Eight-and-a-half syndrome is one-and-a-half syndrome plus ipsilateral seventh (facial) cranial nerve palsy, which was first reported by Eggenberger in 1998. This syndrome is caused by a lesion (most often vascular or demyelinating) in the dorsal tegmentum of the caudal pons. It involves the para pontine reticular formation and the medial longitudinal fasciculus, as well as the nucleus and the fasciculus of the facial nerve. We describe a case of a 56-year-old man presented with eight-and-a-half syndrome. We also discuss the vascular pathology and etiology of this syndrome through the literature review. Most eight-and-a-half syndrome cases are caused by occlusions of the perforating branches of the pons. The pathology can be transparent lipid-like changes at the perforator arteries. It can also be thrombosis at the orifice of the main or perforator arteries. BAH could be a very important factor in perforator artery infarction at the pontine. The etiology is closely related to hyperglycemia. An effective intervention is to avoid bad habits and control the hyperglycemia.

Since the outbreak of the COVID-19 in Wuhan, China in 2019, there have been increasing reports of large vessel thrombosis and associated embolic stroke in patients with COVID-19 infection. The pathogenesis is thought to be multifactorial, including angiotensin-converting enzyme 2 receptor-mediated endothelial damage, rupture of atherosclerotic plaques, cytokine-storm induced-inflammation, and hypercoagulability. Here, we present a case of an otherwise-healthy COVID-19 patient who developed a right common carotid artery thrombus and embolic stroke with left sided numbness and weakness. Blood tests were significant for elevated levels of inflammatory biomarkers and di-dimer. Vessel imaging showed no evidence of underlying atherosclerosis or arterial dissection. Cardiac workup was unremarkable. The etiology of the carotid artery thrombus was likely COVID-19 related inflammation and hypercoagulability. He was started on apixaban 5mg twice daily for secondary stroke prevention. After 3 months, he was transitioned from apixaban to aspirin 81mg daily. At 4-month follow-up, he improved with only residual left arm numbness. Our case study suggests that in patients with large vessel thrombosis in the setting of Covid-19 infection, oral anticoagulation for 3 months followed by daily aspirin may be a reasonable treatment option for secondary stroke prevention.

Introduction: The term learning disabilities refers to a complex and multidimensional phenomenon that affects many thousands of students. Due to the rich symptomatology of learning difficulties and the increased differences between individuals, it has not been possible to analyze all cases exclusively from the perspective of the neuropsychological approach. Aim. The aim of this study was to present research conducted in the context of theories on the brain function of people with learning disabilities. Supporting the hypothesis of brain dysfunction. Methodology: Literature review was carried out in the web, which referred to researches on Special Learning Disabilities and the brain function associated with them. Results: Review of the literature highlighted key points of the relationship between learning difficulties and brain function. Brain dysfunction and the cognitive functions produced emerged as one of the key factors involved in learning disabilities. Many of the theories developed around the problems of children with learning disabilities have focused on specific areas of the brain that may be dysfunctional. Conclusions: The difficulty of locating obvious brain damage in individuals who have been characterized as dyslexic leads to the strengthening of the hypothesis of the existence of a slight or minimal brain damage that cannot be easily diagnosed and strengthens the hypothesis of an unexplained brain damage that could be heterogeneous groups of learning disabilities.

Autoimmune encephalitis (AE) is an important cause of seizures. With the discovery of highly specific neuronal-antibodies the recognition of the clinical syndrome associated with each marker is crucial to the right diagnosis and treatment regime. In this short review we summarize the importance of CASPR2 antibodies in unknown etiology seizures and its epileptogenesis.

Sigma receptors are widespread in the central nervous system and are differentiated in two subtypes, sigma1 and sigma2. In particular, the sigma1 receptor subtype appears to be able to influence biological mechanisms connected with neuro-degeneration. Furthermore, several studies are implicating sigma1 receptor agonists within antidepressant activity. Evidence of prefrontal cortex abnormalities in clinically depressed subjects have been reported by several works and that monoamines such as serotonin and cathecolamines can be involved in such malfunctions. Up to now the most of the preclinical work performed to analyze the influence of sigma1 receptor agonists upon catecholaminergic and serotoninergic activities in brain areas has been done by means of in vitro as well as ex vivo methodologies. Here, SA-4503, a selective sigma1 receptor agonist with potential antidepressant activity has been tested in vivo upon dopamine (DA), noradrenaline (NA) and serotonin (5-HT) levels detected by micro-dialysis in the medial Prefrontal Cortex (mPFC) of freely moving rats.

