Do aetiology, age and cogntive reserve affect executive performance?
Background: The behavioral effect of frontal lesions may be influenced by confounding factors such as aetiology, age and cogntive reserve. Yet no studies have investigated their effects on patients with focal lesions. Objective: Is the grouping of patients with frontal lesions caused by stroke or tumours methodologically appropriate; does age affect cognitive performance, can cognitive reserve protect against cognitive impairment? Patients and Methods/Material and Methods: Cognitive performance was compared across a large sample of frontal patients with stroke, high or low grade tumour, or meningioma. The effect of age, education and NART IQ on the cognitive performance of patients with foc…
Cognitive Reserve Proxies Do Not Differentially Account for Cognitive Performance in Patients with Focal Frontal and Non-Frontal Lesions
AbstractObjective:Cognitive reserve (CR) suggests that premorbid efficacy, aptitude, and flexibility of cognitive processing can aid the brain’s ability to cope with change or damage. Our previous work has shown that age and literacy attainment predict the cognitive performance of frontal patients on frontal-executive tests. However, it remains unknown whether CR also predicts the cognitive performance of non-frontal patients.Method:We investigated the independent effect of a CR proxy, National Adult Reading Test (NART) IQ, as well as age and lesion group (frontal vs. non-frontal) on measures of executive function, intelligence, processing speed, and naming in 166 patients with focal, unila…
