Wernicke's Fissure
Wernicke syndrome is an ambiguous term. It may refer to: * Wernicke aphasia: the eponymous term for receptive or sensory aphasia. *Wernicke encephalopathy: an acute neurological syndrome of ophthalmoparesis, ataxia, and encephalopathy brought on by thiamine deficiency. *Wernicke–Korsakoff syndrome, also called Korsakoff psychosis: a subacute dementia syndrome, often following Wernicke encephalopathy, characterized clinically by confabulation and clinicopathologically correlated with degeneration of the mammillary bodies. See also *Carl Wernicke (1848–1905), the neurologist who described all of these syndromes. *Wernicke's area Wernicke's area (; ), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to ...

Receptive Aphasia
Wernicke's aphasia, also known as receptive aphasia, sensory aphasia, fluent aphasia, or posterior aphasia, is a type of aphasia in which individuals have difficulty understanding Written language, written and spoken language. Patients with Wernicke's aphasia demonstrate fluent speech, which is characterized by typical speech rate, intact syntactic abilities and effortless speech output. Writing often reflects speech in that it tends to lack content or meaning. In most cases, motor deficits (i.e. hemiparesis) do not occur in individuals with Wernicke's aphasia. Therefore, they may produce a large amount of speech without much meaning. Individuals with Wernicke's aphasia often suffer of anosognosia – they are unaware of their errors in speech and do not realize their speech may lack meaning. They typically remain unaware of even their most profound language deficits. Like many acquired language disorders, Wernicke's aphasia can be experienced in many different ways and to many d ...

Wernicke Encephalopathy
Wernicke encephalopathy (WE), also Wernicke's encephalopathy, or wet brain is the presence of neurological symptoms caused by biochemical lesions of the central nervous system after exhaustion of B-vitamin reserves, in particular thiamine (vitamin B1). The condition is part of a larger group of thiamine deficiency disorders that includes beriberi, in all its forms, and alcoholic Korsakoff syndrome. When it occurs simultaneously with alcoholic Korsakoff syndrome it is known as Wernicke–Korsakoff syndrome.Ropper A, Brown R. Princ. of Neurology, Adams & Victor. 8º ed. McGraw Hill 2007. Classically, Wernicke encephalopathy is characterised by a triad of symptoms: ophthalmoplegia, ataxia, and confusion. Around 10% of patients exhibit all three features, and other symptoms may also be present. While it is commonly regarded as a condition particular to malnourished people with alcohol misuse, it can be caused by a variety of diseases. It is treated with thiamine supplementatio ...

Wernicke–Korsakoff Syndrome
Wernicke-Korsakoff syndrome (WKS), colloquially referred to as wet brain syndrome, is the combined presence of Wernicke encephalopathy (WE) and Korsakoff syndrome. Due to the close relationship between these two disorders, people with either are usually diagnosed with WKS as a single syndrome. It mainly causes vision changes, ataxia and impaired memory. The cause of the disorder is thiamine deficiency, thiamine (vitamin B1) deficiency. This can occur due to eating disorders, malnutrition, and alcohol abuse. These disorders may manifest together or separately. WKS is usually secondary to prolonged alcohol abuse. Wernicke encephalopathy and WKS are most commonly seen in people with an alcohol use disorder. Failure in diagnosis of WE and thus treatment of the disease leads to death in approximately 20% of cases, while 75% are left with permanent brain damage associated with WKS. Of those affected, 25% require long-term institutionalization in order to receive effective care. S ...

Carl Wernicke
Carl (or Karl) Wernicke (; ; 15 May 1848 – 15 June 1905) was a German physician, anatomist, psychiatrist and neuropathologist. He is known for his influential research into the pathological effects of specific forms of encephalopathy and also the study of receptive aphasia, both of which are commonly associated with Wernicke's name and referred to as Wernicke encephalopathy and Wernicke's aphasia, respectively. His research, along with that of Paul Broca, led to groundbreaking realizations of the localization of brain function, specifically in speech. As such, Wernicke's area (a.k.a. Wernicke's Speech Area) has been named after the scientist. Biography Wernicke was born on May 15, 1848, in Tarnowitz, a small town in Upper Silesia, Prussia, now Tarnowskie Góry, Poland. He obtained his secondary education at the Königliche Gymnasium in Oppeln and the Maria-Magdalenen-Gymnasium in Breslau. Wernicke then studied medicine at the University of Breslau and did graduate work st ...
