Behavioral health in young adults with epilepsy: Implications for transition of care.

Aim: Neurodevelopmental and behavioral health disorders commonly occur with epilepsy, yet risk for young adults is unknown. The aim of this study was to determine the distribution and risk characteristics of neurodevelopmental and behavior health comorbidities among young adults with epilepsy compared with those among young adults with migraine and healthy controls.

Method: A case-control study examining hospital admission, outpatient, and emergency department (ED) visits for young adults with an ICD-9-CM diagnosis of epilepsy, migraine, or lower extremity fracture (LEF) was conducted.

Mortality following status epilepticus in persons with and without epilepsy.

Purpose: Incidence of status epilepticus (SE) ranges from 6.8 to 41.0 per 100,000 population.

Mortality in people with epilepsy: A statewide retrospective cohort study.

Rationale: People with epilepsy (PWE) have a higher risk of mortality than the general population, because of disparities in the receipt of appropriate epilepsy care, which may be affected by socioeconomic status, race/ethnicity and insurance coverage. Increased epilepsy prevalence has been associated with black race, low educational attainment, unemployment, and low income levels. Rural/urban residence may affect health through individual or environmental factors.

Population-based comparative analysis of risk of death in children and adolescents with epilepsy and migraine.

Objective: Follow-up studies of children and adolescents with epilepsy (CAW-E) have revealed higher risk of mortality than children in the general population. The mortality experience of CAW-E relative to patients with other common neurologic disorders in the pediatric age group is yet undetermined. The objectives of this study are the following: (1) to compare the causes and the adjusted risk of death in CAW-E with that of children and adolescents with migraine (CAW-M) in reference to children and adolescents with lower extremity fracture (CAW-LEF), and children and adolescents in the general population; (2) to evaluate if disparate mortality risks exist by demographic characteristics.

Determining patient needs: A partnership with South Carolina Advocates for Epilepsy (SAFE).

Purpose: The purpose of this study was to collaborate with a community partner to administer a current needs assessment of persons with epilepsy (PWE) and determine the types of resources that PWE would like to access through the community partner.

Methods: A self-report needs assessment survey was administered to caregivers and PWE across the state of South Carolina during a community partner educational workshop (n=20) and via secure software distributed through an email link (n=54).

Key Findings: The most frequently reported challenges (>50%) were concerns about finding time to participate in epilepsy community activities, the personal safety of the PWE, finding social connections or social support, finding mental or behavioral health services, and work concerns.

Stroke after adult-onset epilepsy: a population-based retrospective cohort study.

Background: Earlier studies indicate a higher risk of subsequent stroke in PWE aged ≥60. However, little is known of the incidence of subsequent stroke in people with epilepsy (PWE) aged 35 through 60. We determined the risk factors that increase the incidence of stroke following adult-onset epilepsy in a large statewide population over a 10-year period.

Premature deaths among children with epilepsy - South Carolina, 2000-2011.

Epilepsy is a common childhood neurologic disorder. In 2007, epilepsy affected an estimated 450,000 children aged 0-17 years in the United States. Approximately 53% of children with epilepsy and special health care needs have co-occurring conditions, and only about one third have access to comprehensive care.

Epilepsy beyond seizure: a population-based study of comorbidities.

Comorbid conditions may affect the quality of life in persons with epilepsy (PWE) more than seizures. Using legally mandated healthcare encounter data, somatic, psychiatric, and neurodevelopmental comorbidities in a large population-based cohort of PWE, were compared to persons with migraine (PWM), a similar neurologic condition, and lower extremity fracture (PWLF), otherwise healthy controls. 64,188 PWE, 121,990 PWM, and 89,808 PWLF were identified from inpatient, outpatient, and emergency department from 2000 to 2011.

A population-based study of risk of epilepsy after hospitalization for traumatic brain injury.

Purpose: This study was undertaken to determine the risk of developing posttraumatic epilepsy (PTE) within 3 years after discharge among a population-based sample of older adolescents and adults hospitalized with traumatic brain injury (TBI) in South Carolina. It also identifies characteristics related to development of PTE within this population.

Methods: A stratified random sample of persons aged 15 and older with TBI was selected from the South Carolina nonfederal hospital discharge dataset for four consecutive years.

Psychosocial factors associated with stigma in adults with epilepsy.

Living Well with Epilepsy II called for further attention to stigma and its impact on people with epilepsy. In response, the South Carolina Health Outcomes Project on Epilepsy (SC HOPE) is examining the relationship between socioeconomic status, epilepsy severity, health care utilization, and quality of life in persons diagnosed with epilepsy. The current analysis quantifies perceived stigma reported by adults with epilepsy in relation to demographic, seizure-related, health, and psychosocial factors.

Caregiver perceptions of seizure severity in pediatric epilepsy.

