If you're science savvy or willing to dive in and educate yourself, a number of websites let you follow research at the cutting edge.

• MEDLINE/PubMed is the NLM's database of summaries of biomedical research journal articles. A tutorial gets newcomers started in learning how to browse the database using key word searches. (If you're having trouble understanding medical and scientific jargon, MedlinePlus provides an online medical dictionary and encyclopedia.)
• Cochrane Reviews lets you search for free, plain-language summaries of scientific reviews that rigorously assess evidence for and against different Parkinson's disease therapies.
• WE MOVE, Worldwide Education and Awareness for Movement Disorders, is a nonprofit organization that has a research news service called E-MOVE, which summarizes fresh findings and news. You can sign up for e-mails about Parkinson's news.
• The Michael J. Fox Foundation provides much detail about the different investigations it's funding, with a searchable online database of research projects. Visit the website's MJFF Funding Portfolio section.

As promising as research results may seem, it's best to ask a neurologist or another medical expert for a realistic perspective on them. It's unlikely that you'll find a magic bullet to cure your loved onet by scouring the Web, but studies may reveal new insights into how to best manage the illness through available drugs, exercise, diet, or other interventions.
