Physiological Dependence Harmony Treatment and Wellness

7In addition, a functional cross-talk between the endocannabinoid and opioid systems has been found in the mutual modulation of drug/alcohol reinforcement and reward processes . B), it has been shown that social attractiveness , sex and orgasm , even classical music (but only in musicians; Ref. 51) can induce enhanced activity in the NAC. Also, a variety of drugs abused by humans, including alcohol, leads to enhanced mesolimbic DAergic activity, preferentially in the NAC shell region . In the following text, animal studies are described that examine the relationship between alcohol and midbrain DA. The ability of fruit flies to detect ethanol is important for chemotaxis towards food sources. However, adult flies are also susceptible to intoxication and death in high ethanol environments , in a range similar to that observed in humans, making them an ideal animal model for the study of alcohol intoxication . In conclusion, there is a selective advantage in the ability of fruit flies to avoid environments with dangerously high alcohol concentrations, and LUSH is required for this response. The main reasons for the consumption of alcohol are that it can produce positive mood states and has stress-relieving effects. Thus alcohol is a daily incentive and, in addition to coffee and tea, alcoholic beverages are the most important commodities worldwide. In fact, Europeans spend ∼100 billion euros on alcoholic beverages annually, which is reflected by the high rate of alcohol consumption per capita of 10 liters of pure ethanol per year.

It is currently unknown whether other neuropeptides involved in feeding behavior also modulate the action of ethanol on DAergic neurons. Such neuropeptides may include orexin A and B, which are synthesized exclusively in neurons of the lateral hypothalamus and are activated in response to natural and drug reinforcers including alcohol . In addition, stimuli conditioned to alcohol availability also activate hypothalamic orexin neurons . Since there is a lateral hypothalamic orexin projection to both the VTA and the NAC , it is probable that ethanol has an access point to the mesolimbic reinforcement system via these neuropeptides. Various techniques have indicated that the mesolimbic DAergic system is activated when alcohol is administered to laboratory animals. With the use of microdialysis, it was found that acute administration of alcohol results in preferential release of DA from the NAC shell region . It is suggested that the manner by which acute alcohol administration increases extracellular DA within the NAC is via changes in GABAergic feedback into the VTA.

Hard use, where the drug is central in the user’s life, and soft use, where it is merely incidental, are terms of assistance in making this distinction, i.e. what is classified is not the drug but the effect it has on, or the way it is used by, the individual. The term ‘recreational’ is often applied to such use, conferring an apparent sanction that relates more to the latter category.

Is There an Overlap Between Psychological and Physical Addiction?

In this study the magnitude of the change in raclopride binding correlated with the psychostimulant effects of alcohol. This indicates that enhanced DA release occurs in response to alcohol drinking and that the degree of psychostimulation is mediated, at least in part, by augmented extracellular DA levels. Multiple signaling pathways activated by alcohol and possibly by its metabolites lead to alterations in gene expression . As a consequence of repeated alcohol intake, more or less long-lasting cellular and neurophysiological changes that trigger alcohol-seeking behavior become apparent in the brain reinforcement system. Whether or not this behavioral response transforms into an addictive behavior finally depends on the genetic make-up of an individual, as well as on numerous environmental factors (Fig. 2). When a person enters treatment for drug or alcohol addiction, the first step is typically to detox from drugs and/or alcohol. During detox, the goal is to completely remove drugs and alcohol from the person’s system. When a person goes “cold turkey” like this, they usually experience physical withdrawal symptoms, which is a sign of physical dependence. Physical withdrawal symptoms tend to follow a timeline, and although they can vary in severity, health care professionals and addiction specialists generally know what to expect when an individual is undergoing detox. Alcohol and drug addiction treatment should include approaches for both physical and psychological dependencies.

