syncopal seizure

Rangaswamy, V Ranjith, L Vikas, R Santosh
Fahr's disease or Fahr's syndrome is a rare neurodegenerative disorder characterized by abnormal symmetrical calcifications of the basal ganglia, thalami, sub-cortical hemispheric white matter and deep cerebellar nuclei. It can be idiopathic or associated with an endocrinopathy, frequently with parathyroid disorder. Clinical spectrum of the disease is wide ranging from neurological features like seizure, syncope, stroke like events, extra-pyramidal symptoms often combined with frontal sub-cortical pattern of behavioural dysfunction and psychiatric symptoms such as psychosis, mood disorder and dementia...

In the investigation of psychogenic nonepileptic seizures (PNES), the main differential diagnoses are between convulsive PNES and tonic-clonic seizures, between swoon PNES and syncope, and between pseudoabsence PNES and absence seizures. For the best diagnostic certainty, events must be captured, ideally using video-electroencephalogram (EEG), including an electrocardiographic channel. The "video" part of video-EEG allows EEG changes (or lack of them) to be interpreted in the appropriate clinical context. When the diagnosis is based on less good data (e...

Psychogenic nonepileptic seizures (PNES) superficially resemble epileptic seizures or syncope and most patients with PNES are initially misdiagnosed as having one of the latter two types of transient loss of consciousness. However, evidence suggests that the subjective seizure experience of PNES and its main differential diagnoses are as different as the causes of these three disorders. In spite of this, and regardless of the fact that PNES are considered a mental disorder in the current nosologies, research has only given limited attention to the subjective symptomatology of PNES...

Stroke services have been centralised in several countries in recent years. Diagnosing acute stroke is challenging and a high proportion of patients admitted to stroke units are diagnosed as a non-stroke condition (stroke mimics). This study aims to describe the stroke mimic patient group, including their impact on stroke services. We analysed routine clinical data from 2,305 consecutive admissions to a stroke unit at St George's Hospital, London. Mimic groupings were derived from 335 individual codes into 17 groupings...

Medical emergencies that are life threatening can occur in dental practice. Complications may arise because of an underlying disease or a reaction to medication. Reactions to medications may be allergic and toxic. The most common reactions are toxic reactions to local anesthetics, whereas allergies occur mainly as a consequence of the application of antibiotics, usually penicillin. In response to stress, vasovagal syncope typically occurs. Other causes may be related to an underlying disease-specific pathology (such as acute asthma attack, diabetic ketoacidosis, hypoglycemia, or seizures) or accidents (aspiration of a foreign body causing obstruction of the respiratory system)...

OBJECTIVE: Cardiorespiratory function alterations are commonly observed with epileptic seizures and may lead to syncope and sudden unexpected death in epilepsy (SUDEP). Although most previous research has focused on controlling heart rate (HR) and respiration, little is known about seizure-related regulation of systemic blood pressure (BP). Herein, we have investigated whether the periictal modulation of systemic BP and HR depends on seizure characteristics. METHODS: Systemic arterial BP, HR, and peripheral capillary oxygen saturation (SPO2 ) were continuously and noninvasively monitored using the ccNexfin device in those epilepsy patients undergoing video-electroencephalography (EEG) telemetry...

We sought to characterize the clinical features of tilt-induced psychogenic nonsyncopal collapse (PNSC) from a cohort of young patients and to compare the semiologies between PNSC and EEG-confirmed psychogenic nonepileptic seizures (PNES). A PNSC diagnosis was made if a clinical event occurred during tilt-table testing that the patient regarded as fainting, but neither hypotension nor EEG changes were present. A diagnosis of PNSC was made in 17.6% of all patients referred during the 15-month study period. Cohorts with psychogenic nonsyncopal collapse (n=40) and PNES (n=40) did not differ in age (15...

BACKGROUND: Long QT syndromes (LQTS) are characterized by prolonged QTc interval on electrocardiogram (ECG) and manifest with syncope, seizures or sudden cardiac death. Long QT 1-3 constitute about 75% of all inherited LQTS. We classified a cohort of Indian patients for the common LQTS based on T wave morphology and triggering factors to prioritize the gene to be tested. We sought to identify the causative mutations and mutation spectrum, perform genotype-phenotype correlation and screen family members...

