Why Alzheimer’s Disease is Visible in the Eyes

eyes, the brain and Alzheimer's diseaseThe eyes and the brain are more closely linked than you might realize. Amyloid-beta plaque, the hallmark of Alzheimer’s disease, starts building up in the eyes for a long time before obvious symptoms of dementia appear. Early detection of this brain disease is crucial for slowing its progression. Doctors can screen for Alzheimer’s disease by running a retinal scan. Why? The eyes are neural tissue. Therefore, what is good for the eyes is also good for the brain.

Based on scientific research, Natural Eye Care has recommendations for keeping both your brain and your eyes healthier as you age. We take a holistic approach to Alzheimer’s prevention and management. Early detection, lifestyle, nutrition, and exercise are all important to healthy aging.

Alzheimer’s Disease, Glaucoma and Macular Degeneration: New Research

lifestyle choices such as exercise have an influence on senior healthNew research studies have found strong relationships between lifestyle and the aging brain. How can you help prevent or delay Alzheimer’s Disease and other forms of dementia? The eye’s retina is brain tissue. Not surprisingly, researchers have found connections between Alzheimer’s Disease, glaucoma, and lifestyle. What does the new research show? Are nutrition, supplements, exercise, and smoking avoidance shown to help?

What Are The Chances?

By the age of 65, 10% of seniors have Alzheimer’s Disease. Every five years, the risk doubles. Instead of waiting for any type of dementia to strike, you can take steps right now!

Alzheimer’s Disease is a complex brain disease. Amyloid-beta plaque builds up in the brain. Early symptoms include memory loss, impaired judgment, disorientation, losing items, and personality changes. Later, the brain is fully impaired, resulting in the need for caregivers. Multiple systems in the brain break down, including: Continue reading “Alzheimer’s Disease, Glaucoma and Macular Degeneration: New Research”

All About Omega-3 Fatty Acids

Omega 3 fatty acids foods and supplementsThe standard Western diet, with many processed foods, white grains, fats, sugars, preservatives, and flavorings lacks essential nutrients to support the retina. These non-beneficial components aggravate inflammation in the body – an underlying, and sometimes a direct cause of illness, premature aging, and cellular degeneration.

Essential nutrients include a wide range of amino acids, minerals, vitamins, and vitamin-like nutrients. Among them, a star component of good health and good vision, are the omega-3 fatty acids.

Lutein, Zeaxanthin, Meso-Zeaxanthin – An Update

Your Eyes Benefit from Lutein, Zeaxanthin, and Meso-zeaxanthin

food high in Lutein, Zeaxanthin, Meso-zeaxanthinLutein, zeaxanthin, and meso-zeaxanthin are potent antioxidants found in green leafy vegetables, eggs, corn and even chocolate. They have a profound effect on preserving healthy vision, brain function, the immune and cardiovascular systems.

New research is focusing less on the well-established understanding of local benefit from nutrients, e.g. lutein for macular degeneration or cataract, and more on its systemic benefits affecting the immune system, the brain and cognitive function, the eye, cancer, and cardiovascular health.[1. Buscemi S, Corleo D, Di Pace F, Petroni ML, Satriano A, Marchesini G. The Effect of Lutein on Eye and Extra-Eye Health. Nutrients. 2018 Sep 18;10(9):1321.] In addition, new research is focused on the “why” of the benefit of these carotenoids.

Macular Degeneration

Macular degeneration (AMD) is one of the leading causes of vision loss and blindness. Our retina is abundantly supplied with oxygen but repeated or prolonged exposure to light, especially UV and blue light, decreases long-chain polyunsaturated fatty acids (such as omega-3s) in the retina, increases certain molecular bonds (lipid conjugated dienes), and degrades the photoreceptors and retina.[2. Johra FT, Bepari AK, Bristy AT, Reza HM. (2020). A Mechanistic Review of β-Carotene, Lutein, and Zeaxanthin in Eye Health and Disease. Antioxidants (Basel). Oct 26;9(11):1046.]

Accumulated exposure to UV and blue light can cause accumulation of free radicals, oxidative stress, accelerate vision loss, and hasten breakdown of photoreceptor cells which are essential for vision. Continue reading “Lutein, Zeaxanthin, Meso-Zeaxanthin – An Update”

Mitochondria: Essential Powerhouse for Brain & Vision

Cellular organelles called mitochondria produce energy.

Why are mitochondria essential to your health and well-being?

Mitochondria are the energy batteries of our cells. They are tiny organelles within most cells of the body that provide respiration and energy. Low metabolism develops in the brain as we age and is noticeable in brain regions where mitochondrial structure has changed. [1. Hirai K, Aliev G, Nunomura A, Fujioka H, Russell RL, et al. (2001). Mitochondrial abnormalities in Alzheimer’s disease. J Neuro-sci. May 1; 21(9):3017-23.] The mitochondria attempt to replace themselves whenever they are damaged and destroyed. However, mitochondrial biogenesis can be disrupted. Mitochondrial disease, oxidative stress and free radical damage, drinking alcohol, eating a poor diet, and heavy metals can harm the mitochondria. Research on links between mitochondrial dysfunction and Alzheimer’s Disease are underway. The good news is that lifestyle and natural supplements can support healthy mitochondria functioning.

