"Wernicke's aphasia"

Hello everyone,today i would like to tell about wernicke's aphasia in this post.
First of all what is the menaing of aphasia?

Aphasia-A language disorder that affects a person's ability to communicate.

Wernicke's aphasia-

Comprehension is impaired for spoken and written words and sentences.language output is fluent but is highly paraphasic and cicumlocutious.paraphasic errors may lead to strings of neologisms,which lead to "jargon aphasia."speech contains few substantive nouns.the output is therefore voluminous but uninformative.

For example , a patient attempts to describe how his wife accidentally threw away something important , perhaps his dentures : we don't need it anymore ,she says And with it ehen that was downstairs was my teeth -tick ....a...den...dentith ...my dentist .And they happened to be in that bag....see?..where my two....two little pieces of dentist that I use ...that I ...all gone .If she throws the whole thing away...visit some friends of hers and she can't throw them away..

Gestures and pantomime do not improve communication.the patient may not realize that his or her language is incomrehensible and may appear angry and impatient when the examiner fails to decipher the meaning of a severely paraphasic statement.In some patients,this type of aphasia can be associated with severe agitation and paranoia.the ability to follow commands aimed at axial musculature may be preserved.the dissociation betwee the failure to understand simple questions("what is your name") in a patient who rapidly closes his or her eyes,sits up, or rolls over when asked to do so is characteristic of wernicke's aphasia and helps differentiate it from deafness,psychiatric disease,or malingering.

Patients with wernicke's aphasia cannot express their thoughts in meaning-appropriate words and cannot decode the meaning of words in any modality of input.this aphasia therefore has expressive as well asreceptive components.repetition,naming,reading,and writing also are impaired.

The lesion site most commonly associated with wernicke's aphasia is the posterior portion of the language network.an embolus to the inferior division of the middle cerebral artery, to the posterior temporal or angular branches in particular,is the most common etiology.Intracerebral hemorrhage,head trauma, and neoplasm are other causes of wernicke's aphasia.a coexisting right hemianopia or superior quadrantonopia is common,and mild nasolabial flattening may be found,but otherwise,the examination is often unrevealing.

The paraphasic,neologistic speechin an agitated patient with an otherwise unremarkable neurologiv examination may lead to the suspicion of aprimary psychiatric disorder such as schizophrenia or mania,but the other components characteristic of acquired aphasia and the absence of prior psychiatric disease usually settle the issue.
Prognosis for recovery of language function is guarded.

Hope u understand something about wernicke's aphasia in this post.
