False memories are a striking yet often overlooked symptom of Alzheimer’s Disease (AD), shaping the way patients perceive their past and interact with the present. While memory loss is a well-known hallmark of AD, false memories—where individuals recall events that never happened—can be just as disruptive. This piece explores the cognitive mechanisms underlying false memory formation in AD, drawing on research in psychology and neuroscience. By examining theories such as fuzzy-trace theory and schema-driven memory errors, this discussion sheds light on how AD patients reconstruct their past and the potential implications for diagnosis and intervention.
