The use of a genetic method to down-regulate RBO/EFR3/EFR3A/EFR3B proteins, TTC7 protein or PI4KIIIα enzyme protein which interacts with RBO/EFR3/EFR3A/EFR3B proteins and TTC7 protein, or the use of a drug to inhibit PI4KIIIα protein kinase activity reduces the accumulation of Aβ42 within neurons and age-dependent synaptic transmission failure and other obstacles in a fruit fly AD model, and obtains an effect of improving the learning and memory abilities of AD model mice. Provided is a method for using an RBO/EFR3/EFR3A/EFR3B inhibitor, a TTC7 inhibitor and a PI4KIIIα inhibitor to treat Alzheimer's disease. Also provided is a method for screening a drug treating Alzheimer's disease by whether Aβ secretion by nerve cells is promoted or not.
