Aphasia
Aphasia
Aphasia can be defined as a communication disorder that is in result to the damage of a certain part of the brain, usually the left or right hemisphere of the brain, which is responsible for language and understanding. In normal physiology, language is assigned to different parts of the cerebral cortex of the brain (3). The Wernicke area, which is located on the left hemisphere of the brain, recognizes both written and spoken language (3). In addition to recognizing written and spoken language, the angular gyrus which is superior to the Wernicke area functions in reading and writing (3). The Wernicke area is also involved in creating a plan of speech to the Broca area (3). The Broca area prepares the steps necessary for motor skills of the facial muscles to produce speech (3). The Primary cortex of the brain is what actually executes the plan of speech (3). Particularly damage to these areas causes aphasia in result of a stroke, which is when blood is unable to reach a part of the brain (4). Other causes of brain injuries that could cause aphasia are brain tumors, severe blows to the head and undeveloped portions of the brain. Aphasia does not reduce or stops a person’s intelligence, but only the person’s ability to communicate, read or comprehend (5). There are various types of aphasia which can be difficult to categorize because they can vary from mild to severe in different cases. With mild Aphasia a person may be able to communicate but may have trouble understanding a complex conversation or finding the right words for that conversation (1). Severe Aphasia reduces the person’s ability to communicate tremendously; the person may only say little or not speak at all. Common types of Aphasia are the following: expressive, receptive, anomic, global and primary progressive Aphasia (5). Two main types of Aphasia occur in the Broca’s area and Wernicke’s area of the brain. Broca’s aphasia is the most common non-fluent in speech aphasia, which can result in
