Tissue Sodium Concentration within White Matter Correlates with the Extent of Small Vessel Disease
Conclusion: The significant difference in absolute TSC in WM in patients with severe small vessel disease; Fazekas grade 3 can lead to inaccuracies using rTSC quantification for evaluation of acute ischemic stroke using23 Na MRI. The study, therefore, emphasizes the importance of absolute tissue sodium quantification.Cerebrovasc Dis

The Frontal Aslant Tract: A Systematic Review for Neurosurgical Applications
The frontal aslant tract (FAT) is a recently identified white matter tract connecting the supplementary motor complex and lateral superior frontal gyrus to the inferior frontal gyrus. Advancements in neuroimaging and refinements to anatomical dissection techniques of the human brain white matter contributed to the recent description of the FAT anatomical and functional connectivity and its role in the pathogenesis of several neurological, psychiatric, and neurosurgical disorders. Through the application of diffusion tractography and intraoperative electrical brain stimulation, the FAT was shown to have a role in speech and...

Serum Level of Transferrin Unique Peptide Is Decreased in Patients With Acute Ischemic Stroke
Conclusions: Serum TF-UP/LRP level is decreased in patients with acute ischemic stroke in comparison with brain tumor, and it may serve as a serum biomarker for the neuronal/glial cell damage in cerebral infarction.

Ipsilesional spatial bias after a focal cerebral infarction in the medial agranular cortex: A mouse model of unilateral spatial neglect.
In this study, a mouse model of unilateral spatial neglect was created to investigate whether the size of the lesion is related to the severity of ipsilesional spatial bias and the recovery process. Focal infarction was induced in the right medial agranular cortex (AGm) of mice via photothrombosis. After induction of cerebral infarction, ipsilesional spatial bias was evaluated for 9 consecutive days. The major findings were as follows: (1) unilateral local infarction of the AGm resulted in ipsilateral bias during internally guided decision-making; (2) the lesion size was correlated with the degree of impairment rather than...

Integrated Discourse Therapy After Glioblastoma: A Case Report of Face-To-Face and Tele-NeuroRehabilitation Treatment Delivery
Conclusions: This study provides preliminary support for F2F and TNR delivery of ICT discourse intervention for glioblastoma survivors. It also highlights the need for more research specifically dedicated to language therapy for this population.

Visual Mapping With Magnetoencephalography: An Update on the Current State of Clinical Research and Practice With Considerations for Clinical Practice Guidelines
Summary: Using visual evoked fields (VEFs) to differentiate healthy, normal brain function from dysfunctional cortex has been demonstrated to be both valid and reliable. Currently, VEFs are widely implemented to guide intracranial surgeries for epilepsy and brain tumors. There are several areas of possible future clinical use of VEFs, including early identification of disorders, such as multiple sclerosis, Parkinson's disease, stroke, and human immunodeficiency virus–associated neurocognitive disorders. These studies have suggested that VEFs could be used to study disease pathophysiology or as a biomarker for early i...

Cerebral Autoregulation and Neurovascular Coupling after Craniospinal Irradiation in Long-Term Survivors of Malignant Pediatric Brain Tumors of the Posterior Fossa
Conclusion In this pilot study, we demonstrated a trend toward reduced cerebral autoregulation, and no alteration of neurovascular coupling after irradiation in long-term survivors of malignant pediatric brain tumors of the posterior fossa.

Stroke-like migraine attacks after radiation therapy (SMART) syndrome —a case series and review
ConclusionOur extensive review favors MRI, CT, and prolonged EEG monitoring to rule out other differentials and showed that initiation of corticosteroid therapy and antiepileptic treatment were helpful in the resolution of symptoms and prevent recurrences. Therefore, future studies should be focused on early identification and management guidelines for SMART syndrome.

Social Cognition and White Matter: Connectivity and Cooperation
Humans are highly social animals whose survival and well-being depend on their capacity to cooperate in complex social settings. Advances in anthropology and psychology have demonstrated the importance of cooperation for enhancing social cohesion and minimizing conflict. The understanding of social behavior is informed by the notion of social cognition, a set of mental operations including emotion perception, mentalizing, and empathy. The social brain hypothesis posits that the mammalian brain has enlarged over evolution to meet the challenges of social life, culminating in a large human brain well adapted for social cogni...

A Single-Scan, Rapid Whole-Brain Protocol for Quantitative Water Content Mapping With Neurobiological Implications
Water concentration is tightly regulated in the healthy human brain and changes only slightly with age and gender in healthy subjects. Consequently, changes in water content are important for the characterization of disease. MRI can be used to measure changes in brain water content, but as these changes are usually in the low percentage range, highly accurate and precise methods are required for detection. The method proposed here is based on a long-TR (10 s) multiple-echo gradient-echo measurement with an acquisition time of 7:21 min. Using such a long TR ensures that there is no T1 weighting, meaning that the image inten...

New-onset refractory status epilepticus: a retrospective cohort study
Status epilepticus (SE) is a neurological emergency with more than 180 described causes; common causes include medication change or noncompliance in patients with known epilepsy, toxic-metabolic disturbances, sedative/hypnotic withdrawal, acute/remote stroke, and brain tumor [1]. The term new-onset refractory SE (NORSE) is applied to a patient without a prior diagnosis of epilepsy or other preexisting relevant neurological disorder, with new onset of refractory SE (RSE) that does not respond to first- and second-line antiseizure drugs and no clear acute or active structural, toxic, or metabolic cause.

Predictors of Class I epilepsy surgery outcome in tumour-related chronic temporal lobe epilepsy in adults.
CONCLUSION: The most appropriate management of tumour-related chronic temporal lobe epilepsy in adults appears to be tai-lored temporal lobe resection including tumour and hippocampal complex removal. Surgical treatment of tumoural temporal lobe epilepsy demonstrates excellent results in terms of seizure improvement, especially in patients with glioneuronal tumours.

Effects of early postnatal exposure to fine particulate matter on emotional and cognitive development and structural synaptic plasticity in immature and mature rats
ConclusionsOur findings indicate that PM2.5 impairs emotional and cognitive development by disrupting structural synaptic plasticity, possibly via the CREB/BDNF signaling pathway.

Relationship between androgenic alopecia and white matter hyperintensities in apparently healthy subjects
AbstractA healthy brain is essential for living a longer and fuller life. Detecting asymptomatic white matter hyperintensities (WMHs) may be clinically important in terms of treatment and prognostic evaluation. WMHs in brain may reflect brain aging. Androgenic alopecia (AGA) is associated with significant cardiovascular risk factors that also have a negative impact on brain aging. The main purpose of present study was to know whether alopecia might provide predictive information of WMHs that may be considered as a surrogate marker of cerebral small vessel disease which is related to arteriolosclerosis and vascular risk fac...
