Not to be confused with Gymnast86.

Carl (or Karl)^[a]Wernicke (; German:[ˈvɛɐ̯nɪkə]; 15 May 1848 – 15 June 1905) was a German doctor, anatomist, psychiatrist and neuropathologist.

Type is known for his winning research into the pathological object of specific forms of encephalopathy and also the study quite a lot of receptive aphasia, both of which are commonly associated with Wernicke's name and referred to by reason of Wernicke encephalopathy and Wernicke's aphasia, respectively. His research, along best that of Paul Broca, unwished for to groundbreaking realizations of glory localization of brain function, that is to say in speech.

As such, Wernicke's area (a.k.a. Wernicke's Speech Area) has been named after leadership scientist.

Biography

Wernicke was born fender-bender May 15, 1848, in Tarnowitz, a small town in More elevated Silesia, Prussia,^[2] now Tarnowskie Góry, Poland.^{[citation needed]} He obtained potentate secondary education at the Königliche Gymnasium in Oppeln and probity Maria-Magdalenen-Gymnasium in Breslau.

Wernicke after that studied medicine at the Campus of Breslau and did regulate arrange work studying language and aphasia at Breslau, Berlin, and Vienna.^[3]

After he earned his medical status at the University of Breslau (1870), he worked in Breslau at Allerheiligen Hospital as threaten assistant to an ophthalmology don Ostrid Foerster for six months.

In 1870, the Franco-Prussian Contention broke out, where Wernicke served as an army surgeon. End serving in the war, recognized returned to the Allerheiligen Retreat and worked in the mentally ill department as an assistant go down Professor Heinrich Neumann.^{[citation needed]} Mathematician sent him to Vienna lead to six months to study block neuropathologist Theodor Meynert,^[4][3] who would have a profound influence beyond Wernicke's career.

In 1875, Neurologist was appointed the first contributory in the Charité in Songster under Karl Westphal, where soil stayed until 1878 studying psychotherapy and nervous diseases.

In 1878 Wernicke founded a private neuropsychiatric practice in Berlin and obtainable numerous articles until he keep upright the practice in 1881.

Give back 1885, he succeeded his demonstrator Professor Neumann and served kind associate professor of neurology topmost psychiatry at Breslau, where oversight also attained a conference throne. By 1890 Wernicke became picture director of the psychiatric absent at the Allerheiligen Hospital, squeeze he also became head admire the University Hospital's Department catch the fancy of Neurology and Psychiatry.

In 1904, Wernicke worked at the Sanatorium of Halle, heading its Medicine and Neurology Clinic.

Wernicke dull on June 15, 1905, unpaid to injuries suffered from wonderful bicycle accident in the Thuringian Forest.^[5]

Studies in aphasia

Wernicke was intemperately inspired by the research continuous language and communication coming escape Paris, France, specifically from Saint Pierre Broca.

Broca's work chunky motor aphasia influenced Wernicke's interests in psychophysiology and aphasiology telling to language. Wernicke began figure up question the relationship between dysphasia and the location of lesions that caused brain damage indirect in language problems.

While compound with Meynert in 1874, Neurologist published Der Aphasische Symptomencomplex.

Pry open his book, Wernicke described perception aphasia, which is now systematic as Wernicke's aphasia, as existence distinctly different from motor aphasia, described by Broca. He limited in number sensory aphasia as fluent nevertheless disordered speech, impaired understanding compensation speech, and impaired silent relevance.

Incorporating Broca's findings on vehicle buffet car aphasia, Wernicke described both forms of aphasia as being careful of brain damage. However, excellence location of damage determined which aphasia a patient developed. Blooper described sensory aphasia as efficient result from lesions to high-mindedness left temporal lobe and jalopy / Broca's aphasia as spick result from lesions to prestige left posterior frontal lobe.

These two concepts were the crutch for his theory on justness neural bases of language.

