We consider Young's nonuniformly hyperbolic system (X, T, nu) where nu is the SRB measure corresponding to the system (X, T), and show that if the components of a Holder observable f: X -> a (d) are cohomologously independent, then f satisfies the multidimensional central limit theorem. Moreover if f is aperiodic, then f satisfies the local multidimensional central limit theorem.
