Newsletter #136 --- Memory and Cognition Enhancing Approach

 

Causes of severe memory loss

  1. Deposits of amyloid-beta plaques and neurofibrillary tangles from abnormally hyperphosphorylated tau protein with loss of microtubule transport in neurons leading to communication problems between neurons. Later on, a massive loss of neurons occurs.
  2. Multiple episodes of decreased blood flow through the arteries in the brain leading to multiple areas of localized brain damage.
  3. Mitochondrial dysfunction as we get older. One of the critical components of aging is that mitochondria produces high levels of free radicals which can in turn damage the mitochondria. Mitochondria are small compartments within all of our cells that function as power plants by breaking down food and generating about 95% of our cellular energy.

 

Healthy Life Style promotes healthy memory as we age

Memory and Cognition Enhancing Nutrients

Risk of memory and cognition loss can be reduced and memory health can be improved by supplementing with the following neurologically beneficial nutrients targeting the above causes.

 

Huperzine A or HupA

Huperzine A is a natural herb for Memory, Concentration and Alzheimer's - Huperzine A is a natural Chinese herbal remedy extracted from club moss (Huperzia serrata) may significantly improve memory and mental function -- with none of the negative side effects of commonly prescribed prescription drugs. HupA has been used in Chinese medicine for centuries to treat inflammation. HupA works in a similar fashion to the two most commonly prescribed drugs for Alzheimer's disease, tacrine (Cognex) and donepezil (Aricept). All three inhibit the breakdown of acetylcholine. While all three have been shown to enhance memory, boost acetylcholine and protect brain cells from toxins, HupA has none of the significant side effects of the prescription drugs, which can cause nausea, vomiting, excess sweating and salivation, and liver damage. HupA also has a longer duration than both of these drugs. Several studies have shown that HupA improves brain function in patients with dementia. HupA seems to have additional properties that may help it to slow the progression of Alzheimer's. One study showed that it can slow the formation of a harmful plaque, a buildup of protein deposits in the brain. Other studies indicate that it can protect brain cells from glutamate, a neurotransmitter that becomes toxic when it is secreted in large amounts. Some research also indicates that Huperzine A helps to block the process of inflammation that occurs as Alzheimer's disease progresses. The recommended dose of Huperzine A is 100-200 mcg per day in divided doses. It may take 2-3 months to see clinical improvement. A double-blind placebo-controlled study evaluated 103 people with Alzheimer's disease who received either huperzine A or placebo twice daily for 8 weeks. About 60% of the treated participants showed improvements in memory, thinking, and behavioral functions compared to 36% of the placebo-treated group, and the difference was significant. Benefits were also seen in an earlier double-blind trial using injected huperzine in 160 individuals with dementia or other memory disorders. Huperzine is also reportedly helpful for improving memory in healthy individuals. A double-blind trial of 34 matching pairs of junior middle school students reported improvements in memory in the treated group.

 

Acetyl-L-Carnitine

Acetyl-L-carnitine protects neurons by neutralizing free radicals, stabilizing cellular membranes, and enhancing the activity of acetylcholine. Acetyl-L-carnitine increases the transport of fatty acids into mitochondria. This amino acid enhances brain energy, helping both to improve mood and to reduce the effects of age-associated memory impairment. It also improves cellular energy production for mental and physical stamina. Placebo controlled studies have shown that acetyl-L-carnitine (ALC) can also help improve nerve health. Consider 1,000 mg of acetyl-L-carnitine as a good maintenance dose for long term administration when combined with other beneficial nutrients such as CoQ10 and alpha lipoic acid.

 

Phosphatidyl-serine

Phosphatidyl-serine is a cell membrane phospholipid that improves membrane flexibility and permeability which helps connections between neurons and improves the release of two important neurotransmitters, acetylcholine and dopamine. Phosphatidylserine supports and revitalizes nerve cells and has been shown in many studies to slow or reverse cognitive losses attributed to aging. Phosphatidyl-serine has been proven to improve attention, concentration, mood, and short-term memory; it also enables nutrients to enter brain cells more easily and supports the function of neurotransmitters. Three randomized double blind, placebo controlled trials reported that people with poor cognitive health given phosphatidylserine significantly improved attention, memory, verbal skills and daily activities.

 

Ginkgo biloba

Ginkgo Biloba extract has several major effects: antioxidant protection from free radicals within cells including protecting mitochondria, dilating blood vessels by releasing endothelium-derived relaxing factor, inhibiting platelet-aggregating factor and thereby blocking blood clots, inhibition of stress response of excessive glucocorticoid steroid and promoting the release of alpha amyloid precursor protein which is neuroprotective and enhances memory. The large majority of double blind, placebo controlled clinical trials have found supplementation with ginkgo biloba extract to be effective for helping people with poor memory function. Most of these clinical studies used 240 mg per day. Ginkgo Biloba Boosts Brain Power and Support Alzheimer's Disease. Ginkgo Biloba is an antioxidant, meaning it scavenges the blood for harmful free radicals (toxins) that would otherwise interfere with normal brain chemistry and function. Ginkgo also improves blood flow, hence increased oxygen availability to brain cells. Mounting research demonstrates that it can increase mental alertness and improve memory, not only in Alzheimer's patients, but in otherwise mentally fit individuals who don't want to lose any of their brain power to aging.

