Methamphetamine Use May Risk Development of Parkinson’s Disease

March 25, 2015

Methamphetamine Use May Predispose Consumers to Future Development of Parkinson’s Disease

There are several neurodegenerative disorders but it will still not be right for anybody to talk about neurodegenerative disorders without mentioning the Parkinson’s disease. This disorder is the second most common after Alzheimer’s disease and it is affecting approximately ten million people worldwide. The probability of a person suffering from this disease increases with age with most people being diagnosed after the age of 50. Early in the course of the disease, the most obvious symptoms are movement-related. These include shaking, rigidity, slowness of movement, and difficulty with walking and gait. However, the symptoms worsens as time passes by, these may include cognitive and behavioral problems with dementia commonly occurring in the advanced stages of the disease. Other symptoms include sensory, sleep, and emotional problems. PD is caused by degeneration of midbrain dopaminergic neurons that project to the striatum. The loss of striatal dopamine is responsible for the major symptoms of the disease. Although a small proportion of cases can be attributed to known genetic factors, most cases of PD are idiopathic. While the etiology of dopaminergic neuronal demise is mysterious, a combination of genetic susceptibilities, age, and environmental factors seems to play a critical role. Dopamine degeneration process in PD involves abnormal protein handling, oxidative stress, mitochondrial dysfunction, excitotoxicity, apoptotic processes, and microglial activation or neuroinflammation.

Studies on animals on methamphetamine toxicity

Studies done on animals have shown that methamphetamine can cause long-term dopamine terminal damage as well as dopamine neuronal body loss. In rodents, repeated administration of methamphetamine causes a decrease in dopaminergic markers such as tyrosine hydroxylase (TH) and dopamine transporter. Accompanied by a reduction in TH activity, reduced levels of dopamine and its metabolites and decreased levels of vesicular monoamine transporter 2 (VMAT2). These effects occur primarily in the striatum but also in the cortex, thalamus, hypothalamus and hippocampus. Methamphetamine induces neurotoxicity in a dose-dependent manner as do other amphetamine-derivatives like MDMA. Although partial recovery of TH and dopamine transport fibers occurs after methamphetamine administration, methamphetamine-induced neurotoxicity is persistent. In mice, the greatest dopaminergic fiber loss is seen 24 hours after methamphetamine administration. Neurotoxic effects persist for more than seven days after methamphetamine exposure and one month after MDMA exposure. Drugs that induce PD symptoms and TH loss such as MPTP in mice also show a partial recovery with time in nonhuman monkeys and mice. The time courses and degrees of TH and dopamine transport fiber recovery after methamphetamine or after MDMA exposure are similar, suggesting terminal regrowth, as these two proteins are independently regulated. Researchers have also noted that there is partial recovery of dopamine levels in the striatum strongly suggesting that the regrown terminals are functional. However the mechanisms responsible for partial recovery are not known, but it is speculated that it might involve compensatory sprouting and branching as has been reported for regrowth following MPTP-induced damage. Dopamine terminal recovery has also been described in rhesus monkeys and velvet monkeys, although it appears to occur on a slower timescale than in mice. Methamphetamine-induced dopaminergic damage persists for more than 12 weeks in velvet monkeys and more than 3 years in rhesus monkeys, demonstrating the persistence of methamphetamine-induced brain damage.

Methamphetamine Toxicity in the Substantia Nigra

This drug doesn’t only cause fiber loss in TH but also produces dopamine cell body loss in the substantia nigra as shown in tests in mice that were treated with 3 methamphetamine injections (5 mg/kg) at 3-hour intervals. From the counts it is evident that 20 to 25% dopaminergic cell loss, measured at different time are linked to exposure to methamphetamine. The observed pattern of TH-stained neuron loss is very similar to the pattern of Nissl-stained neuron loss, indicating that neuronal loss is specific to dopaminergic neurons. Dopamine cell body loss was confirmed via staining with Fluoro-Jade, a general marker of neuronal degeneration that fluoresces after administration of known dopaminergic toxins such as 6-OHDA and MPTP. Fluoro-Jade stains scattered neurons degenerated in the substantia nigra after methamphetamine treatment. there is a possibility that the lack of complete recovery of TH fibers in the striatum is related to the loss of dopaminergic neurons in the Substantia nigra similar to what occurs in Parkinson’s disease.