Natural Eye Care Michael Edson’s Alzheimer’s Article in the Townsend Letter

The latest Townsend Letter features co-owner of naturaleyecare.com Michael Edson, L.Ac., MS  and his article, Underlying Causes and Natural Treatments for Alzheimer’s and Dementia.

The publisher’s discussion of Michael’s article also mentions that studies report that the Tdap (Tetanus, diphtheria, and pertussis) vaccination reduces the risk of dementia by 42% with similar results for flu and pneumonia vaccines.  Both results may be due to reduced overall inflammation in the body.

Top Nutrients for the Brain

Top nutrients for the brain include: ashwagandha, CoQ10, curcumin, DHA, ginseng, gingko biloba, glutathione, lutein, resveratrol, taurine, and vitamins B2, B6, B9, B12, and D3. Interestingly, most of the essential nutrients that support healthy retina, optic nerve and overall eye health are needed in the brain as well and are allowed to pass through the blood-brain barrier.

Melatonin: More than a Sleep Aid

What is Melatonin?

melatonin and sleepingMelatonin is a hormone primarily released by the pineal gland at night, and has long been associated with control of the sleep–wake cycle. It is typically taken at night before bedtime as a supplement. In addition to melatonin’s application as a sleep aid, this supplement can also be used for lowering eye pressure — such as in cases of open angle glaucoma or glaucoma suspects.  Research shows melatonin may also protect the eye’s macula by supporting the functioning of the mitochondria, the tiny “batteries” in each cell. Alzheimer’s disease appears to be linked to poor quality sleep and melatonin production; therefore, melatonin may prove to be a useful supplement and research is underway. Keep reading for details plus information about supplements available on this website.

What Can Melatonin Help?

Insomnia

Melatonin is best known for helping us get to sleep. It is secreted by the pineal gland, acting as the body’s biochemical signal of biological darkness. In other words, our bodies biochemistry signals that you are ready for sleep. Blue light suppresses production of melatonin [1. Gooley JJ, Chamberlain K, Smith KA, Khalsa SB, Rajaratnam SM, et al. (2011). Exposure to Room Light before Bedtime Suppresses Melatonin Onset and Shortens Melatonin Duration in Humans. J Clin Endocrinol Metab. Mar;96(3):E463-72.] to a surprisingly profound degree.[2. Vartanian GV, Li BY, Chervenak AP, Walch OJ, Pack W, et al. (2015). Melatonin Suppression by Light in Humans Is More Sensitive Than Previously Reported. J Biol Rhythms. Aug;30(4):351-4.]

If you are exposed to blue light right before bedtime (e.g. checking your email one more time), it throws off the internal rhythm that allows you to get adequate sleep. Nearly 75% of children now use some sort of electronic device in their bedroom. The use of these devices markedly impacts sleep quality, which in turn, contributes to social adjustment problems, behavioral problems in school and at home, and surprisingly, weight gain.

Similarly, it has been found that sleeping in a room that is not dark, also disrupts sleep, or makes it less effective in reducing fatigue and alleviating the accumulated stress of the day. Most studies found that exposure to light in the room, during sleep, reduces melatonin production by 50%.

While most research on the effects of smartphones on sleep and circadian rhythms have involved children and teens, adults are also adversely impacted. One Flemish study included more than 800 adults, 50% of whom owned smartphones, and 60% of whom used their smartphone during the night. Nighttime phone use and texting at night markedly increased how long it took to fall asleep and markedly decreased the quality, duration, and efficiency of sleep. In younger adults, nighttime electronic-device use was tied to more fatigue and later rising time. In older adults, it was associated with shorter sleep duration and earlier rise time.[3. Exelmans L, Van den Bulck J. (2016). Bedtime mobile phone use and sleep in adults. Soc Sci Med. Jan;148:93-101.]

Recommended dosage is 1mg–3mg before bedtime.

Supports the Immune System

Melatonin plays a dual role in supporting the immune system, at least partially because it helps promote glutathione levels in the body, an essential master antioxidant.  It communicates with the immune system and influences white blood cells to fight infections and inflammation. Lowered levels of the super antioxidant glutathione[4. Glutathione is actually the antioxidant found in greatest quantity in the brain and found to be deficient in the brains of Alzheimer’s and Parkinson’s patients.] are present in “clinical conditions like autoimmune disorders, neurological disorders, diabetes, and microbial infections”[5. NaveenKumar SK, Hemshekhar M, Jagadish S, Manikanta K, Vishalakshi GJ, et al. (2020). Melatonin restores neutrophil functions and prevents apoptosis amid dysfunctional glutathione redox system. J Pineal Res. Oct;69(3):e12676.] which are characterized by white blood cells. In other words, melatonin protects white blood cells from free radicals by supporting normal glutathione levels.

