📖 1. Aphasia Types

🔑 Key Concepts & Definitions

• Wernicke’s aphasia (disrupted speech comprehension): A syndrome characterized by impaired understanding of language alongside fluent but nonsensical speech output. Speech sounds well-formed, but the output is a jumble of words, often called "word salad" (source: Chapter 8).
• Broca’s aphasia (loss of fluent speech): A syndrome caused by damage to a specific region of the left hemisphere, resulting in non-fluent speech production while comprehension remains relatively intact (source: Chapter 8).
• Global aphasia (severe language impairment): A condition involving an inability to both comprehend and produce language, typically due to extensive left-hemisphere damage affecting both Broca’s and Wernicke’s areas (source: Chapter 8).
• Crossed aphasia (aphasia from right hemisphere): Loss of speech ability resulting from a right-hemisphere lesion in a right-handed individual, which is atypical since language functions are usually left-lateralized (source: Chapter 8).
• Conduction aphasia (disconnection syndrome): Characterized by an inability to repeat what was just heard, despite preserved comprehension and speech production, caused by damage severing the…