Increased Risk of Parkinson’s Disease in Methamphetamine Abusers

There are literatures that have linked the abuse of amphetamine to the later development of PD. In a report of a study done by Callaghan and his colleagues, there is an increase in of PD in methamphetamine users in an epidemiological investigation based on data from California statewide hospital discharge records. The researchers identified 1,863 methamphetamine users, 9,315 patients hospitalized for appendicitis as a nondrug control group, and 1,720 cocaine users as a drug control group. All subjects were aged at least 50 years, had been hospitalized in California between 1990 and 2000, and had been followed for up to 10 years after discharge. The methamphetamine user group showed an elevated incidence of PD, with a 165% higher risk for development of PD than the patients from the control group. the results have been confirmed by the same group after doing the same research but in a much broader scope; 40,000 people hospitalized for methamphetamine versus 200,000 for appendicitis and 35,000 for cocaine and a 16-year follow-up period. From these two studies it is evident that methamphetamine use increases the chances of PD development in adulthood.

Drug abuse, addiction and independence are problems that people grapple with every day. These problems need to be treated effectively through integrative medicine. Dr. Dalal Akoury (MD) is an expert at this.  Call her on (843) 213-1480 for help.

Herbs For Pain and Addiction Treatment

March 24, 2015

Use of Jamaican Dogwood, Valerian, Wood Betony, Yellow Jasmine in Pain and Addiction Treatment

Addiction is still one of the major problems that we are still living with today. Though known for its devastating effects, addiction has still remained when of the many menaces that our youths as well as the older generation alike are still glued to. However there is a bitter reality that you need to be aware of, a reality that none of your already addicted friends will let you know of; the journey to addiction treatment and recovery is that which is not easily won. There are serious hurdles that you shall have to meet along the way as you fight on to reach the greener side of life where the chains of addiction are broken. Just like any other disease there are myriads of ways through which the treatment of addiction can be effected. one is through pharmaceutical ways of treatment and the other through natural ways of treatment that may at times be used alongside the orthodox ways of treatment or as an assortment of various herbs and a special choice of diets that helps restore the damage of drugs on the addict and hence making it possible for the addict to be treated of the illness. On the other hand when pharmaceuticals are used for treating drug addiction the doctors will mostly use a substitute of your drug to satisfy your craving for the drug of abuse you are addicted to. Though this may present a short term solution it still doesn’t let you be free from the drug as you will still continue using a substance that is thought to be less addictive and not so dangerous. However the reality is that this kind of treatment does not address the brain imbalances that an addict suffers after a long term use of a certain drug.

Addiction Treatment

As we have seen in previous articles the part of the body that is adversely affected by addiction to drug abuse is the nervous system. The neurotransmitters like the dopamine and the other crucial ones are literally damaged after a prolonged use of drugs. this therefore calls for a treatment option that will not only focus on ending the craving that addicts have for their substance of abuse but to help restore the whole person back to what he or she was before he got into drug use that has since chained him or her. Most pharmaceutical drugs do not consider this but mostly gear towards treating the symptoms of addiction like depression and anxiety that is normally done with sedatives while the underlying problem; the damage to the nervous system, is left unchanged. Through the years there have been different alternatives to addiction that have since come up and have been found to be effective. An example of these alternative therapies that have shown hope to addicts is the use of stem cell therapy that aims at restoring the damage caused by drugs. Despite the effectiveness of some of these alternatives the use of herbs in addiction treatment is yet to be scrapped off, this is solely because of the effectiveness of some herbs in treating addiction. Here are some of the herbs that can be used to help in the addiction treatment and recovery.

