Method of treatment of affections related to a disturbance of the intra and extra cellular movements of calcium at the cerebral level, which comprises administering an aromatic aminoalkoxy derivative of formula (I) or a pharmaceutically acceptable salt thereof: ##STR1## in which A represents a chain having any of the following structures: ##STR2## Ar represents a group of structure: ##STR3## n takes the value 1 or 2 when R is different from H; `m takes the value 3.

Use of aromatic aminoalkoxy derivatives for the treatment of troubles of

New aromatic derivatives having an activity antagonistic to calcium and corresponding to formula: ##STR1## in which: A represents a chain having any one of the following structures: ##STR2## Ar represents a group of structure: ##STR3## n takes the value 1 or 2 when R is different from H; m takes the value 2 or 3.
