In late adulthood, changes in memory may not be inevitable; however, any decline in memory tends to involve episodic memory. Episodic memory is the memory of autobiographical events such as time, places, associated emotions, and other contextual who, when, what, where, why knowledge, that can be explicitly stated or conjured. It is the collection of past personal experiences that occurred at a particular time and place. Examples of episodic memory include, the memories of what you ate for breakfast, your first day of college.
