Psychogenic nonepileptic seizures (PNES) superficially resemble epileptic seizures but are not associated with epileptic discharges in the brain. Instead, these episodes, which tend to occur with alterations in consciousness and body movements, are thought to be the result of mechanisms of conversion and dissociation. Psychological trauma and PTSD are very prevalent among patients with PNES. PNES can be conceived of as an extreme avoidance mechanism that serves the function of modulating distress and, in some cases, eliminating the precipitant stressor. Avoidance is also an essential component of PTSD. In patients who carry a dual diagnosis of PNES and PTSD, it is sensible that an empirically validated treatment for PTSD such as prolonged exposure (PE) therapy which targets avoidance by promoting exposure might be a useful approach to treat these patients. In this report, we present the case of a 52-year-old male with a 7-year history of PNES. His seizures, which were characterized by intense body shaking and loud guttural outbursts, were occurring up to 15 times per day. Because of these symptoms, he lost his employment and was ostracized by his family. Upon completion of a course of intensive outpatient PE, he achieved full remission of all psychogenic symptoms. Except for three brief seizures, he has maintained his health for 2 years. This constitutes the first detailed report of PE therapy used to effectively treat comorbid PNES and posttraumatic stress symptoms.

This chapter details how a psychologist opened up therapy groups to accommodate patients with psychogenic non-epileptic seizures (PNES). In those groups, the psychologist had the chance to hear multiple stories and, quite by accident, informally conducted what might be considered qualitative research. The one thing that began to stand out pretty consistently was the presence of psychological trauma. Often while discussing the trauma, patients would experience a seizure. As such, a trauma-based treatment modality that has been around for decades and that has been specifically designed to treat posttraumatic stress disorder (PTSD) might be useful to treat patients who carry a dual diagnosis of PNES and PTSD. The chapter then argues that perhaps the dismissive attitudes of many health professionals toward these patients stem from ignorance and that if they really understood the profound suffering these patients have been through and now continue to experience, they might change their views and behaviors.

Abstract The article presents the case of a 61-year old female patient, with no history of neurological illness, who presents a rapid onset of two convulsive seizures, triggered by a psychological trauma. The first convulsive seizure is repeated within 24 hours. The general, as well as the neurological clinical examination have not found any pathological signs. MRI scanning of the brain pointed to right-parietal schizencephaly, associated with polymicrogyria, the believed causes of the epileptic seizures.

Psychogenic non-epileptic seizures (PNES), are events that resemble epileptic seizures but lack electrophysiological or clinical evidence for epilepsy. Instead, they are psychogenic in origin. These episodes tend to occur with alterations in consciousness and bodily functions and are the result of mechanisms of conversion. Psychological trauma and post-traumatic stress disorder (PTSD) are prevalent among patients with PNES. This is a case report of a 32-year-old male who began treatment 1-year after developing PTSD followed some months later by PNES. His seizures were characterized by contorted movements of the head and neck, guttural sounds, and left sided movements or whole-body arching and were accompanied by frequent falls and injuries. They were usually brief but occurred daily. Psychotherapy had been discontinued because violent seizures often interrupted the sessions. He was treated with prolonged exposure (PE) at a PNES program and by the last session, had achieved an improvement in his seizure frequency (one every 4–6 days rather than daily episodes). This allowed him to begin therapy with a local therapist. Two years after completing treatment, the patient returned for a follow up visit. At that point, his seizure frequency, was one per month which shows he sustained and improved on this symptom. Former head drops, and grunting sounds disappeared, and he was no longer using a cane to ambulate. From an emotional standpoint (PTSD, suicidality, anxiety, quality of life), the patient had achieved and maintained a much healthier level of functioning (though no change on alexithymia, anger, depression, and trait anxiety).

AbstractEpilepsy is a risk factor for the development of psychogenic non-epileptic seizures (PNES) and comorbid epilepsy is recognized as a comorbidity in about 10–30% of patients with PNES. The combination of epileptic and nonepileptic seizures poses a particular diagnostic challenge. In patients with epilepsy, additional PNES may be suspected on the basis of their typical semiology. The possibility of additional PNES should also be considered if seizures fail to respond to antiepileptic drug treatment, in patients with frequent emergency admissions with seizures and in those who develop new types of seizures. The description of semiological details by patients and witnesses can suggest additional PNES. Home video recordings can support an initial diagnosis, however, especially in patients with mixed seizure disorders it is advisable to seek further diagnostic confirmation by capturing all habitual seizure types with video-EEG. The clinical features of PNES associated with epilepsy are similar to those in isolated PNES disorders and include longer duration, fluctuating course, asynchronous movements, pelvic thrusting, side-to-side head or body movement, persistently closed eyes and mouth, ictal crying, recall of ictal experiences and absence of postictal confusion. PNES can also present as syncope-like episodes with unresponsiveness and reduced muscle tone. There is no unique epileptological or brain pathology profile putting patients with epilepsy at risk of additional PNES. However, patients with epilepsy and PNES typically have lower educational achievements and higher levels of psychiatric comorbidities than patients with epilepsy alone. Psychological trauma, including sexual abuse, appears to be a less relevant aetiological factor in patients with mixed seizure disorders than those with isolated PNES, and the gender imbalance (i.e. the greater prevalence in women) is less marked in patients with PNES and additional epilepsy than those with PNES alone. PNES sometimes develop after epilepsy surgery. A diagnosis of ‘known epilepsy’ should never be accepted without (at least brief) critical review. This narrative review summarises clinical, electrophysiological and historical features that can help identify patients with epilepsy and additional PNES.

Over 20 years ago, Watt and Hameroff (1987 ) suggested that consciousness may be described as a manifestation of deterministic chaos in the brain/mind. To analyze EEG-signal complexity, we used Higuchi’s fractal dimension in time domain and symbolic analysis methods. Our results of analysis of EEG-signals under anesthesia, during physiological sleep, and during epileptic seizures lead to a conclusion similar to that of Watt and Hameroff: Brain activity, measured by complexity of the EEG-signal, diminishes (becomes less chaotic) when consciousness is being “switched off”. So, consciousness may be described as a manifestation of deterministic chaos in the brain/mind.
