Magnesium L-Threonate: New Weapon for Brain Protection

It has been lately discovered that magnesium is vital in the activation of nerve channels that are involved in synaptic plasticity, meaning that magnesium is a critical player for the physiological events that are fundamental to the processes of learning and memory.
One form of magnesium in particular, magnesium L-threonate, has the unique ability to permeate the brain and enhance the receptors that are involved in this process. Many forms of magnesium do not effectively cross the blood brain barrier. The magnesium threonate is a chelated magnesium (similar to magnesium Glycinate) which binds the magnesium with a carrier molecule, in this case the amino acid, L-threonate. This chelation provides a form or magnesium that effectively crosses the blood brain barrier and positively impacts synapses. 
As reported in the Journal, Neuron, researchers demonstrated in laboratory animals actual enhancement in the learning abilities, working memory, as well as short and long-term memory, and even quality of sleep when given magnesium magnesium threonate.
One of the most aggressively studied forms of magnesium L-threonate is a patented version by the trade name, Magteinä, developed by researchers at MIT, including a Nobel Prize winner. Their research has  demonstrated actual restoration of function in aging neurons in laboratory animals. Further, it appears that Magteinä may, in fact, be the only form of magnesium that significantly increases the levels of magnesium within the brain.
Anecdotal reports in humans are showing benefits for PTSD, anxiety, and depression as well.  
Magnesium is involved in over 300 biochemical processes in the body, including binding to neurotransmitter receptors and as a co-factor for neuronal enzymes.  The Magnesium L-Threonate appears to be a form preferable for cognitive decline and neuron protection.

Turmeric: Surprising Benefits for Brain Health

The common spice, turmeric, has been used in various types of treatments for dementia and traumatic brain injury.  Research is also showing surprisingly powerful effects of turmeric on Alzheimer's disease (AD)1.

A growing body of evidence indicates that oxidative stress, free radicals, beta-amyloid plaque, metal toxicity, and abnormal inflammatory reactions contribute to AD pathology.  Due to the various effects of turmeric, including antioxidant, anti-inflammatory, and lipophilic (an affinity for fats) properties, decreased amyloid plaque, metal-chelation, and decreased microglia formation, the overall memory in AD patients using turmeric in studies has improved.

In one 2013 study in particular2, older rats experienced a "remarkable restoration" of brain function when given turmeric, especially the ability of vessels in the brain to relax and allow blood to flow freely.  The treated rats also experienced a reduction in reactive oxygen species (ROS), which is associated with decreased oxidative stress and cell damage.

The effects of turmeric on AD were also demonstrated in a 2012 case study3 on three patients with "very severe" manifestations of the disease: irritability, agitation, anxiety, apathy, incontinence, and wonderings.  The patients were given 764 of turmeric every day for 12 weeks.  The results were that "behavioral symptoms improved remarkably as a result of the turmeric treatment."  In two of the tree patients, "they came to recognize their family within 1 year treatment."  

Turmeric is a common spice that can be added to food.  However, therapeutic levels such as the ones used in the studies are easier to obtain via turmeric-containing food supplements.  Additional good news is that even higher levels in supplement form are not usually expensive.

Neurofeedback: A Powerful Tool for Cognitive and Developmental Testing and Rehabilitation

Once in a while I run across a device or therapy other than that of nutritional protocols that I feel is important to share. Neurofeedback is one such therapy that holds promise for those with cognitive issues and for parents with children who have developmental challenges.


Sometimes referred to as EEG (Electroencephalogram) or Neurotherapy, Neurofeedback is the process of training a brain to learn to modify or control the brainwave activity through auditory and visual feedback. Neurofeedback is a gentle method of creating a balance within the central nervous system. It is painless and non-invasive in its approach.


The training process is measured by use of pictures on a computer screen and sensors on the head. The approach can be compared to potty-training. An individual is taking an internal organ and training it to respond by feedback. If a patient is producing an amplitude (strength of a signal) in a specific frequency level that is within the parameters that the technician has set, then music will begin and the picture will move. If the individual is outside those parameters then the music and the movement stops.


