PURPOSE: To investigate ability to recognize paroxysmal neurological events (PNE) based on video-recorded events alone in a group of physicians treating prevalent neurological conditions. METHODS: Total of 12 patients' videos (6 epileptic seizures (ES), 4 psychogenic nonepileptic seizures (PNES), 2 other nonepileptic seizures (oNES)) were selected. Videos were displayed once to physicians blind to clinical data and final diagnosis. Physicians determined their clinical choice: ES, PNES, oNES, and I don't know (IDK)...

INTRODUCTION: Idiopathic generalised epilepsies (IGE) are a set of electroclinical syndromes with different phenotypes. Our aim is to analyse those phenotypes in patients over 16 years of age. PATIENTS AND METHODS: We conducted a retrospective analysis of a series of patients with IGE. They were classified as childhood absence epilepsy (CAE), juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), epilepsy with tonic-clonic seizures only (TCSE), epilepsy with eyelid myoclonias and absences (EMA) and pure photogenic epilepsy (PE)...

BACKGROUND: This study aimed to extend the current understanding of dissociative symptoms experienced by patients with dissociative (psychogenic, non-epileptic) seizures (DS), including psychological and somatoform types of symptomatology. An additional aim was to assess possible relationships between dissociation, traumatic experiences, post-traumatic symptoms and seizure manifestations in this group. METHOD: A total of 40 patients with DS were compared with a healthy control group (n = 43), matched on relevant demographic characteristics...

Perri Carlson, Kathryn Nicholson Perry
PURPOSE: The aim of this meta-analysis is to evaluate and synthesize the available evidence from the previous 20 years regarding the utility of psychological interventions in the management of psychogenic non-epileptic seizures (PNES). METHOD: Studies were retrieved from MEDLINE via OvidSP and PsychINFO. Selection criteria included controlled and before-after non-controlled studies including case series, using seizure frequency as an outcome measurement. Studies were required to assess one or more types of psychological intervention for the treatment of PNES in adults...

Pruritus can be one of the distressing symptoms of many dermatologic, systemic, neurologic or psychiatric disorders. In each case, the origin of itch is in the skin and/or the nervous system. Involvement of the nervous system causes neurogenic, psychogenic or neuropathic itch. Itch sensation is transferred to the central nervous system via unmyelinated C-type nerve fibers, and many mediators and receptors engage in the its induction and transmission. Also it has been demonstrated that there are similarities and interactions between neurotransmitters and pathways of pain and itch sensation...

We sought to investigate (1) differences in ictal duration between psychogenic nonepileptic seizures (PNES) and epileptic seizures (ES), (2) the odds of being PNES when seizures last ≥5min, and (3) the value of ictal duration as a diagnostic test to differentiate PNES from ES. We retrospectively reviewed video-EEG recordings and tabulated ictal durations of all PNES and ES. We estimated the mean ictal durations of PNES and ES using linear mixed models. The odds of being PNES when seizures last ≥5min were estimated using logistic regression...

OBJECTIVES: Psychopathology levels are elevated in patients with psychogenic non-epileptic seizures (PNES) and those with epilepsy. However, patients with PNES report higher rates of trauma and neglect, poorer health-related quality of life (HRQoL), and an increased prevalence of insecure attachment. We examined to what extent attachment style and relationship quality with their main informal carer impact on levels of HRQoL, depression, and anxiety in patients with PNES versus those with epilepsy...

Exposure to chronic stress before and well after the induction of endometriosis is reported to increase lesion sizes in rats, but it is unclear whether stress, exposed shortly after the induction of endometriosis, would also promote the development of endometriosis, nor is it clear what the underlying possible molecular mechanism is. This study was undertaken to test the hypothesis that chronic stress can promote the development of endometriosis. A prospective randomized mouse experiment was conducted that subjected mice with induced endometriosis to predator stress...

OBJECTIVE: Although there is general consensus that psychogenic non-epileptic seizures (PNES) are treated with psychotherapy, the effectiveness of most psychotherapeutic modalities remains understudied. In this treatment series of 16 patients dually diagnosed with PNES and post-traumatic stress disorder (PTSD), we evaluated the effect of prolonged exposure therapy (PE) on reduction of PNES. Secondary measures included Beck Depression Inventory (BDI-II) and Post-Traumatic Disorder Diagnostic Scale (PDS)...

