BIN1 was reduced by 87% (p=0.007) in sporadic AD compared to non-dementia controls, but BIN1 in sporadic AD did not correlate with soluble Aβ (rs=-0.084, p=0.698), insoluble Aβ (rs=0.237, p=0.269), Aβ plaque load (rs=0.063, p=0.771) or phospho-tau load (rs=-0.160, p=0.489). Here, BIN1 is linked to dementia.
