Brief Summary:
In a worldwide context of accelerated demographic aging, traumatic brain injury (TBI) in older adults has become a public health problem. TBI incidence grows following an exponential curve as people get older, increasing the occurrence of TBI in ageing individuals. Rehabilitation programs used in clinical settings have generally been developed for younger adults, and their efficacy with older adults who sustain a TBI has not been evaluated. The investigators have tailored a modular cognitive rehabilitation program for individuals who sustain a TBI in older adulthood, the Cognitive Enrichment Program (CEP), by adapting approaches which have shown to be effective in normal ageing and with other neurological conditions. The aim of the study is to evaluate the effectiveness of the CEP in adults having sustained a TBI during later adulthood. Specific objectives are to evaluate the effectiveness on memory, executive functions, psychological well-being and daily life activities using psychometric tests, self-reported questionnaires, and daily life-like tasks. The investigators hypothesize that memory and executive functions training included in the CEP will result in an improvement in both psychometric and self-reported scores in a trained group of older individuals with TBI, whereas this will not be the case for a comparable TBI group who did not receive the CEP intervention.

Detailed Description:
This study aims to evaluate the impact of a multimodal cognitive intervention, the Cognitive Enrichment Program (CEP), on episodic memory, executive functions, psychological well-being and daily life activities in traumatic brain injured (TBI) older adults, as compared to an active control group that receives only usual care in the form of holistic rehabilitation. The experimental design is a semi-randomized, controlled, before-after study with blinded outcome measurement. French-speaking participants aged 55 years or older and having sustained a mild, moderate or severe TBI at least 6 months before enrollment, were recruited by clinical coordinators from one hospital and from two outpatient interdisciplinary rehabilitation centres. The CEP consists of three intervention modules, Introduction and self-awareness, Attention and Memory, and Executive functions, which were conducted with groups of 5 participants, in 90-minute sessions, twice weekly, during 12 weeks. The CEP was conducted by an experienced clinical neuropsychologist. Assessments of intervention effects were performed by trained evaluators, who were blinded to group assignment of participants, in two separate sessions lasting about 90 minutes each. There were three assessment time-points: baseline (pre-intervention - T0); 14-weeks (post-intervention - T1); 6-months post-intervention (follow-up - T2). Primary outcome measures (neuropsychological and self-report) were chosen to measure targeted effects of the CEP and generalization measures (self-report) were used to evaluate broader effects of the intervention. Control measures were also used to control for spontaneous recovery.

Arm Intervention/treatment
Experimental: CEP intervention
Cognitive Enrichment Program (CEP) : tailored for individuals who sustain a TBI in later adulthood. The CEP is a 12-week multimodal intervention structured into three modules designed to simultaneously address cognitive problems resulting from TBI, as well as age-related cognitive issues in the following domains: self-awareness, attention and memory, and executive functions.
Behavioral: Cognitive Enrichment Program (CEP)
Multimodal cognitive rehabilitation program for individuals having sustained a traumatic brain injury during older adulthood

No Intervention: Usual care
Usual care : interventions within a holistic interdisciplinary rehabilitation program focused on resuming daily activities and social roles, if needed, as determined by treating physician; does not include any form of cognitive rehabilitation.
