Which type of aphasia is characterized by anterior lesions?

• A. Fluent aphasia
• B. Non-fluent aphasia
• C. Global aphasia
• D. Anomic aphasia

Answer: (B)

Non-fluent aphasia is characterized by anterior lesions, typically found in Broca's area, which is located in the left frontal lobe of the brain. Individuals with non-fluent aphasia often have difficulty with speech production; their speech is typically slow, effortful, and may contain grammatical errors. They often understand spoken and written language better than they can express themselves verbally. This type of aphasia arises from damage to the areas of the brain responsible for language production, which is why fluency is affected. The anterior lesions impair the motor aspects of speech, leading to the defining characteristics of non-fluent aphasia. In essence, the location of the brain injury plays a critical role in the type of aphasia expressed, making non-fluent aphasia the correct identification for anterior (frontal lobe) lesions.
