The presence of VH predicted lower Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores in both DLB and AD patients (p\u2009&lt;\u20090.01). In DLB patients, VH were associated with lower attention function scores after adjustment (p\u2009=\u20090.027). In AD patients, VH were related to worsened orientation ability after adjustment (p\u2009=\u20090.033). Attention function partially mediated the association between VH and cognition in DLB patients (p\u2009&lt;\u20090.01), whereas orientation function partially mediated this association in AD patients (p\u2009&lt;\u20090.01).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>VH may independently correlate with deterioration in global cognitive performance.
