However, until now, there has not been a representative national survey documenting its prevalence in the U.S. adult population. This study reports on (a) the prevalence of terminal or unexpected lucidity in adults diagnosed with Alzheimer\u2019s disease or other dementias, and (b) its distribution across sociodemographic characteristics and parameters of clinical cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>Data are from a nationally representative population-based survey of observers (N = 5940) of dementia patients, aged 40+, who experienced one or more episodes of unexpected lucidity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The national prevalence of unexpected lucidity, according to observers, is 43.6% (weighted n = 2587).
