Original abstract
Two cases of striato-nigral degeneration are reported. In case 1 the female patient showed a Parkinson syndrome, cardiac arrhythmias and vasomotor disturbances. Morphologically mainly the putamen and substantia nigra revealed severe atrophic changes according to the restricted form of striato-nigral degeneration (SND). In case 2 there was a disorder of the upper and lower motor neuron in a female patient. Morphologically this case was an example of a multisystem atrophy with changes in the striato-nigral, olivo-ponto-cerebellar systems and spinal motor and autonomic neurons. These cases demonstrate the variability of the striato-nigral degenerations which are met with in two forms: a "pure" form as in case one and as a part of multisystem atrophies. This is underlined in a review of 69 literature cases, which also shows that SND, Shy-Drager syndrome and olivo-ponto-cerebellar atrophy represent very probably different varieties of one and the same degenerative process.
