Neuropathological studies are reported in 111 cases from the Mariana Islands: 35 of amyotrophic lateral sclerosis (ALS), 47 of parkinsonism-dementia complex (PD) or parkinsonism; and 29 in whom neither ALS nor PD was clinically diagnosed (these served as controls for comparison). In addition to the pathology of classical ALS, neurofibrillary changes were widely distributed in all the Chamorro ALS cases from Guam. The substantia nigra was affected in all the ALS cases from Guam, in degrees varying from macroscopic atrophy to microscopic findings of scattered neurofibrillary changes in the pigmented neurons. The principal neuro-pathologic features in the Chamorro PD cases of Guam were essentially similar to those previously reported and consisted of specific localization of the degenerative changes and of widespread neurofibrillary lesions. Study of the spinal cord in these PD cases revealed that changes similar to those of ALS were found in approximately half of the cases. Furthermore, Intragangllonlc fibrillary changes were often observed in the spinal cord in the presence of a well-preserved neuronal population. Tissues of 5 of the 29 Chamorro adult "controls" demonstrated mild but definite histologic features common to the ALS-PD syndrome; the remaining 24 cases did not show these specific changes. The possible selective features in the control subjects are discussed. These observations in the Guam cases further support the previously proposed hypothesis that ALS and PD are related as members of a spectrum of a single disease entity: ALS-PD. The relationship of this syndrome to other diseases is discussed on the basis of neuropathological findings. The pathogenesls of neurofibrillary changes is considered as is the possible etiology of ALS-PD.
