Differential Diagnosis of dementia and depression requires expertise. DAD is a computer-aided expert system, which uses the patient's behavioural, cognitive, emotional symptoms; and results of neuropsychological assessment to diagnose depression or dementia. Built in Turbo Prolog, it uses depth first search method with backward search strategy. DAD's knowledge base has three data bases. Problem is represented with the problem reduction method using four modules. Results from the four modules are combined to give a final outcome which is then compared with facts in the knowledge base. DAD diagnoses the case on the basis of this match. DAD was validated on four patients' records. DAD's diagnosis coincided with the treating team's in each case.
