The Blood-Brain Barrier

blood brain barrier
This is the 4th article in our series on the brain, memory, and dementia.  This article discusses the blood-brain barrier which protects the brain.

What is the Blood-Brain Barrier?

The blood-brain barrier prevents toxins and microorganisms from crossing from the blood stream into the tissue of the brain. At the same time, beneficial nutrients are capable of crossing this barrier. Generally, integrity of the blood-brain barrier is important and its compromise contributes to a number of neurodegenerative conditions.

Breaking Down Amyloid-Beta Plaque

amyloid plaquesAlzheimer’s disease (AD) is a devastating fatal neurological condition that we’ve all heard or read about or have first-hand experience through our family connection. It is characterized by memory loss and abnormal behavior.

Amyloid beta plaque

This article discusses the role of amyloid beta plaque and the possibility of preventing or slowing its development. Formation of this plaque is the first event in the pathology of Alzheimer’s eventually resulting in nerve cell death.1

Is It Alzheimer’s or Something Else?

Deficiencies and conditions that can mimic Alzheimer’s Disease

nutrient deficiencies and brain effects-250
We continue our series on brain health with this short discussion of nutrient deficiencies and a number of health issues which can cause symptoms similar to Alzheimer’s Disease. These should be checked for anyone showing signs of dementia.  And we should all pay attention to getting a balanced diet with enough of these important nutrients, supplementing if necessary.

The Eye-Brain-Alzheimer’s-Dementia Connection

Natural Brain Support bookThis is the first of a series of articles discussing how to maintain healthy brain function based on my newest book Natural Brain Support: Preventing and Treating Alzheimer’s and Dementia Naturally.

There is a strong connection between eye and brain health, and in fact the optic nerve is brain tissue and the retina was created prenatally from brain cells. Many of the nutrients discussed below are needed for healthy vision but also are found in the brain as well.

An eye doctor can often identify health issues because of observed changes in the retina. An eye doctor can detect hypertension, diabetes, multiple sclerosis, and even Alzheimer’s disease before it gets to the point that the specialists can identify them.

Glutathione is a Super-Antioxidant

glutathione spray supplementGlutatione is rather amazing – low levels are biomarkers for various conditions and it is a “super antioxidant.”

Low levels of glutathione are linked to cataracts, macular degeneration, glaucoma, and brain neurodegenerative problems. The amount of glutathione in blood plasma is considered an overall indicator of the body’s antioxidant defense system.

Glutathione (GSH) is a super free radical fighter with the capacity to neutralize the full spectrum of free radicals. Normal metabolic activity creates free radicals, they can be destructive. They are missing an electron in their outer orbit and therefore try to steal one from a nearby healthy cell, rendering that cell dysfunctional. Continue reading “Glutathione is a Super-Antioxidant”

Effect of Stress on Our Eyes & Health

stressors such as covid fear trigger the fight or flight responseOur bodies are designed to handle stressful situations, referred to as the “flight or fight” mode, wherein when we need to quickly react, the body goes into action and produces hormones that stimulate the adrenal system, raise cortisol levels, and gets our muscles instantly ready to go. Once that situation is resolved, our body has the remarkable ability to return back to homeostasis or normal balance quickly.

But modern-day life may keep one in flight or fight readiness too often. This may be due to ongoing work pressure, relationship and money issues, or the stress related to COVID-19. Chronic stress can, over time, overwork the adrenal system resulting in fatigue and poor circulation.  In turn, fatigue and poor circulation limit the ability of the body to deliver essential nutrients to the eyes.

Floaters in the Eye – Dangerous?

vitreous floaters

Subtle floating shapes

Floaters are a good name for the small dark shapes that float before our eyes. You might not notice them at all unless you are looking for them. They are common as we age. These spots may look like squiggles, strands, or any of a hundred other shapes. Though they can be annoying, floaters are physiologically harmless to the eyes.

But if you suddenly become aware of floaters, particularly accompanied by bright flashes of light, it may signal a vitreous tear or detachment, or a more serious condition such as a retinal tear or detachment, so you should contact your eye doctor right away.

Do You Suffer From Tired Eyes?

man with tired eyes at computerTired eyes are one of the most common complaints eye doctors get from their patients. In this era of computers and mobile devices, the average person in the United States spends about 10 hours, 39 minutes daily in screen time.1


Asthenopia is the technical name for tired eyes. It describes a number of symptoms resulting in eye strain and/or fatigue, red eyes, blurred vision, pain in or around the eyes, mild or severe headaches, and rare double vision which generally begins after many hours of close work on the computer or other close work. Some of these problems arise because computer/smartphone users’ blink rate slows2 causing the eyes to be dry and resulting in eye tiredness. 3 Continue reading “Do You Suffer From Tired Eyes?”
