GABA Metabolism in the CNS in Addiction

What is GABA?

Known as Gamma-Amino Butyric acid, it is an amino acid that performs functions of neurotransmitters in the brain.it is the most abundant neurotransmitters occurring in the central nervous system (CNS).it  acts as an inhibitor of transmissions in the brain thus in the process calming down activities in the nervous system. It is found as a supplement in which it acts as a natural tranquilizer. It has been shown to increase levels of human growth hormones thus is very popular among body builders.

The Neurotransmitters Question

The brain is made up of millions of cells. Communication takes place from one brain region to another through neurotransmitters. Neurons are individual cells of the nerves that make up the nervous system. They serve as the wiring for the body to transmit information form one region to another. The electrical signals generated are transported through the neurons as a single impulse. Ones the impulses reaches the end of the neurons, it is transmitted to the other cell through neurotransmitters.

The central nervous system consists of the spinal cord and the brain. The two consist of neurotransmitters which pass from one end of the neuron to another. The peripheral nervous system which is made up of nerves that run to the rest of the body. The nerves transmit chemical signals from one neuron t adjacent gland cells and muscles.

GABA and glutamate are the most abundantly occurring neurotransmitters in the nervous system. The two are in abundance in the cerebral cortex which is the region where interpretation of sensation takes place and thinking occurs. The ending of the neurons are made up of sac like structures which are filled with neurotransmitters.

GABA

When the chemical and electrical signals reach the end of the neurons, they trigger the sacs to release neurotransmitters to act as a bridge between one nerve cell and another. The spaces called synapses act as a bridge through which signals pass to the other cells. On reaching the other neuron, the neurotransmitters attach to the cell receptors. This triggers the electric impulse to move from the end of the nerve cell neuron to the other cell completing the message transmission and triggering and effect.

Role of GABA In the Brain

It is formed in the cells of the brain from glutamate. GABA acts as an inhibitory neurotransmitter which simply means that it blocks nerve impulses in the brain. On the other hand, glutamate from which GABA is formed is an excitatory neurotransmitter. When it binds to cells adjacent to it, it activates them to send impulses throughout the brain from one cell to another. GABA instead of telling the brain to activate and send impulses, it tells it he opposite. It stimulates the brain not to send nerve impulses from one cell to another.

In the absence of GABA nerve cells tend to activate more often sending signals regularly. Disorders associated with anxiety such as headaches, addiction, panic attacks, Parkinson syndrome, cognitive impairment and seizures are all linked to low activity of GABA.

It naturally hinders nerve impulses transmission from one cell to another. It brings about a calming effect in the process. The best way to understand the significance of GABA is by understanding the effects of caffeine on the brain. Caffeine acts as an inhibitor of the release of GABA. When the levels of GABA are low in the brain, more nerve transmissions take place. This leads to the sensational feeling that one gets when they takes coffee. This feeling is as a result of activity of glutamate with less GABA.

The reason why, caffeine does this is simply because other molecules tend to bind with the neurons near the site where GABA binds with these neurons. This is exactly the way that basic tranquilizers like barbiturates and Benzodiazepines work. They increase the effects of GABA in the body which in turns inhibits the transmission of nerves.

GABA Metabolism

It is synthesized in a metabolic path known as the GABA shunt. The first step in GABA formation uses a-ketoglutarate that  is formed from metabolism of glucose in the Kreb’s cycle. Afterwards a-ketoglutarate is processed by a-oxoglutarate to form glutamate. In the final process, the glutamate undergoes decarboxylation to form GABA through the glutamic acid decarboxylase enzyme. Like other neurotransmitters, GABA is stored in the synaptic vesicles of the brain and is only released when depolarization of the presynaptic membrane takes place.

GABA

GABA and Addiction

Alcohol consumption leads to loss of coordination of the motors as well as sedation as other high levels of inhibitory transmitters do. Studies therefore show that GABA effects contribute to some effects of alcohol in the brain. Past studies show that, GABA as an inhibitory neurotransmitter is affected by alcohol consumption. Continuous alcohol consumption leading to addiction lead to decline in GABA receptors found in the brain and his reduces the ability of the neurotransmitter t bind with cell receptors.

