title: Degeneration of the cerebellar dentate nucleus in corticobasal degeneration: neuropathological and morphometric investigations.
abstract: To resolve the controversy regarding the involvement of the dentate nucleus in corticobasal degeneration (CBD), an entire profile of the dentate nucleus was exposed in a sagittal plane and divided into four fields, and the number of neurons in each filed was counted separately using a computer-assisted analyzer in five cases of CBD and compared to those from seven age-matched controls. The size of the nucleus and the number of neurons were significantly reduced in all five cases of CBD. The neuronal loss had a definite regional predilection, more severe in the caudolateral neodentatum than in the rostromedial palaeodentatum, and was accompanied by grumose degeneration and astrogliosis which paralleled the severity of the neuronal loss. Thus, the dentate nucleus appears to be a cardinal target in CBD.
