INTRODUCTION: Wernicke encephalopathy (WE) is a potentially fatal condition caused by thiamine (vitamin B1) deficiency. Chronic alcoholism is the most common cause of WE; however, other conditions responsible for thiamine deficiency should also be considered. CASE REPORT: We report the case of a 64-year-old woman with a history of diabetes who presented with confusion and apathy. Magnetic resonance imaging of the brain showed T2 hyperintensities involving dorsolateral medulla oblongata, tegmentum of the pons, vermis of the cerebellum, periaqueductal region, and the bilateral mammillary bodies...

BACKGROUND: Wernicke's encephalopathy (WE) is an acute neurological syndrome resulting from thiamine (vitamin B1) deficiency. It has been recognized increasingly in non-alcoholic patients, such as in the condition of malnutrition. Recent literature has shed light on uncommon symptoms and neuroimaging findings. CASE REPORT: We reported a case of a 44-year-old male who initially presented with bilateral hearing loss, and exhibited abnormality in the splenium of the corpus callosum on magnetic resonance imaging (MRI) diffusion-weighted imaging sequence...

(1) Background: In hereditary creatine transporter deficiency (CTD), there is an absence of creatine in the brain and neurological symptoms are present, including severe language impairment. However, the pathological changes caused by creatine deficiency that generate neuropsychological symptoms have been poorly studied. (2) Aims: To investigate if the language impairment in CTD is underpinned by possible pathological changes. (3) Methods: We used MRI tractography to investigate the trophism of the left arcuate fasciculus, a white matter bundle connecting Wernicke's and Broca's language areas that is specifically relevant for language establishment and maintenance, in two patients (28 and 18 y...

We describe a case of Neuromyelitis Optica Spectrum Disorder (NMOSD) mimicking Wernicke's Encephalopathy (WE) to highlight an atypical presentation of NMOSD. A 39-year-old female presented with subacute encephalopathy and progressive ophthalmoplegia. Her MRI revealed T2 hyperintensities involving the mammillary bodies, periaqueductal grey matter, medial thalami, third ventricle, and area postrema. Whole blood thiamine levels were elevated and she did not improve with IV thiamine. CSF was notable for lymphocytic pleocytosis and elevated protein...

Wernicke encephalopathy (WE) is a seldom encountered yet significant neuropsychiatric ailment resulting from a deficiency in thiamine (vitamin B1). While commonly linked with chronic alcoholism or insufficient dietary intake, instances of WE following bariatric and metabolic surgeries, notably laparoscopic Roux-en-Y gastric bypass (RYGB), have been sporadically documented. This case study elucidates the condition of a male patient who, 3 months after undergoing RYGB to address severe obesity, displayed abrupt alterations in mental status, swiftly ameliorated by immediate administration of intravenous high-dose thiamine...

BACKGROUND: Gastrointestinal Stromal Tumors (GISTs) are the most common mesenchymal tumors of the GI tract. SEER is an extensive cancer database which proves useful in analyzing population trends. This analysis investigated GIST outcomes between geriatric & non-geriatric patients. METHODS: SEER*STAT 8.4.0.1 was used to extract relevant GIST data from 2000 to 2019. Geriatric age was defined as ≥70 years. Variables included age, sex, surgery, cancer-specific death, and overall survival...

Chromatin architecture regulates gene expression and shapes cellular identity, particularly in neuronal cells. Specifically, polycomb group (PcG) proteins enable establishment and maintenance of neuronal cell type by reorganizing chromatin into repressive domains that limit the expression of fate-determining genes and sustain distinct gene expression patterns in neurons. Here, we map the 3D genome architecture in neuronal and non-neuronal cells isolated from the Wernicke's area of four human brains and comprehensively analyze neuron-specific aspects of chromatin organization...

[Objective] To investigate association between Wernicke encephalopathy (WE) and brain MRI. [Subjects] 26 patients (7 females, mean age 63.9 ± 12.7 years) with WE admitted to our department between May 2008 and September 2022. [Methods] Wernicke's encephalopathy in patients with MRI lesions was defined as "MRI-positive group" (MPG), and those without MRI lesions as "MRI-negative group" (MNG). The following parameters were assessed between the two groups: age, sex, alcoholism, neurological symptoms, vitamin B1 , lymphocyte, total cholesterol, albumin, and outcome at discharge...

Childhood poverty is related to deficits in multiple cognitive domains including adult language function. It is unknown if the brain basis of language is disrupted in adults with childhood poverty backgrounds, controlling for current functioning. Fifty-one adults (age 24) from an existing longitudinal study of childhood poverty, beginning at age 9, were examined on behavioral phonological awareness (LP) and completed an event-related fMRI speech/print processing LP task. Adults from childhood poverty backgrounds exhibited lower LP in adulthood...

