When a loved one makes unusual or seemingly dishonest statements, family members often worry and interpret the behavior as intentional deception. This behavior, however, is typically a symptom of cognitive impairment, not a character flaw or willful lying. Understanding the nature of these untrue statements within the context of cognitive decline is important for providing compassionate care.
The Distinction Between Lying and Confabulation
The behavior often mistaken for lying in individuals with dementia is a neurological phenomenon known as confabulation. Lying is an intentional act requiring awareness of the correct facts and a deliberate choice to mislead others. Confabulation, in contrast, is the unintentional creation of false memories or statements that the person genuinely believes to be true.
A person who confabulates is not trying to deceive; their brain attempts to fill memory gaps with fabricated or distorted recollections. Psychologists refer to this as “honest lying” because the statements are delivered with conviction, even if factually incorrect.
The statements can range from mundane inaccuracies to more elaborate stories about personal experiences. Since the individual is unaware the information is false, confronting them often leads to agitation. Confabulation is a memory error and a symptom of the disease, not a moral failing.
Neurological Basis for Fabricated Memories
Confabulation arises because the underlying neurological structures responsible for memory retrieval and monitoring are damaged by the progression of dementia. The brain struggles to maintain a coherent personal narrative when faced with significant memory gaps. This symptom is primarily attributed to damage in specific brain regions, particularly the frontal lobes and the medial temporal lobes.
The frontal lobes are responsible for executive functions, including reality testing, source monitoring, and the ability to evaluate the correctness of a memory. When these areas are affected, the brain loses its capacity to distinguish between a retrieved true memory and a created false one. This neurological impairment causes the individual to retrieve inaccurate information but accept it as fact.
The brain attempts to make sense of a confusing and disorienting reality by automatically generating a replacement memory to close the void created by memory loss. This is why a person with dementia may insist on the accuracy of their story; the fabricated memory is very real. The failure is in the process of memory retrieval and validation, illustrating that the behavior is a direct result of brain changes.
Strategies for Responding to Untrue Statements
Responding to confabulation requires a compassionate and non-confrontational approach, recognizing that correcting the facts will not change the brain’s error. The goal is to reduce distress and maintain the person’s dignity, not to win an argument. Directly challenging the false statement often causes the individual to become upset or defensive.
A helpful strategy is to focus on validating the underlying emotion rather than the factual content of the statement. For example, if a loved one insists they are late for work, you can acknowledge the feeling by saying, “I see you are worried about being on time.” This addresses their concern without reinforcing or correcting the false reality.
Caregivers can also use redirection to gently shift the conversation to a different, more familiar, or positive topic. This avoids dwelling on the inaccurate memory and prevents potential agitation. Simple, direct communication is beneficial, and open-ended questions that require complex recall should be avoided. Accepting the person’s reality, sometimes called “entering their reality,” is often the most effective way to ease anxiety and promote connection.