This study was undertaken to identify the cause of impotence in men undergoing radical prostatectomy, with the hope that this information may provide insight into the possible prevention of this complication. The autonomic innervation of the corpora cavernosa in the male fetus and newborn was traced to determine the topographical relationship between the pelvic nerve plexus, and the prostate, urethra and urogenital diaphragm. We have demonstrated that the branches of the pelvic plexus that innervate the corpora cavernosa are situated between the rectum and urethra, and penetrate the urogenital diaphragm near or in the muscular wall of the urethra...

BACKGROUND: Seizures result in a change in motor, sensory, and behavioral symptoms caused by abnormal neurologic electrical activity. The symptoms share similar presentations of several other conditions, leading to difficulties in diagnosis and frequent improper management. OBJECTIVE: This review evaluates adult patients with suspected seizure, signs and symptoms of seizure, mimics of seizure, and an approach to management of seizure mimics. DISCUSSION: A seizure is caused by abnormal neurologic electrical activity resulting in altered motor, sensory, and behavioral symptoms...

PURPOSE OF REVIEW: Functional dizziness is the new term for somatoform or psychogenic dizziness. The aim of this study is to review arguments for the new nomenclature, clinical features, possible pathomechanisms, and comorbidities of functional dizziness. RECENT FINDINGS: The prevalence of functional dizziness as a primary cause of vestibular symptoms amounts to 10% in neuro-otology centers. Rates of psychiatric comorbidity in patients with structural vestibular syndromes are much higher with nearly 50% and with highest rates in patients with vestibular migraine, vestibular paroxysmia, and Ménière's disease...

Tremors are commonly encountered in clinical practice and are the most common movement disorders seen. It is defined as a rhythmic, involuntary oscillatory movement of a body part around one or more joints. In the majority of the population, tremor tends to be mild. They have varying etiology; hence, classifying them appropriately helps in identifying the underlying cause. Clinically, tremor is classified as occurring at rest or action. They can also be classified based on their frequency, amplitude, and body part involved...

BACKGROUND: The long-term safety of deep brain stimulation (DBS) is an important issue because new applications are being investigated for a variety of disorders. Studying instances where DBS was inadvertently implanted in patients without a movement disorder may provide information about the safety of the therapy. We report the case of a patient with a psychogenic movement disorder treated with deep brain stimulation (DBS). CASE DESCRIPTION: The patient presented at our clinic after 5 years of chronic DBS of the subthalamic nucleus (STN) for presumed Parkinson's disease...

REVIEW
Lawrence Zemel, Peter R Blier
Juvenile fibromyalgia (JFM), a chronic disorder of widespread musculoskeletal pain in combination with autonomic, sensory, and cognitive dysfunction, is responsible for considerable morbidity and impaired quality of life in affected patients and their families. Historically, fibromyalgia has been incorrectly characterized as a psychosomatic or psychogenic disorder, but new understanding of the science of pain has demonstrated unambiguously that it is an organic disorder of the pain processing system itself...

Psychogenic Nonepileptic Seizures (PNES) are one of the commonest differential diagnoses of epilepsy. This paper provides a narrative review of what has been learnt in the last 25 years regarding the visible manifestations, physiological features, subjective experiences and interactional aspects of PNES. We then explore how current insights into PNES semiology and phenomenology map onto the Integrative Cognitive Model (ICM), a new account of these phenomena that unifies previous approaches within a single explanatory framework...

BACKGROUND AND OBJECTIVE: Although many patients present with functional neurological symptoms (FNS), few US clinics offer specialized FNS care, and data on clinic attendees remain limited. We determined predictors of initial attendance, symptom burden, and FNS subtype in the first patients referred to our Functional Neurological Disorders Clinic for suspected FNS. METHODS: We reviewed the charts of 62 consecutive patients (46 women, 16 men). Regression analyses investigated predictors of keeping the first scheduled clinic appointment...

Paul Secombe, Chris Milne
Hyponatraemia-induced rhabdomyolysis is a rare, but reported phenomenon, particularly in patients with chronic schizophrenia on depot antipsychotics prone to psychogenic polydipsia. To the best of our knowledge, there are no reported cases of hyponatraemia-induced rhabdomyolysis complicated by oligo-anuric acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT). The initiation of CRRT is complicated in severe hyponatraemia, predominantly due to the need to avoid rapid changes in tonicity associated with rapid changes in sodium...
