Magnetic resonance imaging of arterial stroke mimics: a pictorial review
AbstractAcute ischaemic stroke represents the most common cause of new sudden neurological deficit, but other diseases mimicking stroke happen in about one-third of the cases. Magnetic resonance imaging (MRI) is the best technique to identify those ‘stroke mimics’. In this article, we propose a diagnostic approach of those stroke mimics on MRI according to an algorithm based on diffusion-weighted imaging (DWI), which can be abnormal or normal, followed by the results of other common additional MRI sequences, such as T2 with gradient recall ed echo weighted imaging (T2-GRE) and fluid-attenuated inversion recovery (FLAIR...

Association of Cytomegalovirus Infection with Lenticulostriate Stroke After Mild Head Trauma in Young Children
In this study, we explored the association of a recent viral infection with the development of infantile lenticulostriate stroke with lenticulostriate calcification following mild head trauma in children. We examined the records for 49 children (<36 months old) diagnosed with infantile stroke following mild head trauma at the First Hospital of Jilin University between January 2007 and August 2019. The demographic characteristics, clinical manifestations, and laboratory and imaging results were collected and analyzed. Antibodies against Epstein-Barr virus, herpes simplex virus, and cytomegalovirus in the patient sera wer...

Infectious Agents and Stroke: A Systematic Review
CONCLUSION: Considering the adverse role of the above-mentioned microorganisms, it is necessary to implement some preventive measures for stroke treatment.PMID:35154584 | PMC:PMC8817172 | DOI:10.32598/bcn.2021.1324.2

Herpesvirus Infections and Childhood Arterial Ischemic Stroke: Results of the VIPS Study.
CONCLUSIONS: -Herpesviruses may act as a trigger for childhood AIS, even if the infection is subclinical. Antivirals like acyclovir might have a role in the prevention of recurrent stroke if further studies confirm a causal relationship. PMID: 26813104 [PubMed - as supplied by publisher]

Late-onset Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-like Episodes Presenting With Auditory Agnosia
Conclusions: MELAS is a disorder with clinical variability. Neuroimaging studies during stroke-like episodes in MELAS can provide significant clues to the underlying disorder. Although patients typically present in childhood, the first stroke-like episode can occur later in life in some patients, potentially related to a lower heteroplasmy level.

Herpes simplex virus 2 vasculitis as cause of ischemic stroke in a young immunocompromised patient
We report a case of a young woman with a left middle cerebral artery (MCA) ischemic stroke. The patient had history of HIV-1 infection, with periods of therapeutic non-compliance. Initial computed tomography (CT) imaging studies showed stenosis of the M1 segment of the left MCA, and magnetic resonance imaging (MRI) confirmed infarction of the MCA territory. Serial transcranial Doppler ultrasound revealed progressive occlusion of the MCA and stenosis of the left anterior cerebral artery. Systemic investigation for other causes of stroke was normal. Lumbar puncture revealed a mildly inflammatory cerebrospinal fluid, and HSV-...

HSV-Encephalitis Resembling Acute Cerebral Infarction in a Patient With Atrial Fibrillation: Beware of Stroke Mimics
Conclusion: HSV-encephalitis might occasionally result in the development of unilateral brain MRI lesions with extensive cytotoxic edema, resembling an acute ischemic stroke. Therefore, HSV-encephalitis must be considered in the differential diagnosis of acute ischemic stroke with atypical presentation. The presence of a significant dissociation between the brain MRI lesion volume and the neurological deficits, as well as certain brain MRI imaging discrepancies might serve as “red flags” to extend the diagnostic workup.

GLUTAMATE RECEPTOR ANTIBODIES IN NEUROLOGICAL DISEASES: Anti-AMPA-GluR3 antibodies, Anti-NMDA-NR1 antibodies, Anti-NMDA-NR2A/B antibodies, Anti-mGluR1 antibodies or Anti-mGluR5 antibodies are present in subpopulations of patients with either: Epilepsy, Encephalitis, Cerebellar Ataxia, Systemic Lupus Erythematosus (SLE) and Neuropsychiatric SLE, Sjogren's syndrome, Schizophrenia, Mania or Stroke. These autoimmune anti-glutamate receptor antibodies can bind neurons in few brain regions, activate glutamate receptors, decrease glutamate receptor's expression, impair glutamate-induced signaling and function, activate Blood Brain Barrier endothelial cells, kill neurons, damage the brain, induce behavioral/psychiatric/cognitive abnormalities and Ataxia in animal models, and can be removed or silenced in some patients by immunotherapy.
Abstract Glutamate is the major excitatory neurotransmitter of the Central Nervous System (CNS), and it is crucially needed for numerous key neuronal functions. Yet, excess glutamate causes massive neuronal death and brain damage by excitotoxicity-detrimental over activation of glutamate receptors. Glutamate-mediated excitotoxicity is the main pathological process taking place in many types of acute and chronic CNS diseases and injuries. In recent years, it became clear that not only excess glutamate can cause massive brain damage, but that several types of anti-glutamate receptor antibodies, that are present in ...

Biological Plausibility of a Link Between Arterial Ischemic Stroke and Infection with Varicella-Zoster Virus or Herpes Simplex Virus.
Abstract There are now 9 human herpesviruses; the increase from 8 to 9 was caused by a recent decision to split human herpesvirus (HHV) strains 6A and 6B into distinct species. The 9 species are subdivided into three subfamilies, called alpha: herpes simplex virus (HSV) types 1 and 2 and varicella-zoster virus (VZV); beta: cytomegalovirus (CMV), HHV6A, HHV6B and HHV7; gamma: Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (sometimes called HHV8). These same herpesviruses have evolved with humankind around the world since the great migration of modern humans across the Mandeb Strait out of Afri...

Carotid intima media thickness and blood biomarkers of atherosclerosis in patients after stroke or myocardial infarction.
CONCLUSIONS: Our study supports linear correlations between CIMT and IC and hs-CRP levels. However, these associations seem to depend on the type of vascular burden. PMID: 28051279 [PubMed - in process]

Herpes Simplex Laryngitis Presenting as Airway Obstruction in a Stroke Patient
We present the second confirmed report of HSV laryngitis in an adult stroke patient, resulting in complicated airway management issues. This rare presentation of laryngeal HSV in a stroke patient can interfere with speech, language, and swallowing functions and confounds the etiology of these issues, which can impact subsequent management.

Herpes simplex virus encephalitis mimicking acute ischemic stroke
CONCLUSION: HSV infections may mimic stroke and therefore should be included in the differential diagnosis of atypical acute nervous conditions. In neurological events of acute nature, especially in febrile patients whose brain imaging is suspicious or inconclusive, the eventuality of a herpetic encephalitis should be kept in mind. This will lead to a prompt antiviral therapy and to a favorable outcome.PMID:36895212 | PMC:PMC9990771 | DOI:10.25259/SNI_1123_2022
