  Cosmology of ELKO and Lorentz Invariant NSS has been investigated using
dynamical system method starting from the proposal of Boehmer et al
[arXiv:1003.3858]. Some different results have been obtained by a different
approach. The exact solutions described by fixed points of the dynamical system
and their stability have been discussed. Some stable solutions corresponding to
de Sitter universes have been obtained.
