Executive variant or frontal AD
- Executive dysfunction and behavioral symptoms (Salardini 2019)
- Shares overlaps with bvFTD, though frontal AD can be distinguished by: (Ljubenkov and Miller 2016)
- greater burden of parietal and mesial temporal atrophy
- greater degree of memory disturbance and executive dysfunction earlier in their course
- less severe behavioral disturbances
- FDG-PET may help distinguish areas of hypometabolism
- amygdaloid biomarkers provide most definitive diagnostic clarity
