Aphasia - Symptoms and treatment

Disease - Aphasia

Definition of aphasia

Aphasia is defined as the loss or disturbance of the ability to speak due to a lesion in the language areas of the cerebral cortex. The motor aphasia affects mainly the ability to express themselves, while in sensory aphasia is the ability to understand the speech of others.

Therefore, aphasia is a neurological disorder caused by damage to the parts of the brain that are responsible for language.

Symptoms of Aphasia

The main symptoms of the disorder include difficulty in speaking speak, understand speech problems and difficulty reading and escribir.La aphasia is not a disease but a symptom of brain injury. Most often seen in adults who have had a stroke or as a result of a brain tumor, infection, head injury or dementia that damages the cerebro.Se estimated that about one million people in the United States suffer from aphasia at present. The type and severity of language dysfunction depends on the precise location and extent of brain tissue damage.

Types of aphasia

Generally, aphasia can be divided into four main categories:

1 .- Expressive aphasia involves difficulty to convey thoughts through speech or escritura.El patient knows what that means, but can not find the words you need.

2 .- receptive aphasia involves difficulty understanding spoken or escrito.El patient hears the voice or sees the print but can not understand the words. (

3 .- anomic aphasia or amnesia. Patients with anomic aphasia or amnesia, the less severe form of aphasia, have difficulty using the correct names of certain objects, people, places or events.

4 .- global aphasia from a serious injury and extensive areas of language in the cerebro.Los patients lose almost all language function, both comprehension and can not speak or understand expresión.No what they say, nor can read or write.

In some cases, the person can recover completely from aphasia without treatment. However, in most cases, begin speech therapy as soon as possible, adjusting to individual needs rehabilitation paciente.La language pathologist includes extensive exercises in which patients read, write, follow directions, and repeat what oyen.La computer-assisted therapy can complement standard speech therapy.

What is the prognosis of aphasia?

The evolution of aphasia is difficult to predict given the wide range of variability of the condition. In general, younger people or less extensive brain damage has better evolución.La location of the lesion is also important and is another key to the outcome. In general, patients tend to regain skills of language comprehension more completely than those skills involving expression.

Research on aphasia

The National Institute of Neurological Disorders and Stroke (NINDS, for its acronym in English) and the National Institute on Deafness and Other Communication Disorders (NIDCD, for its acronym in English) conduct and support a wide range of research science to improve our understanding of aphasia, find better treatments and find more accurate methods to restore lost function to people with aphasia.
