  The Langevin dynamics of a $d$-dimensional mean spherical model with
competing interactions along $m\leq d$ directions of a hypercubic lattice is
analysed. After a quench at high temperatures, the dynamical behaviour is
characterized by two distinct time scales associated with stationary and aging
regimes. The asymptotic expressions for the autocorrelation and response
functions, in supercritical, critical, and subcritical cases, were calculated.
Aging effects, which are known to be present in the ferromagnetic version of
this model system, are not affected by the introduction of competing
interactions.
