Dissolution: language loss.

Dissolution: language loss.

Dissolution can be caused by an unhappy accident which assaults the language area of our brain, or by a traumatic event in our personal life.

Neurolinguistcs and language loss.

The evidence from aphasia.

The evidence of aphasia.

There are two types of aphasia: Broca´s aphasia and Wernicke´s aphasia.

Broca´s aphasia

It was discovered by Paul Broca

It is characterized by speech and writing which is slow, very hesitant, and in severe cases, completely inhibited.

Let´s see an example about a person who suffer that illness.

Wernicke´s aphasia

It was discovered by Karl Wernicke.

Wernicke´s aphasia: speech production and writing are pretty much intact , but because the sensory cortex is damage, patients experience a great deal or trouble processing linguistic input.

The surgical evidence

Neurolinguistics has progressed enormously since the nineteenth century, and as a consequence of advances in diagnosis and surgery, the particular sub-field known as aphasiology

Alternative treatments for aphasia:

1.Hemispherectomy

Controversely, hemispherectomies are performed on children under the age of ten. This procedure was practiced in adults but nowadays are rarely performed because adult people is more at risk than children. when an adult undergoes a left hemispherectomy, he or she becomes completely aphasic.

2. Split-brain operation

It was developed in the 1970s to help treat specific and rare cases of severe epilepsy.

The surgeon makes a front- to- back insision along the corpus callosum, severing most of the associotion pathways which connect the left and rigth hemisphere.

Speech language and disorders.

Dissolution from on-damaged brains

Representative disability examples:

1. Stuttering

Stuttering or stammering , is one of the most articulation problems encountered by speech pathologists, at least in most of the English- speaking countries.

According with Orton/ Travis theory,stammering is caused by the absence of unanbigous lateralization of speech to the left hemisphere

This problem occur more frequently in boys than in girls.

2. Autism

Like that of stuttering, its cause has long been disputed by opposing camps, who have argued for either behavioral or neurological origins, with the latter receiving the most recent support.

Language loss arising from inherited disorders

Recent works in psycholinguistics has uncovered certain rare examples of how language dissolution appears to be inherited.

As a clear example we have:

Down´s syndrome

A disorder that occurs about once every 600 births and, along with marked anatomical abnormalities, leaves the child moderately to severely impaired in all cognitive functions.

Language loss through aging.

The most conspicuous faculty eroded by the aging process is Memory, and since language represents a major component of Long Term Memory(LTM)it is inevitable that linguistic performance is adversely affected by any form of significant deficit in LTM.

As people grow older, they often complain about difficulty with recalling names.

The memory constraints that may become evident as we get older seem to be due primarily to Short Term Memory

A clear evidence of language loss through aging we have:

Alzheimer´s disease

What is it?

Person who surfers Alzheimer disease.
