Étude du vieillissement normal des fonctions frontales : impact sur l’autonomie et la qualité de vie

Abstract : Starting from the “frontal lobe hypothesis of cognitive aging” (West, 1996), the main objective of this work is to study frontal lobe functions (executive control, decision making,energization, metacognition; Stuss, 2008) and their possible associations with levels of autonomy and quality of life in normal aging. Forty young adults (26±5years), forty old adults (68,7±3,7 years) and thirty very old adults (83,4±3,5 years) participated to our study.These healthy subjects didn’t show any depressive/anxious symptoms and global cognitive decline, which are frequently observed in pathologic alaging. They have a good level of autonomy and general satisfaction of life. A number of frontal lobe abilities seem to decrease after 65 years old (flexibility,energization, explicit decision-making, theory of mind,detection of cooperative and deceptive situations).Other functions decline after 80 years old (verbalfluency, episodic memory, naming, inhibition, implicit decision-making). Reading, immediate recall, realization of spontaneous flexibility and simple reaction time tasks are preserved with aging. Self-consciousness seems to depend on individuals’ age. We have described three different clusters of the frontal functioning for each group of participants, showing the existence of animportant intragroup variability. Old adults’ level of autonomy seems to be associated with the executive control, old adults’ quality of life correlated with the energization and metacognitive functions. These resultsconfirm in part our hypothesis and support the development of multidimensional cognitive training programs, which could impact old adults’ personal sphere.
