Normal aging is also accompanied by a memory decline associated with a decrease in attentional resources (e.g., Blanchet et al., 2006). Our objective is to examine how executive dysfunction in older adults with MTBI may affect memory performance. We administered a memory paradigm manipulating the attention level [full attention (FA), divided attention (DA)] during learning, as well as the recall modes (free, cued, recognition) to 6 older adults with MTBI (M = 66 yrs) and 5 matched controls (M = 63.5 yrs). Persons with MTBI and controls did not differ on the number of recalled words after learning in FA. In contrast, after DA encoding, participants with MTBI reported fewer words for each recall mode. They also reported more memory problems in their daily activities as assessed by the Memory Self-Evaluation Questionnaire. Persons’ with MTBI learning seems thus particularly affected by the presence of a secondary task. These memory impairments may explain their memory complaints in daily life. These preliminary data need to be confirmed on larger samples. Conference: The 20th Annual Rotman Research Institute Conference, The frontal lobes, Toronto, Canada, 22 Mar - 26 Mar, 2010.
