With the increase of life expectancy, psychological writings about ageing have not developed as much as those concerning adults and children. It seemed to us interesting, fascinating and fruitful to think about this senescence period by restating the « somat/psyche » duality throughout the deterioration event. The use of a quantitative and qualitative methodology allows us to tackle the fall event as a traumatic experience according to physical data (fragile ou valid subject, somatic or psychomotor consequences…), temporal (since the last fall, moment of the fall, objective and subjective age of the fall…) and psychic (defenses set up, reminiscence, the work of getting old…) So we specifically looked at the turning point of this event in the context of expensive treatment of conflicts emerging at that time to discover obsessive defense mechanisms and primary maternal regression. In consequence, the development of psychological and psychoanalytical reasoning on the observation of the fall of the ageing subject can only be appreciated by not « falling » in the belief of a unique link of casuality, within an indistinguishable demographic class where age would be seen as an etiological factor. The use of quantitative and qualitative analysis of the discourse gives access to postfall reactive data but also to psychic treatment methods of the conflicts and affects which emerged from this event. We combined verbal communication with the drawing technique to get an insight of the mental images set in the historical narrative of memory. The fall is then exposed as an action, to mitigate the failure of the protective shield system and the capacities of development and connection to the narcissistic injury of senescence. However, it can also be appreciated as a coming back an elaborative resumption of attachment that leads to an inevitable end. It was then that "what is called a reason for living is also an excellent reason for dying" (Albert Camus). Indeed writings on the subject of the psychological deterioration of the ageing person are mainly studied in the context of the psychopathological or deficient process of the frail person in question, hospitalized without really taking into account the individual and collective complex alterations common to the process of ageing. We therefore concentrated on the psychic process of a valid old subject in order to glean more clinical reflections on the type of anxiety and object interaction. The TAT/SAT proposed concerning our study has established the psychic constitution of an internal model of an insecure relationship of the ageing, linked with an infringing relational experience with a failing and disappointing maternal object.
