In this paper we explored patterns of frontal and temporal asymmetry in frontotemporal dementia (FTD) and tried to isolate clinical correlates associated with asymmetry or lack thereof. Volumes of frontal and temporal lobes, hippocampus and entorhinal cortex were measured using magnetic resonance imaging (MRI) in 10 patients with FTD. Age- and cranial size-specific values were computed through linear regression analysis (W-scores). A subgroup of 3 patients with symmetric frontal and temporal atrophy was identified. When compared to patients with asymmetric atrophy, the former had younger age at onset of the disease (p = 0.02), greater overall frontotemporal (p = 0.02) and greater entorhinal atrophy (p <0.04). Two of the three patients were apolipoprotein E ε4 carriers versus none of the asymmetric patients (p = 0.02). The lack of asymmetry in this small sample of FTD patients was associated with greater brain atrophy, younger age at onset, and presence of the ε4 allele of apolipoprotein E. The presence of the ε4 allele is consistent with the hypothesis of greater vulnerability of the brain in ε4 carriers.