Jamaican Dogwood

Jamaican dogwood is mostly used for pain. It has sedative effect, reduces muscle spasm and cools nerve pain. It also reduces inflammations. It has often been the top choice for relieving nerve pain and it has been proved to be powerful in pain management.  It is derived from the bark of the dogwood tree, and can be taken in capsule or tincture forms as well as a tea from the bark’s powder.  Though known for pain management it can contribute in help with addiction as when used it helps to calm down the nerves and relive an addict off the withdrawal effects like depression and anxiety that most of the times can lead to relapse. However beneficial it is it can be potentially dangerous when used for self-medication. It is therefore safe to use it with instructions from an integrative addiction doctor as it is irritant and can cause numbness, tremors, salivation, and sweating.

Wood Betony

Wood Betony

This herb is commonly found in Europe. This plant is rich in medicinal properties. To begin with the fresh, undried leaf of wood betony is a natural pain reliever. This analgesic is good for addiction as it helps in calming the nerves as well as fighting some common symptoms of addiction like depression anxiety and insomnia.

Valeria

Valeria has great sedation properties. As have been revealed by past literature, Valeria has great influence on the cerebro-spinal system. In a recovering addict this herb can be used to promote nerve relaxation and sleep. Insomnia is a common symptom that most addicts battle with, with valerian a recovering addict can be helped evade the grave effects of insomnia and anxiety. It does this by exerting an influence quieting and soothing in its nature upon the brain and nervous system. Other herbs that have been found to be helpful in the journey of addiction treatment and recovery are; Yellow Jasmine, St. Johns worts and chamomile among others

Finally, Here at AWAREmed Health and Wellness Resource Center we are committed to availing help to addicts by availing some of the most integrative approaches to healing an addict. We advocate for natural healing to all kinds of addiction. Call on Dr. Dalal Akoury (MD) at Myrtle Beach, South Carolina for help.

How Profitable Is It To Create Natural Addiction Clinics?

March 23, 2015

There are lots to benefit from when an addict decides to get treatment from a natural addiction clinic. To begin with, most of these natural addiction clinics are also holistic meaning they not only focus on treating the symptoms of addiction but focuses on whole person healing that entails correcting all the defects that might have been caused by the prolonged use of the drugs of abuse. This is just another great reason that make addicts go for natural addiction clinics as opposed to pharmaceutical prescriptions that may only address the issues of addiction related symptoms and cravings but will not focus on achieving whole person healing by healing the parts of brains and the entire nervous system that have since stopped coordinating well for optimum health of the addict. The profitability of natural addiction clinics is peaking in some parts of the world while in others it has already climaxed due to the embrace with which the addicts have welcomed the exceptional ability of nature’s healing powers. Today many addiction patients will prefer to get attended to in a holistic rehabilitation center that advocates for natural addiction treatment. This has led to the mushrooming of different natural addiction centers, some of which have stayed till now offering beneficial addiction treatments to addicts while some that sprang up with the sole aim of reaping big profits have disappeared. What does this tell us? Okay, creating a natural addiction clinic can be very profitable but you as a doctor needs to be more concerned with the wellbeing of your patients than your drive to enrich yourself. AWAREmed Health and Wellness and Resource is an example of an establishment that advocates of natural healing as they are holistic, this facility has remained till now because it was created with a mission to avail the best alternative treatments to patients battling some of the most common diseases that patients find a nightmare to treat such as cancer and addiction. This establishment is a living testimony of how profitable an establishment that advocates for natural healing can be profitable when founded on the stones of care and love for patients as well as laced with unending quest to avail better and safer treatment options to patients battling addiction.

Natural addiction Clinics can benefit all addicts

Another reason that has made natural addiction clinics more popular is the fact that these clinics are well equipped and are always founded by integrative doctors who are experienced in addiction treatment and hence know the extent to which specific drugs or substances affect the person and which option of treatments can best yield the much needed result.  the natural addiction clinics employs some of the traditional addiction treatments that are known to be effective and goes a long way in achieving whole person healing as opposed to treatment of just symptoms and calming down some of the common side effects of drug withdrawals like depression and anxiety. There’s no requirement for attending these clinics except that participants must deeply desire sobriety. However, most participants have been through a traditional rehab program and not had the success they desired. Natural addiction clinic programs are considered alternative types of treatment because they don’t follow the traditional model, which focuses on psychotherapy, 12-step programs and other support groups but focuses on all the benefits that can be drawn from the nature’s natural healing powers to help heal an addict with minimal or no side effects at all.

