Final answer:
True. The clinical assessment of cognitive impairment or neurocognitive disorders requires baseline data or normative data on older adults.
Step-by-step explanation:
True. The clinical assessment of cognitive impairment or neurocognitive disorders does require either baseline data on the individual's previous functioning and/or normative data on older adults within an appropriate comparison group.
This is important because it allows for a comparison to be made between the individual's current cognitive functioning and what would be expected based on their age and background.
By having this baseline or normative data, clinicians can better identify and diagnose cognitive impairments or neurocognitive disorders.
