Confabulation is not lying. False memories due to brain injury.

Memories are a strange thing. We put so much trust into them. When someone accuses us of something we didn’t do, we are offended. But what if our memory just isn’t right, and we have a false memory of the same event? This is confabulation, which isn’t uncommon after a brain injury.

Catherine E. Myers from  Memory Loss and the Brain, describes it like this:

“Confabulation is a memory disorder that may occur in patients who have sustained damage to both the basal forebrain and the frontal lobes, as after an aneurysm of the anterior communicating artery. Confabulation is defined as the spontaneous production of false memories: either memories for events which never occurred, or memories of actual events which are displaced in space or time. These memories may be elaborate and detailed. Some may be obviously bizarre, as a memory of a ride in an alien spaceship; others are quite mundane, as a memory of having eggs for breakfast, so that only a close family member can confirm that the memory is in fact false.”  http://www.memorylossonline.com/glossary/confabulation.html

There’s one thing knowing that following a brain injury you can be forgetful. But when what you think you remember might not be the truth, then how are you supposed to feel?

Brain injury and confabulation
Provoked confabulation

Patients can most commonly have a provoked confabulation, which is when they are trying to answer a question.Therefore it’snot something they have been thinking about before hand. But try to recall in order to answer the question.

 

I first realised that this sometimes was happening to me when a Neurologist, asked me to describe my journey home from The Royal London Hospital. This was after I had been an inpatient for 10 days following a car accident which caused my brain injury. Easy. I recounted how it was a fairly bright, dry day, and that I talked throughout the trip, pleased with having company. But then he asked my chauffeur that day, my partner James, if that sounded right. No, it was pretty much nonsense. He said I had been extremely quiet, to the point he wasn’t sure if I was still awake. And being after 4 pm in late December, it was dark outside.

Spontaneous confabulation

This is much less common, and is where without being asked about it, a patient will recall an untrue event. At this stage I can’t think of any examples I have of this happening to me. It is much less common, but as all memories feel real, it takes a witness to be able to confirm or deny them. James would be your man for that, but he’s at work now so that question will go unanswered for now.

Autobiographical memory

Usually it is the autobiographical memory which is being affected by neurological issues. This type of memory is how we categorise our own life experiences. Therefore we are used to putting our confidence in them. But this is why it’s important that people understand that confabulating is not lying. The suffer genuinely believes the story they are telling is real. They are not trying to mislead anyone, so a calm approach is needed in this situation.

Dealing with confabulation

When you are talking to someone who is confabulating, there are 3 things you need to understand:

  1. It can be a way of the patient making sense of the situation. Although inaccurate, if can be comforting to them to feel they have a handle on things.
  2. Personal identity is important to us all, but if your autobiological memory is letting you down, how do you reconcile this? Well, maybe that’s why these false memories happen, perhaps we want to understand who we are and where we fit in.
  3. It’s a form of interaction. If you don’t remember much, what do you talk about? Humans are social creatures and we all need to feel we have something to add.

So taking these 3 points into consideration, it’s usually better to not correct the patient. Imagine how distressing it would be if someone told you we all live on Mars and Earth died 200 years ago. Clearly that isn’t the case, but that confusion is what it feels like for someone who has just been told their confabulation is wrong. Usually, like my rose tinted memory of my journey home form the hospital, it’s harmless anyway. So if you can, just bear with us.

  1. My family sort information from a Carer organisation to better understand my ABI. They set them down a path that I apparently do this. And they hadn’t even bothered to meet me. So, not happy! Bless

    1. Perhaps they meant to explain it’s a possible explanation for some things you have said that your family didn’t agree with? But with just one side of their story they shouldn’t have let your family believe it was the only possible reason. Sometimes odd things happen but if no one else witnesses if with you, others might think you have it wrong.
