Dynamics of Neuropsychological Symptoms during the Training of Executive Functions in Neurological Patients

Executive function disorder rehabilitation in neurological patients is associated with many difficulties. We investigated the effectiveness of group training, proposed by B. Wilson et al., which has the model of frontal lobes functioning by D. T. Stuss as the theoretical background. The study participants were 16 patients with executive function disorder caused by TBI, strokes, and infections. The training was shortened from 9 weeks to 3 and adopted to the conditions of the rehabilitation centre where the study was held. The evaluation of training effectiveness was carried out by the methods of neuropsychological diagnostics proposed by A. R. Luria as well as standardized quantitative tests (CWIT test, Raven test, FAB) and questionnaires (EBIQ) aimed at assessing the state of executive functions and general well-being. In result positive trends, but not reaching the level of significance, were revealed in the performance of all evaluating methods, with the exception of "arithmetic problems" and "inhibitory control" as part of the FAB test. Statistically significant result was obtained concerning such tests as "counting", "analysis of story pictures", and index of total uncorrected errors in the CWIT test. Thus, the results of eventual assessment showed positive dynamic of executive functions state.
