Aphasia 

  Aphasia is language impairment. People are not able to communicate effectively when a specific area of the brain that controls language and speech gets damaged . The majority of the people who are affected with Aphasia are the People who had stroke but other injuries and brain diseases can also cause Aphasia.   

Dysphasia should not be confused with dysphagia which is a swallowing disorder. Dysphasia causes loss of speech but it is the partial loss of speech. People with dysphasia have difficulty with speaking, reading and writing. They struggle with remembering words and have a limited vocabulary. Dysphasia can be result of stroke, brain tumors, brain injuries or other brain diseases. People affected with Dysphasia might be able to speak fluently but they don’t make any sense. Aphasia is the term which is usually used to describe the both medical conditions: Aphasia and Dysphasia.   

Every person which is affected with Aphasia faces different type of speech difficulties depending on which area of the brain is affected. There are different kinds of Aphasia. Some of the types of Aphasia are: Broca’s Aphasia, Wernicke’s Aphasia and conduction Aphasia.   

Broca’s Aphasia is also known as the expressive Aphasia. Broca's is the area of the brain which is important in speech production. People who have Broca’s area damaged they are able to understand speech but they are not able to speak fluently. People with Broca’s Aphasia might be able to read but they may have difficulty with writing.   

Wernicke’s Aphasia is also known as receptive Aphasia. Wernicke’s is the area of the brain which plays an important role in processing the meaning of the words and speech. People with Wernicke’s Aphasia are impaired with speaking, reading and writing. They are able to say long sentences but they do not make any sense and they do not understand they are not making any sense.   

Conduction Aphasia is also known as associative Aphasia. Arcuate fasciculus is the part of the brain which connects Broca’s area and Wernicke’s area; since both of the areas play an important role in speech and language production when arcuate fasciculus is damaged people are able to hear and understand but they are not able to repeat words and phrases. They are also aware of the error they make in speech but they are not able to correct themselves.
