Like many older guys, I wear glasses. At my age, I’m helpless without them!

Father Time can really do a number on our vision as time goes by.

But it’s not just about reading the newspaper or a menu in a dark restaurant.

Because what’s going on in our eyes can tell us a lot about what’s going on in our brains!

Recently, I shared with you that certain changes in your retinas -- the light-sensitive nerve cells that line the back of your eyes -- may be an early sign of Alzheimer's disease.

And according to a new study, changes to your retina may also be one of the first symptoms of another neurodegenerative disease.

It’s one that I've lived with for over a dozen years: Parkinson’s.

South Korean researchers found that the retinas of Parkinson's patients were significantly thinner than those in group of healthy controls.

Not only that, but the Parkinson's patients with the THINNEST retinas also had the MOST SEVERE motor symptoms.

Fortunately, I’ve got a way to naturally support your vision AND your mobility – and it’ll all make sense once you understand the underlying mechanism behind why eye changes may lead to Parkinson’s.

It looks like the two are connected by the brain chemical dopamine.

You see, we've known for a while that the tremors and stiffness of Parkinson's are linked to the loss of neurons in your brain that produce dopamine.

And since dopamine can ALSO come from the nerve cells in your retina, the theory is that retinal cell death causes the same thing as when your dopamine-producing brain cells die off.

Only, this is a red flag that may start waving WAY before other noticeable changes.

Typically, Parkinson's is diagnosed based on a neurological exam -- and the doc might even scan your brain to take a gander at your dopamine system.

But a study last year found that Parkinson's vision changes may begin more than a DECADE before any motor problems show up!

So, the new study is a good reminder to get your eyes checked out regularly -- not only to screen for eye diseases, but also to gain "insight" into your general health.

After all, your eyes aren't just a window into what's going on in your brain.

Early signs of heart disease… diabetes… and even cancerous tumors often show up in your eyes.

And it just so happens that many of the same healthy habits that protect your eyes from disease also help shield your brain from neurodegenerative diseases like Parkinson's.

Natural anti-inflammatories like curcumin -- which is found in turmeric, a yellow spice used in ballpark mustard and Indian curries -- can reduce oxidative stress and damage in your retinas.

It can ALSO help snuff out the flames in your gray matter that have been linked to Parkinson's.

And since both Parkinson's and eye diseases like macular degeneration have been linked to high blood sugar, slashing sugar from your diet can protect both your brain and eye health.
