There are several reasons this could be happening. First, it could be that it has a fungus, either on the leaves or on the roots. Another possibility is that it is getting too little or too much water. And yet another possibility is that it has a pest of some kind.
Check the roots and leaves carefully for signs of pests or damage. Make sure the soil is not too dry or too wet and it can't hurt to treat the plant with a fungicide.
