The concurrence of multiple sclerosis and amyotrophic lateral sclerosis.
We report the clinical and pathological findings of the unusual combination of two idiopathic central nervous system diseases, multiple sclerosis and amyotrophic lateral sclerosis in a 56 year old physician with a twenty-seven year history of a disease initially characterized by relapses and remissions, followed by an eight year quiescent period. During the last year of life there was rapid deterioration with development of generalized weakness, atrophy, weight loss and fasciculations of body and tongue, and associated difficulty with swallowing and sudden respiratory failure. The autopsy confirmed characteristic "burned out" plaques of multiple sclerosis and anterior horn cell and axonal degeneration of amyotrophic lateral sclerosis.
