Few public health problems have captured the attention of the biomedical and lay communities alike as has Alzheimer disease (AD). As the new millennium begins, it is becoming increasingly clear that a great many people will escape other major causes of mortality to reach the age when neurodegenerative diseases, particularly AD, become highly prevalent. To avoid an exacerbation of the personal and societal tragedy that AD already represents, clinicians and researchers must accurately define its cause and early pathogenesis and develop effective interventions, preferably agents that prevent the onset of symptoms. The study by Näslund et al¹ in this issue of THE JOURNAL provides compelling evidence that the accumulation of small protein fragments called amyloid -peptides (A) in brain regions subserving memory and cognition is a very early pathogenic event that precedes both neurological impairment and the development of the other proteinaceous lesion of AD, . . .
