Mild Cognitive Impairment (MCI) often affects memory. When memory fails, the brain sometimes compensates by attempting to fill in the gaps on its own. The technical term for this is confabulation. Confabulation might be the creation of “memories” for discussions or events that never actually happened, or it might be a distortion or elaboration of things that did happen. Sometimes, the confabulated story sounds very reasonable, while other times the gaps get filled in with outlandish or bizarre content.
Isn’t that lying?
Confabulation is not the same as lying. The person with memory loss truly believes what he or she is saying, as it feels like a real memory. The process happens automatically. For those close to the person with MCI, confabulation can be surprising or even scary at first. Spouses or adult children may feel embarrassed when it is obvious to others that the person with MCI is saying something that is not true. The person with MCI, in turn, may feel angry or humiliated when a family member corrects his or her version of a story.
Sometimes, confabulation is a mix of what the person with MCI has seen or heard in “real life.” It might be triggered by reading a story in the newspaper or watching a program on television. Imagine this scene: Gene has Mild Cognitive Impairment. Gene and his wife, Marge, are watching a television nature program about sharks, and shark attacks on humans. The next day, Marge overhears her husband on the telephone with their daughter, explaining that they cannot come to visit her in Florida as planned because last time they were there they were attacked by a shark.
Other times, confabulation happens when a situation does not make sense to the person with MCI due to memory difficulty. For example, Irene recently had to change the passcode for her cell phone. However, she forgot she did this, and now she keeps getting locked out of her phone for repeatedly typing in the wrong code. Her brain may try to help fill in the gap in her memory by coming up with the explanation that someone came into her apartment and changed the passcode for her cell phone. She may start to repeat this story to anyone who will listen, and will likely feel upset about it.
