The prevalence of disability due to neurological conditions is escalating worldwide. Neurological disorders have significant disability-burden with long-term functional and psychosocial issues, requiring specialized rehabilitation services for comprehensive management, especially treatments tapping into brain recovery 'neuroplastic' processes. Neurorehabilitation is interdisciplinary and cross-sectorial, requiring coordinated effort of diverse sectors, professions, patients and community to manage complex condition-related disability...

BACKGROUND: Dimethyl fumarate (DMF), working via its metabolite monomethylfumarate (MMF), acts as a potent antioxidant and immunomodulator in animal models of neurologic disease and in patients with multiple sclerosis. These properties and their translational potential led us to investigate whether DMF/MMF could also protect at-risk and/or dying neurons in models of ischemic stroke in vitro and in vivo. Although the antioxidant effects have been partially addressed, the benefits of DMF immunomodulation after ischemic stroke still need to be explored...

INTRODUCTION: Neurological diseases are important co-morbidities found in association with bullous pemphigoid. Various neurological conditions (stroke, Parkinson's disease, dementia, epilepsy and multiple sclerosis) have been reported as associations of this bullous disease; whether these are significant has not been definitely proved. However, the presence of neurological conditions is a predictor of poorer prognosis. OBJECTIVES: Our aim was to examine the association of bullous pemphigoid and neurological diseases in Iranian bullous pemphigoid patients...

The blood-brain barrier (BBB) is indispensable for the maintenance of brain homeostasis and proper neuronal functioning. Dysfunction of the BBB significantly contributes to the pathogenesis of neuroinflammatory and neurodegenerative diseases like stroke, multiple sclerosis (MS), and Alzheimer's disease (AD). The neuroinflammatory environment that characterizes these disorders propagates chronic impaired function of the BBB, processes that will be discussed in this review. Limiting dysfunction of the BBB may be an attractive target for treatment of neurological disorders...

OBJECTIVES: Our primary aim was to validate the Patient Health Questionnaire (PHQ)-9 as a screening tool for suicidal ideation (SI). METHODS: Persons with epilepsy (n=188), migraine (n=208), multiple sclerosis (n=151), and stroke (n=122) completed questionnaires (e.g., PHQ-9) and the structured clinical interview for DSM-IV (SCID). Logistic regression was used to examine factors associated with SI [odds ratios (ORs) with 95% confidence intervals (CIs)]. The diagnostic accuracy of the PHQ-9 in identifying SI [sensitivity (Se), specificity (Sp), positive and negative predictive value (PPV and NPV)] was validated against the SCID...

Bullous pemphigoid (BP) is a chronic, autoimmune vesiculobullous disease that frequently occurs in the elderly population. Previous epidemiological studies have suggested an association between BP and neurological diseases; some studies, however, showed conflicting results. This study aimed to investigate if patients with BP have significantly higher risks for neurological disorders, compared to controls. A comprehensive search was performed using MEDLINE, EMBASE and Cochrane library databases. Case-control and cohort studies that assessed the relationship between BP and neurological diseases were included...

We provide an overview of rehabilitation in neurological diseases. A large amount of literature available on neurorehabilitation is based from the rehabilitative work on stroke and spinal cord injuries. After a brief description of rehabilitation, the potential application of neurorehabilitation in neurodegenerative diseases specifically multiple sclerosis (MS) is summarized. Since MS causes a wide variety of symptoms, the rehabilitation in MS patients may benefit from an interdisciplinary approach that encloses physiotherapy, cognitive rehabilitation, psychological therapy, occupational therapy, and other methods to improve fatigue...

KCa3.1 protein is part of a heterotetrameric voltage-independent potassium channel, the activity of which depends on the intracellular calcium binding to calmodulin. KCa3.1 is immensely significant in regulating immune responses and primarily expressed in cells of hematopoietic lineage. It is one of the attractive pharmacological targets that are known to inhibit neuroinflammation. KCa3.1 blockers mediate neuroprotection through multiple mechanisms, such as by targeting microglia-mediated neuronal killing. KCa3...

Activated protein C (APC) is a blood protease with anticoagulant activity and cell-signaling activities mediated by the activation of protease-activated receptor 1 (F2R, also known as PAR1) and F2RL1 (also known as PAR3) via noncanonical cleavage. Recombinant variants of APC, such as the 3K3A-APC (Lys191-193Ala) mutant in which three Lys residues (KKK191-193) were replaced with alanine, and/or its other mutants with reduced (>90%) anticoagulant activity, engineered to reduce APC-associated bleeding risk while retaining normal cell-signaling activity, have shown benefits in preclinical models of ischemic stroke, brain trauma, multiple sclerosis, amyotrophic lateral sclerosis, sepsis, ischemic and reperfusion injury of heart, kidney and liver, pulmonary, kidney and gastrointestinal inflammation, diabetes and lethal body radiation...

Protons are widespread in cells and serve a variety of important functions. In certain pathological conditions, acid-base balance was disrupted and therefore excessive protons were generated and accumulated, which is termed acidosis and proved toxic to the organism. In the nervous system, it has been reported that acidosis was a common phenomenon and contributed to neuronal injury in various kinds of neurological diseases, such as ischemic stroke, multiple sclerosis and Huntington's disease. Acid-sensing ion channels (ASICs) is the key receptor of protons and mediates acidosis-induced neuronal injury, but the underlying mechanism remains unclear...

Discovered in 1947, microparticles (MP) represent a group of sub-micron cell-derived particles isolated by high speed centrifugation. Once regarded as cellular 'trash', in the past decade MP have gained tremendous attention in both basic sciences and medical research both as biomarkers and mediators of infection, injury and response to therapy. Because MP bear cell surface markers derived from parent cells, accumulate in extracellular fluids (plasma, serum, milk, urine, cerebrospinal fluid) MP based tests are being developed commercially as important components in 'liquid biopsy' approaches, providing valuable readouts in cardiovascular disease and cancer, as well as stroke, Alzheimer's disease and Multiple Sclerosis...

: Neurological disorders account for a majority of non-malignant disability in humans and are often associated with dysfunction of the blood-brain barrier (BBB). Recent evidence shows that despite apparent variation in the origin of neural damage, the central nervous system has a common injury response mechanism involving platelet-derived growth factor (PDGF)-CC activation in the neurovascular unit and subsequent dysfunction of BBB integrity. Inhibition of PDGF-CC signaling with imatinib in mice has been shown to prevent BBB dysfunction and have neuroprotective effects in acute damage conditions, including traumatic brain injury, seizures or stroke, as well as in neurodegenerative diseases that develop over time, including multiple sclerosis and amyotrophic lateral sclerosis...

BACKGROUND: Fatigue is a common symptom following neurological illnesses and injuries, and is rated as one of the most debilitating sequela in conditions such as stroke, traumatic brain injury (TBI), and multiple sclerosis (MS). Yet effective treatments are lacking, suggesting a pressing need for a better understanding of its etiology and mechanisms that may alleviate the symptoms. Recently mindfulness-based interventions have demonstrated promising results for fatigue symptom relief...

The anatomic and physiologic changes that occur during pregnancy are unique. A neurologist needs to be aware of normal pregnancy-induced physiologic changes in the cardiovascular, renal, hematologic, and autoimmune systems, and the local anatomic changes, which include alteration of body habitus and pelvic ligaments. These changes are clearly advantageous, but in certain circumstances may predispose to pathology. In addition, pregnancy effects treatment of chronic neurologic conditions as regards medication safety and metabolism...
