Are the Eyes Important in Finding Early Alzheimer’s Disease?

arztsamui fdpAlzheimer’s Disease is a terrible malady of the mind that affects the brain, memory, thinking and behavior. Statistics show that more than five million Americans have it, including thousands here in  Raleigh,  Durham, and across the Triangle.

But new studies show the eyes may be a fundamentally important in detecting Alzheimer’s early, before it has a chance to grow.

The problem, according to experts, is that people with Alzheimer’s build up more proteins in the brain than is normally acceptable. The protein is called Beta-Amyloid. It is interesting to note that the retina in the back of the eye is formed from the same material that makes up the brain. And researchers have recently discovered that the amount of beta-amyloid protein is similar in both the brain and the retina.

Now, researchers are testing people’s retinas for these proteins to see if they can identify people who are starting to develop Alzheimer’s.

Researchers are also studying the eyes for other links including:

  • Checking for the beta-amyloid protein in the eye’s lens.
  • Examining changes in eye blood vessel infrastructure in people with Alzheimer’s.
  • Tracking the number of eye flickers, known as saccadic movements, which slow down in people with cognitive problems.

Researchers are trying to catch Alzheimer’s early through testing, but meanwhile, family members can help by looking for these 10 warning signs from the Alzheimer’s Association:

  • Memory changes that disrupt daily life
  • Challenges in planning or solving problems
  • Difficulty completing familiar tasks at home, at work, or at leisure
  • Confusion with time or place
  • Trouble understanding visual images and spatial relationships
  • New problems with words in speaking or writing
  • Misplacing things and losing the ability to retrace steps
  • Decreased or poor judgment
  • Withdrawal from work or social activities
  • Changes in mood and personality

The testing of the human eye for signs of Alzheimer’s, may someday be normal aspect of a routine eye exam. Unfortunately, even with that knowledge, there is not yet a way to slow down or cure the disease.

However, many other eye and other health problems can be caught early through regular eye exams — including many in which early treatment can make a difference, such as glaucoma, cataracts, and age-related macular degeneration.

It’s just one more reason Beth R. Friedland M.D. urges all Park Ophthalmology patients to schedule an annual eye exam as the principal aspect of their overall health.

Diseases are often more than meets the eye.

Not Just Dark Circles: Chronic Sleep Loss Affects Eyes

sira anamwong FDPFor many Raleigh and Durham residents, chronic sleep loss is considered normal and just a part of life we all have to accept. We enjoy our crazy busy lives on the run here in the Triangle. The real warriors plod on, working hard, parenting, enjoying night life and not getting enough sleep. All this despite the fact that sleep loss is linked to heart disease, weight gain, poor performance, diabetes — and eye health problems.

Park Ophthalmology recently addressed sleep apnea and the many health issues it can cause, including floppy eyelid syndrome, glaucoma, and swelling of the optic nerves.

However, even those without sleep apnea who do not get enough hours of shut-eye are risking eye health issues, and not just when it comes to droopy bags and dark circles. Sleep is how our bodies rest, rejuvenate, and prepare for another day. Studies show the human eye needs at least five hours of sleep per night to replenish itself and reach its full working potential.

One common side effect of sleep deprivation is eye spasms. Those annoying twitches are called Eyelid Myokymia. While they do not damage your vision, they can be disruptive. Lack of sleep is the main cause.

Sleep loss over a period of time can also cause other eye health issues, including popped blood vessels in the eye due to strain. Lack of sleep is also associated with dry eye, which causes pain, light sensitivity, itching, redness and blurred vision. Although not always connected to lack of sleep, resting the eyes during the day is also important, and can prevent eye strain, especially for those staring at computer screens all day.

Sleeping is often listed as an eight-hour activity for adults, but studies show individuals in their 20s actually need nine hours. While older adults may require less, the amount is different for everyone. Going to sleep and waking up at a consistent hour each day will help improve sleep and overall eye health.

If lack of sleep seems to be causing problems with your eyes, call Beth R. Friedland M.D. at Park Ophthalmology right away for an appointment.
