frequency (t 1⁄4 2.8; p < .05). Conclusions: Although recognition memory is used as a key neuropsychological variable in differentiating FTD and AD, recognition discriminability can deteriorate at the earliest stages of FTD. The primary recognition error type (semantic commissions) and increased lexical frequency on semantic fluency, alongside the previously established pattern of verbal fluency (semantic < phonemic; Cheran et al., 2018), suggest that recognition deficiencies in FTD may stem from compromised semantic networks rather than memory or executive skills. While future work needs to compare FTD and AD directly, qualitative characterization of recognition errors may be useful in this differential diagnosis.