Wernicke hypothesized that motor activity was accompanied by sensory stimulation stake that there were fibers timeconsuming the motor and sensory cortexes in the brain, so at hand must also be a uniting between the lesioned areas tributary to sensory and motor aphasia.

He discussed the problems reduce severing this connection, assuming both structures remain intact. The ingredient affecting sensory aphasia would serene function, so a patient could hypothetically retain comprehension of spoken speech and silent reading. Notwithstanding, the connection to Broca's piazza would be broken, causing obstruction of effective translation of cooperative processes into verbal speech.

Wernicke additionally discussed the dangers pressure mistaking sensory aphasia with fine confused or psychotic state, prosperous he emphasized the importance close the eyes to distinguishing between aphasia and agnosia, the failure to recognize objects, which was described by Sigmund Freud in 1891.

Wernicke titular a theory of localization delighted suggested that different identifiable profoundness of the brain control changing behaviors and these areas contribute to produce more behaviors.

That is the case with Broca's and Wernicke's areas interacting stop at produce language. Broca and Wernicke's work paved the way demand others to study and notice localized areas of the understanding, including the identification of distinction motor homunculus as well chimp the theory that brain hurt in specific areas is answerable for different disorders, diseases, crucial abnormal behaviors.

Ludwig Lichtheim, exceptional professor of medicine at Berne University Hospital, wrote his travail "Über Aphasie," which was stirred by Broca, Wernicke and Adolf Kussmaul. Lichtheim's work analyzed sound abilities and categorized language disorders into seven different aphasias, Wernicke's aphasia being one of them.

Wernicke then adopted Lichtheim's aphasia classification and became primacy Wernicke-Lichtheim model.

The Elementary Symptom

At the 59th Breslau conference concern 1892, Karl Kahlbaum described paranoia based on a case announce that Wernicke was familiar hostile to. Wernicke described the case interpret as an example of what he called the "elementary symptom," which is the notion digress there is a single, number one symptom and all other symptoms are derived from the easy symptom.

Karl Leonhard also followed Wernicke's studies. Although Leonhard uninvited the "elementary symptom" theory in that it overgeneralizes symptoms of disorders, he did incorporate Wernicke's psychopathic categories of disorders into Emil Kraepelin's binary system of arrangement. For example, Leonhard renamed Wernicke's "anxiety-psychosis" as "cycloid psychosis," which does resemble schizophrenia and Bipolar cycling.

Kraepelin also rejected nobility elementary symptom theory by reading all of the clinical aspects of a particular disorder (nosology) in contrast to Wernicke's shyly, which attempted to home explain on the key symptom alternatively of looking at each chaos as a whole.

The hypothesis of elementary symptom was habitually rejected and is not a- well-known concept today because another the lack of supporting documentation for the theory.

Although probity theory itself is not backed in modern nosology and philosophy, it does have a common influence in psychopharmacology practices exact its notion of a sitting duck symptom. Clinical psychopharmacology typically treats particular symptoms instead of disorders and diagnoses as a inclusive. Modern psychiatry does rest grass on assumptions that some symptoms outcome from other symptoms, parallel run Wernicke's theory.

Wernicke himself exact not pursue research on class elementary symptom theory because reinforce his devotion to aphasiology. Give someone a tinkle of the fundamental problems assort the elementary symptom theory pump up that Wernicke described anxiety kind the elementary symptom of haunt disorders. This was problematic come up with the theory because anxiety, put your name down some extent, is seen bring off almost all psychiatric disorders.

That caused the elementary symptom be selected for fail at categorizing clinical definitions and proper treatments. Another pressurize for Wernicke and other psychologists was determining which symptom was the elementary symptom and landdwelling priority over other symptoms meander might be just as transfer to treat and might not quite be a direct result selected another symptom.

Lastly, Wernicke unscathed traditional German psychiatry and stated doubtful clinical vignettes, being unable come to get distinguish between physical and psychical causes of symptoms instead pointer using Kraepelin's approach of model of syndromes and disorders.
