Psychiatric adverse drug reactions (ADRs) have been reported with statin use, but the literature regarding statin-associated mood/behavioral changes remains limited. We sought to elicit information germane to natural history and characteristics of central nervous system/behavioral changes in apparent connection with statin and/or cholesterol-lowering drug use, and delineate mechanisms that may bear on an association. Participants (and/or proxies) self-referred with behavioral and/or mood changes in apparent association with statins completed a survey eliciting cholesterol-lowering drug history, character and impact of behavioral/mood effect, time-course of onset and recovery in relation to drug use/modification, co-occurrence of recognized statin-associated ADRs, and factors relevant to ADR causality determination...

Reactive astrocytosis and the subsequent glial scar is ubiquitous to injuries of the central nervous system, especially spinal cord injury (SCI) and primarily serves to protect against further damage, but is also a prominent inhibitor of regeneration. Manipulating the glial scar by targeting chondroitin sulphate proteoglycans (CSPGs) has been the focus of much study as a means to improve axon regeneration and subsequently functional recovery. In this study we investigate the ability of small interfering RNA (siRNA) delivered by a non-viral polymer vector to silence the rate-limiting enzyme involved in CSPG synthesis...

Spinal cord injury (SCI) is a common disease worldwide that causes permanent neuronal dysfunction without an effective treatment. Long propriospinal neurons (LPSNs) that are spared from injury play a key role in spontaneous recovery after SCI. Traumatic injury of the central nervous system can activate autophagy, which could be a target in the development of a new therapeutic strategy to prevent neuronal loss. Our research focused on whether autophagy is involved in the loss of LPSNs after introducing spinal cord injury in adult rats...

The interaction between T cells and the central nervous system (CNS) in homeostasis and injury has been recognized being both pathogenic (CD4+ T-helper 1 - Th1, Th17 and γδT) and ameliorative (Th2 and regulatory T cells - Tregs). However, in-depth studies aimed to elucidate the precise in the aged microenvironment and the dichotomous role of Tregs have just begun and many aspects remain unclear. This is due, not only to a mutual dependency and reciprocal causation of alterations and diseases between the nervous and T cell immune systems, but also to an inconsistent aging of the two systems, which dynamically changes with CNS injury/recovery and/or aging process...

Diseases of the central nervous system are the most common cause of mobility and cognitive impairment. Stroke is the leading cause of hospitalization in the Neurological Rehabilitation Departments. Age increases the risk of stroke, therefore monitoring basic medical parameters, including blood pressure especially under age of 65, is a very important part of preventive healthcare. According to data from the National Association of Stroke, in 10% of patients after brain stroke, recovery of motor functions and mental state is almost complete, in 25% impairment is minimal, in 40% the functional and cognitive disability is moderated or significant therefore requires rehabilitation, in 10% in view of impossibility of active rehabilitation patients requires comprehensive nursing care service at home or in special long term care centers...

The immune reconstitution inflammatory syndrome (IRIS) is a deregulated inflammatory response to invading microorganisms. It is manifested when there is an abrupt change in host immunity from an anti-inflammatory and immunosuppressive state to a pro-inflammatory state as a result of rapid depletion or removal of factors that promote immune suppression or inhibition of inflammation. The aim of this paper is to discuss and re-interpret the possibility of association of paracoccidioidomycosis (PCM) with IRIS in the central nervous system (CNS) in a case from Brazil published by Silva-Vergara ML...

Several in vitro and limited in vivo experiments have shown that neurons maintain a rest tension along their axons intrinsically. They grow in response to stretch but contract in response to loss of tension. This contraction eventually leads to the restoration of the rest tension in axons. However, the mechanism by which axons maintain tension in vivo remains elusive. The objective of this work is to elucidate the key cytoskeletal components responsible for generating tension in axons. Toward this goal, in vivo experiments were conducted on single axons of embryonic Drosophila motor neurons in the presence of various drugs...

Acute transverse myelitis is a rare manifestation of dengue infection. To the best of our knowledge, only 6 cases of acute transverse myelitis as a manifestation of dengue infection have been reported thus far. The present study described a case of acute transverse myelitis complicated with subacute thyroiditis 6 days after the onset of dengue viral infection. In addition, the available literature was searched to identify similar previous cases. Treatment with intravenous pulse methylprednisolone immunoglobulin plasmapheresis and physiotherapy resulted in partial recovery at 3 months post-infection...

