What causes aphasia?
To the front lobe of the brain Individuals with Broca’s aphasia have harm. In short these individuals frequently speak, meaningful phrases that are produced with great effort. Broca’s aphasia is thus characterized as a nonfluent aphasia. Affected people often omit small words such as “is,” “and,” and “the.” A person with Broca’s aphasia may say, “Walk dog” meaning, “I will take the dog for a walk For example,.” The same sentence could also mean “You take the dog for a walk,” or “The dog walked out of the yard,” depending on the circumstances. Individuals with Broca’s aphasia are able to understand the speech of others to varying degrees. They are often aware of their difficulties and can become easily frustrated by their speaking problems Because of this,. Individuals with Broca’s aphasia often have right-sided weakness or paralysis of the arm and leg because the frontal lobe is also important for body movement.
Damage to the temporal lobe may result in a fluent aphasia that is called Wernicke’s aphasia in contrast to Broca’s aphasia. In long sentences that have no meaning, add unnecessary words, and even create new “words Individuals with Wernicke’s aphasia may speak.” For example, someone with Wernicke’s aphasia may say, “You know that smoodle pinkered and that I want to get him round and take care of him like you want before,” meaning “The dog needs to go out so I will take him for a walk.” Individuals with Wernicke’s aphasia usually have great difficulty understanding speech and are therefore often unaware of their mistakes. These individuals usually have no body weakness because their brain injury is not near the parts of the brain that control movement.
A third type of aphasia, global aphasia, results from damage to extensive portions of the language areas of the brain. Individuals with global aphasia have severe communication difficulties and may be extremely limited in their ability to speak or comprehend language.