"The history of the world is the biography of the great man. And I said: the great man always acts like a thunder. He storms the skies, while others are waiting to be stormed," said Thomas Carlyle. In this historical vignette, we study the contribution to neuroanatomy, of greats from the past. What led them to find the basis of topography and anatomical localization? How did they unravel the pathways of cerebrospinal fluid and cortical structure of the human brain? To understand this, we study the paths of Pierre Paul Broca, Richard L...

BACKGROUND: Chronic heavy alcohol use may lead to permanent brain damage, cognitive impairment, and dementia. While the link between alcohol use and crime is strong, virtually no research exists on the criminal behavior of patients with the alcohol-related neurocognitive disorders of Wernicke-Korsakoff syndrome (WKS) and alcohol-related dementia (ARD). METHODS: The study population included all persons diagnosed with WKS (n = 1149) or ARD (n = 2432) in Finland in 1998-2015...

We assessed the effect of a dietary pattern rich in unsaturated fatty acids (UFA), protein and fibers, without emphasizing energy restriction, on visceral adipose tissue (VAT) and cardiometabolic risk profile. Within the 36-months randomized controlled NutriAct trial, we randomly assigned 502 participants (50-80 years) to an intervention or control group (IG, CG). The dietary pattern of the IG includes high intake of mono-/polyunsaturated fatty acids (MUFA/PUFA 15-20% E/10-15% E), predominantly plant protein (15-25% E) and fiber (≥30 g/day)...

INTRODUCTION: Dural arteriovenous fistula (DAVF) is an uncommon malformation involving an abnormal connection between dural arteries, or the pachymeningeal branches of cerebral arteries, and dural veins. Its exact pathogenesis remains elusive. Known potential triggers for DAVF include cerebral venous sinus thrombosis (CVST), trauma, ear infections, and cranial surgeries. Due to its rarity and diverse clinical presentations, diagnosing DAVF can be a challenge. CASE DESCRIPTION: We present a case of DAVF associated with CVST, manifesting as rapidly advancing parkinsonism accompanied by dementia over a month...

Wernicke (Der aphasische Symptomencomplex: Eine psychologische Studie auf anatomischer Basis. Cohn und Weigert, Breslau.  https://wellcomecollection.org/works/dwv5w9rw , 1874) proposed a model of the functional neuroanatomy of spoken word repetition, production, and comprehension. At the heart of this epoch-making model are psychological reflex arcs underpinned by fiber tracts connecting sensory to motor areas. Here, I evaluate the central assumption of psychological reflex arcs in light of what we have learned about language in the brain during the past 150 years...

BACKGROUND: Alcohol use has an effect on nutritional status, with nutritional deficiencies being a major contributor to morbidity, for example Wernicke's encephalopathy. Currently, there is an absence of best-practice guidelines to support general practitioners (GPs) in the identification and management of malnutrition and nutritional risk factors in patients who drink at risky levels. OBJECTIVE: This article reviews some of the nutritional considerations in patients who drink at risky levels or who have alcohol dependence, with the aim of enhancing GPs' awareness of the nutritional considerations in this patient group...

BACKGROUND: Thiamine deficiency disease may occur in infants from thiamine-deficient mothers in developing countries, as well as in infants fed solely with soy-based formula. Thiamine deficiency in infants may present with acute neurological manifestations of infantile encephalitic beriberi. OBJECTIVE: To review the role of noncontrast CT brain findings in infantile encephalitic beriberi in early diagnosis. MATERIALS AND METHODS: A retrospective review of noncontrast CT scans of the brain in 21 infants with acute-onset infantile encephalitic beriberi was carried out...

Wernicke encephalopathy, which is caused by a thiamine deficiency, occurs in 0.8-2% of the population. Only 16% present the typical triad of this disease: nystagmus, confusion and ataxia. We present the case of a postoperative patient with a one anastomosis gastric bypass with reoperation undergoing a Roux-en-Y gastric bypass that begins with confusion and nystagmus on her third postoperative day. The diagnosis of Wernicke encephalopathy is made by imaging, and vitamin B1 is administered with total improvement of nystagmus and altered state of consciousness (lethargy, bradypsychia, bradylalia)...

Hyperemesis gravidarum is the most common condition requiring hospital care for women during the first 20 weeks of pregnancy and may lead to malnutrition, dehydration, and vitamin deficiencies. Depletion of vitamins such as thiamine may result in the development of Wernicke encephalopathy, a severe neurological disorder that can increase the risk for mortality and morbidity for the mother and fetus. A lack of awareness regarding the relationship of hyperemesis gravidarum and Wernicke encephalopathy may result in delayed treatment and disease management...

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by a lack of behavioral flexibility and stereotyped language. Food selectivity is common among children with ASD because of their persnickety nature. A prolonged unbalanced diet results in an increased risk of several diseases, such as iron deficiency anemia, scurvy, rickets, dry eye, and Wernicke encephalopathy. However, no cases of megaloblastic anemia have been reported to date. We report the case of an 11-year-old boy with ASD who developed megaloblastic anemia due to vitamin B12 deficiency...
