Approach to Common Visual Complaints Presenting to the Outpatient Neurologist.

Visual complaints are commonly encountered by the practicing neurologist. We review assessment of vision loss, diplopia, and positive visual phenomena, all of which require a thoughtful evaluation to localize disease and refine management. While many causative entities are unlikely to cause poor visual outcomes, including dry eyes, migraine, and congenital strabismus, others may threaten vision, life, or both, such as posterior communicating artery aneurysms, pituitary apoplexy, or temporal arteritis.

Orbital Apex Syndrome Secondary to Invasive Aspergillus Infection: A Case Series and Literature Review.

Background: Invasive fungal sinusitis carries high morbidity and mortality and often poses a diagnostic challenge. Orbital apex syndrome (OAS) is not an uncommon presentation in the setting of invasive fungal sinusitis. Delays in diagnosis and appropriate treatment can result in permanent visual dysfunction and, potentially, death.

Vision loss, gaze palsy, and nystagmus in a patient with leukemia.

A 22-year old male with a history of B-cell acute lymphoblastic leukemia with recent bone marrow transplantation and on immunosuppressive therapy presented with painless, subacute vision loss of two weeks duration. He exhibited a horizontal gaze palsy, nystagmus, and mildly swollen and hyperemic optic discs with peripapillary flame hemorrhage on retinal exam. He had bilateral cecocentral scotomas on visual field exam, and MRI of his brain/orbits demonstrated hyperintensities in the hypothalamus, periaqueductal gray, and dorsal rostral medullary regions.

The Role of Nutrition in Individualized Alzheimer's Risk Reduction.

Purpose Of Review: Decades of research suggests nutritional interventions can be an effective tool for reducing risk of Alzheimer's disease (AD), especially as part of an individualized clinical management plan. This review aims to emphasize new findings examining how specific dietary changes may delay or possibly prevent AD onset, and highlight how interventions can be adopted in clinical practice based on emerging principles of precision medicine.

Recent Findings: Specific dietary patterns and varied nutrient combinations can have a protective effect on brain health, promote cognitive function, and mediate the comorbidity of chronic conditions associated with increased AD risk.

Individualized clinical management of patients at risk for Alzheimer's dementia.

Introduction: Multidomain intervention for Alzheimer's disease (AD) risk reduction is an emerging therapeutic paradigm.

Methods: Patients were prescribed individually tailored interventions (education/pharmacologic/nonpharmacologic) and rated on compliance. Normal cognition/subjective cognitive decline/preclinical AD was classified as Prevention.

Myopathic Blepharoptoses: A New Classification System.

Purpose: Myopathic blepharoptoses (ptoses) is a complex group of disorders. To date, no formal categorization scheme has been developed based on associated ocular and systemic findings, genetic fingerprint, treatment, and prognosis for each ptosis in this group. We report a new classification scheme for myopathic ptoses.

Increased regional epicardial fat volume associated with reversible myocardial ischemia in patients with suspected coronary artery disease.

Epicardial adipose tissue is a source of pro-inflammatory cytokines and has been linked to the development of coronary artery disease. No study has systematically assessed the relationship between local epicardial fat volume (EFV) and myocardial perfusion defects. We analyzed EFV in patients undergoing SPECT myocardial perfusion imaging combined with computed tomography (CT) for attenuation correction.

Cigarettes, genetic background, and menopausal timing: the presence of single nucleotide polymorphisms in cytochrome P450 genes is associated with increased risk of natural menopause in European-American smokers.

Objective: This study aims to evaluate associations between variations in genes involved in the metabolism of environmental chemicals and steroid hormones and risk of menopause in smokers.

Methods: Survival analysis was performed on 410 eligible participants from the Penn Ovarian Aging study (ongoing for 14 years), a cohort study of late-reproductive-age women. Single nucleotide polymorphisms at the following loci were studied: COMT Val158Met, CYP1B1*4 Asn452Ser, CYP1B1*3 Leu432Val, and CYP3A4*1B.

Alzheimer's disease.

Alzheimer's disease (AD) is the most common neurodegenerative cause of dementia and is responsible for significant individual morbidity and mortality, and economic impact on the health care system. Neurodegeneration (including neuronal atrophy and/or loss) are attributed to extraneuronal toxic amyloid oligomers and proteins, intraneuronal neurofibrillary tangles consisting of hyperphosphorylated tau, region-specific diminished cerebral glucose metabolism, synaptic dysfunction, and mitochondrial dysfunction. Several of these pathologic changes may occur decades before symptom onset, leaving ample time for implementing prevention strategies that target the earliest stages of the disease.

Epicardial fat volume in patients with left ventricular systolic dysfunction.

Epicardial adipose tissue has been linked to cardiovascular metabolism and inflammation and has been shown to predict prevalence and progression of coronary artery disease. Only limited data are available on the role of epicardial fat in patients with heart failure (HF). We analyzed cardiac adiposity and its relation to markers of morbidity and clinical outcome in patients with normal and impaired left ventricular (LV) function.

Young children in early-onset Alzheimer's disease families: research gaps and emerging service needs.

Early-onset Alzheimer's disease (EOAD), defined as affecting those under age 65, afflicts between 200,000 and 500,000 people in the US. EOAD tends to be a fast-progressing and aggressive form of AD. There is a beginning body of research exploring EOAD patients' experience and needs, as well as that of their primary family caregivers, often spouses.
