Human beings occasionally suffer bad damage to particular parts of their brains. Unfortunately, these injuries may lead to major failure of speech production, understanding language and comprehension which most of the patients suffer it permanently. This impairment is called Aphasia. Gayle (2012) states that people with aphasia fail to understand sentence comprehension although it is a simple sentence. She also mentioned that aphasia patients also have difficulty in reading and understanding speeches. According to Fromkin, Rodman and Hyams (2011), aphasia is a scientific term used to explained language disorder due to brain injuries caused by diseases or trauma. In other words, aphasia involves partial or total loss of the ability to …show more content…
Scott (2000) suggests that closed head injury happens due to accident. When the skull has been knocked by a hard surface, the brain is twisted pushed against the skull which resulted contusion and damage to the frontal part of the left side of the brain which is dominant for language. Scott also emphasizes that the skull may be fractured due to the hit but the tissue coverings are unimpaired and there is no penetration of the skull. Nevertheless, patients with closed head injury will not be able to produce speech due to the damage. Therefore, their impairment can be considered as Broca’s aphasia. On the other hand, the other cause that can lead to Broca’s aphasia is open head injury. This injury is more severe than the closed head injury. Kaur and Wolff (2012) report that open head injury may cause diffusion of the skull because the shape of the skull is badly damaged and the tissue beneath it is completely destroyed. As a result, injured patient produces halting speeches which can be considered as Broca’s aphasia.
Besides that, Broca’s aphasia can also be caused by infectious diseases to the left side of the brain. Infectious diseases are caused by bacteria and very dangerous because these diseases may damage the brain tissue of the patient. According to Kaur and Wolff (2012), the effects of the diseases may be temporary if it can be treated. But if it is severe, it may cause permanent brain damage to the tissue at the