addiction ClinicsThe natural addiction clinics incorporate the use of herbs and specific diets to help restore the balance in the brain chemistry and quell cravings. The natural addiction clinics are not only for those who are addicted to drugs and substances alone but also for those with behavioral addictions like gambling, sex addiction and even pornography.  Natural addiction clinics may offer such services as nutritional counseling, psychiatric support, massage, yoga, Tai Chi, herbal therapies and adventure-based therapies that cater to all manner of addictions, both behavioral and substance related. These centers also have staffs who are vastly experienced in handling addiction cases. They can also customize treatment to suit every patient’s condition belief and preferences all in a bid to restore the mind the body and the spirit. The fact that the natural addiction clinics are home for all addicts further opens great avenues for qualified doctors who opt to create natural addiction clinics.

Another factor that makes natural addiction clinics preferable is the environment in which most of them are located, natural addiction clinics are not mostly established in busy town centers but on the mountains, or by a lake or the ocean. The setting is usually peaceful and idyllic in order to promote healing. Most holistic addiction doctors believe that locating these clinics in such places helps the patients to connect with nature which further helps them to recover even faster.

Offers variety of treatment options

The extent to which a person is affected by drug use will warrant the type of treatment that he gets, it is also good to note that different people will react to a given treatment differently and this is why a specific treatment that worked for a given addict may fail to work for another addict. This is why most natural addiction clinics avail different treatment options that addicts can benefit from. Some of the traditional approaches to healing like meditation are god for an addict but if for some reason you are not comfortable you are often given the freedom to skip the session. It is your determination for sobriety that shouldn’t run out.

Finally, even if creation of natural addiction clinics were to yield supernormal profits, it is good to stay within the focus which is to avail better healing options for all addicts. Dr. Dalal Akoury of AWAREmed Health and Wellness Resource center has championed the use of integrative medicine in healing addicts for years; find her at Myrtle beach, South Carolina.

Striatum Methamphetamine Toxicity

March 22, 2015

Methamphetamine Toxicity in the Striatum

The striatum is a crucial part of the brain. This part of the brain plays very important roles but it can be adversely affected by the use of stimulants and other drugs of leisure. Substances such as cocaine and methamphetamine produce their primary effects inside the brain by boosting the presence of dopamine which is a neurotransmitting chemical that activates the pleasure-producing neurons contained within the limbic system. As stated above the limbic system includes the hippocampus, along with several other brain structures. According to the results of two separate studies published in 2008 in the Journal of Neuroscience and Biological Psychiatry, the presence of either cocaine or methamphetamine alters normal adult neurogenesis inside the hippocampus and damages this region’s ability replenish its neuron supply.  It is no longer news that methamphetamine intoxication causes long-lasting damage to dopamine nerve endings in the striatum. However the mechanisms underlying this neurotoxicity are not yet known but oxidative stress has been linked to it.

Microglia are the major antigen-presenting cells in brain and when activated, they secrete an array of factors that cause neuronal damage. Astoundingly, very little work has been directed at the study of microglial activation as part of the methamphetamine neurotoxic cascade. It has been report that methamphetamine activates microglia in a dose-related manner and along a time course that is coincident with dopamine nerve ending damage. Through tests done on mice scientists have discovered that prevention of methamphetamine toxicity by maintaining treated mice at low ambient temperature prevents drug-induced microglial activation. MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) not only damages dopamine nerve endings and cell bodies but also  causes extensive microglial activation in striatum as well as in the substantia nigra. Contrastingly, methamphetamine causes neither microglial activation in the substantia nigra nor dopamine cell body damage.

Dopamine transporter antagonists do not mimic the effect of methamphetamine on microglia. Hyperthermia, a prominent and dangerous clinical response to methamphetamine intoxication, has been also ruled out as the cause of microglial activation. Together, these data suggest that microglial activation represents an early step in methamphetamine-induced neurotoxicity. Other neurochemical effects resulting from methamphetamine-induced overflow of dopamine into the synapse, but which are not neurotoxic, do not play a role in this response.

