Pseudoseizures, clinical events that superficially resemble epileptic attacks but which are not associated with central nervous system paroxysmal activity, are often difficult to differentiate from epileptic seizures. To evaluate the frequency and clinical manifestations of pseudoseizures in children with intractable seizures, children admitted to a Comprehensive Epilepsy Unit received prolonged simultaneous EEG telemetry and video recording. Pseudoseizures occurred in 11 of 53 pediatric patients admitted during the study period. Eight of the 11 patients with pseudoseizures also had documented epileptic seizures. Clinical characteristics of pseudoseizures and epileptic seizures documented by TEEG-VR were compared. Degree and duration of the postictal state, incontinence, combativeness, relationship to stress, and response to anticonvulsant medication were useful differentiating criteria. Pseudoseizures are not unusual in pediatric patients, often occur concurrently with epileptic seizures, and may be difficult to diagnose. However, careful clinical observation may offer clues in differentiating pseudoseizures from epileptic seizures.

Two patients who incurred significant injuries during psychogenic seizures prompted us to do a telephone survey of self-injury and incontinence in 102 consecutive patients diagnosed with psychogenic seizures by EEG-closed-circuit TV (EEG-CCTV) monitoring. Seventy-three patients (or a close family member or friend) were reached by telephone and responded to our survey. During typical attacks of psychogenic seizures, 40% reported injuries, 44% reporting tongue biting, and 44% reported urinary incontinence. Suicide attempts were reported by 32% and were more common in those with self-injury and urinary incontinence. We compared the results of patients with psychogenic seizures with those of 30 patients with refractory epilepsy documented by ictal recordings, using a similar telephone survey. Injuries of all types were more commonly reported by epilepsy patients. Burn injuries were reported only by patients with epilepsy. Suicide attempts were more commonly reported by the psychogenic seizure group. Self-injury and incontinence are commonly reported by psychogenic seizure patients. In view of their significant association with suicide attempts, they may indicate an underlying depression.

A female infant had erythematous vesicular skin lesions over the whole body and extremities in the early infancy. These skin lesions then changed to hyperpigmentation in whorls and splashes. Seizure attack was noted at one month old. Skin biopsy showed dyskeratosis, acanthosis, pigmenti incontinence, and massive infiltration of eosinophils. So Incontinentia pigmenti was confirmed. She also had hallmarks of retinal involvement, including peripheral retinal ischemia and neovascularization, which were similar to those seen in retinopathy of prematurity. Cryopexy was performed in her left eye and the lesions regressed.

Ifosfamide, a nitrogen mustard derived alkylating agent commonly used in the treatment of solid tumors, has been associated with neurotoxicity in 5-33% of treated patients. Encephalopathy most often occurs during or shortly following drug administration, with increased drowsiness or irritability, confusion, hallucinations, visual blurring, extrapyramidal dysfunction, cranial nerve abnormalities, incontinence, generalized muscle twitching, seizures, and coma reported in infants, children, and older adults. While most reported neurologic abnormalities associated with ifosfamide have been reversible, encephalopathy resulting in death has occurred. We now report an infant who developed ifosfamide-induced encephalopathy, loss of developmental milestones, progressive brain atrophy, and cessation of cranial growth. This is the first case of cerebral atrophy and loss of developmental milestones that has been reported in a pediatric patient treated with ifosfamide. Given the efficacy of this anti-neoplastic agent and its increasing use in pediatrics, further investigation is indicated, especially in infants where brain growth is ongoing.

Three patients, two men of 21 and 38 years and a woman of 20 years old, showed atypical seizures with motor agitation without tongue bite, incontinence or postictal confusion. After extensive video-EEG registration frontal lobe epilepsia was diagnosed. This is a relatively recently recognized disease entity.

