  The present work investigates the possibility that both dark matter and the
anomalous magnetic moment of the muon may be explained within the context of
the inverse seesaw extended Next-to-Minimal Supersymmetric Standard Model
(ISS-NMSSM). In ISS-NMSSM, the newly introduced Higgs-neutrino Yukawa coupling
$Y_\nu$ provides additional Higgsino-sneutrino loop contribution to
$(g-2)_{\mu}$. If the deviation between the experimental observations and the
Standard Model predictions of the anomalous muon magnetic moment is confirmed
by the further experimental and theoretical studies, it can be explained
naturally within the ISS-NMSSM framework without conflicting with the current
stringent limits on the direct detection of dark matter and Large Hadron
Collider searches.
