Cyclic amide derivatives defined by the formula: R1 - (CH2)n-Z (I) or a salt thereof are disclosed, in which R1 is a group derived from a substituted or unsubstituted cyclic amide compound, n is zero or an integer of 1 to 6 and Z is a group: Image in which R2 is an aryl, a halogen-substituted aryl, a cycloalkyl or a heterocyclic group, m is an integer of 1 or 2, R3 is hydrogen or a lower alkyl, R4 is an aryl or a halogen-substituted aryl, a cycloalkyl or a heterocyclic group, and p is an integer of 1 or 2, provided that when the cyclic amide compound is quinazolinone or quinazoline-dione, R2 aid R4 are neither aryl nor substituted aryl. The cyclic amide compounds are pharmacologically effective in the prevention and treatment of diseases due to insufficiency of the central choline functions.
