OBJECTIVE: Specialized epilepsy clinics receive many cases (20%-30% of total cases) in which the patients are diagnosed with psychogenic non-epileptic seizures (PNES). In Puerto Rico, there has been a lack of research on and data about patients with PNES. This study examined the clinical profile of 34 patients with a confirmed diagnosis of PNES. METHODS: A secondary analysis of 34 clinical records of patients with PNES was conducted. The resulting profile was based on clinical interviews, the behavioral presentation of seizures, the history of traumatic experiences or abuse, and the relationship between PNES events and life stressors...

Functional neurological disorders (FND)-also called psychogenic, nonorganic, conversion, and dissociative disorders-constitute one of the commonest problems in neurological practice. An occupational therapist (OT) is commonly involved in management, but there is no specific literature or guidance for these professionals. Classification now emphasizes the importance of positive diagnosis of FND based on physical signs, more than psychological features. Studies of mechanism have produced new clinical and neurobiological ways of thinking about these disorders...

BACKGROUND: The fixed dystonia phenotype was originally established as a prototype of functional dystonia. Nevertheless, in recent reports different functional dystonia phenotypes have been recognized with dystonic movement comprising phasic instead of tonic contraction. OBJECTIVES: To examine clinical characteristic in all patients with dystonia who fulfilled the criteria for functional movement disorders irrespective of phenotype in an attempt to determine parameters of clinical presentations that might impact the disease progression pattern and outcome...

OBJECTIVE: We sought to determine whether abnormalities in emotion processing underlie functional (psychogenic) dystonia, one of the most common functional movement disorders. METHODS: Motor and emotion circuits were examined in 12 participants with functional dystonia, 12 with primary organic dystonia, and 25 healthy controls using functional magnetic resonance imaging at 4T and a finger-tapping task (motor task), a basic emotion-recognition task (emotional faces task), and an intense-emotion stimuli task...

PURPOSE: To investigate if psychiatrists could predict the diagnosis of psychogenic nonepileptic seizures (PNES) by reviewing videos of seizures of various types and to compare the accuracy and the criteria leading to the diagnosis used by psychiatrists with those used by epileptologists. METHODS: Four board-certified psychiatrists were asked to review 23 videos capturing representative events of 21 unselected consecutive patients admitted to an epilepsy center for long-term video-EEG monitoring...

The thalamus is a critical module in the circuit which has been associated with movement disorders including dystonia. This circuit extends from cortex to striatum to pallidum to the thalamic nucleus Ventral Lateral anterior (VLa) to cortex and can be studied by activity recorded during thalamic stereotactic surgery for the treatment of dystonia. Neuronal recordings in the VLa nucleus show low frequency modulation of firing that is correlated with and leads the low frequency modulation of EMG activity; this EMG activity is characteristic of dystonia...

S Noachtar, B Güldiken
Non-epileptic paroxysmal disorders may clinically manifest in a similar way to epileptic seizures and have to be considered in the differential diagnosis of epilepsy. Syncope, non-epileptic psychogenic seizures, paroxysmal movement disorders, migraine, transient ischemic attacks and parasomnia constitute the major differential diagnoses. A meticulous history and a third party description are useful for the differential diagnosis. Neurological, psychiatric and cardiological examinations are required for the correct differential diagnosis...

This case is an addition to scarce literature available for a rare condition, chewing-induced task-specific dystonia. The patient was a 63-year-old woman who presented with a 4-year history of progressive difficulty in eating food only during chewing associated with abnormal facial grimaces without any difficulty in drinking, swallowing, speaking or singing. Examination revealed dystonia of facial muscles every time she chewed but absent during drinking and speaking. As movements were consistent and reproducible with the specific task, other differential diagnosis like motor tics, psychogenic disorder, tardive dystonia and parkinsonism syndrome were excluded leading to a diagnosis of task-specific facial dystonia triggered by chewing...

The name functional rather than psychogenic is getting to be more widely used for terminology of this condition. It is better accepted by patients and keeps an open mind in searching for greater understanding of the pathophysiology. Advances in the pathophysiology show an overactive limbic system with connections to the motor system. Moreover, there is a disruption of the self-agency network, possibly due to a failure of feedforward signaling. There has recently been more success in treating patients. The strongest evidence is for intensive physical therapy coupled with at least some psychological support...