Methamphetamine use on the rise despite effects

The use of methamphetamine has been on the rise despite the fact that it is a powerful stimulant drug that has adverse effects when abused as most people do. According to the UN Office on Drugs and Crime reported recently that abuse of amphetamines, including designer drugs such as methamphetamine and 3, 4-methylenedioxymethamphetamine, now exceeds that of cocaine and heroin on a global scale. This presents no sign that its use will decline any soon. Past researchers were able to establish a fact that methamphetamine causes persistent reductions of function in dopamine nerve endings of animals and humans. Methamphetamine neurotoxicity has been under intense study for over 20 years, but still there is much that still remains to be learned about how this dangerous drug causes damage to dopamine nerve endings. The theory that revolves around oxidative stress has been at the top of the speculations. Drug-induced oxidative stress is an attractive construct that can account for many of the effects of methamphetamine on the dopamine nerve ending such as inhibition of tyrosine hydroxylase activity as well as reductions in the dopamine transporter and the vesicle monoamine transporter. This may even be an early event that leads eventually to methamphetamine-induced apoptosis. However, the source of the reactant species that mediate methamphetamine-induced damage is not known.

methamphetamine

Due to their crucial roles they play in mediating the mediating damage to the nervous system, Microglia has attracted considerable attention. Immune like in many ways  these interesting cells become activated by damage and then transmigrate to sites of injury where they can secrete an array of factors  like cytokines, prostaglandins, nitric oxide, and superoxide that are known to have detrimental effects on neurons. However, the role of microglia in methamphetamine-induced damage to the dopamine system has received little attention. In 1994 a researcher, Bowyer and his colleagues noted for the first time that methamphetamine resulted in activation of microglia in striatum of treated rats. These investigators concluded that microglia were increased in response to nerve ending damage and were not apparently a cause of it.  Recently, another research was conducted to give an in-depth analysis of the effect of methamphetamine on striatal gene expression. Numerous genes linked to microglia were activated significantly within hours of methamphetamine intoxication, suggesting the possibility that microglial activation occurs earlier in the methamphetamine toxic cascade than previously thought.

Today there are researchers who are building on the initial analysis of methamphetamine and report the pharmacological characterization of microglial activation by methamphetamine in striatum. As mentioned before, striatum is an area dense in dopamine nerve endings and is known to be targeted for damage by methamphetamine. Microglial activation coincides with the onset of methamphetamine-induced damage in striatum and the extent of this effect is related to the degree of damage to dopamine nerve endings. Numerous nontoxic effects exerted by methamphetamine, such as inhibition of the DAT, increases in synaptic levels of dopamine, activation of D1 and/or D2 DA receptors, and hyperthermia, cannot explain methamphetamine-induced microglial activation.

Finally, this is still a dark area and there is need for more literature so as to establish the mechanism of methamphetamine toxicity on the striatum. Needless to say, Drug abuse, addiction and independence are problems that people grapple with every day. These problems need to be treated effectively through integrative medicine.

Molecular Mechanisms of Methamphetamine Induced-Neurotoxicity

March 21, 2015

Methamphetamine is a stimulant that is also highly soluble in water and affects the CNS most. Categorically it fits in the group of synthetic drugs chemically related to amphetamine but it has more adverse effects on the Central nervous system than the parent compound. Abuse of these illegal psychostimulants has become an international public health problem, with an estimated 14 to 52 million amphetamine-type stimulant users worldwide, exceeding the total number of cocaine abusers and second only to the number of cannabis abusers. This number has continued to rise in spite of the fact that much has been done to publicize the adverse effects these amphetamine related stimulants are linked to. Meth or speed as known in stimulant use circles exists in different forms like powder, tablets and capsules. It can also be found in a purer crystalline form.

It’s dangerous why is it used?

