Carl or Karl Wernicke (// or //; Template:IPA-de) (15 May 1848 – 15 June 1905) was a German physician, anatomist, psychiatrist and neuropathologist. His first name has long appeared in print in both the Karl and Carl spelling variants (see Charles).
He earned his medical degree at the University of Breslau (1870). He later spent six months in Vienna, studying with neuropathologist Theodor Meynert, who would have a profound influence upon Wernicke's career. From 1876 to 1878 he served as a first assistant under Karl Westphal in the clinic for psychiatry and nervous diseases at the Berlin Charité. Afterwards, he founded a private neuropsychiatric practice in Berlin, and from 1885, served as an associate professor of neurology and psychiatry at Breslau. In 1890 he attained the chair at Breslau, later performing similar functions at the University of Halle (1904). He died the following year due to injuries suffered from a bicycle accident in the Thuringian Forest.
Studies in aphasia
Shortly after Paul Broca published his findings on language deficits caused by damage to what is now referred to as Broca's area, Wernicke began pursuing his own research into the effects of brain disease on speech and language. Wernicke noticed that not all language deficits were the result of damage to Broca's area. Rather he found that damage to the left posterior, superior temporal gyrus resulted in deficits in language comprehension. This region is now referred to as Wernicke's area, and the associated syndrome is known as receptive aphasia, for his discovery.
- Wernicke aphasia: The eponymous term for receptive or sensory aphasia. It is the inability to understand speech, or to produce meaningful speech, caused by lesions to the posterior superior temporal gyrus.
- Wernicke encephalopathy: An acute neurological dysfunction caused by a thiamine deficiency. It is characterized by the triad of ophthalmoparesis, ataxia and mental confusion. When combined with Korsakoff psychosis, a subacute dementia syndrome, it is then called Wernicke-Korsakoff syndrome.
- Wernicke's pupillary reaction: The absence of direct reaction to light in the blind part of the retina. First described by ophthalmologist Hermann Wilbrand in 1881.
