Physician-Reported Perspectives on Myasthenia Gravis in the United States: A Real-World Survey.

Introduction: Myasthenia gravis (MG) is a rare, debilitating, chronic disorder caused by the production of pathogenic immunoglobulin G autoantibodies against the neuromuscular junction. A lack of real-world studies in rare diseases reflects a relatively limited understanding of the significant unmet needs and burden of disease for patients. We aimed to provide comprehensive real-world insights into the management and burden of MG from treating physicians in the United States (US).

Improving Patient-Centered Communication about Sudden Unexpected Death in Epilepsy through Computerized Clinical Decision Support.

Background: Sudden unexpected death in epilepsy (SUDEP) is a rare but fatal risk that patients, parents, and professional societies clearly recommend discussing with patients and families. However, this conversation does not routinely happen.

Objectives: This pilot study aimed to demonstrate whether computerized decision support could increase patient communication about SUDEP.

The direct cost of seizure events in severe childhood-onset epilepsies: A retrospective claims-based analysis.

Objective: The objective of the study was to assess the direct cost of medically treated seizure events in severe childhood-onset epilepsies. Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), and tuberous sclerosis complex (TSC) are representative conditions associated with frequent intractable seizures.

Methods: Commercial and Medicaid insurance claims from 2010 to 2015 were queried to identify patients with possible LGS, possible DS, or TSC, having ≥2 years of continuous insurance from the date of first epilepsy/seizure diagnosis or antiepileptic drug (AED) fill (index date).

Burden of illness in patients with possible Lennox-Gastaut syndrome: A retrospective claims-based study.

Objective: Lennox-Gastaut syndrome (LGS) is a severe and treatment-resistant epilepsy syndrome characterized by multiple subtypes of intractable seizures, moderate to severe cognitive impairment, and slow spike-wave complexes on electroencephalographic (EEG) recordings. Lennox-Gastaut syndrome is also associated with increased risk for injury, reduced quality of life, long-term disability, and early mortality. By evaluating private and public US medical insurance claims, we quantified healthcare utilization and direct costs in patients with possible LGS.

Association between antiepileptic drug dose and long-term response in patients with refractory epilepsy.

Seizures in patients with medically refractory epilepsy remain a substantial clinical challenge, not least because of the dearth of evidence-based guidelines as to which antiepileptic drug (AED) regimens are the most effective, and what doses of these drugs to employ. We sought to determine whether there were regions in the dosage range of commonly used AEDs that were associated with superior efficacy in patients with refractory epilepsy. We retrospectively analyzed treatment records from 164 institutionalized, developmentally disabled patients with refractory epilepsy, averaging 17years of followup per patient.

Multidisciplinary assessment and diagnosis of conversion disorder in a patient with foreign accent syndrome.

Multiple reports have described patients with disordered articulation and prosody, often following acute aphasia, dysarthria, or apraxia of speech, which results in the perception by listeners of a foreign-like accent. These features led to the term foreign accent syndrome (FAS), a speech disorder with perceptual features that suggest an indistinct, non-native speaking accent. Also correctly known as psuedoforeign accent, the speech does not typically match a specific foreign accent, but is rather a constellation of speech features that result in the perception of a foreign accent by listeners.

The prediction of change: normative neuropsychological trajectories.

While the application of normative standards is vital to the practice of clinical neuropsychology, data regarding normative change remains scarce despite the frequency of serial assessments. Based on 285 normal individuals, we provide co-normed baseline data with demographic adjustments and test-retest standardized regression based (SRB) models for three time points for several measures. These models delineate normal, expected change across time, and yield standardized z-scores that are comparable across tests.

Neurocognitive correlates of response to treatment in late-life depression.

Unlabelled: Depression is often associated with neurocognitive deficits in older adults, particularly in the domains of information processing speed, episodic memory, and executive functions. Greater neurocognitive dysfunction while depressed is associated with a less effective treatment response; however, questions remain about the specific variables that characterize patients showing low treatment response and persistent cognitive deficiencies.

Objectives: The authors examined neurocognitive variables that differentiated patients who showed robust versus weak responses to antidepressant therapy.

Responses to false physiological feedback in individuals with panic attacks and elevated anxiety sensitivity.

Participants with elevated anxiety sensitivity and a history of panic attacks were compared to a low anxiety comparison group with respect to physiological and subjective reactivity to false heart-rate feedback and reactivity to a priming procedure. Whereas accurate heart-rate feedback elicited minimal responses, participants across groups showed significant physiological and subjective responses to false feedback. High risk and low risk participants did not differ in heart-rate responses to false feedback, though panic attack frequency did predict physiological and subjective reactions to false feedback in the high risk group.
