AphasiaDx is an expert system that has been created to assist with the diagnosis of aphasia. It has been developed using Common Lisp, Common Lisp Object System, and a logic programming system Prolisp. As part of a larger neurodiagnostic system, Neurobridge, AphasiaDx has been programmed to diagnose Broca’s aphasia, Wernicke’s Aphasia, global aphasia, mixed transcortical aphasia, transcortical sensory aphasia, transcortical motor aphasia, and conduction aphasia. Benchmarks were developed and tested against our programmed rule base and confidence factors (CF) were accurately produced for the correct diagnosis. This expert diagnostic system can be utilized for medical problem solving as well as well as for educational purposes.
