A fluent aphasia where patients produce grammatically correct but nonsensical speech. Comprehension is significantly impaired.

• Speech pattern: Fluent, normal-sounding rhythm and rate
• Word choice: May use incorrect words (semantic paraphasias), nonsense words (neologisms), or substitute words
• Content: Speech may lack meaningful content despite fluency
• Comprehension: Significant difficulty understanding what others say
• Awareness: Often unaware of their speech errors

People with Wernicke's aphasia may speak in long sentences that sound normal in rhythm but contain errors or lack meaning. They may have difficulty following conversations, TV shows, or written material.

• Auditory comprehension exercises, like listening tasks
• Picture matching to improve word associations
• Controlled conversation practice with feedback
