Data are given as mean of right and left sides (SD)
In participants with dementia other than AD, SVD or Mixed, manual volumetry was performed in three MRI exams and FreeSurfer volumetry in 34 MRI exams
AD Alzheimer’s disease, CH Cognitively healthy, MCI Mild cognitive impairment, Mixed Mixed dementia, MTA Medial temporal lobe atrophy, SCI Subjective cognitive impairment, SVD Subcortical vascular dementia
