Come again? A Look Into Left Hemisphere Aphasia

Imagine you are with your loved one on Saturday night. When you watch a movie, you will feel very strange. Suddenly I can not move my feet nor move my face. The image on the TV screen is doubled everywhere, and I have a headache. Your other important people seem to be crazy talking to you, but you do not understand what they are saying, they can not answer. It's as if you are trapped in your own body (Rodriguez).

Aphasia is a language disorder caused by partial damage to the brain responsible for the language. For most people, these are part of the left side (hemisphere) of the brain. Aphasia usually occurs suddenly as a result of stroke or head trauma usually, but it can also develop slowly like a brain tumor. This disease not only impairs language expression and understanding, it also impairs reading and writing. Aphasia can occur simultaneously with speech disorders such as dysarthria caused by brain damage or language disappearance as well.

The association between brain injury and aphasia was at least 3,000 years ago (O'Neill, 1980). For over 100 years, researchers have also found that aphasia is more likely to occur on the left side of the brain, and depending on the nature of the injury and its location in the left hemisphere, different types of aphasia can occur. Goodglass, 1993). Paul Broca was the first person who linked defects that occurred in language to damage in the front of the left hemisphere, now known as Broca District. Carl Wernicke later discovered contrastive forms of aphasia. This is characterized by lack of understanding in the presence of fluent words and is usually associated with damage to the rear area of ​​the left hemisphere known as the "Wernicke area". These findings have caused a dispute over the century that remains unresolved on the nature of these and other contrasting aphasia, and their neurological relevance.

Language defects, localization and grammar: evidence for models of language breakthrough in subtropical patients and neuroscientists

If the forehead of the left hemisphere is damaged by a stroke, problems of various kinds of languages ​​may occur. This part of the brain is very important to combine words to form a complete sentence. Damage to the left frontal lobe can lead to so-called Broca aphasia. Broca Aphasia survivors: Friends of language pathologists said they had a bad day for the patient. She said "I was bitten by a dog," a stroke survivor asked, "Why are you doing this?" In this conversation, the patient understood basic words, but did not understand sentences and orders. Words are essential for explaining the correct meaning of sentences. In other words, dogs chew women, not other ways.