 

Introducing Cogni-Flex

Cogni-flex is an advanced formula providing nutritional support for healthy mental function. The four nutrients in Cogni-flex support the structure and function of cognitive processes in several ways. They support neurotransmitter metabolism, enhance vascular circulation to the brain, and help maintain structure and function of nerve cell membranes. These four nutrients are Huperzine A, Phosphatidyl Serine, Acetyl L-carnitine and Ginkgo biloba.

I recommend one Cogni-Flex twice a day with Acetyl-L-Carnitine 1000- 2000mg/day for Enhancing Memory and Cognition.

 

Alpha lipoic acid

Alpha Lipoic Acid is a powerful antioxidant which is active in water-soluble as well as lipid-soluble areas of the body including the brain. Furthermore, alpha lipoic acid can regenerate oxidized, inactive vitamin E, vitamin C and CoQ10 back to being active antioxidants. Alpha lipoic acid is an essential cofactor for several mitochondrial enzyme complexes that catalyze critical reactions related to energy production and the catabolism (breakdown) of fatty acids and amino acids. Double-blind placebo controlled trials have shown that alpha lipoic acid 600 mg per day can help improve nerve health. The most common cause of poor nerve health is elevated blood sugar levels so common in today's society because of the over consumption of sugar and other simple carbs.


Coenzyme Q10 (CoQ10)

CoQ10 is part of the electron transport chain in mitochondria and is critical for mitochondrial energy production. Acetyl-L-carnitine, alpha lipoic acid and/or CoQ10 increase mitochondrial energy production which also increases dangerous free radical formation. CoQ10 and alpha lipoic acid are powerful antioxidants which protect the cells and particularly the mitochondria from free radical damage. The combination of CoQ10, Alpha Lipoic Acid and Acetyl-L-Carnitine may be synergistic for increasing mitochondrial energy production while protecting mitochondria from free radical damage and may increase mental stamina and physical stamina. For example, studies in elderly rats have shown a synergistic improvement using alpha lipoic acid together with acetyl-L-carnitine for improving memory tasks by lowering oxidative damage and improving cellular energy production in mitochondria.


L-carnitine

L-Carnitine It is never too late to start nutritional supplementation. A placebo-controlled study of extremely old people (over one hundred years old) given L-carnitine reported increase of total muscle mass, reduction in total fat mass, improvement in mental fatigue as well as physical fatigue and improvement in cognitive health. Carnitine has also been reported to improve attention in people with problems concentrating. Aged dogs with cognitive decline given a supplement which included phosphatidylserine, alpha lipoic acid, L-carnitine and CoQ10 for two months had significant improvement in disorientation, social interaction and soiling.

 

Green tea

Three studies reported that drinking five cups or more of green tea daily was associated with more than a 50% reduction, a 65% reduction and a 69% reduction in the risk of brain damage from decreased cerebral blood flow. You can also take Green tea extract containing the most potent antioxidant bioflavonoid which is capable of reducing inflammation and pain, strengthen blood vessels, improve circulation, fight bacteria and viruses, improve liver function, lower cholesterol levels, improve vision and even helps burn calorie and loose weight.


Magnesium

Approximately 80% of people are considered to have a magnesium deficiency. An epidemiological study of 26,556 Finnish male smokers reported that men with the highest magnesium intake, average 589 mg per day, (as compared to the lowest consumption averaging 373 mg per day) were associated with a 15% lower risk of blockage of blood flow to the brain with permanent brain damage.

 

Pomegranate

A placebo-controlled study of people with narrowing of their carotid arteries (which are major arteries in the neck for blood flow to the brain) reported that drinking one glass a day of pomegranate juice resulted in improvement of the carotid arteries. Pomegranates have high levels of a unique family of antioxidants called punicosides. Cardio-Edge contains Pomegranate Extract and other cholesterol lowering nutrients such as Plant Sterols, Sytrinol and tocotrienols - a formula that embodies the most recent science to help maintain cardiovascular health and support healthy cholesterol levels.


Omega 3 Fatty Acid

Low fish intake and low blood levels of the omega-3 DHA are associated with increased risk of poor memory health in humans and in mice. Furthermore, when these mice were given omega-3 DHA starting later in life, there was marked reduction in amyloid beta accumulation in the brain, reduction in oxidative brain damage, and improved cognitive function.Epidemiological studies report that regularly eating cold-water fatty fish as well as a placebo-controlled study giving omega-3 fish oil EPA and DHA in softgels are associated with better cardiovascular health. Healthy brains generally contain high levels of DHA whereas low levels of DHA have been found in brains of people with amyloid beta accumulation and severe memory loss.

The Framingham Heart Study measured the omega-3 DHA blood levels and then prospectively followed for 9 years 899 people (average age of 76 years). Cognitive function was tested every 2 years. People with the highest quartile (top 25%) of DHA blood levels had an average DHA intake of 180 mg per day, average fish intake of 3 servings per week and had a 47% reduction of the development of poor memory health (as compared to the other 75% of people with lower DHA blood levels). People who averaged two servings of fish per week did not have a reduction of the development of severe memory loss.

The optimal dosage of omega-3 EPA and DHA appears to be 2,000 mg per day. Unfortunately the amount of mercury and other heavy metals plus PCBs in most fish would make it dangerous to attempt this level by just eating fish. I recommend the fish oil supplement which is molecularly distilled to remove mercury and other heavy metals and PCBs, pharmaceutical quality. I recommend taking
Omega 3 2 - 4 softgels per day.
