うつ病の精神力学

The Psychodynamics of Depression

　I．はじめに

　うつ病の精神力学的研究の基礎を造つたのは，他の精神疾患の場合と同じく，Freudである。そこで最初にかれのうつ病学説を簡単に紹介し，ついでその後の研究者の説を概観し，最後に筆者の考察を付したいと思う。

　This paper proposes, after giving a brief resume of the psychoanalytic theories of depression, that the clinical picture of depression can be understood as the reaction to the loss of an illusory feeling of unity with others or the world. Such an illusory feeling of unity with one's environment is originally acquired as a defence against early frustration of infantile dependency need and subserves the formation of a compulsive personality which, when it breaks down under pressure, develops a depressive reaction. Two clinical cases are presented to illustrate the above hypothesis.
