Can this plant be brought indoors for the winter? Is it to be treated the same as Mandevilla?

Yes, these are pretty much the same thing so treat them as such. Bring the plant indoors prior to your frist frost and allow it to go dormant. It will only need watering once a month during dormancy to keep the plant from drying out completely. Once spring returns and new growth begins, you can move it back outdoors (after threat of frost) and care as usual.
