-square analyses were used to examine group differences between men and women.
Results:The vast majority of the women Veteran sample had at least one psychiatric diagnosis (86.1%), with over half of the sample diagnosed with depression (68.3%), PTSD (54.1%), and/or anxiety disorders (57.7%). When compared to men, women Veterans were more likely to have a psychiatric diagnosis (86.1% vs. 68.1%), evidenced a higher number of co-morbid psychiatric conditions (2.4 vs. 1.6), and were prescribed more psychiatric medications (3.4 vs. 2.3; all significant at p<0.001). All individual psychiatric diagnoses were more prevalent in women than men and, notably, suicidality was also higher in women (13.5% vs. 10.0%; p < 0.001). Women Veterans also had a higher number of ER visits (6.9 vs. 5.5; p < 0.001) and psychiatric hospitalizations than men (.4 vs. .3, p < 0.001).
Conclusions:The present study represents the largest known investigation to date of women with DRE and is also the largest study of women Veterans with any form of epilepsy. It highlights a vast psychiatric burden in this subset of women Veterans, with high rates of psychiatric comorbidity, lending to downstream effects on psychiatric medication burden and risk for emergency care usage and psychiatric hospitalization. Comparisons to men emphasize that women are differentially impacted by the psychiatric toll of DRE and warrant special consideration. The markedly higher rates of depressive disorders and suicidality in women Veterans with DRE is especially notable when considering risk of harm and mortality. Overall, the present work adds to the paucity of literature of women Veterans with seizures and gaps in the broader DRE research base, with implications for specialized screening and maximizing treatment interventions in this population.

Objective:
Poor mood and quality of life is common among patients with medically intractable seizures. Many of these patients are not candidates for seizure focus resection and continue to receive standard medical care. Responsive neurostimulation (RNS) has been an effective approach to reduce seizure frequency for nonsurgical candidates. Previous research using RNS clinical trial participants has demonstrated improved mood and quality of life when patients received RNS-implantation earlier in their medically resistant epilepsy work-up (Loring et al., 2021). We aimed to describe the level of depression and quality of life in adults with medical resistant epilepsy, treated with RNS, presenting to an outpatient clinic.
Participants and Methods:This pilot study was conducted among 11 adult epilepsy patients treated with RNS at the epilepsy specialty clinic at Baylor College of Medicine. Ages of participants ranged from 18-56 (M=32.01, SD=12.37) with a mean education of 12.43 (SD=0.85). The majority of the participants identified as White (White=72.2%; Hispanic/Latino/a=14.3%, Other=7.1%). We also present pre- and post-RNS preliminary results of a subset of 4 patients for whom pre and post implantation data was available. Depression symptoms were assessed through the Beck Depression Inventory, 2nd Edition (BDI-II) and quality of life was determined using the Quality of Life in Epilepsy (QoLiE-31).
Results:Patients reported minimal symptoms of depression (M=5.45, SD=4.03) and good overall quality of life (M=71.18, SD=14.83) after RNS. Participants’ scores on their overall quality of life ranged from 50 to 95 (100=better quality of life). The QoLiE-31 showed high scores on emotional wellbeing (M=69.45, SD=14.56) and cognitive functioning (M=65.36, SD=16.66) domains. Post-hoc analysis revealed a significant difference in the cognitive functioning domain of QoLiE-31 before (M=44.75, SD=12.58) and after (M=51.0, SD=11.58) RNS implantation(t(3)=-3.78, p=0.016. Additionally, overall QoLiE score approached statistical significance when comparing pre-RNS (M=44.75 SD=9.29) to post-RNS (M=49.75 SD=11.62; t(3)=-2.01, p = 0.069). No significant differences were evident on seizure worry, energy/fatigue, medication effects, and social functioning domains of QoLiE-31 before and after RNS treatment.
Conclusions:These pilot study results suggest low levels of depression with this population post-RNS implantation. Additionally, there is preliminary evidence to suggest improved patient-rated cognitive functioning and overall quality of life. While this is a small study population, the results have important implications for patients with intractable epilepsy, even with those form who surgical resection may not be possible. Future studies with large enough samples to examine moderating and mediating factors to mood and quality of life changes post-RNS will be important.
