Is information in long term memory permanent?

No, some information may be lost over time in long term memory.

Long-term memory refers to the unlimited capacity store that can hold information for an extended period of time. However, it is not entirely permanent. The stability of long-term memory is influenced by various factors such as the frequency of the information being recalled, the emotional significance of the information, and the overall health of the individual. Over time, due to these factors and the natural process of aging, some information in long-term memory may be lost or become less accessible.
