Contribution

In 1976, Kosaka described the concept of Dementia with Lewy bodies for the first time.[5] Two years later, he reported three autopsied cases of Dementia with Lewy bodies.[6]

The term Dementia with Lewy bodies was proposed at the first international workshop held in 1995, and is now in common use.[7]
