Neural correlates of recognition and naming of famous persons and landmarks: A special role for the left anterior temporal lobe.

The anterior temporal lobes (ATLs) have been shown to be crucial for recognition and naming of unique entities such as persons and places. In this chapter, we review previous research that identified the neural underpinnings of these processes, and discuss the convergence zone theory of conceptual knowledge and proper name retrieval. Lesion-deficit and neuroimaging studies have found that the temporal poles are essential for recognition and naming of unique persons and places. Research has shown laterality, in that the right anterior temporal pole is specialized for recognition and the left for naming. Here, we analyzed recognition and naming of persons and landmarks in a large neurologic sample (N=244) using the Iowa Famous Faces and Famous Landmarks tests. For both categories, education had a significant effect on recognition and naming performances, but age and gender did not. Lesion-symptom maps revealed lower naming scores for both Faces and Landmarks associated with lesions to the anterior and mesial left temporal lobe. Lower recognition scores were also linked to left temporal lobe damage, possibly due to the method we used for measuring recognition (verbally based). Overall, the results demonstrate the importance of the temporal lobes for recognition and naming of unique persons and places.

The Association of Rehospitalization With Participation 5 Years After Traumatic Brain Injury.

OBJECTIVE: To determine whether rehospitalization during the first 2 years after moderate to severe traumatic brain injury (TBI) is associated with poor participation at 5 years post-TBI, after controlling for demographic and severity factors. SETTING: TBI Model Systems Program. PARTICIPANTS: Community-dwelling individuals with TBI, 16 years or older (n = 1940). DESIGN: Retrospective data analysis of a multicenter prospective study. MAIN MEASURES: Participation Assessment with Recombined Tools-Objective (PART-O). RESULTS: After controlling for demographic and severity factors, a general linear model indicated that rehospitalization status (ie, never rehospitalized during years 1 and 2, rehospitalized either during year 1 or 2, or rehospitalized during both years 1 and 2) predicted less participation at 5 years post-TBI (P = .0353). The PART-O scores were in the hypothesized direction, with the lowest covariate-adjusted mean participation score found for the group with rehospitalizations during both years and the highest covariate-adjusted mean participation score found in the group with no rehospitalizations. Examining total number of rehospitalizations during years 1 and 2, rather than rehospitalization status, yielded analogous results (P = .0148). CONCLUSIONS: This study suggests that rehospitalization in the first 2 years after TBI is negatively associated with participation at 5 years after injury. Since participation is considered a key indicator of successful TBI rehabilitation, minimizing the need for rehospitalizations and promoting health in the community setting should be a priority of postacute care for individuals with TBI.

Examining Driving and Participation 5 Years After Traumatic Brain Injury.

Participation is often considered a primary goal of traumatic brain injury (TBI) rehabilitation, but little is known about the influence of driving on participation after TBI. The objective of this study was to examine the independent contribution of driving status to participation at 5 years post TBI, after controlling for demographic, psychosocial, and functional factors. Participants ( N = 2,456) were community-dwelling individuals with moderate to severe TBI, age 18 to 65 at time of injury, and enrolled in the TBI Model Systems (TBIMS) National Database (NDB). Hierarchical linear regressions for the dependent variable of participation at 5 years post TBI were performed. Findings showed that driving was a highly significant independent predictor of participation and was a stronger relative predictor of participation than FIM® Cognitive, FIM® Motor, and depression. The independent contribution of driving to participation suggests the need to develop evidenced-based occupational therapy assessments and interventions that facilitate safe engagement in the occupation of driving to address the long-term goal of improved participation.

Predicting the Trajectory of Participation After Traumatic Brain Injury: A Longitudinal Analysis.

OBJECTIVE: To identify factors that predict trajectories of participation over the first 5 years after moderate to severe traumatic brain injury (TBI). SETTING: TBI Model System Programs. PARTICIPANTS: Community-dwelling individuals with TBI, 16 years of age or older (n = 1947). DESIGN: Secondary analysis of a prospective, nonrandomly sampled, longitudinal data registry. MAIN MEASURES: Participation Assessment with Recombined Tools-Objective (PART-O). RESULTS: Age at injury and FIM Motor score predicted trajectory of participation over the first 5 years after moderate to severe TBI. Older age predicted generally worse participation overall as well as progressively worsening participation over time. Higher FIM Motor raised the predicted participation values, although it reduced the rate of improvement in participation scores over time. FIM Cognitive scores, race, depression, years of education, and living setting did not predict trajectory but did significantly influence participation consistently at all time points. CONCLUSION: The trajectories of participation over the first 5 years after TBI can be predicted by age at injury and FIM Motor scores. These findings may enhance the ability of rehabilitation professionals to identify individuals at risk for poor participation after TBI and develop targeted interventions for optimizing involvement in life activities.
