Parkinsonian features have been reported in up to 30% of ALS patients, and Lewy bodies, normally associated with Lewy body disease (LBD), have been reported in a small number of ALS cases, with unknown clinical relevance. This study investigates the prevalence of clinically relevant LBD in a prospectively studied ALS cohort to determine whether concomitant pathology contributes to the clinical heterogeneity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>All ALS cases held by the New South Wales Brain Bank (<jats:italic>n<\/jats:italic>\u00a0=\u00a097) were screened for coexisting LBD consistent with clinical disease (Braak\u00a0\u2265\u00a0stage IV).