Purpose: Seizure severity has been investigated using multiple tools over the years, and its defining features continue to be debated. Severity ratings are necessary for medical, psychological, and epidemiologic investigations. Adults with epilepsy have been evaluated more than youth with epilepsy.

Prevalence of self-reported epilepsy, health care access, and health behaviors among adults in South Carolina.

Behavioral Risk Factor Surveillance System data from South Carolina for 2003-2005 were used to determine epilepsy prevalence and prevalence variation by demographic subgroups, and to compare health insurance coverage, health care visits, and health-related behaviors among persons with epilepsy and the general population. Two percent of respondents reported they had ever been told by a doctor that they had epilepsy, and 1% reported active epilepsy. Almost half of those with active epilepsy reported a seizure in the prior 3 months.

Complete heart block with ventricular asystole during left vagus nerve stimulation for epilepsy.

Vagus nerve stimulation (VNS) is an important therapeutic option for individuals with refractory epilepsy who have failed multiple antiepileptic drugs (AEDs). The intricate relationship of the vagus nerve to cardiac function raises concern that vagal stimulation may affect cardiac rhythm and function. Previous pre- and postmarketing studies have not shown this to be a significant problem, with the incidence of bradyarrhythmias reported to be about 0.

Incidence of spikes and paroxysmal rhythmic events in overnight ambulatory computer-assisted EEGs of normal subjects: a multicenter study.

The incidences of spikes and paroxysmal rhythmic events (PREs) in 10-h overnight EEGs of normal adult volunteers (n=135) were studied at 11 sites with a computer-assisted ambulatory EEG monitoring system with automatic spike and PRE detection. Spikes were evident in the overnight EEG of 1 subject (0.7%), and PREs were apparent in the overnight EEG of the same subject (0.

Sudden unexplained death in epilepsy: observations from a large clinical development program.

Purpose: The present study was conducted to determine the rate of sudden unexplained death in epilepsy (SUDEP) in a well-defined cohort of patients included in the lamotrigine (LTG) clinical development database.

Methods: A panel of scientists experienced in the area of SUDEP was assembled and provided with case summaries on all deaths (n = 45) reported during the initial clinical development of LTG. The panel developed a set of criteria for classifying cases as SUDEP (definite or highly probable), possible SUDEP, or non-SUDEP.

Current strategies in the medical management of epilepsy.

Epilepsy is a fascinating disorder reflective of ongoing brain activity which at times is disordered. There have been significant advances in the understanding of the pharmacology of antiepileptic drugs such that effective treatment is feasible. Understanding the epilepsies and the phenomena of epileptic seizures will permit one to successfully deal with the major issues around these syndromes and lead to a very rewarding outcome.

Immunochromatographic measurement of phenobarbital in whole blood with a non-instrumented assay.

We tested the precision and accuracy of the AccuLevel Phenobarbital Test, which reports whole-blood (fingerstick) results in plasma equivalent values, and compared these values with plasma results obtained using established methods. We conclude that the assay is precise, reliable, accurate for single tests, and is appropriate for use in offices, outpatient settings, and emergency rooms.

Serum prolactin and cortisol levels in evaluation of pseudoepileptic seizures.

In 6 patients with epilepsy, a twofold increase in serum prolactin levels followed true epileptic seizures, but no significant change followed pseudoepileptic attacks in 6 other patients. Serum prolactin concentration is a useful biochemical marker to distinguish between epileptic and pseudoepileptic seizures. Serum cortisol levels also increased after epileptic seizures, but diurnal and individual variations render the cortisol level a less reliable indicator of such attacks.

Autonomic nervous system and epilepsy.

Seizures frequently manifest autonomic dysfunction clinically, and seizure discharges commonly spread into and involve autonomic pathways. These associations are direct and simple in some instances, and the result of multiple indirect and complex relationships in others. Effects of epileptic discharge on the autonomic nervous system are mediated through the cortical, limbic, and hypothalamic systems.

Endocrine function following complex partial seizures.

Previous studies have demonstrated hyperprolactinemia following generalized tonic-clonic seizures and after electroconvulsive therapy. We found transient hyperprolactinemia following complex partial seizures but little change in serum gonadotropins, thyroid-stimulating hormone, growth hormone, or cortisol. Serum prolactin was invariably normal interictally.

Kinetics of a carbamazepine-ethosuximide interaction.

Carbamazepine and ethosuximide are used together to treat epileptic mixed-seizure patterns. Since carbamazepine has been shown to induce drug-metabolizing enzyme(s) in the liver, it follows that carbamazepine may alter ethosuximide disposition. Six normal subjects took one 250-mg ethosuximide capsule twice each day for 55 consecutive doses (study days 1 to 28) and one 200-mg carbamazepine tablet each evening from study days 11 to 27.
