What it is

Episodic memory is memory for events and experiences rather than a simple skill or fact list.[1,2]

Why it matters

People often notice problems here first because daily life depends on remembering appointments, conversations, places, and recent events.[1,3]

What it affects

  • Slower recall can occur with aging, while frequent lost items, missed events, or word-finding problems beyond peers can fit an MCI discussion.[1,3]
  • In Alzheimer disease, memory problems are often early because memory-related brain regions are affected early.[4]

Interpretation traps

  • Memory complaints can be affected by sleep, mood, medicines, sensory loss, delirium, stroke, tumors, thyroid, kidney, liver, and other causes.[1,5,6]
