Restless legs syndrome related to hemorrhage of a thoracic spinal cord cavernoma.
CONCLUSION/CLINICAL RELEVANCE: We hypothesize a possible involvement of the diencephalospinal pathway in the patient's RLS pathophysiology. A systematic study of focal lesions associated with RLS may contribute to improving our understanding of the pathophysiological mechanisms underlying this condition. The frequency of RLS associated with lesions of the spinal cord might be underestimated. Clinicians should be aware of spinal cord lesion-related RLS, especially as efficient treatments are available. PMID: 28899286 [PubMed - as supplied by publisher]

Prevalence and Natural History of Superficial Siderosis Clinical Sciences
This study aimed to report the prevalence and natural history of SS in a population-based study.Methods—Brain magnetic resonance imaging scans from the MCSA (Mayo Clinic Study of Aging), a population-based study of residents 50 to 89 years of age in Olmsted County, Minnesota, were reviewed. Participants with imaging consistent with SS were identified from 2011 through 2016. An inverse probability weighting approach was used to convert our observed frequencies to population prevalence of SS. Additional data abstracted included amyloid positron emission tomography, Apolipoprotein E genotype, coexisting cerebral microbleeds...

Carotid Atheroma From Men Has Significantly Higher Levels of Inflammation and Iron Metabolism Enabled by Macrophages Clinical Sciences
Conclusions—Male patients with carotid atheroma had more advanced and ruptured lesions associated with significantly higher levels of inflammatory macrophage infiltration and high iron stores in the blood and in their plaques. These findings help to understand sex differences and iron metabolism in atherosclerosis and factors related to atheroma progression.

Minocycline Effects on Intracerebral Hemorrhage-Induced Iron Overload in Aged Rats Basic Sciences
This study quantified brain iron levels after ICH with magnetic resonance imaging R2* mapping. The effect of minocycline on iron overload and ICH-induced brain injury in aged rats was also determined.Methods—Aged (18 months old) male Fischer 344 rats had an intracerebral injection of autologous blood or saline, and brain iron levels were measured by magnetic resonance imaging R2* mapping. Some ICH rats were treated with minocycline or vehicle. The rats were euthanized at days 7 and 28 after ICH, and brains were used for immunohistochemistry and Western blot analyses. Magnetic resonance imaging (T2-weighted, T2* gradient-...

Minocycline attenuates brain injury and iron overload after intracerebral hemorrhage in aged female rats.
Abstract Brain iron overload is involved in brain injury after intracerebral hemorrhage (ICH). There is evidence that systemic administration of minocycline reduces brain iron level and improves neurological outcome in experimental models of hemorrhagic and ischemic stroke. However, there is evidence in cerebral ischemia that minocycline is not protective in aged female animals. Since most ICH research has used male models, this study was designed to provide an overall view of ICH-induced iron deposits at different time points (1 to 28 days) in aged (18-month old) female Fischer 344 rat ICH model and to investig...

Molecular Magnetic Resonance Imaging of Endothelial Activation in the Central Nervous System
Endothelial cells of the central nervous system over-express surface proteins during neurological disorders, either as a cause, or a consequence, of the disease. Since the cerebral vasculature is easily accessible by large contrast-carrying particles, it constitutes a target of choice for molecular magnetic resonance imaging (MRI). In this review, we highlight the most recent advances in molecular MRI of brain endothelial activation and focus on the development of micro-sized particles of iron oxide (MPIO) targeting adhesion molecules including intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (...

Ferroptosis, a Recent Defined Form of Critical Cell Death in Neurological Disorders
AbstractFerroptosis is a recently defined form of cell death with the involvement of iron and reactive oxygen species (ROS), which is distinct from apoptosis, autophagy and other forms of cell death. Emerging evidence suggested that iron accumulation and lipid peroxidation can be discovered in various neurological diseases, accompanied with reduction of glutathione (GSH) and glutathione peroxidase 4 (GPX4). In addition, ferroptotic inhibitors have been shown to protect neurons, and recover the cognitive function in disease animal models. This review summarizes the mechanisms underlying ferroptosis and reviews the contribut...

Edaravone Reduces Iron-Mediated Hydrocephalus and Behavioral Disorder in Rat by Activating the Nrf2/HO-1 Pathway
Our previous studies have demonstrated that hemorrhage-derived iron has a key role in causing brain injury after intraventricular hemorrhage (IVH). Based on this finding, we hypothesized that edaravone, a free-radical scavenger, has the potential to alleviate hydrocephalus and neurological deficits post-IVH by suppressing iron-induced oxidative stress. Thus, this study aimed to investigate the efficacy of edaravone for rats with FeCl3 injection, as well as to explore the related molecular mechanism.

Brain Ceruloplasmin Expression After Experimental Intracerebral Hemorrhage and Protection Against Iron-Induced Brain Injury
This study had two parts: first, rats had injection of autologous blood into the right basal ganglia and the time course of CP expression in the brain examined (protein and mRNA). Second, rats had an injection of either Fe2+ in saline, Fe2+ plus CP in saline, or saline alone into the right basal ganglia. All rats in the second part had T2-weighted magnetic resonance imaging, and behavioral tests before the brains were harvested for immunohistochemistry and Western blotting. We found that CP was expressed on neurons and astrocytes in both cortex and basal ganglia after ICH. The time course showed that ICH induced CP express...

Ferroptosis and Brain Injury
Ferroptosis is a nonapoptotic form of cell death characterized by the iron-dependent accumulation of toxic lipid reactive oxygen species. Small-molecule screening and subsequent optimization have yielded potent and specific activators and inhibitors of this process. These compounds have been employed to dissect the lethal mechanism and implicate this process in pathological cell death events observed in many tissues, including the brain. Indeed, ferroptosis is emerging as an important mechanism of cell death during stroke, intracerebral hemorrhage, and other acute brain injuries, and may also play a role in certain degener...

Overview of Pulmonary Arteriovenous Malformations and Hereditary Hemorrhagic Telangiectasia
Pulmonary arteriovenous malformations (PAVMs) are rare and commonly caused by an autosomal dominant disorder known as hereditary hemorrhagic telangiectasia (HHT). HHT is an often-missed vascular disorder causing symptoms of epistaxis, mucosal telangiectasia, AVMs, hemoptysis, dyspnea, and iron deficiency anemia. Large AVMs in the lungs, liver, and brain can be life-threatening. Early diagnosis and intervention are imperative to prevent serious complications of massive hemoptysis, stroke, cerebral abscess, and gastrointestinal bleeding.
