However, there was poor agreement for NPS presence across depression metrics (6%) and across anxiety metrics (7%). Choice of metric could greatly skew the frequency of an NPS being present. All 3 affective NPS were more common in Lewy body disorder compared to Alzheimer's disease or vascular cognitive impairment, regardless of metric.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Though NPIQ severity rating cut-off choice should depend on study design, using a severity score of &gt;1 for presence and =0 for absence may best fit clinical gestalt for affective NPS.
