Although there exist different approaches to understand old people and ageing, the plainest psychical reality of ageing resides in the psychoanalytic field of exploration. Also, The Rorschach test being the foremost, projective instruments used in clinic help us discover the mental tendencies of old people in the light of psychoanalysis. In this article, it is mentioned that the old age is a period of psychical transformation, both in narcisistic and oedipal respects; and -starting especially from François Villa's approach- it is insisted upon the idea that ageing is a gain towards maintaining the life. In this regard, losses and gains of the old age are considered together; these processes are sought to be explained in the light of Freudian metapsychology over the mechanisms of mourning and melancholia. Later, the question is stayed on of how these transformations show themselves in The Rorschach test; and differences are touched upon between responses old individuals and those of younger adults. Lastly, how the psychical functionings of old people affected by Alzheimer disease show themselves in The Rorschach test is mentioned.
