Neurocognitive disorder due to Lewy bodies is characterized by which symptoms?

Consistent long-term memory retention and clear cognitive function
Short-term memory loss, unpredictable cognitive shifts, and sleep disturbances
Severe language impairment and loss of basic motor skills
Progressive hearing loss and visual hallucinations

The correct answer is: Short-term memory loss, unpredictable cognitive shifts, and sleep disturbances

Neurocognitive disorder due to Lewy bodies is primarily characterized by symptoms such as short-term memory loss, unpredictable cognitive shifts, and sleep disturbances. Patients often experience fluctuations in their cognitive abilities, which can lead to confusion or disorientation at times, followed by periods of clearer thinking. This variability in cognitive function is a key feature of the disorder. Additionally, sleep disturbances, such as REM sleep behavior disorder, are common as well, where individuals may act out their dreams. These symptoms highlight the complexity of Lewy body dementia, differentiating it from other forms of neurocognitive disorders, where symptoms tend to be more stable or predictable. The presence of these specific features is crucial for identifying and diagnosing this condition effectively.
