An interview\u2010based questionnaire about the presence of symptoms thought to be associated with Lewy body disease was completed by participants with, where possible, their carer\/relative. The prevalence of each symptom was compared between MCI\u2010LB and MCI\u2010AD and between established DLB and AD, and a symptom scale based on these findings was devised.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fluctuating concentration\/attention; episodes of confusion; muscle rigidity; changes in hand\u2010writing, gait and posture; falls; drooling; weak voice; symptoms of REM sleep behaviour disorder (RBD) and misjudging objects were more common in MCI\u2010LB compared with MCI\u2010AD, and also in DLB compared with AD. Hyposmia, tremor, slowness and autonomic symptoms were not specific to Lewy body disease. REM sleep behaviour disorder and hyposmia were reported to develop several years prior to the onset of cognitive symptoms in Lewy body disease. A 10\u2010point symptom scale differentiated between MCI\u2010LB and MCI\u2010AD with a sensitivity of 83% and a specificity of 100%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Drooling, misjudging objects and symptoms related to parkinsonism, fluctuating cognition and RBD may be the most characteristic symptoms of MCI\u2010LB. Slowness, tremor, autonomic symptoms and hyposmia are all common in MCI\u2010LB but are not specific to the disease.