In this case, the body is forced to find ways to compensate for the declined levels of GABA neurotransmitters. These effects are responsible for brain function changes that lead to things like dependence and alcohol tolerance. When one withdraws from alcohol, the stimulating effects on the neurotransmitter disappear. The body has very few GABA receptors needed to balance the effects of excitatory neurotransmitters. Because of this the brain has too many excitatory nerve signals being transmitted. This translates to psychological and physical effects of alcohol addiction and withdrawal.

Methylation and Addiction

February 6, 2015

The Mechanisms in Methylation and Addiction

Addiction refers to a very strong need to take something like drugs or do particular activities. Addictions are so strong that people think they have no control over them. Addiction becomes one of the important things in your life. Due to this it ends up affecting the quality of your life as well as your relationship with others.

Addiction occurs when one feels they should take something like drugs or alcohol or carry out a particular activity such as gambling. Today addiction affects people across all ages. There is no known reason why people get addicted to something. However, regular intake of drugs or gambling may result in the person’s life getting tuned to that particular choice. People get strongly attached to these things and they feel the need to repeat the same thing over and over again. This way they become addicted to that thing and it becomes an important part of their life.

What is methylation?

Methylation basically refers to the process of adding a methyl group to a substance or simply replacement of an atomic group with that of a group of methyl. It is takes place where a methyl group undergoes alkylation instead of the normal hydrogen atom replacing a carbon chain. Such terms apply in biochemistry, chemistry, biological sciences as well as soil science.

Methylation and Addiction

In biological sciences for instance methylation involves the enzyme catalyzation. This form of methylation is responsible for heavy metal modification, gene expression regulation, processing of RNA as well as regulation the functioning of proteins in the body. Heavy metal methylation often takes place outside the biological system. Reduction of histological staining is made possible by the chemical methylation of tissues in the body.

Methylation in the body

It is one of the important processes that take place in the body.  It takes place when the body receives a substance and converts it to another. This is basically so that the substance can be removed from the body. Methylation takes place in the liver during the second detoxification phase a billon times per second.

In order to understand detoxification, there is need to look at what makes up a methyl group. A methyl group is basically made up of three atoms of hydrogen. Methylation takes place when S-adenosine methionine (SAMe) gives out a methyl group that is then attached to the molecule that undergoes detoxification.  The SAMe s then converted to homocysteine. The methylation process must occur often in order to detoxify the body regularly. Buildup of toxics in the body leads to poisoning of cells which can lead to serious medical conditions a like inflammation and cancer. The methylation process is kept going by vitamin B12, B6 as well as folic acid. These substances are necessary in the body in order to facilitate homocysteine reduction to facilitate the process of methylation.

Homocysteine is an amino acid that is naturally toxic to the body. If left to accumulate it can prove toxic to the cells leading to several health conditions. If methylation does not take place as it should a person can suffer from conditions like stroke, cancers of the reproductive system, colon cancer, Alzheimer’s disease, heart disease, defects of the neural tubes, impairment in DNA repair, kidney infarct, impaired detoxification and dysplasia among others.

Faulty methylation leads to the levels of homocysteine increasing. This leads to poisoning of the cells and tissues. However, studies show that B vitamins facilitate lowering of the levels of homocysteine in the body and therefore reducing the risk of a person getting disease like stroke and heart attack.  Common belief among people is that the main cause of heart attack is in accumulation of cholesterol in the body therefore they cut out their intake of cholesterol in their foods. However, studies show that only a fraction of people who suffer from heart attacks is as a result of cholesterol build up in the body. This being the case, other people who suffer from heart disease may be because of buildup of homocysteine in the body.

Methylation and Addiction

Methylation and Addiction

Recent research studies show that over exposure to certain drugs facilitates chances in methylation levels in the bloods. The same also promotes DNA methylation levels to be altered. DNA methylation takes place in the brain neurons. The altered level of methylation promotes altered levels in gene expression this can happens when one is addicted to certain substances like drugs and alcohol.

Basically methylation is used in DNA. Naturally, each cell in the body contains DNA of other cells. Methyl groups that occur naturally in the body are responsible from suppression of DNA that should not be read. When there is poor methylation due to an addiction to drugs or alcohol, the methyl groups are removed from the genes in order to be used in other body processes. This removal of a methyl group is what leads to cancer expression in the body.

