Which of the following symptoms is characteristic of Major or Mild Neurocognitive Disorder with Lewy Bodies?

Fluctuating cognition and attention is a hallmark symptom of Major or Mild Neurocognitive Disorder with Lewy Bodies. This disorder is characterized by variations in cognitive function, where individuals may experience periods of confusion and impairment followed by periods of clarity. This fluctuation can significantly impact daily functioning and is notable in the clinical presentation of Lewy Body dementia.

In contrast, sudden changes in mood and behavior, persistent confusion regarding time and place, and clear awareness of cognitive deficits do not specifically define Lewy Body disorders. While mood changes may occur, they are not the defining feature of this condition. Persistent confusion regarding time and place is more indicative of other types of neurocognitive disorders, particularly in later stages. Lastly, individuals with Major or Mild Neurocognitive Disorder with Lewy Bodies typically do not have a clear awareness of their cognitive deficits, which aligns more with other dementias where patients may recognize their cognitive challenges. Thus, fluctuating cognition and attention is the defining and characteristic symptom of this specific neurocognitive disorder.
