What term describes the inability to remember information stored in long-term memory?

The term that describes the inability to remember information stored in long-term memory is amnesia. Amnesia refers specifically to various types of memory loss, where individuals may find it difficult to recall past experiences or information that was previously accessible. This condition can occur due to several reasons, including brain injury, psychological trauma, or certain diseases.

While Alzheimer's Disease does involve memory loss, it is a specific degenerative condition that progressively affects cognitive functions, including memory. Confabulation, on the other hand, is a behavior often seen in individuals with memory disorders, where they fill in gaps in their memory with fabricated or misinterpreted information, rather than having a complete inability to remember. Hypnosis may influence memory recall but does not characterize a persistent memory impairment like amnesia does. Thus, amnesia is the most accurate term for the inability to remember information from long-term memory.
