Several studies
have found that confabulation is rather common among individuals who have not
been diagnosed with any type of brain disorder. The book Brain Fiction includes a review of expanding scientific research that provides
evidence and conclusions that confabulation is not something restricted to
psychiatric patients or to those who fantasize. The evidence shows that human
beings produce a body of narratives or stories every day. Many of these
stories are thought to help explain how they feel, the reason they made a
specific decision, the underlying prompts for judgments they made, why they exhibited
the behavior they did and the reason they took the actions they did, and so
on. Typically, these stories are a combination of fact and fiction, although
the individuals involved believe that what they said was completely true. It
gives one pause and perhaps can provide some impetus for becoming more aware
of and evaluating the stories one tells the self and others.

Confabulation and the Brain, 6
In the book Brain Fiction: Self-Deception and the Riddle of Confabulation, the author indicated that confabulation
is not just a deficit of memory; it is something anybody might do, even people
with perfectly fine memories and healthy brains. For example, children and many adults confabulate when encouraged to talk about things of which
they have no actual knowledge or when trying to make something seem
less important or more important. Eyewitnesses can be influenced by suggestive
inquiries to confabulate. The evidence shows that many of the stories human
beings produce on a daily basis to explain how they feel, the reason they did
something, or the process used to come up with a decision, are confabulations,
mixtures of fact and fiction that the individuals believe to be completely
true. The study conclusions might be an impetus to realize that probably
everyone at some time or another uses confabulation and it is possible they do
not even realize what they are doing, believing whatever they utter is the
absolute truth.

Confabulation and the Brain, 5
PsychCentral
identifies two types of confabulation: spontaneous and provoked. A
provoked confabulation is when a patient invents an untrue story in response to
a question and tends to occur quite
commonly among patients with amnesia or dementia. On the other hand, a
spontaneous confabulation tends to occur less commonly and involves
the telling of an untrue story with no apparent motivation. Sometimes confabulations are verbal and only
involve talking about false memories. Behavioral
confabulations, on the other hand, occur when the patient acts upon his or her erroneous
beliefs. Most studies on
confabulation have focused on symptoms related to underlying problems or
pathologies that impact memory. Recently, attention is focusing on individuals
without identifying underlying problems who exhibit confabulation. More
tomorrow.

Confabulation and the Brain, 4
Wikipedia puts it this way: In psychiatry, confabulation is a memory
error defined as the production of fabricated, distorted, or misinterpreted
memories about oneself or the world, without the conscious intention to
deceive. People who confabulate present incorrect memories ranging from
"subtle alterations to bizarre fabrications", and are generally very
confident about their recollections, despite evidence to the contrary. The free
medical dictionary points out that confabulation involves the unconscious filling in of gaps in memory
with fabricated facts and experiences, commonly associated with organic
pathology. It differs from lying in that the patient has no intention to
deceive and believes the fabricated memories to be real. More tomorrow.

Confabulation and the Brain, 3
There
are a couple of key components of confabulation (according to the Massachusetts
Institute of Technology).
1.
An individual provides a false response to a
question. For example, “What is your favorite vacation spot?” and the answer is
“Alaska, of course,” even though they have never even been to Alaska.
2. The other component
is that the individual believes what he or she just said without giving it
another thought.
This is
different from individuals who tell a lie on purpose and know consciously that
they are in fact telling a lie.
Someone without an underlying memory problem tends to say
“I don’t know,” if asked a question they either do not know the
answer to or can’t remember at the moment. Confabulation involves
subconsciously creating a story to cover what they cannot think of.

Confabulation and the Brain, 2
No one specific
cause for medical or psychiatric confabulation has been identified although several types of syndromes
and disorders may underlie the symptoms, including:
- Memory disorders,
such as Alzheimer’s and other dementias
- Traumatic
brain injury
- Anton’s syndrome, or denial of
blindness
- Capgras syndrome, the belief that
an imposter has replaced a loved one
- Korsakoff syndrome
- Schizophrenia
- Split-brain
syndrome
- Aneurysm
More tomorrow.

Confabulation and the Brain
Karl Bonhoeffer,
a German psychiatrist, is credited with coining the term “confabulation” in 1900 to describe a type
of memory loss that negatively impacts an individual’s higher-reasoning ability. Not a disorder in and of itself, confabulation
is—in manyt cases—the symptom of an underlying condition that impacts
memory accuracy. Although not relegated to one specific cause, it appears that
individuals exhibiting confabulation tend to have damage in the frontal lobes
of the brain and in the corpus callosum, the largest bridge that connect the
two cerebral hemispheres. Confabulation is typically a subconscious strategy used when an individual has a condition that
impacts his or her memory. These individuals create stories as a way to hide
their memory loss. Although many have the mistaken idea that these people are “telling
lies,” the individuals themselves are unaware that they are not telling the
truth. They have no doubt that what they are saying is true, even though others
know that the story is false. More tomorrow.
