Aphasia is a loss of ability to use language because of the brain’s language area injury. Individuals who have aphasia, partially or completely are unable to express or understand words. In most individuals the nearby area of the frontal lobe and left temporal lobe controls language functions. Damage to any portion of such small area by head injury, stroke, infection, or tumors interfere with some aspect of language function. Language disorders take many forms. The different possible abnormalities are reflecting the language function complex nature. One individual can lose only the ability to comprehend written words (called alexia), while another individual can lose only the ability to say or recall the names of an object (called anomia). Some patients who have anomia may not remember the right words at all. While other can have words in their mind but are unable to say them. Another form of aphasia is dysarthria, in which inabilities to articulate word appropriately occurs. Dysarthria is resulted from injury to the brain part that controls the muscle used to coordinate vocal apparatus or make sounds. The form of aphasia, called Wernicke’s aphasia is a disorder, that can follow temporal damage of lobe, seem to talk fluently, but sentences coming out as confused, garbled word strings (in some cases referred to as aword salad). Individuals with another form of aphasia, known as Broca’s aphais, a largely grasps the word meaning and know how they wish to respond, but they have difficulties to say the word. Their words are frequently interrupted by expletives. Injury to both frontal and temporal lobes can make an individual almost fully mute. During recovery from global (complete) aphasia, an individual has dysphasia (impaired speech), verbal and writing (dysgraphia or agraphia) comprehension. A speech therapist may frequently help patients with developed aphasia after a head injury, stroke, or other. The treatment usually begins as soon as the individual’s medical condition permits
