Lewy body disease includes clinically and pathologically defined disorders in which Lewy bodies occur in the nervous system. In recent years, the molecular features of these disorders have been emerging. Several genetic loci have been identified in association with familial Lewy body disease; however, the genetic risks underlying most cases of familial Lewy body disease remain to be discovered. The fact that Lewy bodies stain strongly with antibodies to -synuclein and that mutations in the -synuclein gene lead to syndromes in which parkinsonism and dementia occur gives us important clues regarding the biologic processes leading to disease. Pursuit of additional mendelian causes of familial Lewy body disease and study of the factors contributing to the complex phenotypes associated with Lewy body disorders will elucidate underlying disease pathways and, thus, possible targets for therapeutic intervention.