This alters the way your brain sees pleasurable experiences, ultimately replacing healthy activities with using drugs or alcohol to feel good. The brain is significantly impacted by addiction.Research has found that long-term use of drugs or alcohol can cause physical changes in the brain, in addition to changes in the way hormones and neurotransmitters, are used by the body. Changes in the brain can affect your mood, memory, thinking, and behavior, as well as the way your organs function. Factors that might put one at higher risk for psychological dependence include past exposure to violence, environmental stressors, anxiety, or other mood disorders. Personality variables, such as neuroticism, low self-control, low self-regulation, low self-esteem, or loneliness can also be factors.

A person can have a psychological dependence on a drug or certain behaviors or activities. A person may become addicted to skydiving or other behaviors because of the adrenaline rush. The adrenaline rush releases the same chemicals in the brain that make a person feel euphoria. Other behaviors may include gambling, playing video games, extreme sports, and any activity a person becomes dependent on. When the behavior stops, the person has similar symptoms to drug and alcohol withdrawal but without the physical symptoms. The person who has a psychological dependence will seek out the behavior or activity that made them feel happy or content. Tolerance and psychological and physical dependence may occur following prolonged use of BZDs. Such effects may occur following short-term use of BZDs, particularly at high doses.
This further demonstrates interactions with the mesolimbic DA system as well as DA-independent processes. In this respect, the hypothalamus, which interfaces the brain-body axis, may prove to be of importance. Besides the NMDA receptor, other receptors or ion channels expressed within the CNS also have putative alcohol-binding sites. The GABAA receptor/chloride channel complex is a pentameric ligand-gated ion channel and the major inhibitory neurotransmitter receptor in the mammalian brain. Several subunits have been identified, with the majority of GABAA receptors being composed of α-, β-, γ-, and δ-subunits . In addition to its effects on GABAA receptors, ethanol also directly affects glycine receptors.

People who have a family history of psychological dependence can also be at risk. Your body is always doing its best to maintain equilibrium, and excessive use of substances changes this. There comes the point when your body doesn’t know how to function without your substance of choice. When the drug or alcohol begins to metabolize, you start to experience the harsh symptoms of withdrawal. The symptoms of withdrawal vary from drug to drug as well as the people experiencing withdrawal. Physiological dependence on alcohol and drugs is the first thing to acknowledge when getting clean. Many people have the idea that they can quit on their own, but this can be extremely dangerous. Not only is this one of the leading reasons for relapse, but it can also put your life at risk.

Subsequently, the activity of adenylyl cyclase , through coupling to stimulatory G proteins (Gαs), results in an increase in cAMP concentration and in the activation of cAMP-dependent protein kinase A signaling. CAMP induces this activation by promoting the dissociation of the regulatory subunit physiological dependence on alcohol of PKA from the catalytic subunit (PKA-Cα). PKA-Cα then leads to phosphorylation of the transcription factor cAMP response element-binding protein . Exposure to ethanol also influences the expression of Ca2+/calmodulin-dependent protein kinase IV and thereby CREB phosphorylation in the NAC.

The main glucocorticoid in humans and other primates is cortisol; the main glucocorticoid in rodents is corticosterone. In addition to physical signs of withdrawal, a constellation of symptoms contributing to a state of distress and psychological discomfort constitute a significant component of the withdrawal syndrome (Anton and Becker 1995; Roelofs 1985; Schuckit et al. 1998). Many of these signs and symptoms, including those that reflect a negative-affect state (e.g., anxiety, distress, and anhedonia) also have been demonstrated in animal studies involving various models of dependence . It is characterized by the inability to stop using a certain drug to the detriment of work, social, or family obligations. The latter reflect physical dependence during which the body adapts to the drug of choice, requiring more and more of it to achieve a certain effect. It also elicits drug-specific physical or psychological symptoms if drug use is abruptly ceased. Physical dependence is generally thought of as the body’s response to withdrawing from drugs or alcohol.

C. A Perspective of Systems-Oriented Alcohol Research

Believing the person can relinquish the substance at any time is another social symptom of an addict. The reason for wanting to be alone can be because of shame or just the substance taking over one’s life. To combat addiction, it would be helpful to have loved ones help you overcome and be a part of your recovery life. These risks can include trading sexual favors for the substance and even stealing to get your substance. The inability to stop using drugs even after health problems arise is another symptom of psychological dependency versus physical dependency. Here at Sana Lake, we offer several programs that can help each patient individually. Insomnia or lack of sleep is another physical addictive dependency attribute versus the psychological dependency attribute.

