Marked memory loss is likely to lead to which behavior in a client?

Marked memory loss often leads to confabulation, which involves the creation of false memories or distorted recollections without the intent to deceive. Individuals experiencing significant memory deficits may unconsciously fill in gaps in their memory by fabricating stories or details that seem plausible. This behavior arises as a way to compensate for the difficulties they face in recalling accurate information. The brain's natural mechanism attempts to maintain a coherent understanding of oneself and the environment, even if that understanding is not entirely accurate.

Confabulation is particularly relevant in cases of brain injury, dementia, or other cognitive impairments, where the individual may not be aware that their memories are incorrect. This behavior is different from intentional lying; rather, it originates from a genuine effort to retrieve lost information, albeit through false means. In contrast, while ideas of grandeur, need for attention, and marked memory impairment are related to cognitive and psychological issues, they do not specifically address the mechanism of compensating for memory loss as confabulation does.
