USING MACHINE LEARNING METHODS WITH ELECTRONIC MEDICAL RECORDS: STUDY OF REHABILITATION PROFILES IN ACQUIRED BRAIN INJURY

The goal of this research project was to illustrate the utility of machine learning analyses in generating differential rehabilitation profiles for acquired brain injury groups using data from Electronic Medical Records (EMRs). Specifically, we focused on traumatic brain injury (TBI) given its complexity and importance as a major health issue. In this context, we compared TBI to patients with nonvascular etiologies (non-TBI) and vascular etiologies (stroke). As expected, the logistic regression classifier showed that younger adults and males are more likely to sustain a TBI. The decision-tree classifier suggested that of all comorbidities across TBI and non-TBI, intracranial injury followed by lung contusion, best distinguished TBI, while obstructive hydrocephalus was the weakest classifier.

ACTING INTERVENTION FOR OLDER ADULTS

The goal of this research project is to further characterize the behavioral and brain changes associated with participating in an intervention that involves learning a fundamental skill in acting called 'active experiencing'. Active experiencing involves a complete immersion - mentally, emotionally, and physiologically - into the scene and characters.  This aspect of acting is believed to be the key ingredient for positive changes in memory performance and quality of life in elderly adults . The current experiment was therefore designed to test the effects of acting classes that involve active experiencing [against a class that involves learning about the art of acting], and to specifically extend previous work by using structural and functional brain imaging to understand brain plasticity that underly any behavioral benefits. Currently, I am exploring brain network changes due to the intervention using graph theory, as well as using a functional MRI task called the AX-CPT.
