Domain‐specific self‐ and informant‐reported cognitive complaints across the Alzheimer’s disease spectrum

A growing number of studies are currently investigating whether Subjective Cognitive Decline (SCD) may represent an early indicator of Alzheimer’s disease (AD). Due to the high frequency of amnestic AD dementia, SCD research is highly focused on episodic memory. Non‐amnestic complaints are less studied, although patients or their families often report difficulties in retrieving words, planning or spatial orientation, to name a few (e.g., Valech et al., 2018, J Alzheimers Dis). Furthermore, few studies have investigated which source of complaint is the most accurate. In this study, we aimed to measure how accurately self‐ and informant‐reported complaints in different cognitive domains can discriminate individuals along the AD continuum and controls.