NAC, the Cystine-Glutamate Antiporter and Addiction

Addiction is one complex problem faced by many. There is no limit to how many things people can get addicted to. If you cannot go a day without watching a movie, and then it gets to a point when you must slot in a couple of hours in your daily schedule to watch movies then that is your addiction.

If you keep getting those cravings for soda or sugary meals, you try to stay without them but the urge is so much that you only calm down after satisfying that thirst then that is an addiction.

Addiction can be good or bad. You can be addicted to work, you love your work that you can’t spend time away from your job. That is addiction. Such positive addictions too may be unhealthy. If you are addicted to work for instance, you will hardly spare time for other essential activities, such as being with your family.

Other forms of addiction often associated with the term, such as drug and substance abuse are detrimental to your health. A person who is addicted to alcohol for instance cannot live without it. Their lives often revolve around the liquor. The same applies to coke, cigarettes, marijuana and all other recreational drugs. The substance of addiction gets to dictate how you live your life.

Facts about addiction

The habit is a problem. You have to first admit it in order to be able to get over it. An addict who finds it difficult to get over the problem may often be tempted to blame it on someone, or something else. But that is not a solution, acceptance is key.

Giving in to one’s yearnings is a matter of choice. At the beginning of any addiction you often see yourself in control of the situation. You are not forced to do anything, you just do it because you enjoy the act. With time though, this control diminishes and you become increasingly more vulnerable to the substance of your addiction.

You are in a position to drop your addictions by saying ‘no’ to the substance. This is the premise under which psychosocial support for addiction recovery is usually built. Through guidance one is offered a way out of their drug or substance habit. At such point, it is upon you to decide whether or not you are going to adopt a clean lifestyle.

 

NAC and Addiction

N-Acetyl L-Cysteine is a chemically changed version of the non-essential amino acids in the body. NAC works by purifying your body by removing harmful toxins. It is highly essential in recovery from drug addiction. alcohol and other drugs commonly abused cause a lot of damage to the liver, lungs, kidneys and other organs and this is likely to result in chronic ailments that are life threatening.  This amino acid is essential as it protects cells from getting damaged in addition to its role in preserving functions of the liver.

It is a known precursor to Glutathione which is the most effective in destroying free radicals. The amino acid works to protect the brain and the liver from damages caused by toxins like alcohol, acidic mater, particles found in the air and cigarettes smoke. It also has other significant functions that are key to the wellbeing of an individual.

Among them, it helps the body to promote its burning of fat and aids the muscle building process. Studies also indicate that it can rid the body of copper by a chelating effect, and is used in the treatment of particular diseases including bronchitis, emphysema and certain respiratory problems among adults.

NAC plays a key role in the production of white blood cells necessary for body immunity. The white cells fight diseases that attack the body and help boost the natural immune response of the body. As such, the amino acid is essential for the defense of the body against disease attack.  It further helps in insulin metabolism and functions, which is key to the body’s blood sugar regulation.

the Cystine-Glutamate Antiporter

Sources of NAC

N-Acetyl L-Cysteine can always be naturally manufactured by the body on its own. The high-protein foods such as eggs and meat are however potent dietary sources of this amino acid. Other good sources include foods such as broccoli, garlic, wheat, onions and red peppers.

Other sources that can be recommended for this important amino acid for those who are recovering from the damage caused by drug addiction include nutritional supplements found in a number of nutrition outlets in different continents. It is however important to seek recommendations form a physician since this product is largely unregulated and health consumers are likely to purchase a product that contains incorrect amount of ingredients recommended for the particular patient.

Fibromyalgia and NAD Treatment

January 28, 2015

Fibromyalgia and NAD Treatment

There is often a thin line between chronic fatigue and fibromyalgia. The two conditions exhibit almost the same symptoms. Many are the times when patients suffering from chronic fatigue syndrome have been diagnosed and treated for fibromyalgia.

So what is fibromyalgia? It is a health disorder that is often characterized by intense and widespread pain in the muscles. These pains are accompanied by other symptoms like increased fatigue, insomnia, mood swings and impaired memory and concentration levels. Studies show that the intense pains in patients with fibromyalgia is as a result of manipulation of the way pain signals are processed by the brain.