The process starts with a compilation of the participants emotional, behavioral and cognitive abilities, concerns and personal goals. After a thorough meeting involving some standardized tests and reviewing their social history a profile is created. The profile is used to develop academic and cognitive strategies for school, home and work. This profile is a starting point for memory, problem solving, reasoning and speed processing enhancement.


Most individuals will be asked to come as often as possible in the beginning of their therapy. It is not uncommon to come 5 days a week in the beginning. The first twenty sessions are the most important. The central nervous system is learning a new neuronal pattern and just like exercising any muscle the more it is practiced the more habitual that movement becomes. The total number of sessions vary and are dependant on the individual, their progress and their personal goals. A common number of therapy sessions range from 25-40.


Computer games, board games and card games are many times used during the session as a method of teaching a new cognitive strategy. Relaxation techniques such as autogenics, visualization, Hemi-Sync music and diaphragmatic breathing are taught to the individual as well.

Many times "home work" is given to the family so they can continue to practice at home, school or at the workplace.


EEG neurofeedback helps many different disorders and conditions. It seems to be effective for several reasons: It helps to remind the body how to relax the muscles, which allow the nerves to "let-go" and not respond until needed. It also allows the blood to flow through the body at a normal rate and volume keeping blood pressure lower during daily activity. Most disorders or conditions are affected by stress. Therefore, as the body reacts to the stress in a different manner the characteristics of these diagnosis' will decrease.


Conditions that can be treated by neurofeedback are:

· Anxiety Attacks
· Apraxia
· Aphasia
· ADHD
· Autism
· Bi-polar Disorder
· Depression
· Dyslexia
· Hypertension
· Learning Disabilities (LD)
· Migraines
· Oppositional Defiance Disorder (ODD)
· Pain Management
· Stroke
· Tourette Syndrome (TS)
· Traumatic Brain Injury (TBI)


Benefits to Expect:


Improved Sleep:

· Falls asleep within 20 minutes
· Stays asleep
· Wakes Refreshed

Cognition:

· Improved memory skills
· Increased flexibility in thinking
· Heightened sense of documentation and focus
· Increase in the speed of processing information
· Better reasoning skills
· Able to think faster
· Better strategizing and deduction skill

Behavior:

· Better sense of self control
· Better social skills
· Less anxiety
· Less needless body movement
· Less impulse behavior
· Less obsessive/compulsive behavior
· Reduction of addictive behavior

Attitude:

· More involved with family events and discussions
· More willing to share ideas and thoughts
· Happier and more content
· More composed physically/mentally
· Better self confidence
· Reduction of stress related behaviors such as headaches, nail biting, twisting hair, hair pulling, motor or vocal tics


I was introduced to neurofeedback through my friend and client, Dr. Lise DeLong, PhD, who is the founder and director of Cognitive Connections on the southside of Indianapolis. Dr. DeLong also offers a variety of nutritional protocols related to cognitive function and stress, as well as hyperbaric oxygen therapy, which helps to oxygenate the brain and body and can be useful for a variety of conditions. Her website offers some compelling case studies on Neurofeedback. http://www.cognitive-connections.com/.

Wonder Nutrients for Cognition, Part 3

In the two previous posts I focused on specific natural compounds, Huperzine A and Ginko, that are effective in managing cognitive decline. In this post I’ll provide strategies for effective overall brain protection, focusing on a single product which has become one of my personal favorites because of its rich content of three nutrients primarily: Acetyl-L-Carnitine (ALC), N-Acetylcysteine (NAC), and Grape Seed Extract.

Acetyl-L-Carnitine (ALC)
ALC is a vitamin-like substance that is responsible for the transport of fatty acids into and out of the mitochondria, and is the form of carnitine found naturally in brain tissue and is thought to be substantially more active in the CNS. ALC increases cardiolipin, which is an important phospholipid that serves as a co-factor for a number of critical mitochondrial transport proteins. Supplementation with ALC may also improve energy production within brain cells.


