Objective: Poor judgment is a hallmark of FTD, and sometimes occurs in AD. There are very few objective tests of judgment. In our clinic, we use the Test of Practical Judgment (TOPJ). Given that impaired judgment can occur in FTD and AD; the current study assesses group differences between patients with FTD and AD on the TOPJ. Method: The TOPJ is an objective measure of everyday judgment. Patients have a hypothetical scenario presented to them and they are asked to explain what they would do in that situation. The TOPJ was administered in a clinical setting during a standardized neuropsychology battery. At the time of testing the patients did not have a clinical diagnosis. Later, nine patients diagnosed with probable FTD were matched with nine patients with suspected AD based on overall MOCA scores. Results: Correlation analysis was conducted to compare the scores of the FTD patients and AD patients. FTD patients had a mean score of 15.89, AD patients had a mean score of 20.89 (cut off for “normal” scores is 19.4). It was found that a statistically significant difference exists in the TOPJ scores of the two groups (p = .027). Conclusion(s): The results demonstrate that although judgment is affected in both groups poor decision making, as measured by the TOPJ, is more pronounced in patients with FTD. Given that poor judgment is a known feature of FTD, this suggests that the TOPJ might represent a useful way to assess judgment objectively.