The symptoms of this disorder begin to manifest themselves after an individual has undergone a major stressful situation, physical trauma, infection or surgery. In some other cases the symptoms will continue building up over a period of time.

Contrary to many beliefs that fibromyalgia is a disease of the old folks, the condition can affect anybody from the young to the old. However, women are more at risk of developing the disease as compared to men. This is probably because women are more exposed to psychological stress than men.

Fibromyalgia

Most people who are diagnosed with the disease suffer from conditions such as temporomandibular joint disorders, anxiety, irritable bowel movements, headaches as well as depression. While fibromyalgia remains without a cure, the patients are given medications which aim at controlling the symptoms. Also some physiological measures such as relaxation, exercises and reducing the amount of stress you are exposed to also help ease the situation.

NAD Treatment for Fibromyalgia

Some of the symptoms of fibromyalgia are like those of chronic fatigue syndrome. NAD treatment is one that is used on patients suffering from this condition.

Basically we all need energy to survive. Every process in our bodies relies on energy and that is what keeps us healthy from circulation, breathing to even digestion. The mitochondria are responsible for generation of energy used by cells to perform their functions. Without this energy we are prone to diseases and medical conditions like chronic fatigue and fibromyalgia.

Nicotinamide adenine dinucleotide (NAD) refers to a molecule whose function is to react with the oxygen found in the mitochondria. This reaction creates energy that is used by the cells to help you in breathing, movement, food digestion, blood pumping and thinking.  In short, this energy is what enables to live your life as it is.

Studies show that lack of this molecule is what causes chronic fatigue, fibromyalgia, anxiety, depression, weakening of the immune system, impaired memory and decline in concentration levels, sleeping problems, muscle aches and weakness and even drug and alcohol addictions. Deficiency in this molecule is a cellular disease epidemic that may go undetected.

How Does NAD Works?

NAD is basically and active form of vitamin B3. NAD is converted into a co-enzyme that binds with hydrogen to become NADH. Hydrogen combines with oxygen in the body to generate energy. Naturally when hydrogen and oxygen react in their liquid forms they generate energy like in the case of hot air balloons. This same reaction takes place in the body.

However due to the explosive power of hydrogen, during NAD treatment it must be carefully inserted into the NAD molecule so that it can generate energy for the body without causing harm to the patient. NAD in this case acts as the hydrogen carrier before it reacts with the oxygen to become NADH.

The process of converting NAD into NADH undergoes through a cycle called Citric Acid Cycle. The fats, carbohydrates and proteins that we eat in our diet provide the necessary chemicals that enter into the cycle. At this point the NAD molecule becomes loaded with the hydrogen which enters into the mitochondria generating a reaction with oxygen that ends up generating energy.

Fibromyalgia

The energy produced by this reaction in the mitochondria is in form of ATP and also a bit of water. The ATP is what is used by the body to assist in blood pumping, contraction of muscles and also the energy that is required by billions of cells in the body.

It is clear how important energy is for normal body function. The energy produced is utilized by body organs like the heart and brain. When there is a deficiency in the energy production the brain is the first organ that is affected. This leads to decline in concentration, memory problems and reduced attention.

If incase this shortage of energy lasts a bit longer, the brain is unable to produce neurotransmitters such as dopamine, serotonin and noradrenaline which are useful in maintain consciousness. We thereby start experiencing depression, anxiety, moods swings and lack of sleep.  It is afterwards that the muscles begin to ache and fatigue creeps in because processes like blood pumping have reduced.

At AwareMed we believe in health and wellness and genera body health. Dr. Dalal Akoury will provide more information about this topic and more. Just visit www.awaremednetwork.com today and she will answer any questions you may have about Fibromyalgia and other health conditions.

Can Dopamine Depletion Cause Cocaine Addiction

January 20, 2015

Research Shows Dopamine Depletion Causes Cocaine Addiction

Dopamine depletionThe importance of dopamine in our bodies can never be underestimated. This is one of the most crucial neurotransmitters in the body. Dopamine has very many functions in the body but to many people it is famous for its good feeling effects that it is always identified with but this should not be the case as it has functions beyond the mesolimbic pathway. In the brain dopamine plays such roles as: It plays a big role in starting movement, and the destruction of dopamine neurons in an area of the brain called the substantia nigra is what produces the symptoms of Parkinson’s disease. Dopamine also plays an important role as a hormone acting to inhibit prolactin to stop the release of breast milk. Back in the mesolimbic pathway, dopamine can play a role in psychosis, and many antipsychotics for treatment of schizophrenia target dopamine. Dopamine is involved in the frontal cortex in executive functions like attention. In the rest of the body, dopamine is involved in nausea, in kidney function, and in heart function.

