Verified step by step guidance

1. Identify the key terms in the problem: 'new long-term declarative memories' and 'cannot be formed'.
2. Understand the concept of 'anterograde amnesia': It is a condition where an individual is unable to form new long-term declarative memories after the onset of the condition.
3. Differentiate between 'anterograde amnesia' and 'retrograde amnesia': Retrograde amnesia involves the loss of pre-existing memories, while anterograde amnesia affects the ability to create new memories.
4. Consider the context of 'declarative memories': These are memories that can be consciously recalled, such as facts and events, which are typically affected in anterograde amnesia.
5. Conclude that the inability to form new long-term declarative memories is characteristic of anterograde amnesia, as opposed to retrograde amnesia or loss of procedural memory.
