Effect of the electron screening on the alpha decay rate of typical nuclei is considered. To this end, the adiabatical approach is exploited, which consecutively takes into account the adiabaticity of the motion of the alpha particle through the shells. The effect is found to be of the order of one tenth to one hundredth of a percent for the considered representative nuclei. The prospects of an experimental study of the effect aimed at search for the dynamics of $\alpha$ decay are discussed. It is suggested that presence of a muon in the orbit in the muonic atoms should have much stronger effect on the $\alpha$ decay rate than the effect of removing the electron shell.
