Chronic alcohol use induces silent changes in the structure and function of the central and peripheral nervous systems that eventually result in irreversible, debilitating repercussions. Once identified, nutritional supplementation and cessation measures are critical in preventing further neurologic damage. The proposed mechanisms of neuronal injury in chronic alcohol abuse include direct toxic effects of alcohol and indirect effects, including those resulting from hepatic dysfunction, nutritional deficiencies, and neuroinflammation.

An 83-year-old Japanese man presented with gait disturbance followed by rapidly-progressive cognitive impairment. Magnetic resonance diffusion-weighted images showed extensive hyperintense regions in the cerebral cortex. Four weeks after symptom onset, myoclonus appeared, and the patient developed difficulty swallowing; intravenous peripheral continuous infusions without vitamin supplementation were administered during the last two months of the patient's life.

This case discusses the course of a woman with a history of epilepsy, alcohol use disorder, herpes simplex virus (HSV) encephalitis, and Wernicke encephalopathy (WE) who presented with altered mental status following approximately 48 hours of vomiting. After experiencing a tonic-clonic seizure in the emergency department, she developed a fluent aphasia. Aphasias are ordinarily attributed to structural changes in the brain parenchyma, often from stroke, neoplasm, or infection. Read More

Objective: To explain (1) why an initial upbeat nystagmus (UBN) converts to a permanent downbeat nystagmus (DBN) in Wernicke encephalopathy (WE) and (2) why convergence and certain vestibular provocative maneuvers may transiently switch UBN to DBN.

Methods: Following a literature review and study of our 2 patients, we develop hypotheses for the unusual patterns of vertical nystagmus in WE.

Results: Our overarching hypothesis is that there is a selective vulnerability and a selective recovery from thiamine deficiency of neurons within brainstem gaze-holding networks. Read More

Wernicke encephalopathy (WE) and Korsakoff psychosis (KP), together termed Wernicke-Korsakoff syndrome (WKS), are distinct yet overlapping neuropsychiatric disorders associated with thiamine deficiency. Thiamine pyrophosphate, the biologically active form of thiamine, is essential for multiple biochemical pathways involved in carbohydrate utilization. Both genetic susceptibilities and acquired deficiencies as a result of alcoholic and non-alcoholic factors are associated with thiamine deficiency or its impaired utilization. Read More

Wernicke's encephalopathy (WE) is a life-threatening acute or sub-acute neurological emergency characterized by ataxia, confusion, nystagmus, and ophthalmoparesis caused by thiamine deficiency. It was first described in 1881 by Carl Wernicke with alcohol being the most common cause. We present a rare case of a 35-year-old pregnant female who presented to our emergency department with a history of vomiting and loose motions for two weeks. Read More

Objective: Although thiamine deficiency (TD) and Wernicke encephalopathy (WE) are not rare in cancer patients, the cases reported to date developed TD and/or WE after treatment had started.

Method: From a series of cancer patients, we report a patient diagnosed with TD without the typical clinical symptoms of WE at the preoperative psychiatric examination.ResultA 43-year-old woman with ovarian cancer was referred by her oncologist to the psycho-oncology outpatient clinic for preoperative psychiatric evaluation.

Progressive supranuclear palsy (PSP) may be a risk factor for thiamine deficiency. The classic symptoms of PSP (postural instability, supranuclear vertical gaze palsy and dementia) overlap with the clinical triad of Wernicke's encephalopathy (cognitive impairment, gait problems and ocular abnormality). Therefore, superimposed thiamine deficiency in patients with PSP may aggravate the pre-existing symptoms of PSP. Read More

Wernicke's encephalopathy (WE) is a rare neurological syndrome that presents in the setting of thiamine deficiency. Though alcoholism is the most common cause of this condition, a few other etiologies include malnutrition from other causes, hemodialysis, and hyperemesis gravidarum. In this case report, we aim to report a case of a young woman who developed WE in the setting of hyperemesis gravidarum (HG) that improved with thiamine replacement. Read More

The nervous system is vulnerable to intrinsic and extrinsic metabolic perturbations. In particular, the cerebellum, with its large Purkinje cells and its high density of neurons and glial cells, has high metabolic demand and is highly vulnerable to metabolic derangements. As a result, many disorders of intermediary metabolism will preferentially and sometimes selectively target the cerebellum. Read More

Bilateral vestibulopathy (BVP), which is due to peripheral lesions, may selectively involve certain semicircular canal (SCC). Recent eye movement recordings with search coil and video head impulse test (HIT) have provided insight in central lesions that can cause bilateral and selective SCC deficit mimicking BVP. Since neurological signs or ocular motor deficits maybe subtle or absent, it is critical to recognize central lesions correctly since there is prognostic and treatment implication. Read More

Background: Drinking more than the recommended limits is a worldwide emerging problem, difficult to circumscribe, and alcohol-related brain damages are an under-recognized health problem. Alcohol-cognitive disruption can be considered as transient and recoverable if the alcohol consumption is limited and occasional; if not, it can progress to the so-called Alcohol-Related Dementia (ARD), or to the Wernicke encephalopathy, or it can even induce the Korsakoff syndrome, an irreversible and long-lasting medical condition. ARD still remains poorly diagnosed and addressed, despite having increased research interest being a frustrating condition, a relatively non-progressive, or even partially reversible condition in abstinent ex-drinkers.

Background/Study Context: Employing the stereotype content model and terror management theory, we examined whether stereotypes and feelings about persons with dementia vary depending on the type of dementia diagnosis and purported causes of the dementia.

Methods: Participants were randomly assigned to read one of four vignettes that depicted a man who consulted his doctor because of memory problems. All vignettes described the same symptoms and diagnostic tests, but each of four groups read a different result: all tests normal (Normal); Alzheimer's disease (AD); Wernicke-Korsakoff Syndrome (WKS) associated with alcohol abuse; and chronic traumatic encephalopathy (CTE) associated with head injuries from playing football in high school and college.

Objective: Thiamine is an essential coenzyme for oxidative metabolisms; however, it is not synthesized in the human body, and the average thiamine storage capacity is approximately 18 days. Therefore, thiamine deficiency (TD) can occur in any condition of unbalanced nutrition. If TD is left untreated, it causes the neuropsychiatric disorder Wernicke encephalopathy (WE). Read More