INTRODUCTION: Primary central nervous system lymphoma (PCNSL) of T-cell origin is an exceptionally rare, highly malignant intracranial neoplasm. Although such a tumor typically presents with a focal mass lesion. CASE REPORT: Past medical history of a 26-year-old male patient with a PCNS lymphoma of T-cell origin was not suggestive of intracranial pathology or any disorder of other organs and organic systems. To achieve a gross total tumor resection, surgery was performed via osteoplastic craniotomy using the left frontal transcortical transventricular approach...

BACKGROUND Intracerebral hemorrhage (ICH) is one severe subtype of stroke, with a very complex pathology. Stem cell-based therapy holds promising potential in the treatment of neurological disorders. Human umbilical cord-derived mesenchymal stem cells (UC-MSCs) have a therapeutic effect in recovery from brain damage following ICH. The aim of this study was to identify an effective and convenient way of using UC-MSCs in the ICH rat model. MATERIAL AND METHODS CM-DiI-labeled human UC-MSCs were transplanted intracerebrally or intravenously into collagenase VII-induced ICH rat models...

Spinal cord injury (SCI) is a devastating condition that leaves patients with limited motor and sensory function at and below the injury site, with little to no hope of a meaningful recovery. Because of their ability to mimic multiple features of central nervous system (CNS) tissues, injectable hydrogels are being developed that can participate as therapeutic agents in reducing secondary injury and in the regeneration of spinal cord tissue. Injectable biomaterials can provide a supportive substrate for tissue regeneration, deliver therapeutic factors, and regulate local tissue physiology...

OBJECTIVE: Acute disseminating encephalomyelitis (ADEM) is an inflammatory demyelinating disease affecting the central nervous system and mainly occurs in young children. Children who initially presented with ADEM can be diagnosed with multiple sclerosis (MS) in case new non-encephalopathic clinical symptoms occur with new lesions on MRI at least three months after onset of ADEM. We aim to study the timing of MRI abnormalities related to the evolution of clinical symptoms in our Dutch paediatric ADEM cohort...

BACKGROUND: Adequate consumption of polyunsaturated fatty acids (PUFA) is vital for normal development and functioning of the central nervous system. The long-chain n-3 PUFAs docosahexaenoic acid (DHA) and eicosapentaenoic acid are anti-inflammatory and neuroprotective in the models of central nervous system injury including traumatic brain injury (TBI). In the present study, we tested whether a higher brain DHA status in a mouse model on an adequate dietary α-linolenic acid (ALA) leads to reduced neuroinflammation and improved spontaneous recovery after TBI in comparison to a moderately lowered brain DHA status that can occur in humans...

: : Research in the last decade strongly suggests that mesenchymal stem cell (MSC)-mediated therapeutic benefits are mainly due to their secretome, which has been proposed as a possible therapeutic tool for the treatment of Parkinson's disease (PD). Indeed, it has been shown that the MSC secretome increases neurogenesis and cell survival, and has numerous neuroprotective actions under different conditions. Additionally, using dynamic culturing conditions (through computer-controlled bioreactors) can further modulate the MSC secretome, thereby generating a more potent neurotrophic factor cocktail (i...

Astrocytes traditionally were thought to have merely a support function, but are now understood to be important regulators of neural development and function. The immature and mature astrocytes have stage-specific roles in neuronal development. However, it is largely unclear whether human astrocytes also serve stage-specific roles in oligodendroglial development. Owing to the broad and diverse roles of astroglia in the central nervous system, transplantation of astroglia also could be of therapeutic value in promoting regeneration after CNS injury or disease...

INTRODUCTION: Post-infectious encephalitis/encephalopathy is a neurological syndrome that sometimes develops following common viral or bacterial infections. The most common form is acute disseminated encephalomyelitis (ADEM). ADEM is a demyelinating disease of the central nervous system that typically presents as a monophasic disorder associated with multifocal neurologic symptoms and encephalitis. Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis is another type of severe autoimmune disorder, characterized by seizures, movement disorders and psychiatric symptoms...

OBJECTIVE: Recently, regenerative therapies have been used in clinical trials (heart, cartilage, skeletal). We don't make use of these treatments to spinal cord injury (SCI) patients yet, but regenerative therapies are rising interest in recent study about SCI. Neural precursor/stem cell (NPSC) proliferation is a significant event in functional recovery of the central nervous system (CNS). However, brain NPSCs and spinal cord NPSCs (SC-NPSCs) have many differences including gene expression and proliferation...
