OBJECTIVE: The number and proportion of women served by the Veterans Health Administration (VHA) is rapidly expanding, necessitating better characterization of factors unique to this population. While nascent literature has begun to better characterize women within the broader seizure population, women Veterans remain an understudied sample. To expand our clinical understanding of women with seizures, we assessed demographic and clinical characteristics, as well as psychiatric/military histories in women receiving care from an Epilepsy Center of Excellence within the VA Healthcare System.
METHODS: The sample included 90 women with psychogenic nonepileptic seizures (PNES) and 28 women with epileptic seizures (ES) as the final diagnosis after epilepsy monitoring at a large VA medical center between 2010 and 2020. Retrospective chart review gathered demographics, including age, marital status, and work status; clinical characteristics, including history of traumatic brain injury (TBI) or migraines, gynecological history, and use of anti-seizure medications (ASM); psychiatric information, including trauma history, psychiatric diagnoses, and treatment; and military history related to service or service connection. Group differences were assessed between women with PNES and ES.
RESULTS: The ES group was significantly older than the PNES group (47.8 v. 41.9 years, p = 0.02) and had a non-significantly longer diagnosis duration (12.3 vs. 8.6 years, p = 0.17). Clinically, the PNES group had a significantly higher rate of migraines (76.7% v. 57.1%, p = 0.04) and hysterectomy (40% v. 17.9%, p = 0.03). Many psychiatric factors differentiated the two groups, with significantly higher rates of psychotropic medication use (86.7% v. 60.7%, p = 0.002), psychiatric hospitalization (42.2% v. 21.4%, p = 0.047), and suicide attempts (42.2% v. 14.3%, p = 0.005), alongside trends toward higher rates of military sexual trauma (47.8% vs. 28.6%, p = 0.07) and childhood sexual trauma (37.8% vs. 17.9%, p = 0.05) among those with PNES.
SIGNIFICANCE: This is the largest study to date characterizing women veterans with seizures seeking comprehensive seizure care and provides an update to previously published information on Veteran samples with seizures. Several characteristics differ between women Veterans with PNES and ES, spanning demographic, clinical, and psychiatric factors. Understanding the unique profile of women Veterans with epilepsy seeking care through the VA system is a crucial step in providing optimal care, including making informed diagnosis and providing appropriate treatment.