Introduction: Central nervous system tumors are rare; in 2015 they represented approximately 1.4% of new cancer diagnoses, causing 2.6% of deaths by cancer that year. In Colombia, there are few reports on the epidemiology of brain tumors, and those that exist are local databases that do not have a rigorous and massive registry. Due to limited epidemiological information in our country, this document aims to characterize the epidemiology of brain tumors in Colombia over a 10-year period. Methods: A retrospective descriptive observational study was conducted, using databases of population-based cancer registries in Colombia. We extracted information from a 10-year period recorded in patients with tumors without age group restriction. A descriptive analysis was carried out for all the variables considered, the incidence and mortality rates per 100,000 person years were calculated. Statistical software Stata 14.0 was used. Results: Our analysis was performed with a population of 775 adult patients and 123 pediatric patients, with an incidence of 1.55 per 100.000 individuals in the pediatric population and 3.19 per 100.000 individuals in the adult population. The mortality rate for pediatric and adult patients was 0.063 per 100.000 individuals and 1.86 per 100.000 individuals respectively. The most frequent tumors in the pediatric age group were neuroepithelial tumors, embryonal tumors and ependymal tumors, whereas for adults, the most frequent were neuroepithelial tumors, meningiomas and hematolymphoid tumors. Conclusions: This study constitutes the most recent work on the epidemiology of brain tumors in Colombia. There was a clear general underreporting and statistics lower than those compared with the literature. It is intended to expand coverage and data collection in population-based cancer registries.

Intradural disc herniation is a rare entity, representing between 0.26% and 0.30% of all herniated discs. 92% of cases occur in the lumbar spine, more frequent at the L4-L5 level. The diagnostic and therapeutic conduct performed in a 61-year-old male patient who came to the office with a one-year and six-month history of dorsolumbar pain is described, accompanied by sensory alterations in the lower limbs. In view of the exacerbation of symptoms, a simple magnetic resonance study was performed, observing an intraspinal, intradural, extramedullary lesion at the D12-L1 space. An intradural disc herniation is suspected. After being evaluated the case in the group of Neurosurgeons (Group of Spinal Surgery) of the Institute of Neurology and Neurosurgery of Havana, it is proposed to carry out surgical treatment, which consisted of the extraction with microsurgical technique of the Herniated disc, preserving the vertebral anatomy through the laminoplasty technique, an open book variant. The patient evolved satisfactorily after three months of follow-up. It is concluded that intradural disc herniation should be included among intradural, extraxial lesions of the spine. By means of the magnetic resonance study, a group of imaging signs that support the preoperative diagnosis of this lesion can be described. Surgery is the definitive therapeutic method and allows an accurate diagnosis of spinal herniation to be established.

BACKGROUND AND OBJECTIVE: This study examines the effect on third-grade students’ academic achievement and their pleasure and interest in lessons as a result of the incorporation of music into science classes. MATERIAL AND METHODS: Sixty third grade Arab school children were studied before and after listing a Mozart Concerto. Their pleasure and interest in the lesson was evaluated using the 20-statement Barak questionnaire. Comparison was made between an initial 6 lessons without music and subsequent 6 lessons with music. In another study at the Institute of Neurology and Neurosurgery in Havana, Cuba, continuous electroencephalographic monitoring (CEEG) was performed in 15 third-grade school children during 10 minutes at basal condition and for 10 minutes while listening to the same piece of music. RESULTS: Assessment scores in the science examination were significantly higher overall after listening to music. A clear increment of alpha and gamma absolute powers was found when listening to music, although for the alpha band this augmentation was significantly greater. An increment of the alpha band power was related to significantly better performance of spatial–temporal tasks when listening to music. Changes in the gamma frequency band represent cognitive processes. Hence, CEEG analysis adds to evidence that listening to music can increase enjoyment and improve academic achievement among elementary school students. CONCLUSION: We propose that music stimulates the formation of neural networks that prime the brain for learning. We recommend that teachers of core subjects, especially mathematics, science and languages, begin their lessons with 5 minutes of calm music.
