Deterioration of declarative memory, which includes the ability to recall facts, events, and personal experiences, is the earliest and most severe indicator of Alzheimer's disease. Other symptoms such as loss of language and memory for well-learned behavior may also occur, but they are typically not as severe or early-stage indicators. Non-declarative memory, which includes skills and habits, may also be affected but typically comes later in the disease progression.
