Abstract

A questionnaire was administered to patients in the Montefiore Medical Center outpatient epilepsy department to assess perceptions about stress, seizures, and stress reduction. Eighty-nine patients completed the questionnaire. Overall, 64% of patients reported the belief that stress increased the frequency of their seizures. This belief was not significantly associated with gender, age, location of care, epilepsy classification, or seizure control, but was significantly associated with a shorter duration of epilepsy (P=0.04). Thirty-two percent of subjects had tried stress reduction modalities for epilepsy. Of those who had not, 53% were willing to try, and this willingness was significantly associated with a greater number of seizures in the prior 2 months (P=0.006) and the belief that stress was associated with seizures (P=0.04). Both major and minor stressors were reported with equal frequency. The majority of our study population believe that stress and seizures are related, and are willing to try stress reduction techniques for seizure control. We believe that these findings indicate a need for a prospective study to evaluate the role of stress and stress reduction as an additional potential therapeutic modality for epilepsy.

Introduction

Many patients with epilepsy report that stress exacerbates their seizures, but the association between stress and epilepsy is difficult to study. There are few objective measures of stress, and other factors such as fatigue and sleep deprivation must be considered [1], [2]. Nonetheless, if it can be reliably demonstrated that stress as an isolated factor does increase seizure frequency, then this may lead to a greater use of alternative treatments in epilepsy, including a variety of stress reduction modalities. As a preliminary step to a planned treatment trial of alternative therapies for epilepsy, this study was performed to explore and delineate patients’ perceptions of stress and specific stressors as related to seizure control.

Patient selection

Patients followed in the Epilepsy Management Center of Montefiore Medical Center were considered for inclusion in the questionnaire study if they met the following criteria: duration of epilepsy >1 year; age ⩾18; ability to read and complete an English or Spanish questionnaire. Of 96 eligible participants, 3 declined to participate, and 4 questionnaires were later excluded due to missing data.

Stress and seizures

Patients’ perceptions about the association between seizures and stress were addressed: “Have you ever

Demographic and epilepsy data

Eighty-nine subjects completed the questionnaire. Gender: female 59.5%; male 40.5%. Age: mean 38.2; range 18–25 (21.3%), 26–34 (19.1%), 35–50 (42.7%), and >50 (16.9%). Site of care: seizure clinic (46%), faculty practice (54%). Epilepsy classification: localization-related (87.6%), idiopathic/primary generalized (12.4%). Degree of seizure control: well-controlled (32.6%), not well-controlled (67.4%).

The association between stress and seizures

Overall, 57 of 89 (64%) subjects believed that some of their seizures were related to stress.

Discussion

Most studies of seizure precipitants identify stress as a frequent self-reported precipitant. Both stress levels [7] and major life events [8] have been reported in association with increased seizure frequency. Unfortunately, stress often coexists with other potential seizure precipitants, and the evaluation of stress as an independent factor is difficult, as was demonstrated by a questionnaire study of seizure precipitants by Mattson in 1991 [2]. Of 177 patients who completed a detailed survey