From September 1994 to April 1995, we encountered eight children, two boys and six girls, (aged 1 year 6 months to 9 years), presented with acute diarrhea followed by afebrile, generalized tonic-clonic seizures, or transient loss of consciousness with urine incontinence. Their biochemical data, including serum electrolyte levels, were within normal limits. The infective agent causing diarrhea was later proved by stool examination to be rotavirus, judged to be serotype G1 by reverse transcription - polymerase chain reaction (RT-PCR) typing. Cerebrospinal fluid (CSF) examinations performed in seven of the eight patients were within normal limits, and cultures for bacteria and virus were negative. The electroencephalograms (EEGs) performed from 1 to 13 days after seizure showed abnormal in six, and normal in two, patients. Follow-up EEGs, performed from 4 to 11 months after onset of seizure, were all normal. None had seizure recurrence despite the fact that no long-term anticonvulsant had been given. From observation here, the authors emphasize that there is a close relationship between rotavirus and afebrile seizure, and the course of afebrile seizure following rotavirus gastroenteritis is usually benign. Further studies are needed to elucidate the underlying pathogenesis.

Loss of consciousness and falling are the key features of syncope. Common accompaniments include tonic and myoclonic muscle activity, eye deviations, automatisms, vocalizations and hallucinations which may render the distinction from epileptic seizures difficult. Differential diagnosis is based on the specific features and not the mere presence of these phenomena. Recognition of syncope depends also on accurate information about precipitants, premonitory symptoms and postictal events: the absence of postictal confusion has been identified as the single most powerful factor discriminating syncope from epileptic seizures whereas incontinence and head injury are common in both conditions. Investigations such as electroencephalogram, tilt testing and postictal prolactin or creatine kinase levels may be helpful but are never diagnostic in isolation. Exceptionally, hypoxic and epileptic mechanisms interact within a single attack.

We report 10 cases of children with pseudoseizures who presented to a pediatric emergency department. Half of the patients were teenagers and seven were female. None of the patients had incontinence, and none was injured during the "seizure." All but one patient had invasive procedures or laboratory tests performed in the emergency department, and six of 10 patients were given anticonvulsants. Pseudoseizures are often confused with generalized tonic-clonic seizures.

Legionella is a frequent etiologic agent in the development of both nosocomial and community acquired pneumonias. Involvement of the nervous system is common in Legionella infections. We present a case of Legionnaires' disease which illustrates distinctive neurologic findings including delirium and cerebellar dysfunction. Furthermore, this paper reviews the neurological and psychiatric features of 609 Legionella infected patients with involvement of the nervous system. The most common signs were disorientation (58%), headache (52.4%), and somnolence (39.7%). Less frequent or rare were: cerebellar dysfunction (11.2%), hallucinations (8.4%), agitation or stupor (4.1%), affective disorders (3.1%), peripheral neuropathy (2.8%), pyramidal disturbances (2.1%), memory loss (1.6%), seizures (1.5%), cranial nerve palsies (1.5%), incontinence (0.7%), and extrapyramidal disturbances (0.3%). Cranial CT scans, cerebrospinal fluid findings, and nerve and muscle biopsies were usually unremarkable. Neuropathologic examinations failed to demonstrate specific characteristics. Hyponatremia and serum CPK level elevation were present in up to 89% and 50% of patients, respectively. Prognosis of disturbances of the nervous system was mainly good. We conclude that in the presence of definite neurological findings, pulmonary infection, hyponatremia, and CPK elevation Legionella infection should be considered.

Confusion between syncope and epileptic seizures is a common problem in clinical practice. Recently, new insights into the phenomenology of transient cerebral hypoxia have been gained from video analysis of experimentally induced syncope. Common elements of syncope include multifocal and generalized myoclonus, tonic body extension, automatisms, vocalizations, eye deviations and hallucinations. Thus, it is not the presence or absence of these features but their specific character that distinguishes syncope from epileptic seizures. Other clues for differential diagnosis include precipitating factors, premonitory symptoms and postictal events, such as tongue bites and postictal confusion, which has been identified as the single most powerful factor discriminating syncope from epileptic seizures. In contrast, incontinence and head injury are common in both conditions. Investigations such as electroencephalogram, tilt testing and postictal prolactin or creatine kinase levels may aid diagnosis but are never diagnostic in isolation. In rare cases, hypoxic and epileptic mechanisms may interact within one attack.
