"elderly people typically have problems using memory, which requires keeping information activated (so that one is aware of it) while operating on it in a specific way."

The short-term memory

Explanation:

The memory is an abstract concept of the mind to store and retain information. It is a major function of the cerebral cortex in the brain. Memories are created from our daily experience, which is encoded systematically for productive purposes. For a memory to be created, the brain encodes external information or data, it is stored for a period of time and would be retrievable when needed.

The memory is categorized into long-term memory, short-term memory and working memory. The long term memory can be implicit, explicit or autobiographical long term memory.

Short term memory is controlled by the cerebral cortex, which is used to hold information currently in use, while cerebral cortex maintain attention and perpetual awareness for the active session.
