A method comprising administering a sulfonamide derivative to a patient requiring activation of glutamate receptors, the sulfonamide derivative represented by the formula ##STR1## wherein A is a napthyl group, a pyridyl group, a phenyl group, a phenyl group substituted by 1 to 5 members selected from the group consisting of a halogen atom, an alkyl group having 1 to 40 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a nitro group, and an acetamido group, or an alkyl group having 1 to 20 carbon atoms; B is an alkylene group having 1 to 3 carbon atoms, a group of --OCH.sub.2 -- or a group of --CH.dbd.CH--; X and Y are the same or different, and are each a hydrogen atom or a fluorine atom; R is a carboxy group, an alkoxycarbonyl group having 2 to 5 carbon atoms, a hydroxymethyl group or a group of ##STR2## wherein R.sub.1 is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; and R.sub.2 is a hydrogen atom, a hydroxyl group, an alkyl group having 1 to 3 carbon atoms, a carboxymethyl group or an alkoxycarbonylmethyl group having 3 to 6 carbon atoms; m is an integer from 0 to 2; and n is an integer from 0 to 3, or an pharmaceutically acceptable salt thereof, as an effective ingredient. The agonist is efficacious in the medical treatment of nerve degenerative disorders.
