Cherry-red spot myoclonus syndrome (type I sialidosis).
The authors report the sequence of the clinical symptoms in type I sialidosis or cherry-red spot myoclonus syndrome, derived from the cases personally observed and from the literature. They also report neuropathological and neurochemical data. A serial EEG study in a case shows the tendency to a progressive deregulation of cerebral electric activity. Therapeutic attempts to reduce myoclonus, which is one of the more disabling symptoms in this syndrome, are described.
