How long does long term memory last?

Long-term memory is a type of memory that allows for the storage of information over extended periods, potentially lasting indefinitely. This form of memory is characterized by its ability to retain information ranging from personal experiences, knowledge, skills, and facts for many years or even a lifetime.

The duration of long-term memory is not strictly limited by a specific time frame and can persist as long as the information remains relevant and is sometimes recalled or used. While some memories may fade over time, they do not necessarily disappear unless intentionally forgotten or if there are psychological factors involved, such as trauma or certain neurological conditions.

The nature of long-term memory also includes mechanisms for reconsolidation, where memories can be strengthened or altered upon retrieval, thereby maintaining their presence in the brain for long periods and allowing for the retention of vast amounts of information.