The role of corticotrophin-releasing factor in stress-induced relapse to alcohol-seeking behavior in rats. Repeated cycles of chronic intermittent ethanol exposure in mice increases voluntary ethanol drinking and ethanol concentrations in the nucleus accumbens. Knapp DJ, Overstreet DH, Breese GR. Baclofen blocks expression and sensitization of anxiety-like Sober Home behavior in an animal model of repeated stress and ethanol withdrawal. Also, physical dependence can occur without addiction—this is the common experience for many chronic pain patients who continue to take their opioid medications as prescribed for an extended period but don’t experience unmanageable compulsions or a loss of control.

However, it is too premature to state whether epigenetic alterations with the α-synuclein gene constitute a molecular switch for lasting maladaptations in the brain. Nevertheless, these findings exemplify that studies on epigenetic effects induced by chronic alcohol exposure may be promising in identifying molecular mechanisms underlying addictive behavior. As discussed in the next chapter for the synaptic and cellular levels, it has however been claimed by some researchers that long-lasting alterations in synaptic plasticity have been identified that may underlie addictive behavior. The role of DA in mediating alcohol reinforcement has also been studied in the human brain. In an initial report by Ahlenius et al. , it was shown that α-methyl-p-tyrosine, a compound that blocks DA synthesis, decreases ethanol-induced psychostimulation in humans. Using positron emission tomography measurements, Boileau et al. demonstrated a significant reduction in raclopride binding in the NAC in healthy volunteers after alcohol ingestion.

When you stop using the substance, you experience physical symptoms of withdrawal. Enhanced negative emotion and alcohol craving, and altered physiological responses following stress and cue exposure in alcohol dependent individuals. The CRF1 receptor antagonist antalarmin attenuates yohimbine-induced increases in operant alcohol self-administration and reinstatement of alcohol seeking in rats. As previously noted, increased anxiety represents a significant component of the alcohol withdrawal syndrome. Importantly, this negative-affect state may contribute to increased risk for relapse as well as perpetuate continued use and abuse of alcohol (Becker 1999; Driessen et al. 2001; Koob 2003; Roelofs 1985). Indeed, both preclinical and clinical studies suggest a link between anxiety and propensity to self-administer alcohol (Henniger et al. 2002; Spanagel et al. 1995; Willinger et al. 2002). Zhang Z, Morse AC, Koob GF, Schulteis G. Dose- and time-dependent expression of anxiety-like behavior in the elevated plus-maze during withdrawal from acute and repeated intermittent ethanol intoxication in rats. Examples of withdrawal symptoms include hand tremors and gastrointestinal issues.

Acknowledging the pain and finding the professional help to alleviate it and begin the appropriate therapies are essential first steps in recovery. Psychological dependence, on the other hand, is treated using behavioral therapies, holistic therapies, and support groups. The goal of these treatments is to help patients identify harmful thoughts or behaviors and replace them with healthier coping mechanisms. These therapies may be held on an individual or group basis but should be individualized to meet each patient’s unique needs. Although detox usually lasts less than a week, addiction treatment programs might last anywhere from 30 days to several months depending on the severity of a person’s symptoms. Before physical dependence forms, the afflicted individual begins building a tolerance on their substance of choice. Tolerance refers to the phenomenon that occurs when people abuse mood or mind-altering substances so often that their body adjusts to having the substance in the body. As a result, someone who used to get high off taking one pill will need to take increasing amounts of the drug to achieve the desired effects. Tolerance works the same way with alcohol – someone who used to get drunk off of three beers may now need to drink hard liquor in larger amounts in order to get drunk. Scientifically speaking, physiological dependence describes the adaptive changes the body makes in response to the continued use of an addictive substance.
