    • The invention relates to a 2-(diaza-bicyclo-alkyl)-pyrimidone derivative represented by formula (I) or a salt thereof:
      wherein:

      R1 represents a hydrogen atom, a C 1-6 alkyl group or a halogen atom;
      R2 represents a hydrogen atom, a C 1-6 alkyl group optionally substituted by 1 to 4 substituents selected from a halogen atom, a hydroxyl group or a C 1-4 alkoxy group; a C 1-2 perhalogenated alkyl group, a benzyl group, a phenethyl group, a benzyloxycarbonyl group, a C 1-4 alkoxy carbonyl group, a benzene ring, a naphthalene ring, a quinoline ring, a phthalazine ring, a 5,6,7,8-tetrahydronaphthalene ring, a pyridine ring, an indole ring, a pyrrole ring, a thiophene ring, a benzenesulfonyl group, a benzoyl group, a pyridazine ring, a furan ring or an imidazole ring; the benzyl group, the phenethyl group, the benzyloxycarbonyl group, the benzenesulfonyl group, the benzoyl group and the rings being optionally substituted by 1 to 4 substituents selected from a C 1-6 alkyl group, a benzene ring, a halogen atom, a C 1-2 perhalogenated alkyl group, a C 1-3 halogenated alkyl group, a hydroxyl group, a C 1-4 alkoxy group, a nitro, a cyano, an amino, a C 1-6 monoalkylamino group or a C 2-10 dialkylamino group;
      R3 represents a 2, 4 or 5-pyrimidine ring optionally substituted by a C 1-4 alkyl group, C 1-4 alkoxy group or a halogen atom;
      R4 represents a C 1-4 alkyl group optionally substituted by a hydroxyl group, a C 1-4 alkoxy group or a halogen atom and n represents 1 or 2.

      The invention relates also to a medicament comprising the said derivative or a salt thereof as an active ingredient which is used for preventive and/or therapeutic treatment of a neurodegenerative disease caused by abnormal activity of GSK3β, such as Alzheimer disease.
