Need more info. How long have you had the plant?

Have you checked for spider mites? This will cause new leaves to die
immediately. Difficult to control in dracaena as they lay eggs in the apical
buds - which is what it sounds like if your new leaves are dying. If you do
have spider mites (or any other pest) a dilute mixture of rubbing alcohol,
garlic and dishsoap sprayed on the entire plant will control this. After
spraying with this solution, wipe each leaf and then follow with a spray of
water. If you have alcohol in the mixture, do not leave it on the leaves as
it will prevent the stomata from properly functioning.

Also a 20 change in temperature coupled with change in light will affect any
houseplant negatively. These moves should be done slowly to avoid shock.
Draceanas can be propagated by air layering to generate several new plants -
dependant on how tall the stalk is. Alternately (and perhaps drasticly you
can cut the entire top off the plant - ensuring that there is at least one
growth bud left on the stem.
For all of the above there are many sites that will provide background info
and suggestions.

I have a dracaena marginata. Normally, it had long slender green leaves
with maroon edges.

I had it in a low-light living room and it didn't seem to be doing to
well to me. It's leaves were drooping and there were quite a few red,
dying leaves. Also, it had fewer leaves than healthier ones I've seen. I
moved it to another room that gets a good amount of indirect light from
the southwest. In the past few days, it's been about 20 degrees hotter
than usual and brighter than usual. Now the draecana is doing worse. It
has even fewer leaves and a lot are getting yellow, than brown-red and
dying. The new leaves that sprout out of the top are dying right away.

I water this plant whenever the top inch of soil is dry.

What can I do to improve the health of this plant? Is it having a hard
time adapting to more light? Is it having a hard time dealing with the
changing temperature (90 rather than 70)? Too much water? Too little
water?

Also, when does a dracaena marginata get to the point where it no longer
can be salvaged? How many leaves does it need to stay alive? Can it come
back?

Thanks