For emphasis, dopamine isn’t only associated with good feelings but in itself has many functions. This neurotransmitter is involved in many different important pathways. However, most people can only identify dopamine with such aspects as motivation, addiction, attention, or lust, their knowledge of dopamine is limited to the mesolimbic pathway. It is a pathway which starts with cells in the ventral tegmental area, buried deep in the middle of the brain, which send their projections out to places like the nucleus accumbens and the cortex.

Whenever a person engages in any pleasurable activity like sex, use of drugs or partying the brain will respond by increasing the levels of dopamine released in the nucleus accumbens .However during addiction the dopamine signaling in this area is changed. For any drug to have any pleasurable feeling to the user then the level of dopamine must be increased and this is what causes euphoric feelings that drug users will do anything to achieve.

Cocaine abuse and dopamine surges

Cocaine is one of the drugs of pleasure that are largely used even today despite its unpleasant effects on the user. Cocaine abuse is known to trigger large surges of dopamine extracellular in limbic areas, specifically, nucleus accumbens. Researchers have shown that human imaging studies correlate descriptors of reward, for instance, the “high” and euphoria with cocaine induced increases in dopamine nucleus accumbens. There is also the issue of saliency of the reward, which seems to be driven by the novelty or unexpectedness of the activity. It is the euphoric properties of cocaine that lead to the development of chronic abuse, and appear to involve the acute activation of central dopamine neuronal systems. This is based upon known effects of cocaine on dopamine neurons, and the role played by dopamine in reward states and self-stimulation behavior. When a person uses cocaine for a long time his neurotransmitter and neuroendocrine alterations will eventually occur. Dopamine depletion is hypothesized to result from overstimulation of these neurons and excessive synaptic metabolism of the neurotransmitter. It is this depletion of dopamine that may underlie dysphoric aspects of cocaine abstinence, and cocaine cravings.

Some scientists have opined neurochemical disruptions caused by cocaine are consistent with the concept of physical rather than psychological addiction. Possible pharmacological interventions in cocaine addiction are outlined and the psychological approach to these patients is discussed. With many research findings on cocaine relations with dopamine, it is clear that cocaine addiction stems from the depletion of synaptic dopamine in the mesolimbic dopamine reward system, leading to a dysphoric withdrawal state that drives cocaine seeking to restore dopamine to normal, drug-naïve level.

Owing to its euphoric feelings, people who use cocaine find it hard to quit. When your brain has been conditioned to produce high levels of dopamine only when you are using cocaine then it will be hard for you to quit using this drug as every time you try to quit all the withdrawal symptoms, some of which may be too severe sets in and that ties a person to cocaine abuse thereby causing addiction and dependence thereafter. These cravings contribute not only to addiction but to relapse after a hard-won sobriety. A person addicted to cocaine may be in danger of relapse when he interacts with the people he used to take it with. These triggers do something to his brain that awakens his cravings for cocaine.

Dopamine depletionUsing dopamine antagonists to treat cocaine addiction

Today there is evidence that cocaine exerts its rewarding effects through the acute activation of dopamine pathways in the brain. Chronic cocaine administration is hypothesized to lead to dopamine depletion, which results in cocaine craving and cocaine abstinence states. This is a condition that has chained many to cocaine use but there is hope as treatment of cocaine addiction with bromocriptine which is a dopamine antagonist has been found to be effective in quelling all the cravings associated with cocaine addiction.

Drug addiction is a vice that should be fought by all means that is why we at AWAREmed Health and Wellness Resource Center are committed to availing help to addicts and offering them a place to call home. We offer NER Treatment and Amino acid therapy that are the most effective approaches to addiction treatment and recovery. You call on Dr. Dalal Akoury (MD) today and begin your journey to victory against addiction.
