The previous study by Gertje et al13 included only CN (67.5%) and MCI (22.5%) individuals, but not patients with dementia, to analyze the relationship between EPVS and CSF tau levels, while we included individuals with a diverse cognitive spectrum (CN [41.7%], MCI [27.6%], and Alzheimer's disease dementia [30.7%]). The gene discussed is MAPT; the disease is dementia.
