Conduction aphasia
Conduction Aphasia
Conduction aphasia (/kənˈdʌkʃən əˈfeɪʒə/), also known as associative aphasia, is a rare form of aphasia that is characterized by the inability to repeat words or phrases. The term "conduction aphasia" was first coined by the German neurologist Carl Wernicke in the late 19th century.
Etymology
The term "conduction" is derived from the Latin word "conductio", which means "to lead or guide". "Aphasia" comes from the Greek word "aphatos", meaning "speechless". Thus, "conduction aphasia" can be interpreted as a condition where the guidance or transmission of speech is impaired.
Symptoms
Individuals with conduction aphasia typically have difficulty repeating words or sentences, even though they can understand what is being said and can speak fluently. They may also have difficulty finding the right words to express themselves, a condition known as anomia. Despite these challenges, their comprehension and spontaneous speech are usually preserved.
Causes
Conduction aphasia is usually caused by damage to the arcuate fasciculus, a bundle of nerve fibers that connects the Broca's area and Wernicke's area in the brain. These areas are responsible for speech production and comprehension, respectively. The damage can be due to stroke, brain injury, tumors, or infections.
Treatment
Treatment for conduction aphasia typically involves speech therapy, where individuals are taught strategies to improve their speech and language skills. The goal of therapy is to help the individual regain as much communication ability as possible.
