This historical note highlights pivotal events of technology progressing between the late 19th and the 20th century to capture functional seizures and other related seizure episodes. From Charcot's initial use of photography for his study of hysteria at the Salpêtrière to the development of cinematography by Muybridge and Marey to study motion to the initial use of video electroencephalography (vEEG) through a pairing of cinematography with EEG, and the advent of EEG telemetry to eventually the development of modern epilepsy monitoring unit through the adoption of cameras and an improved long-term monitoring vEEG system.

The impact of the collaboration between photographer Eadweard Muybridge and neurologist Francis Dercum is detailed within the context of a photographic study of an artificially induced psychogenic non-epileptic seizure. Their contribution served as inspiration to other contemporary European neurologists and photographers to use motion photography to further understand psychogenic neurological disorders, such as seizures.

The painting Portrait of My Father (1951) by the Mexican painter, Frida Kahlo, is discussed by the author within the context of epilepsy and biographical events in the lives of both Frida and her father, the German Mexican photographer Guillermo Kahlo. The biographical accounts of the photographer's seizures are suggestive of juvenile absence epilepsy but cannot discount the possibility of posttraumatic epilepsy of mesial frontal origin.

Purpose: Dalfampridine extended-release (ER) tablets 10 mg BID have been approved for use in improving walking in people with multiple sclerosis (MS). This subgroup analysis evaluated the effects of dalfampridine ER 5 and 10 mg BID on distance walked, as assessed using the 6-minute walk (6MW) test.

Methods: This analysis of data from a randomized, placebo-controlled, double-blind study (N = 430) included only the 153 patients with 6MW data available.

Background: Dalfampridine extended-release (ER) tablets, 10 mg twice daily, have been shown to improve walking in people with multiple sclerosis. We evaluated the safety and efficacy of dalfampridine-ER 5 mg compared with 10 mg.

Methods: Patients were randomized to double-blind treatment with twice-daily dalfampridine-ER tablets, 5 mg (n = 144) or 10 mg (n = 143), or placebo (n = 143) for 4 weeks.

Objective: To determine the feasibility of administering a diazepam nasal spray formulation (diazepam-NS) to adults with epilepsy during a generalized tonic-clonic seizure or in the postictal period following a tonic-clonic or other seizure type, to assess pharmacokinetics and to assess tolerability.

Methods: An open-label study was conducted in patients admitted to the epilepsy monitoring unit. Eligible patients received a single dose of diazepam-NS approximating 0.

Diazepam rectal gel (RG) is currently the only approved rescue therapy for outpatient management of seizure clusters in the United States. There is an unmet medical need for an alternative rescue therapy for seizure clusters that is effective, and more convenient to administer with a socially acceptable method of delivery. An intranasal diazepam formulation has been developed, and this study evaluates the tolerability and bioavailability of diazepam nasal spray (NS) relative to an equivalent dose of diazepam-RG in healthy adults.

Excessive daytime sleepiness (EDS) is common in the general population. Etiologies include insufficient sleep and primary sleep disorders. Due to its high prevalence, physicians often overlook EDS as a significant problem.

Praxis-induction of seizures is an interesting subset of reflex epilepsy in which seizures are induced by higher mental activities associated with the use of part of the body. Reflex traits have often been described in patients with juvenile myoclonic epilepsy. We report a patient presenting with praxis-induced myoclonic epilepsy at a late age.

Landau-Kleffner syndrome (LKS), or acquired epileptiform aphasia, is an epilepsy syndrome involving progressive neuropsychological impairment related to the appearance of paroxysmal electroencephalograph (EEG) activity. LKS appears to share a common pathophysiologic mechanism with continuous spike-wave of sleep (CSWS), acquired epileptic opercular syndrome (AEOS), and even benign childhood epilepsy with centrotemporal spikes (BECTS), with differentiating factors including age of onset, area of primary epileptogenicity, and severity of clinical presentation. This article covers the clinical, diagnostic, therapeutic, and prognostic features of LKS.

Objectives: To evaluate the safety, tolerability, and efficacy of oxcarbazepine in the treatment of painful diabetic neuropathy.

Methods: This was an open-label, 9-week trial, consisting of a 1-week prospective Screening Phase followed by an 8-week Treatment Phase. Treatment with oxcarbazepine was initiated at 150 mg/day, and the daily dose was doubled on a weekly basis and titrated to tolerability over 4 weeks, up to 1200 mg/day.

Mild cognitive impairment (MCI) is increasingly being conceptualized in the literature as a cognitive disturbance representing a transitional phase between normal aging and dementia. The operational definitions of MCI provide an opportunity for neuropsychologists to detect subtle deficit and monitor cognitive status sequentially in order to determine rate and degree of progression. More importantly, clinical and neuropsychological studies are needed that can better characterize which MCI patients are at greatest risk for conversion to dementia.
