BCHE and dementia: Apart from testing for NOH, screening for AUDs/NSDs was based on participants’ self-reports, which may have varied according to their impact on quality of life, the patient’s cognitive state, etc. In particular, our results highlight a lower reporting of certain symptoms among subjects with dementia (compared to MCI) and among subjects taking cholinesterase inhibitors (who may have mixed dementia more frequently), suggesting a possible recall bias.
