Arterial spin labeling (ASL) is a magnetic resonance (MR) imaging technique used to assess cerebral blood flow noninvasively by magnetically labeling inflowing blood. In this article, the main labeling techniques, notably pulsed and pseudocontinuous ASL, as well as emerging clinical applications will be reviewed. In dementia, the pattern of hypoperfusion on ASL images closely matches the established patterns of hypometabolism on fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) images due to the close coupling of perfusion and metabolism in the brain...

Gastrodin (GAS), which is extracted from the Chinese herbal medicine Gastrodia elata Blume, has long been used to improve stroke, epilepsy, dizziness and dementia. However, the effects and underlying mechanisms of GAS on subacute phase cerebral ischemia‑reperfusion (I/R) injury remain unknown. The aim of the present study was to investigate the effects and mechanisms of GAS on cerebral I/R injury in rats. The rats were pretreated with GAS by gavage for 7 days followed by I/R surgery, and were then treated with GAS for 7 days after I/R surgery...

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...

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...

A screening questionnaire is an important tool for early diagnosis of neurological disorders, and for epidemiological research. This screening instrument must be both feasible and valid. It must be accepted by the community and must be sensitive enough. So, the aim of this study was to prepare different Arabic screening questionnaires for screening different neurological disorders. This study was carried out in three stages. During the first stage, construction of separate questionnaires designed for screening the five major neurological disorders: cerebrovascular stroke, dementias, epilepsy, movement disorders, and muscle and neuromuscular disorders were done...

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...

Several studies have highlighted the therapeutic potential of transcranial direct current stimulation (tDCS) in patients with neurological diseases, including dementia, epilepsy, post-stroke dysfunctions, movement disorders, and other pathological conditions. Because of this technique's ability to modify cerebellar excitability without significant side effects, cerebellar tDCS is a new, interesting, and powerful tool to induce plastic modifications in the cerebellum. In this report, we review a number of interesting studies on the application of cerebellar tDCS for various neurological conditions (ataxia, Parkinson's disease, dystonia, essential tremor) and the possible mechanism by which the stimulation acts on the cerebellum...

Post-stroke epilepsy (PSE) is defined as "recurrent seizures following stroke with confirmed diagnosis of epilepsy". Our objective was to describe the epidemiological, clinical and therapeutic PSE aspects at the Yalgado Ouedraogo Teaching Hospital, the main reference centre for neurological conditions in Burkina Faso. We conducted a retrospective study from January 2006 to December 2014. The data on thirty-two (32) cases of PSE was collected from a total of 1616 patients hospitalized for stroke, representing a rate of 1...

Mitochondrial diseases (MIDs) are a large group of heterogeneous disorders due to mutations in either mitochondrial DNA (mtDNA) or nuclear DNA (nDNA) genes, the latter encoding proteins involved in mitochondrial function. A multisystem clinical picture that involves several organs, including both the peripheral and central nervous systems, is a common presentation of MID. Movement disorders, even isolated ones, are not rare. Cerebellar ataxia is common in myoclonic epilepsy with ragged red fibers (MERFF) due to mutations in the mitochondrial transfer RNA (tRNA) lysine gene, in Kearns-Sayre syndrome due to mtDNA deletions, in sensory ataxic neuropathy with dysarthria and ophthalmoplegia (SANDO) due to nuclear POLG1 gene mutations, and also in ARCA2, Friedreich's ataxia, SPG7, SCA28 and autosomal-recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) due to mutations in nuclear genes involved in mitochondrial morphology or function...

BACKGROUND: Neurological disorders are heterogeneous clinical conditions with variable course and outcome. SUMMARY: The basic aspects of the commonest neurological disorders are addressed along with the proposed structure of randomized clinical trials (RCTs). Dementing disorders, including Alzheimer's disease (AD), are clinical conditions in which altered cognitive functions are associated with behavioral and personality changes. Parkinson's disease (PD) is a multisystem disorder characterized by motor dysfunction associated with dysautonomia, sleep and olfactory disturbances, cognitive changes, and depression...

This Review describes the current status of poststroke epilepsy (PSE) with an emphasis on poststroke epileptogenesis modeling for testing new therapeutic agents. Stroke is a leading cause of epilepsy in an aging population. Late-onset "epileptic" seizures have been reported in up to 30% cases after stroke. Nevertheless, the overall prevalence of PSE is 2-4%. Rodent models of stroke have contributed to our understanding of the relationship between seizures and the underlying ischemic damage to neurons. To understand whether acutely generated stroke events lead to a chronic phenotype more closely resembling PSE with recurrent seizures, a limited variety of approaches emerged in early 2000s...

Death-associated protein kinase 1 (DAPK1), a Ca(2+)/calmodulin (CaM)-dependent serine/threonine protein kinase, plays important roles in diverse apoptosis pathways not only in tumor suppression but also in neuronal cell death. The requirement of DAPK1 catalytic activity for its proposed cell functions and the elevation of catalytic activity of DAPK1 in injured neurons in models of neurological diseases, such as ischemia and epilepsy, validate that DAPK1 can be taken as a potential therapeutic target in these diseases...

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...

Pediatric neurology relies on ultrasound, computed tomography (CT), and magnetic resonance (MR) imaging. CT prevails in acute neurologic presentations, including traumatic brain injury (TBI), nontraumatic coma, stroke, and status epilepticus, because of easy availability, with images of diagnostic quality, e.g., to exclude hemorrhage, usually completed quickly enough to avoid sedation. Concerns over the risks of ionizing radiation mean re-imaging and higher-dose procedures, e.g., arteriography and venography, require justification...

OBJECTIVE: Seizures may occur in close temporal association with a stroke or after a variable interval. Moreover, epilepsy is often encountered in patients with leukoaraiosis. Although early post-stroke seizures have been studied extensively, less attention has been paid to post-stroke epilepsy (PSE) and to epilepsy associated with leukoaraiosis (EAL). The aim of this paper is to review data concerning pathophysiology, prognosis, and treatment of PSE and EAL. METHODS: We performed an extensive literature search to identify experimental and clinical articles on PSE and EAL...
