Confabulation

Confabulation is the production of fabricated, distorted, or misinterpreted memories about oneself or the world, without the conscious intention to deceive. These false memories, which are often plausible and detailed, arise primarily in individuals with brain damage or neurological disorders, most commonly associated with amnesia and Korsakoff's syndrome. The person believes their confabulated accounts to be true, and they are not lying but are experiencing a memory disturbance that makes them believe what they are creating as a real experience. Confabulation differs from lying; it is a symptom of a neurological condition, where the person lacks awareness of the fabrication. The underlying cause of Confabulation is typically damage to the frontal lobes and related structures of the brain, which are critical for memory retrieval and source monitoring. Impairment in these areas makes it challenging to distinguish between real and imagined events, or to determine when the memory came from or if it even happened. Individuals often fill in the gaps in their memory with invented stories to make sense of their experiences, leading to the unintentional creation of false narratives that appear coherent and consistent to the individual and anyone else. These stories might encompass the individual's life, surroundings, and immediate needs.
