MRI–magnetic resonance imaging; bvFTD–behavioural variant of frontotemporal dementia; PSP–progressive supranuclear paralysis; ALS–amyotrophic lateral sclerosis; AD–Alzheimer’s disease. Mild frontal atrophy asymmetry that could not be considered in the visual scale scores was noted in Cases 1 and 2.