Just like most stimulants or drugs that are known to induce euphoric feelings, methamphetamine is also taken for similar reasons for example; to induce euphoric feelings, increased sense of well-being, increase energy and to calm anxiety. Being a powerful drug its effects are felt immediately after the use but these effects can last for long hours. They may be accompanied by acute adverse effects such as increased blood pressure and heart rate, which may cause irreversible damage to blood vessels in the brain, resulting in cerebrovascular accidents, stroke, and death. Methamphetamine also produces hyperthermia, pupil dilation, flushing, tremors, trismus and bruxism, muscle tension, loss of appetite or anorexia, and loss of pleasure in food intake which further leads to deterioration of the user’s health.

Effects of Methamphetamine

Being an addictive drug, after a prolonged use the users may develop tolerance. It’s most common symptoms after a prolonged use include; temporomandibular joint syndrome, dental erosion, and myofacial pain. Long-term use also produces lack of appetite, weight loss, accelerated aging, nose-bleeding problems, nonhealing wounds, tooth decay and fracture known as “Meth mouth”. Psychiatric symptoms include anxiety, depression, increased aggression, social isolation, psychosis, mood disturbances, and psychomotor dysfunction. Long periods of high consumption can cause paranoid psychosis. Other symptoms of chronic methamphetamine use may also include; deficits in attention, working memory, and decision making. Most addicts are stuck in the use of meth as a result of the withdrawal symptoms which include the following; irritability, fatigue, impaired social functioning, and intense craving for the drug. Researchers have given evidence that the negative neuropsychiatric consequences of methamphetamine abuse are due, at least in part, to drug-induced neuropathological changes in the brain. Although the exact molecular mechanisms of neuronal body loss are not known, there is evidence to suggest the coexistence of different types of cell death, including apoptosis and necrosis ; indicated by the morphology of neurons stained with hematoxylin-eosin.  Growing evidence exhibits that methamphetamine and MDMA induce an increase in lipid peroxidation and DNA oxidation as well as increased levels of oxidative stress markers such as hydroxyl radical producing neurotoxicity. Methamphetamine increases expression of inducible nitric oxide synthase (nNOS)/ neuronal nitric oxide synthase (iNOS ) indicating increased synthesis of neuronal nitric oxide, which combines with superoxide radicals to form peroxynitrite which is a strong oxidant and a major neurotoxin . Induction of nNOS/iNOS by methamphetamine or MDMA  constitutes part of the mechanism of methamphetamine damage, as selective inhibition or genetic inactivation of nNOS and overexpression of cupper zinc superoxide dismutase (CuZnSOD), an enzyme that catalyzes the dismutation of superoxide into oxygen and hydrogen peroxide, prevent methamphetamine neurotoxicity . Even though methamphetamine increases iNOS expression in the striatum , there is no basis for supposing the involvement of glial nitric oxide in methamphetamine-induced toxicity, but it is interesting to note that mice deficient in iNOS have increased resistance to methamphetamine-induced dopamine neuron damage.

methamphetamine

The neurotoxic effects of methamphetamine on the dopaminergic system are accompanied by activation of astroglia and microglia in the same areas  being strongest in the striatum, the area with biggest toxicity. Glial cells are not activated in the nucleus accumbens, which is not much damaged . In mice, glial activation in striatum and in substantia nigra occurs shortly after methamphetamine administration, as indicated by a significant increase in Mac-1 ;a marker of reactive microglia 24 hours after methamphetamine exposure and prominent increases in GFAP ; a marker of reactive gliosis in response to injury occur within a week  after treatment . The extent of these glial reactions correlates with the observed severity of neurotoxicity.

The dopaminergic system is also involved in this toxicity, as demonstrated in various mutant mice in which inactivation of dopamine transport, dopamine D1 receptors or D2 receptors affords a significant protection against methamphetamine toxicity. Administration of THC prevents dopaminergic toxicity after MDMA, a similar amphetamine derivative to methamphetamine, by CB1 receptor stimulation which is present in striatal medium spiny neurons. All these receptors are involved in different aspects of learning processes that became affected by the chronic use of methamphetamine or MDMA.

Finally, Drug abuse, addiction and independence are problems that people grapple with every day. These problems need to be treated effectively through integrative medicine. Dr. Dalal Akoury (MD) is an expert at this.  Call her on (843) 213-1480 for help.
