history
The (cortical) sensory aphasia called Wernicke's aphasia was first described in 1874 by the German psychiatrist Carl Wernicke in Breslau.

Patients with this type of language disorder can speak fluently, even excessively, but cannot understand the meaning of the words. The disorder can also occur in connection with logorrhea .
It is primarily the “ mental lexicon ” that is affected. Designations are difficult to call up and use the correct sound sequence. This creates words that do not exist in the respective language ( neologisms ); In the worst case, you can no longer make sense of the spontaneous speech of a Wernicke aphasic, because almost every word that contains content has been greatly changed.
- Example: "I've got glues made today, made as and when then the banzerin is come, the bakzarin " ... and then on and on.
Furthermore, patients often use paraphasias and are prone to paragrammatism . Since the understanding of speech for words and sentences is severely impaired, verbal communication with patients with Wernicke aphasia is very difficult. In addition, there is a writing disorder, more often in the form of paraphasic distortions, and a reading comprehension disorder .
