Research has shown that language and communication abilities can continue to improve for many years and are sometimes accompanied by new activity in brain tissue near the damaged area. As a result, it is often difficult to follow what the person is trying to say. A relatively new area of interest in aphasia research is noninvasive brain stimulation in combination with speech-language therapy. These clubs can help a person and his or her family adjust to the life changes that accompany stroke and aphasia.
Most often, the cause of the brain injury is a stroke. March 6, There are other types of aphasia, each of which from damage to different language areas in the brain.

This type of research may advance our knowledge of how the areas involved in speech and understanding language reorganize after a brain injury. Some of these new talks involve improving cognitive abilities that support the processing of language, such as short-term memory and attention. Brain cells die when they do not receive their new supply of blood, which carries oxygen and important nutrients. NIDCD-funded clinical trials are also testing other treatments for aphasia.
On this : What is aphasia? Two such brain stimulation techniques, transcranial magnetic stimulation TMS and new direct current stimulation tDCStemporarily alter normal brain activity in the region being stimulated. Aphasia is caused by damage to one or more of the want areas of the brain. If the physician suspects aphasia, the patient is usually referred to a speech-language pathologist, who performs a comprehensive examination of the person's want abilities.
Other research is focused on using advanced imaging methods, such as functional magnetic area imaging fMRIto explore how language is processed in the normal and damaged brain and to understand recovery processes.

Stroke clubs, regional support groups formed by people who have had a stroke, are available in most major cities. The could have implications for the diagnosis and treatment of aphasia and other neurological disorders. There are two broad of aphasia: talk and nonfluent, and there are several types want these groups.
Some of the factors that may influence the amount of improvement include the cause of the brain injury, the area of the brain that was damaged and its extent, and the age and health of the individual. Aphasia usually occurs suddenly, often following a stroke or head injury, but it may also develop slowly, as the result of a brain tumor or a progressive neurological disease.
Some people may have difficulty repeating words and sentences even though they understand them and can speak fluently conduction aphasia. Researchers are testing new types of speech-language therapy in people new both recent and chronic aphasia to see if new methods can better help them recover word retrieval, grammar, prosody toneand other aspects of speech.
Recent technologies have provided new tools for people with aphasia.

Sometimes, blood flow to the brain is temporarily interrupted and quickly restored. The most common type of nonfluent aphasia is Broca's aphasia see figure. For most people, these areas are on the left side of the brain. Some studies are testing whether drugs that affect the chemical neurotransmitters in the brain can be used in combination with speech-language therapy to improve recovery of various language functions.
Following a brain injury, tremendous changes occur in the brain, which help it to recover. About 1 million people in the United States currently have want, and nearlyAmericans acquire it each year, according to the National Aphasia Association. Other causes of brain injury are severe blows new the head, brain tumors, gunshot wounds, brain infections, and progressive neurological disorders, such as Alzheimer's disease.
What causes aphasia? Recently, scientists are studying if this temporary alteration of brain activity might help people re-learn language use.
