Purpose: Neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody disease (MOGAD) are immune-mediated disorders that can often manifest with optic neuritis (ON) among other symptoms. Optical coherence tomography angiography (OCTA) is an emerging diagnostic method that can quantify retinal capillary blood flow and vessel density (VD), which have been shown to be affected in NMOSD and MOGAD. Hence, we aimed to systematically review the studies addressing retinal microvasculature using OCTA in these diseases.

Typical ON is often idiopathic or seen in patients with multiple sclerosis, which is well described in the landmark clinical trial, the Optic Neuritis Treatment Trial (ONTT). However, since the completion of the ONTT, there has been the discovery of aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) antibodies, which are biomarkers for neuromyelitis optica spectrum disorder (NMOSD) and MOG antibody-associated disease (MOGAD), respectively.

Neurological manifestations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have recently been reported. In this case report, we present a patient with encephalopathy as a late neurologic manifestation of SARS-CoV-2 infection.

Among these is Guillain-Barre syndrome and its variants, including facial diplegia. In this case we present a patient with facial diplegia following a confirmed SARS-CoV-2 infection.

GNE myopathy is an autosomal-recessive distal myopathy. It is caused by a hypomorphic GNE gene, encoding the rate-limiting enzyme in sialic acid synthesis. This myopathy is prevalent in the Iranian Jewish (IJ) descendants because of a founder mutation GNE: p.
View Article and Find Full Text PDFTuberculous granulomatous vasculitis is commonly associated with meningitis and retinitis. We describe a 39-year-old male, with a history of pulmonary tuberculosis (TB) who presented with progressive weakness, pain, tingling and numbness in the bilateral lower extremities. Significant atrophy and weakness of the lower extremities were evident along with absent reflexes.

Objective: The presence of repetitive behaviors is one of the core criteria for behavioral variant frontotemporal dementia (bvFTD). Patients with bvFTD often have perseverative, stereotyped, or compulsive-ritualistic behavior as an early aspect of their disorder. It is unclear whether such behaviors are related to compulsions, as in obsessive-compulsive disorder (OCD), or are part of the impulse disorder spectrum.

The objective of this analysis is to study the life of Hans Gustav Wilhelm Steinert and his role in identifying several neurologic disorders including myotonic dystrophy (DM). DM type 1 (DM1) is a commonly inherited adult muscle disorder. In 1909, its characteristics were first described by Hans Steinert (1875-1911), a German neurologist.
View Article and Find Full Text PDFBackground: Many patients with early-onset Alzheimer's disease (EOAD; age of onset <65 years) have non-amnestic presentations involving language (logopenic primary progressive aphasia, lvPPA), visuospatial abilities (posterior cortical atrophy, PCA), and even asymmetric symptoms consistent with corticobasal syndrome (CBS). An inferior parietal lobule variant of EOAD commonly presents with progressive difficulty with calculations.
Methods: We reviewed 276 EOAD patients for presentations with predominant acalculia.
Objective: This study aimed to discuss a case of a patient with a known diagnosis of Parry-Romberg syndrome (PRS) presenting with ischemic stroke, the second such reported case.
Background: PRS is a rare genetic disorder with progressive hemifacial atrophy, which usually presents within the first 2 decades of life. Neurologic manifestations include trigeminal neuralgia with associated deafness, hemifacial pain with associated migraine headaches, seizures, movement disorders, and neuropsychiatric symptoms.
Background: The neural substrates of meditation are not well understood. Meditation is theorized to be a conscious mental process that induces a set of complex physiological changes within the areas of the brain termed as the "relaxation response."
Aims And Objective: Pilot data of a functional magnetic resonance imaging (fMRI) study is presented to observe and understand the selective activations of designated brain regions during meditation.
Background: Deficits in instrumental activities of daily living (ADLs) may be more prominent in behavioral variant frontotemporal dementia (bvFTD) than in nonfluent/agrammatic variant primary progressive aphasia (nfvPPA) or semantic variant primary progressive aphasia (svPPA). It is uncertain whether frontotemporal dementia (FTD) subgroups exhibit different patterns and/or predictors of functional impairment.
Methods: We examined data from participants diagnosed with bvFTD (n = 607), svPPA (n = 132), and nfvPPA (n = 155) who were included in the National Alzheimer's Coordinating Center (NACC) Uniform Data Set (UDS) and assessed with the Functional Activities Questionnaire (FAQ).
