Receptive aphasia

Wernicke's aphasia ( formerly called sensory aphasia) is a named after Carl Wernicke form of language disorder aphasia.

History

Wernicke's aphasia was first described in 1874 by the German psychiatrist Carl Wernicke.

Formation

The speech disorders occur with a lesion in the posterior ( rear ) supply area of ​​the middle cerebral artery ( Brodmann 's area 22).

Effects

Patients with this type of language disorder can fluently speak even excessively, but do not recognize the meaning of the words. The disorder may further occur in conjunction with logorrhoea.

It is affected primarily the " mental lexicon ". Designations may be poorly accessed and implemented in the correct sequence of sounds. This results in words that do not exist in the language ( neologisms ); in the worst case, you can refer to no more sense of the spontaneous speech of Wernicke's aphasic, because almost any content- bearing word is greatly changed.

Furthermore, patients often use paraphasias and tend to paragrammatism. Since the speech understanding of words and sentences is severely disrupted, a verbal communication with patients with Wernicke 's aphasia is very difficult possible. In addition there are a writing disorder, often in the form of paraphasischen distortions, and a failure of reading comprehension.
