Background:
A history of adverse life events (ALE) is a risk factor for functional seizures (FS). Their influence on long-term outcome remains unclear. International guidelines recommend assessing ALE in patients presenting with associated disorders. It is not clear to what extent patients evaluated for FS are regularly asked about ALE.
Objectives:
We hypothesised that the presence of ALE would relate to worse outcome at follow-up and, that the rate of detection of ALE in clinical work-up would be inferior to that based on self-report questionnaires.
Methods:
53 patients with FS from the National Centre for Epilepsy in Norway, aged 16-62 years were included. Symptom severity, health-related quality of life (HRQoL), and antecedent ALE were assessed at baseline. Medical records were examined for disclosure of ALE. At a mean of 70.45 (SD 29.0, range 22-130) months after inclusion, participants were inquired about FS status, FS-related health care utilization and HRQoL.
Findings:
A history of emotional abuse documented in the medical record was an independent risk factor for worse HRQoL at follow-up. Prevalence of ALE documented in medical records was lower compared with rates measured by a self-report questionnaire.
Conclusions:
These findings indicate an association between antecedent ALE and HRQoL years after diagnosis. A substantial proportion of the adverse life events by a self-report questionnaire had not been documented in the clinical records.
Clinical Implications:
The supplemental use of a self-report questionnaire in the diagnostic work-up of patients with FS may be valuable for detecting ALE.
