<unk> , or Wernicke’s<unk> , fluent<unk> , or sensory<unk>  is the most common type of<unk> , often (but not always) caused by neurological damage (stroke) to Wernicke’s area in the brain (Broddman area 22, in the posterior part of the superior temporal gyrus of the dominant hemisphere). This is not to be confused with Wernicke’s encephalopathy or Wernicke-Korsakoff syndrome. The<unk>  was first described by Carl Wernicke and its understanding substantially advanced by Norman Geschwind. Patients with this type of<unk>  are usually not aware of the errors they may be making while speaking, or that it may not be logical.
Wernicke's<unk>  may present with other deficits such as dysarthria, and severity depends on the lesion present though usually without motor dysfunction. This leads to proper stringing of words together to form fluent speech even though it is often without meaning. Language expression deficits can be accompanied with memory deficits, impaired understanding of language along with impaired reading and writing.
