Novità parkinson

Buongiorno,
sono iscritta alla fondazione di Michael J. Fox sulla ricerca contro il Parkinson e regolarmente ricevo le loro newsletter.
Qualche giorno fa' ho ricevuto delle news molto importanti, ma purtroppo il mio inglese non è ottimo ed essendoci termini medici non sono sicura di avere capito bene, mi potreste essere d' aiuto?

" JAMES SURMEIER, PhD, TALKS TO MJFF ABOUT FDA-APPROVED HIGH BLOOD PRESSURE MEDICATION AS A TREATMENT FOR PD (Parkinson's Disease)

In February, news media reported recent findings that calcium channel blockers - widely used, FDA-approved high blood pressure medications - seem to reduce the risk of Parkinson´s disease. To put this breaking news in context, the Foundation spoke to D. James Surmeier, PhD, of Northwestern University. Dr. Surmeier received a $75,000 Rapid Response Innovation Award from MJFF to study isradipine, one such drug. Here´s an excerpt of what he had to say:

MJFF: How may these drugs be protecting dopamine neurons from the cell death seen in Parkinson´s disease?

DJS: Calcium channels are found in many cells of the body, including dopamine neurons - the brain cells that die in Parkinson´s disease...Dopamine neurons rely heavily on calcium channels to maintain their normal level of activity. We think that the cells´ reliance on calcium to drive this activity creates a lot of `wear and tear´ on dopamine neurons - aging them more rapidly than other neurons and making them vulnerable to genetic mutations and other stressors, like environmental toxins.
MJFF: If you are a person living with PD and high blood pressure, should you ask your doctor to prescribe isradipine or another calcium channel blocker right away?
DJS: We are hearing anecdotally that many people with Parkinson´s disease are asking their physicians to be switched to a calcium channel blocker from another class of high blood pressure drug, such as beta blockers. In general this is a perfectly reasonable strategy as long as the physician agrees to it and the patient is carefully monitored.
I would note, however, that more research is needed...The study published earlier this month was a retrospective one... A prospective study is critical to knowing whether calcium channel blockers actually prevent or slow PD. "

Da quel che ho capito alcuni farmaci per l' alta pressione sanguigna potrebbero essere d' aiuto contro il Parkinson?
Grazie in anticipo.
