In seven cases of essential hypertension the following similarities were found by psychoanalytic investigation: (1) The prominance in every case of a dominating mother with submissiveness and oral dependence toward her, transferred in the cases of two men to their fathers; unsuccessful, nearly conscious rebellion against this submissiveness and chronic unexpressed rage at unsatisfied oral demands and against independent activity and work. (2) Marked inhibition of heterosexuality, although indulged to some extent, despite anxiety. (3) Intense, chronic, inhibited hostilities, not adequately repressed and bound, as for instance in cases of organized neurosis. (4) The hypertensive individuals were neither weak and dependent nor aggressively hostile but were blocked in both directions. During periods when either trend was satisfied, the blood pressure was markedly lower.
