“…There have been many attempts at providing guidelines for the optimal diagnostic workup of patients with suspected PNES (Bodde et al, 2009;Cragar et al, 2002;Devinsky et al, 2011;LaFrance et al, 2013;Reuber & Elger, 2003).…”

Suggestive seizure induction is a widely used method for diagnosing psychogenic nonepileptic seizures (PNES). Despite seven decades of multidisciplinary research, however, there is still no unified protocol, no definitive agreement on the ethical framework and no consensus on diagnostic utility. This systematic review surveys the evidence at hand and addresses clinically relevant aspects of suggestive seizure induction. In addition to its use for facilitating the diagnostic process, its mechanism of action and utility in elucidating the psychopathology of PNES will be discussed.

“…The co-existence of epilepsy and PNES in 10% of patients may also complicate making accurate diagnoses. Patients with seizures are misdiagnosed often [13,14,24,27], even with the availability of vEEG technology [50], resulting in treatment delay and possible unnecessary treatment. This delay may promulgate incorrect treatment with AEDs and put the patient with PNES at iatrogenic risk [51].…”

“…PNES, commonly called pseudo seizures, are a relatively uncommon disorder with a prevalence of around 1 to 33 cases per 100, 000 and they account for 5 − 20% of patients thought to have epilepsy [3]. There is potential for severe harm from the adverse side effects or teratogenicity of anti-epileptic drugs (AEDs) prescribed to PNES patients [4], as well as morbidity and mortality from intubation for prolonged seizures [5]. The inaccurate diagnosis may also result in delayed psychological treatment for the issues underlying the attacks, and social stigma associated with epilepsy.…”

Epilepsy is one of the most common neurological disorders and patients suffer from unprovoked seizures. In contrast, psychogenic nonepileptic seizures (PNES) are another class of seizures that are involuntary events not caused by abnormal electrical discharges but are a manifestation of psychological distress. The similarity of these two types of seizures poses diagnostic challenges that often leads in delayed diagnosis of PNES. Further, the diagnosis of PNES involves high-cost hospital admission and monitoring using video-electroencephalogram machines. A wearable device that can monitor the patient in natural setting is a desired solution for diagnosis of convulsive PNES. A wearable device with an accelerometer sensor is proposed as a new solution in the detection and diagnosis of PNES. The seizure detection algorithm and PNES classification algorithm are developed. The developed algorithms are tested on data collected from convulsive epileptic patients. A very high seizure detection rate is achieved with 100% sensitivity and few false alarms. A leave-one-out error of 6.67% is achieved in PNES classification, demonstrating the usefulness of wearable device in the diagnosis of PNES.
