How does drinking coffee impact Parkinson's disease?

It is not clear whether there are any benefits to drinking coffee for people who have already been diagnosed with Parkinson's. Most of the recent research that has come out about coffee has to do with its ability to reduce the risk of developing diseases such as Parkinson's. Once you have already developed Parkinson's, its benefits are debatable.

Provided it doesn't irritate your stomach, coffee is okay to drink, but you should talk to your physician about any symptoms associated with drinking caffeine (for some people, it can be a bladder irritant or make their tremor worse). Coffee can help if you suffer from daytime sleepiness, but consider having your last cup long before bedtime as caffeine later in the day can interfere with your sleep cycle if you're especially sensitive to it.  Or, choose decaffeinated coffee.
