Peripheral neuropathic pain, typified by the development of spontaneous pain or pain hypersensitivity following injury to the peripheral nervous system, is common, greatly impairs quality of life, and is inadequately treated with available drugs. Maladaptive changes in chloride homeostasis due to a decrease in the functional expression of ...

Amyotrophic lateral sclerosis (ALS) is a clinically heterogeneous disease and presents with varying degrees of upper motor and lower motor neuron involvement. In certain cases, diagnosis can be challenging even for an experienced neurologist. Electrophysiology supplements the physical examination for detection of lower motor neuron involvement and is combined with ...

Diffusion-weighted imaging (DWI) has revealed the reversal of often sizeable damage due to brainstem lesions in patients treated within 4.5 hours, and this reversibility of damage was strongly associated with early neurological improvement.1 In posterior circulation stroke, the reversibility of damage due to a DWI-detected lesion is poorly documented after ...

Importance  Preclinical stroke research has had a remarkably low translational success rate, and the clinical need for novel neuroprotective therapeutics has gone largely unmet, especially in light of the severe underuse of thrombolysis in acute ischemic stroke.

Objective  In this review, we aim to provide a ...

Medicare coverage plays an important role in innovative device-based therapy in a market with increasing medical device costs and scarce financial resources. In January 2014, the Centers for Medicare and Medicaid Services (CMS) implemented changes to coverage policies for items and services associated with investigational device exemption (IDE) studies.1 Medicare’s ...

Objective To report the clinical, neuropsychological, linguistic, imaging, and neuropathological features of a unique case of sporadic Jakob-Creutzfeldt disease in which the patient presented with a logopenic variant of primary progressive aphasia.

Design Case report.

Setting Large referral center for atypical memory and aging disorders, particularly Jakob-Creutzfeldt disease.

In this issue of Archives, McKeon et al1 report that 10 of 81 patients with stiff-man syndrome from the Mayo Clinic in Rochester, Minnesota, had serum and/or cerebrospinal fluid IgG antibodies that bound to fixed, permeabilized HEK293 cells (an immortalized human kidney line) that had been transfected to express the ...

A 62-year-old man with no significant medical history experienced fatigue, night sweats, hoarseness of voice, and dry cough, which were followed by vision disturbances in his left eye. He lost about 4.5 kg (10 lb) in just over a month. Three weeks later, he had difficulty recollecting his ...

Background Anti– N-methyl-D-aspartate receptor (NMDAR) encephalitis is a severe autoimmune disorder characterized by high intrathecal antibody synthesis. Little is known about the long-term follow-up of the cerebrospinal fluid antibody status.

Objective To describe persistent intrathecal antibody synthesis in a clinically healthy person 15 years after ...

The treatment of relapsing multiple sclerosis (MS) remains a rare beacon of success in the long campaign against neurological disease. The ready availability of a phase II clinical outcome (eg, gadolinium-enhancing lesion) that tracks a relevant phase III clinical outcome (eg, annualized relapse rate) is one of the major reasons ...

Parkinson disease is one of the most common neurodegenerative diseases associated with aging. At least 18 genetic loci and 13 disease-related genes for parkinsonism have been identified. Among them, PARK15 -associated parkinsonism, also referred to as parkinsonian-pyramidal disease (PPD), was found to be caused by mutations in the ...