Lowers Eye Pressure

Intraocular pressure (IOP) is usually lowest at night, which is also when natural levels of melatonin are near their high in the circadian cycle. IOP is highest in the morning when melatonin is low. There seems to be a correlation between IOP and melatonin; supplementing with melatonin may lower IOP. [6. Samples, J.R., Krause, G., Lewy, A.J. (1988). Effect of melatonin on intraocular pressure. Curr Eye Res. Jul;7(7):649-53.] [7. Alkozi HA, Navarro G, Franco R, Pintor J. (2020). Melatonin and the control of intraocular pressure. Prog Rentin Eye Res. Mar;75:100798.]

Protects the Macula

Melatonin also protects the macula, the center part of the retina which is responsible for your central vision needed for close-up work such as reading. Age-related macular degeneration (AMD) is the loss of central vision and is caused by deterioration of the macula. A combination of melatonin (3mg), zinc (8.7mg), and selenium (50 mcg), taken before bedtime, helps stabilize AMD with some remarkable improvement in the fundus of the eye after taking the combination for 6 months. [8. Stefanova NA, ZHdankina AA, Fursova AZ, Kolosova NG. (2013). Potential of melatonin for prevention of age-related macular degeneration: experimental study (in Russian). Adv Gerontol. 2013;26(1):122-9.] [9. Yi C, Pan X, Yan H, Guo M, Pierpaoli W. (2005). Effects of melatonin in age-related macular degeneration. Ann N Y Acad Sci. Dec;1057:384-92.]

Supports Mitochondrial Functioning

A 2020 review proposed that melatonin protects the macula by supporting mitochondrial function. Mitochondria are the “energy-producers” of cells, and are essential for cellular health. As we age DNA repair functions, antioxidant activity, and lack of mitochondrial renewal lead to significant increase in free radicals. These changes cause inflammation and premature cell death in the retinal pigmented cells that protect the retina and macula.[10. Mehrzadi S, Kemati K, Reiter RJ, Hosseinzadeh A. (2020). Mitochondrial dysfunction in age-related macular degeneration: melatonin as a potential treatment. Expert Opin Ther Targets. Apr;24(4):359-378.]

Helps Night Vision

Photosensitive retinal ganglion cells (melanopsin-expressing retinal ganglion cells “mRGC”) release melanopsin which affects pupil dilation and adaption and suppresses melatonin[10. Bonmati-Carrion MA, Arguelles-Prieto R, Martinez-Madrid MJ, Reiter R, Hardeland R, et al. (2014). Protecting the melatonin rhythm through circadian healthy light exposure. In J Mol Sci. Dec 17;15(12):23448-500.] between dark and bright light (such as recovery after glare of an oncoming car headlights).

Melanopsin’s presence in retinal nerve cells is linked to reduced levels of melatonin and the relationship may be involved in poor night vision. At night, melatonin is secreted by rod and cone photoreceptors, functioning as a dark adaptive signal and it, in turn, modulates these photoreceptors.[11. Pack, W., Hill, D.D., Wong, K.Y., (2015). Melatonin modulates M4-type ganglion-cell photoreceptors. Neuroscience, Sep 10;303:178-88.]

Aids Alzheimer’s Disease Issues

Melatonin may be a useful agent in preventing and treating Alzheimer’s disease (AD).  Classic markers of AD include the build-up of beta amyloid plaque, as well as excessive tau protein resulting in neurofibrillary fiber build-up.[12. This is discussed in detail, along with other underlying factors and causes including natural treatment strategies, in my book Natural Brain Support: Your Guide to Preventing and Treating Alzheimer’s, Dementia and Other Related Diseases Naturally.]

The production of melatonin runs parallel to AD progression. Quality of sleep is dependent upon melatonin, and it appears to be a safe and effective treatment for AD patients with sleep dysfunction.[13. Wang YY, Zheng W, Ng CH, Ungvari GS, Wei W, et al. (2017). Meta-analysis of randomized, double-blind, placebo-controlled trials of melatonin in Alzheimer’s disease. Int J Geriatr Psychiatry. Jan;32(1):50-57.] Melatonin stimulates non amyloidogenic processing and inhibits beta amyloid precursor protein processing which culminates in amyloid aggregates – a neuroprotective function in AD pathology.[14. Shukla M, Govitrapong P, Boontem P, Reiter RJ, Satayavivad J. (2017). Mechanisms of Melatonin in Alleviating Alzheimer’s Disease. Curr Neuropharmacol. 2017;15(7):1010-1031.] It decreases AD-like tau hyperphosphorylation, protects the cholinergic system and is anti-inflammatory. It may be a useful agent in preventing and treating AD.[15. Lin L, Huang QX, Yang SS, Chu J, Wang JZ, et al. (2013). Melatonin in Alzheimer’s disease. Int J Mol Sci. Jul 12;14(7):14575-93.] Weak melatonin signaling (melatonin receptor type 1A gene) appears to contribute to the cascade of AD pathology.[16. Sulkaya S, Muggalla P, Sulkava R, Ollila HM, Peuralinna T, et al. (2018). Melatonin receptor type 1A gene linked to Alzheimer’s disease in old age. Sleep. Jul;41(7):zsy103.]
