The NPSs were evaluated with the Neuropsychiatric Inventory (NPI), which measures severity in four domains: mood, psychosis, frontal, and total symptoms. Magnetic resonance imaging quantified regional gray matter volumes (GM), cerebrospinal fluid volume (CSF), and white matter hyperintensity (WMH) volumes to see their correlations with NPS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All volumes showed the smallest in dementia, the intermediate in MCI, and the largest in healthy controls. Higher total NPI scores were significantly associated with smaller volumes of hippocampal and gray matter volumes and larger cerebrospinal fluid volume, with the strongest correlations in the dementia group. By domain, NPI\u2010mood symptoms were correlated with reduced hippocampal, temporal, and frontal volumes. NPI\u2010psychosis symptoms also correlated with frontotemporal regions, but less extensively. Mood symptoms were most strongly linked to temporolimbic atrophy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n
