  We show some phenomenological implications for the dark matter problem of a
class of models with deflected anomaly mediated supersymmetry breaking in the
context of the MSSM. This scenario can be naturally embedded in a brane world
model with one compactified extra dimension. It turns out that in these models
the neutralino is still the LSP and so a good candidate as cold dark matter. We
found that the neutralino is quite a pure bino in almost all the parameter
space. Moreover we computed the thermal relic density and we found wide
cosmologically allowed regions for the neutralino.
