Abstract

The invention provides improved agents and methods for treatment of diseases associated with amyloid deposits of Aβ in the brain of a patient. Such methods entail administering agents that induce a beneficial immunogenic response against the amyloid deposit. The methods are useful for prophylactic and therapeutic treatment of Alzheimer'"'"'s disease. Preferred agents including N-terminal fragments of Aβ and antibodies binding to the same.

Claims

1. A method of preventing or treating a disease associated with amyloid deposits of Aβ

in the brain of a patient, comprising administering to the patient an effective dosage of a polypeptide comprising an N-terminal segment of Aβ

, the segment beginning at residue 1-3 of Aβ and

ending at residues 7-11 of Aβ

.

33. A pharmaceutical composition comprising a polypeptide as defined in claim 1 and an adjuvant.