Functional (psychogenic) movement disorders (FMDs) may present with a broad spectrum of phenomenology including stereotypic movements. We aimed to characterize the phenomenology of functional stereotypies and compare these features with those observed in 65 patients with tardive dyskinesia (TD). From a cohort of 184 patients with FMDs, we identified 19 (10.3%) with functional stereotypies (FS). There were 15 women and 4 men, with a mean age at onset of 38.6 ± 17.4 years. Among the patients with FS, there were 9 (47%) with orolingual dyskinesia/stereotypy, 9 (47%) with limb stereotypies, 6 (32%) with trunk stereotypies, and 2 (11%) with respiratory dyskinesia as part of orofacial-laryngeal-trunk stereotypy...

Blepharospasm is an uncontrolled spasmodic contraction of the orbicularis muscles of the eye resulting in an abnormal tic or twitch of eyes. It usually lasts for seconds to minutes but in severe cases eyes may be closed for hours. It may be essentially benign or secondary due to a lesion in basal ganglia, pyramidal tract, and trauma, local pathology in the eyes or drug induced. Here we are presenting a case of psychogenic blepharospasm. A 65 year old woman presented with a history of episodic inability of opening her eyes for the past 6 months...

OBJECTIVE: Psychogenic movement disorder (PMD) and psychogenic nonepileptic seizures (PNES) are two subtypes of conversion disorder (CD). In this case-control study, we asked whether these subtypes varied as a function of personality and history of childhood abuse. METHODS: Fifty-nine patients with PMD from the Human Motor Control Section Clinic at the National Institutes of Health, 43 patients with PNES from the Rhode Island Hospital Neuropsychiatry and Behavioral Neurology Division, and 26 healthy volunteers (HC) received a battery of neurological, psychiatric and psychological assessments, including the NEO Personality Inventory Revised (NEO PI-R), the Childhood Trauma Questionnaire (CTQ), and the Traumatic Life Events Questionnaire (TLEQ)...

A disorder of infants and children with pathological startle response, features of other system involvement, falls, and stiffness with retained consciousness. It should be differentiated from conditions such as myoclonic epilepsy, psychogenic movement disorder, Isaac syndrome, Schwartz-Jampel syndrome, Gilles de la Tourette, and culture-specific startle syndromes such as jumping Frenchman of Maine. A 5-year-old child symptomatic with repeated falls spontaneously as well as by sound and activities since neonatal period...

Psychogenic nonepileptic seizures (PNES) are defined as paroxysmal episodes in which epileptic semiology features are manifested, without the characteristic concomitant electrical discharges seen in epileptic seizures. Although many studies have dealt with semiologic classification of PNES, most of the studies did not raise the question of consistency of PNES in the same patient. The aim of this study was to measure the degree of consistency of PNES among individual patients. We retrospectively reviewed medical records and video- EEG records of all adult patients who underwent monitoring in our center from August 1st 2013 to May 31st 2015...

A movement disorder emergency has been defined by Fahn and Frucht as "any neurological disorder evolving acutely or subacutely, in which the clinical presentation is dominated by a primary movement disorder, and in which failure to accurately diagnose and manage the patient may result in significant morbidity or even mortality." In this review, we discuss the most common situations in which hyperkinetic movement disorders, including chorea, ballism, dystonia, myoclonus, tics, as well as psychogenic disorders, can present as emergencies...

BACKGROUND: Movement disorders associated with complex regional pain syndrome type I have been a subject of controversy over the last 10 years regarding their nature and pathophysiology, with an intense debate about the functional (psychogenic) nature of this disorder. The aim of this study was to test sensorimotor plasticity and cortical excitability in patients with complex regional pain syndrome type I who developed a fixed posture of the hand. METHODS: Ten patients with complex regional pain syndrome type I in the right upper limb and a fixed posture of the hand (disease duration less than 24 months) and 10 age-matched healthy subjects were enrolled...

Early motor symptoms of neurodegenerative diseases often appear in combination with psychiatric symptoms, such as depression or personality changes, and are in danger of being misdiagnosed as psychogenic in young patients. We present the case of a 32-year-old woman who presented with rapid-onset depression, followed by a hypokinetic movement disorder and cognitive decline during pregnancy. Genetic testing revealed a mutation in the colony-stimulating factor 1 receptor gene, which led to the diagnosis of hereditary diffuse leukoencephalopathy with spheroids...
