Single-Case Neuropsychological Assessment of a Patient with a Posterior Parietal Lesion Using Behavioral Testing and Resting-State fMRIby
Abstract
This study integrated functional connectivity measures using resting-state fMRI and behavioral data from a single-case observation of patient (PER) one year after right-hemispheric hemorrhage in the intraparietal sulcus and superior parietal lobule (IPS/SPL). PER showed no sign of clinical neglect. Her behavioral performance in the visuo-manual pointing task and in the letter discrimination task under conditions of endogenous and exogenous attentional cueing was compared between the left (affected) and right (unaff [...] 1981 11324 |
Genetic, Social and Behavioral Risk Factors Associated with Alzheimer’s DiseaseAbstract
Alzheimer’s disease (AD) is a neurodegenerative condition which consists of stages of mental, memory, and cognitive decline. As it continues to stand as the sixth leading cause of death in the U.S., 44 million people worldwide are affected. The objective of this paper is to explore the risk factors for AD in an attempt to examine potential causes for the incidence of AD. We examined genetics, lifestyle, and pre-existing conditions as risk factors for AD. We found that there are various alleles, such as APP, P [...] 1854 10847 |
Why the Quantum Brain?Abstract
This article reviews the modern approaches to the quantum brain hypothesis. The aim is to consider the hypothesis and its classical brain-machine alternative from a broad perspective, including physics, biology, computer science, cosmology, and metaphysics. My starting point is that asking whether consciousness can or cannot have free will is fundamentally incorrect. This aspect is challenged by both physics and neuroscience. The paper argues that the search for conscious free will, as it is typically tested in Lib [...] 2449 23446 |
Psilocybin as a Novel Pharmacotherapy for Treatment-Refractory Anorexia NervosaAbstract
Anorexia Nervosa (AN) is a major health problem with one of the highest mortalities and treatment costs of any psychiatric condition. Cognitive behavioural therapy (CBT) is currently the most widely used treatment for AN in adults but provides remission rates ≤ 50%. Treatment drop-out is exceedingly high and those that persevere with treatment often relapse, causing increased risk of morbidity and mortality. There is an urgent need to find new interventions, especially as there are no approved pharmacological treat [...] 4228 34881 |
Establishing and Evaluating a Multidisciplinary Community-Based Sleep Clinic for Children with Neurodevelopmental Difficulties in Inner LondonAbstract
We describe our experience of setting up and evaluating a community-based multi-disciplinary sleep service for children with neurodevelopmental disorders and psychosocial vulnerabilities.Referrals are accepted for children (1-18 years of age) with persistent sleep problems, and neurodevelopmental difficulties or significant psychosocial adversity, living in two inner-city boroughs.Holistic sleep assessment involves 1-hour Paediatrician-led consultation, often followed by Psychologist-led parent workshop, with follo [...] 2000 10307 |
The Trails Making Test. Does a Single Trial Reflect Performance Capability?Abstract
Information processing speed (Reaction time, RT) to a single administration of the Trails A and Trails B components of the Trail Making Test (TMT) is used in the assessment of brain and behavioural functional integrity across the lifespan in both clinical and research contexts. Although the clinical utility of such single trial-related and thus rapidly gained results, is recognised, it is possible that its administration as a single trial only, precludes its ability to provide a more in-depth and thus relevant repr [...] 2640 35568 |
Management of Agitation, Delirium, and Catatonia in Intubated COVID-19 Patients: A Case Series & Rationale for Valproate Sodium Use During Extubationby
Abstract
The complete spectrum of neuropsychiatric effects of SARS-CoV-2 acute respiratory distress syndrome has yet to be fully appreciated, particularly in intubated patients. Manifestations including delirium and catatonia need to be considered in intubated COVID-19 patients. Medications known to exhibit neuroprotective effects, like valproate, can assist in agitation related to sedative withdrawal during extubation. This case series reports on the management of agitation, delirium, and catatonia in COVID-19 patients dur [...] 3651 17520 |
Ocular Pressure-Volume Relationship and Ganglion Cell Death in Glaucomaby
Abstract
We studied how GC death in glaucoma related to the intraocular pressure (IOP), eyeball volume (VS) and elasticity (volumetric KS and tensile ES), and eyeball volume-pressure relation. Glaucomatous GC loss was studied in DBA/2J (D2) mice with wild-type mice as controls. GCs were retrogradely identified and observed with a confocal microscope. The elasticity calculation was also done on published data from patients treated by a gas bubble injection in the vitreous cavity. The GC population in D2 mice (1.5- to 14-mont [...] 2354 11989 |
A Systematic Review of the Biological Processes Involved in Deep-Brain Stimulation for Parkinson's disease: A Focus on the Potential Disease-Modifying Effectsby
Abstract
Deep-Brain Stimulation (DBS) is an important treatment option for the management of Parkinson’s disease (PD) and is a common symptomatic treatment. However, an increasing number of studies have examined the biological processes to assess if DBS can also modify the natural history of PD by acting on its pathophysiological mechanisms. Relevant literature published up to November 2020 was systematically searched on databases such as PubMed, ISI Web of Knowledge, Academic Search Index, and Science Citation Index. The f [...] 1804 11864 |
Examining the Role of Specialized DNA Polymerases in the Development of Temozolomide Resistance in Glioblastoma MultiformeAbstract
Glioblastoma multiforme (GBM) is an extremely malignant type of primary brain tumor that exhibits a high mortality rate. Current standard therapy involves surgery followed by radiation and treatment with the DNA-alkylating agent, temozolomide (TMZ). While TMZ treatment can extend post-operative survival, most patients develop resistance to TMZ which leads to a significant increase in mortality. At the molecular level, TMZ produces a variety of different DNA lesions including N7-methylguanine, N3-methyladenine, and [...] 2030 12900 |