An analysis of controlled studies reports that persons with subclinical or clinical dementia given 1.5 to 3 g ALC daily have shown improvement in numerous clinical measures of cognitive function. In two large multicenter, crossover trials, geriatric patients given 1500 mg of ALC daily for 90 days experienced improvements in clinical tests of cognition, memory, and depression over controls. In other double-blind, placebo controlled trials, ALC-treated subjects showed less mental deterioration as rated by cognitive and AD assessment test scores.


N-Acetylcysteine (NAC)
The protective effect of NAC is believed to be related to its restoration of brain glutathione (GSH) levels. GSH is central to antioxidant defenses in the brain and is an important component of detoxification of ROS. GSH, however, does not cross the Blood-Brain-Barrier, so oral supplementation with precursors such as NAC and alpha-lipoic acid are the best way to increase brain levels.


NAC has been shown to increase mitchondrial complex 1 activity and markedly improve mitochondrial electron transport chain activity. In animal models of traumatic brain injury, NAC significantly restored mitochondrial energy producing mechanisms (electron transfer, energy coupling capacity, calcium uptake activity.


Other Vital Nutrients for Brain Function included in Ceralin Forte:


  • Grape Seed Extract: Acts as a neurological antioxidant, provides protection for nerve cells, and supports circulatory function.

  • 5-Methyltetrahydrofolate (5-MTHF): Supports neuron life cycle, neurotransmitter metabolism, methylation, homocysteine metabolism, and nervous system function.

  • Vitamin B6: Involved in the conversion of glutamate into calming GABA,supports neuron life cycle and nervous system function, as well as methylation and homocysteine metabolism.

  • Vitamin B12: Supports neurotransmitter metabolism, neuron life cycle, methylation, homocysteine metabolism, and nervous system function.

  • Thiamin and Riboflavin: Involved in mitochondrial function.

  • Niacinamide: Provides neuron protection and nervous system function.

Putting Together a Brain Protection Protocol
Unfortunately some of the best formulas for neuron protection are also the most expensive. However, a good one-two combination that is cost effective is the Ginko and Rosemary formula along with EPA/DHA from fish oil. You’ll recall from previous posts that EPA and DHA from fish oil provide support for the brain and nervous system such that it has actually been shown to raise the IQ. For those over 40 who are not feeling quite as mentally sharp, I like the addition of the brain antioxidant formula featuring acetyl-L-carnitine, NAC, and grape seed extract at 1 capsule 2-3 times per day. This formula provides some great cross-over antioxidant support that is also important for detoxification and many other body functions. For those experiencing noticeable cognitive decline, the use of the Huperzine A formula is a must at atleast 2 per day.

Wonder Nutrients for Cognition, Part 2

Spencer Johansen is the Police Chief in Lexington, Ill. He was only 49 years of age when he was diagnosed with Alzheimer’s Disease.

Unfortunately the early onset of Alzheimer’s Disease in Spencer Johansen’s case is not isolated. Cases of younger and younger people, some in their early forties, are being reported.
The reasons behind this frightening trend are many and varied. Chronic stress, poor body composition, environmental toxicity, cell phones use, and nutrient deficiency are just some of the many reasons why people get Alzheimer’s Disease and dementia. Thus, lifestyle modification is a key component in not only preventing but also treating cognitive decline with age.
Eating a whole foods diet comprised of fresh fruits and vegetables (preferably organic), lean meats, whole grains, and lots of purified water (not tap water), while cutting back on or eliminating fast foods and packaged foods is the starting place. That needs to be followed up by getting more active, as research is now showing that exercise is as good for the brain as it is the rest of the body.
Removing one’s self from stressful situations, if possible, is also another important component of prevention and treatment. Stress raises cortisol and inflammatory mediators which, if chronic, can cause a catabolic state throughout the body which can break down muscle tissue and effect the brain and nervous system. It is now thought that even negative emotions such as anger, resentment, and unforgiveness can likewise effect all the organ systems by causing these same “molecules of emotion” – as they have been called – to continue coursing through the body.

