Research Summary

"Exploring Ways to Restore Cognitive and Work Capacity" is our mission. Our goal is to restore functional capacity to people with disabling psychiatric conditions. We are particularly interested in vocational rehabilitation and neurocognitive rehabilitation and have tested interventions that can augment current best practices. Our work suggests that providing patients with on-going, specific feedback about their cognitive and work performance can improve vocational outcomes. Based on models of neuroplasticity, we have tested the use of computer-based cognitive exercises of attention, memory, language and executive functioning. We have found that such training can result in normal levels of task performance, improved neuropsychological test performance, and better functioning on the job. We have found that cognitive training combined with work therapy leads to greater productivity and when combined with supported employment leads to higher rates of competitive employment, especially for those with the poorest initial community functioning.

Evidence linking cognitive training to neuroplastic changes comes from pre-post fMRI studies that show improved cognitive efficiency on working memory tasks. Other methods being explored include social information processing groups, a CBT approach to negative cognitions regarding return to work, using D'serine as a cognitive enhancer to boost new learning in conjunction with cognitive training, and using motivation enhancing strategies. While most of our work has been with schizophrenia, we are now applying cognitive remediation approaches to patients in initial stages of substance abuse treatment and early stage Alzheimer's disease. Under development are new cognitive training software, simulated job interview training, and psychophysiological approaches.
