Likely causes
Poor Drainage
Most likelyHow to tell: The soil stays soggy and the base of the plant feels mushy. The roots may look dark and slimy.
What to do: Repot the plant into fresh, well draining soil. Trim away any black or mushy roots with sterilized shears before replanting.
Overwatering
PossibleHow to tell: The plant looks wilted despite the soil being constantly saturated.
What to do: Allow the top inch of soil to dry slightly between waterings. Ensure your pot has drainage holes so excess water can escape.

When to worry
If the roots are mostly black and mushy, the plant may be too far gone to save. If you see some healthy white roots, there is still hope.
Stopping it coming back
Always use a well draining potting mix and never let the plant sit in a saucer of standing water.
