ALZ-50 is a monoclonal antibody that recognizes a protein of apparent molecular mass 68 kilodaltons (A68). The protein is present in the brains of patients with Alzheimer disease but is not detectable in normal adult brain tissue. We now report that ALZ-50-reactive neurons are found in normal fetal and neonatal human brain and in brain tissue from neonatal individuals with Down syndrome. Reactive neurons decrease sharply in number after age 2 and reappear in older individuals with Down syndrome and in patients with Alzheimer disease.
The authors describe the use of gabapentin in the treatment of 4 outpatients with dementia-associated agitation. On the basis of clinical case reports and the Overt Agitation Severity Scale, all 4 patients had reduced agitation with gabapentin. Three of 4 patients were successfully titrated to a full dose of 2,400mg/day. These findings suggest a possible role for gabapentin in the behavioral management of patients with dementia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