Vagoglossopharyngeal neuralgia (VGPN) is a very rare condition. VGPN with convulsive like attack is even rarer All of the cases had their head turned to the opposite side of facial pain. Hemifacial spasm occurring concurrently with VGPN has never been reported. Herein, we present the first case of VGPN that had ipsilateral hemifacial spasm and versive seizure-like movement to the same side of facial pain. We reported a 71-year-old man presenting with multiple episodes of intermittent sharp shooting pain arising on the right middle neck, followed by hemifacial spasm on right face...

It is important but difficult to distinguish convulsive syncope from epileptic seizure in many patients. We report a case of a man who presented to emergency department after several witnessed seizure-like episodes. He had a previous medical history of systolic heart failure and automated implantable converter defibrillator (AICD) in situ. The differential diagnoses raised were epileptic seizures and convulsive syncope secondary to cardiac arrhythmia. Subsequent AICD interrogation revealed ventricular tachycardia and fibrillation (v-tach/fib)...

INTRODUCTION: The effect of the single seizure clinic (SSC) model on patient diagnose, work-up, wait-times, and clinical care is poorly characterized and its efficacy unclear. The present study assesses patient characteristics and evaluates the impact of a single seizure clinic (SSC) model on wait-times and access to care. MATERIAL AND METHODS: A prospective study of all patients (n=200) referred to our SSC for first seizure evaluation. Demographic, clinical, and paraclinicial variables were systematically collected and analyzed against a historical cohort...

BACKGROUND: Syncope is commonly worked up for carotid stenosis, but only rarely attributed to it. Considering paucity of such cases in literature, we report a case and discuss the pathophysiology. DESIGN/METHODS: We report a patient with high-grade bilateral severe internal carotid artery (ICA) stenosis who presented with syncopal episodes in the absence of stroke, orthostatic hypotension, significant cardiovascular disease, or vasovagal etiology. We reviewed all literature pertaining to syncope secondary to carotid stenosis and other cerebrovascular disease...

OBJECTIVE: Epileptic seizures, syncope, and psychogenic nonepileptic seizures (PNES) account for over 90% of presentations with transient loss of consciousness (TLOC). The patient's history is crucial for the diagnosis, but the diagnostic value of individual semiologic features is limited. This study explores the diagnostic potential of a comprehensive questionnaire focusing on TLOC-associated symptoms. METHODS: A total of 386 patients with proven epilepsy, 308 patients with proven PNES, and 371 patients with proven syncope were approached by post to recruit 100 patients in each diagnostic group...

PURPOSE: The diagnostic classification of disorders of consciousness is often challenging, particularly the distinction between epileptic and non-epileptic seizures. The aim of the study was to examine serum lactate as a diagnostic marker of transient loss of consciousness. METHOD: Serum lactate levels in blood samples drawn within 2h of the event were compared retrospectively between patients with generalized tonic-clonic seizures (n=195) and patients with other seizures (syncopes [n=52], psychogenic non-epileptic seizures [n=17], and complex focal seizures [n=37]), respectively...

Mechanical circulatory assist devices are now commonly used in the treatment of severe heart failure as bridges to cardiac transplant, as destination therapy for patients who are not transplant candidates, and as bridges to recovery and "decision-making". These devices, which can be used to support the left or right ventricles or both, restore circulation to the tissues, thereby improving organ function. Left ventricular assist devices (LVADs) are the most common support devices. To care for patients with these devices, health care providers in emergency departments (EDs) and intensive care units (ICUs) need to understand the physiology of the devices, the vocabulary of mechanical support, the types of complications patients may have, diagnostic techniques, and decision-making regarding treatment...

Long QT syndrome (LQTS) is an arrhythmogenic cardiac disorder resulting from the malfunction of cardiac ion channels. Patient with LQTS may present with syncope, seizures or sudden cardiac death secondary to polymorphic ventricular tachycardia (VT) or torsades de pointes. Patient may be asymptomatic in the pre-operative period but may develop VT for the first time in operation theatre. We are reporting anaesthetic management of a child with LQTS planned for bilateral thoracoscopic cervicothoracic sympathectomy...

A 25-year-old previously healthy man was hospitalized for syncope. While standing, he suddenly lost consciousness, followed by a generalized tonic clonic seizure. An electrocardiogram demonstrated asystole. No cardiac abnormalities were detected on the echocardiogram, cardiac magnetic resonance imaging (MRI), positron emission tomography, or a coronary angiogram. An electrophysiological study showed normal sinus node and atrioventricular node function. An electroencephalogram revealed small spike waves in the fronto-temporal region...