Brain Protection in Nature
Nature’s pharmacy provides some of the most remarkable substances on the planet in preventing and treating diseases of the brain.

The herb, Ginko Biloba, while no longer considered cutting-edge like newer and novel agents such as huperzine A (see my last post of huperzine), is still an important consideration in brain health because of its broad-spectrum effect on brain tissue and its relatively low cost.

Ginko is an approved treatment for dementia in Germany, and is the only non-prescription substance considered a treatment for dementia in Canada. Many European studies have demonstrated the effectiveness of Ginko in the treatment of patients with age-associated memory and cognitive impairments as well as dementia and Alzheimer’s Disease.


The first clinical trial in the U.S. showed that patients with dementia and Alzheimer's receiving 120 mg per day improved the cognitive performance and social functioning of a substantial number of cases compared to a worsening of the conditions in the control group.1


Other benefits of Ginko include:
  • Scavenges oxidative radicals
  • Inhibits platelet aggregation
  • Improves circulation to the brain
  • May help normalize cerebral metabolism under hypoxic conditions
  • May prevent changes in mitochondrial morphology and function associated with aging of the brain.
  • Shown in animal studies to possess anti-stress and adaptogenic properties by decreasing blood glucocorticoid levels and increasing adrenocorticotrophic hormone levels, showing positive potential for stress-related cognitive impairment; prevents stress-induced learning impairment and elevations in stress hormones; and increases acetylcholine synthesis and turnover of norepineprhine. 2,3,4

Some recent studies have called into question the effectiveness of Ginko, but it is important to note that the leaf of Ginko is the most therapeutic part of the plant, rather than the stem or the root. However, a company can use the various parts of the plant in a Ginko product and still call it Ginko. Yet the therapeutic effect of the product would be substantially lower than a product utilizing strictly the standardized extract of the leaf.

It is also now widely held that many negative reports on natural substances are from studies funded in part by drug companies who cannot patent or sell substances like Ginko and who therefore wish only to cast these therapeutic substances in a negative light so as to protect the profit on the sale of their drugs. Upon investigating the poor study design of many of these studies, it would appear that that belief certainly has the ring of truth to it.

In the case of Ginko, the well-designed studies clearly show marked improvement in many aspects of cognition and brain health.

A cutting-edge approach for Ginko supplementation is to combine 60 mg of standardized Ginko leaf extract along with the added therapeutic and antioxidant benefits of Rosemary. Two tablets provide the therapeutic dose of 120 mg used in the studies.

Wonder Nutrients for Cognition, Part 1

Cognitive decline is an increasing concern in industrialized nations. While advances in hygiene, science, and medicine has led to the longest life expectancy in modern history, diseases that affect the nervous system are now being diagnosed in record numbers in the U.S. For example:

— 6.8 million Americans suffer from dementia (1 in 10)
— 4 million have Alzheimer’s Disease, a number expected to quadruple in the next 40 years.
— 1.5 million suffer from Parkinson’s Disease with 50,000 new diagnoses each year.1,2

It is generally agreed that genetics play an important role in whether or not a person develops a neurological disease. However, the loss of physiological function in humans is not relegated to genetics alone. Research indicates that nutrition and other environmental factors can modify the phenotype – the ways our genes are expressed.3 If a person has a genetic predilection for Alzheimer’s Disease, for example, that person’s diet, toxin exposure, and level of stress can turn that biochemical switch on or off. Thus, a person may or may not express the disease depending on their lifestyle.

Natural Support for Cognitive Function
One of the more exciting discoveries in the field of natural medicine pertaining to cognitive function was by the Chinese. In the 1980s the Chinese government began to explore new applications for many of their traditional herbs, and they discovered a compound in Chinese Club Moss – traditionally used for trauma – called, Huperzine A, which has shown promising benefit for cognitive function by acting as an acetylcholinesterase (AChE) inhibitor.

