EEA1 and Alzheimer disease: There was a significant difference between the scores for EEA‐1 immunostaining in FTLD (collectively), AD and healthy controls for area CA4 of the hippocampus (H = 7.7, P = 0.021), DG (H = 10.9, P = 0.004) or Tcx (H = 8.4, P = 0.015), with the scores for FTLD cases being significantly higher than those for control cases in all the three regions (CA4, P = 0.027; DG, P = 0.014 and Tcx, P = 0.015), but these did not differ from AD cases, which in turn did not differ from controls.
