Final answer:
Patients suffering from clinical amnesia experience memory loss, particularly in forming and retaining new memories.
Step-by-step explanation:
Clinical amnesia is a disorder characterized by memory loss. Patients suffering from clinical amnesia have difficulty in forming and retaining new memories, but may still be able to remember events and information that occurred before the onset of the amnesia. This condition is known as anterograde amnesia, and it typically results from damage to the hippocampus, a region of the brain responsible for memory consolidation.
