We study the Dark Matter (DM) distribution in the inner Galactic Center region (< 100 pc) considering the extrapolation of a compilation of density profiles appearing in state-of-the-art N-body + Hydrodynamics simulations of Milky Way-like galaxies. We consider (i) the DM-spike induced by the presence of the supermassive black hole and (ii) the effects of the scattering off of the DM particles in the spike by bulge stars. Some of these cases can provide the flux enhancement required to explain the cut-off in the HESS J1745-290 gamma-ray spectra as TeVDM as well as the spatial tail reported by HESS II at angular scales < 0.54 degree towards Sgr A*.
