This invention provides a method of inducing cognition enhancement in a mammal by administering to the mammal experiencing a cognition impairment an effective amount of a hydroxycycloalkanephenethyl amine compound of the following structural formula: ##STR1## in which A is a moiety of the formula ##STR2## wherein the dotted line represents optional unsaturation; R.sub.1 is hydrogen or alkyl; R.sub.2 is alkyl; R.sub.4 is hydrogen, alkyl, formyl, or alkanol; R.sub.5 and R.sub.6 are, independently, hydrogen, hydroxyl, alkyl, alkoxy, alkanoyloxy, cyano, nitro, alkylmercapto, amino, alkylamino, dialkylamino, alkanamido, halo, trifluoromethyl, or taken together, methylene dioxy; R.sub.7 is hydrogen or alkyl; and n is 0, 1, 2, 3, or 4; or a pharmaceutically acceptable salt thereof.

Venlafaxine in the inducement of cognition enhancement

Compounds of the formula: ##STR1## in which m is one of the integers 1, 2 or 3; n is one of the integers 0, 1 or 2; o is one of the integers 0, 1 or 2; R.sub.1 and R.sub.2 are, independently, hydrogen, hydroxyl, alkyl, alkoxy, alkanoyloxy, trifluoromethyl, halo, or, when taken together, 3,4-methylenedioxy; R.sub.3 is alkyl, ##STR2## where R.sub.4 and R.sub.5 are, independently, hydrogen, hydroxyl, alkyl, alkoxy, alkanoyloxy, halo or trifluoromethyl; and R.sub.6 is hydrogen or halo; or a pharmaceutically acceptable salt thereof.

Substituted 1-(aralkyl-piperazinoalkyl) cycloalkanols

This application discloses certain substituted phenylacetamides of the formula: ##STR1## in which the dotted line represents optional unsaturation, R.sub.1 is alkyl;

Substituted phenylacetamides

The compounds ##STR1## in which R.sup.1 is 3-hydroxy, 4-hydroxy, 3-methoxy, 4-methoxy or 3,4-methylenedioxy; n is 1 or 2; and R.sup.2 is ##STR2## where R.sup.3 is hydrogen, alkoxy of 1 to 6 carbon atoms, halo or trifluoromethyl; or a pharmaceutically acceptable salt thereof possess anxiolytic and antidepressant activity and are useful in treating psychiatric disorders involving anxiety and/or depression.
