Results: Patients with epilepsy and PNES were found to have similar HRQOL in physical, psychological, social, and environmental domains. However, the percentage of comorbid psychiatric disorders were higher in patients with PNES than patients with epilepsy.

Conclusion: Patients with epilepsy and PNES have similar HRQOL, and PNES are resistant to the standard medical therapies used for the treatment of epileptic seizures. The direct lifetime cost of undiagnosed PNES may be of equal with intractable epilepsy. A better understanding of the impact of PNES manifestations and epilepsy would help to provide appropriate clinical, psychological and social care.

HRQOL in patients with epilepsy and PNES … Yerdelen & Altintas

E

pilepsy is a chronic brain disease characterized by recurrent seizures and is associated with profound physical, psychological, and social consequences. Psychogenic non-epileptic seizures (PNES) can be defined as paroxysmal involuntary behaviors without an organic cause and mimic epileptic events. The incidence of PNES is 4.9/100.000/year and it is estimated that approximately 20-30% of patients referred to tertiary care epilepsy centers for refractory seizures have both epilepsy and PNES, and approximately 17-30% had PNES.1 Psychogenic non-epileptic seizures frequently coexists with psychiatric diseases such as anxiety, depression, posttraumatic stress disorder, suicidal attempts, or other psychological disorders.2 Psychiatric comorbidities are present in a significant number of people with epilepsy.3 Patients with PNES have poorer health-related quality of life (HRQOL) than patients with epilepsy.4,5 The HRQOL questionnaire includes 4 domains: physical health, psychological health, social relations, and environment.6 In this study, we aimed to evaluate the HRQOL of patients admitted to the video-electroencephalography (EEG) monitoring unit diagnosed with epilepsy or PNES, and to find out any differences between epilepsy and PNES regarding HRQOL as suggested in previous studies.4,5 We also aimed to evaluate the comorbid psychiatric disorders in both groups and compare with previous studies. The question of necessity of considering PNES as important as epilepsy has been discussed. Methods. This cross-sectional study included 125 adult patients admitted for video/EEG monitoring and diagnosed with epilepsy (n=64) or PNES (n=54). This study was carried out in the Department of Neurology and Psychiatry, Faculty of Medicine, Baskent University, Adana, Turkey, between December 2010 and December 2014. The study protocol followed the ethical guidelines of the most recent Declaration of Helsinki and was approved by the Baskent University Institutional Review Board and Ethics Committee of the Baskent University, Adana, Turkey. Written consent was obtained from all the patients. Parents were asked to signed the consent form for patients under the age of 18 years. Exclusion criteria included schizophrenia, schizophreniform disorder, bipolar affective disorder, mental retardation, other neurological disorders, age

Quality of life in psychogenic nonepileptic seizures and epilepsy: the role of somatization and alexithymia.
It is clear that many individuals with psychogenic nonepileptic seizures (PNESs) often present with poorer quality of life compared with those with epileptic seizures (ESs). However, the mechanisms linking seizure diagnosis to quality-of-life outcome

The primary aim of this study was to explore a possible association between the coping styles and the health-related quality of life (HRQOL) of patients with psychogenic nonepileptic seizures (PNES) in the South African context.

Sleep in psychogenic nonepileptic seizures and related disorders.
Psychogenic nonepileptic seizures (PNES), a form of functional neurological symptom disorder (FNSD), are very rarely seen in genuine, electroencephalography (EEG)-confirmed sleep. However, they are more commonly reported as a nocturnal occurrence, li

Epidemiology of psychogenic nonepileptic seizures.
We critically review the existing literature about the epidemiology (i.e., diagnosis, occurrence, age, gender, comorbidity with epilepsy, associated factors, prognosis, mortality, and cost) of psychogenic nonepileptic seizures (PNES) and provide sugg

Regulation of emotions in psychogenic nonepileptic seizures.
Despite the long history of psychogenic nonepileptic seizures (PNES), relatively little is known about the mechanisms that cause and maintain this condition. Emerging research evidence suggests that patients with PNES might have difficulties in regul