Acetylcholine is a chemical formed from the precursors choline and acetylcoA and catalyzed by choline acetyltransferase (CHAT). Acetylcholine facilitates communication between neurons and mediates release of other neurotransmitters. Its function is critical for cognitive processing, memory, arousal, and attention. It can be destroyed, however, by the presence of the AChE enzyme, which breaks down acetylcholine back into choline and acetylcoA. Therefore, current drugs for the treatment of Alzheimer’s exert their effects by blocking AChE and increasing synaptic acetylcholine levels. Unfortunately, these drugs are not without unfavorable side effects.

The compound, Huperzine A, however, has shown inhibitory effects against AChE without the negative side effects associated with AChE-inhibiting drugs. It is so effective that there are pharmaceutical companies attempting to make drugs from Huperzine A, it has been favorably reported on by JAMA, and it is now licensed for distribution through the Mayo Clinic. Huperzine not only protects acetylcholine from the damaging effects of AChE, but it also provides multiple neuroprotective effects via its brain-specific antioxidant properties, and it also readily crosses the Blood-Brain Barrier.

Other benefits of Huperzine A include:
  • Anti-excitotoxic and anti-apoptotic effects
  • Greater activity at N-methyl-D-asparate (NMDA) receptors
    -NMDA antagonist
    -Inhibits glutamate neurotoxity, an effect not seen with donepezil or tacrine (Ved, 1997)
    -Direct, specific activity at NMDA receptor (Wang, 1999; Gordon, 2001; Zhang, 2001
  • Antioxidant effect
  • Huperzine A protects against hydrogen peroxide induced apoptosis in PC12 cells (Xiao, et al, 1999)
  • Reduces hippocampal oxidative damage in aging rats (Shang, et al., 1999)
    -Protection against amyloid toxicity in vitro and in vivo
  • Blocks suppressive effect of AB on long-term potentiation in rat hippocampal slices (Ye, 1999)
  • Attenuates AB toxicity in cell lines (Zhang, 2002) and primary neuron cultures (Xiao, 2002)

One needs to be aware that currently 100% of the research available on Huperzine A is done with the purified form, not the standardized extract. The purified form is the more expensive version, but currently it is considered the better of the two forms.

Palm Tocotrienols
There are a number of natural vitamin-E tocotrienols, most of which are derived from palm. Based on the NIH-funded study at the Ohio State Medical Center on neuron protection, it was found that the palm tocotrienols are extremely effective in protecting brain cells from toxicity, with alpha-tocotrienols showing the best benefit. Palm tocotrienols are the only source of significant levels of alpha-tocotrienols, and are the most widely researched source for antioxidant cardiovascular protection.

5-Methyltetrahydrofolate (5-MTHF)
5-Methyltetrahydrofolate (5-MTHF) is the end metabolite of folate metabolism. It is able to enter the cerebrospinal fluid where folic acid does not. It likewise crosses the Blood-Brain Barrier where folic acid does not. It is also effective in reducing homocysteine, an important factor in maintaining proper neurological and cardiovascular health. Folate is a major contributor to methylation, as well as playing an important role in overall neurological function.

Putting it Together in One Formula to Support Acetylcholine/Brain Function
There is only one company that I know of offering a cognitive support product rich in the purified Huperzine A, along with palm tocotrienols and 5-MTHF. Individuals benefitting most from this unique formula would be those who are:

  • Over 40 years of age and want proven protection
  • Feels their memory is not as sharp as it used to be
  • Forgets names of people
  • May have a family history of dementia
  • Has a personal history of head trauma
  • Can’t learn new things as fast as they used to (e.g., hooking up a DVD player, remote control)
  • Is in the early to mid stages of dementia or Alzheimer’s.

While the prevalence of neurological disease is on the rise, thankfully so are natural and proven approaches for neuro protection.
