Original abstract
Neuropathological studies show that about 20% of all patients suffering from an acinetic-rigid syndrome can not be given the diagnosis of idiopathic Parkinson's disease. Among these non-idiopathic Parkinson-syndromes the corticobasal degeneration (CBD) can be regarded as a separate disease entity. The pathological findings of moderate predominantly frontal and parietal cerebral atrophy, cortical Pick-cells and specific corticobasal inclusion bodies are considered valuable features which support the diagnosis. The clinical Characteristics of CBD are demonstrated in 3 patients including an acinetic-rigid syndrome, limb apraxia and "alien limb"-syndrome, as well as reflex myoclonus. Eye movement disorders, dementia and other rare symptoms may also be present. Electrophysiological reflex-testing helps to corroborate diagnosis. These findings and a summary which includes the previously published cases of CBD show that CBD in most cases can be diagnosed intra vitam.
