When being asked, the difference between physical dependence versus psychological dependence, trembling might come up as a symptom of physical dependence. Yes, there is a difference between physical dependence versus psychological dependence. Psychological dependence is the dependence on the drugs or the substance of choice. When you’re experiencing psychological addiction, your thoughts may be consumed with when you’ll use drugs or alcohol again, or how you’ll get more of the substance you’re abusing.
Dependence Without Addiction
However, you can still choose to not take the substance while dealing with these triggers — with addiction, it’s almost impossible to not take the substance when in these situations. Psychological dependence is when the use of substance ties to a feeling or event, called triggers. It’s not quite the same as physiological dependence, because it requires a trigger for you to crave that substance. Your brain and body don’t like not having caffeine in them, so they turn up the pain. Does not mean the patient has a substance use disorder — it just means they need medication to have a higher quality of life. Regular thoughts about drug abuse or alcohol abuse, like when, where, and how you’ll use them again. After habitual use develops, the body expects a certain frequency and pattern.
Withdrawal syndrome, also known as discontinuation syndrome, occurs in individuals who have developed physiological dependence on drugs or alcohol and who discontinue or reduce their use of it.

In an animal model demonstrating excessive alcohol consumption induced by such a postdependent state , pharmacological blockade of κ-opioid receptors led to a significant reduction in high alcohol intake . This suggests that κ-opioid receptors may also play a role in alcohol relapse and craving, although administration of the κ-opioid receptor antagonist nor-binaltorphimine (nor-BNI) did not reduce the ADE (Figs. 12–17) . Alcohol dependence is thought to represent a persistent dysfunctional (i.e., allostatic) state in which the organism is ill-equipped to exert appropriate behavioral control over alcohol drinking. Although currently few treatments are available for tackling this significant health problem and providing relief for those suffering from the disease, there is hope. The foundations for understanding the neurochemical substrates of alcohol reward were laid in 1973 by the three research teams responsible for identifying the first opioid receptors . Only two years later in the hunt for the endogenous ligands, John Hughes and Hans Kosterlitz identified the first opioids in the brain and called them enkephalins.
A. A Retrospective View of Neurobiological Alcohol Research
Knockout mouse models and pharmacological manipulations of various components of the 5-HT system have indicated a modulatory role for 5-HT in voluntary alcohol consumption. Deletion of 5-HT transporters or overexpression of 5-HT3 receptors leads to a reduction in alcohol self-administration compared with that observed in control mice. Pharmacological manipulations of 5-HT system activity revealed that administration of a variety of serotonergic compounds were capable of reducing alcohol consumption in common stock as well as alcohol-preferring animals . 5-HT3 receptor antagonists were shown to suppress the acquisition of voluntary alcohol consumption in alcohol-preferring P-rats. Furthermore, the reinforcing effects of ethanol within the posterior VTA of rats require activation of local 5-HT3 receptors ; a pattern therefore evolves linking the action of 5-HT3 receptors on DAergic neurons within the VTA with alcohol reinforcement.

When to Seek Treatment for Psychological Dependence
It exerts its effects by blocking the NMDA receptor channel, in a similar manner to the physiological channel blocker Mg2+. Neramexane displays strong voltage dependency and a rapid blocking/unblocking kinetic. These pharmacological features allow neramexane to block the sustained activation of synaptic glutamate and to exit the receptor rapidly during normal physiological activation by millimolar concentrations of glutamate . In particular, it has been observed to reduce alcohol consumption following alcohol deprivation , and a phase II study was recently initiated on the basis of these preclinical results. In this multicenter trial, neramexane was tested physiological dependence on alcohol against placebo in detoxified alcohol-dependent subjects for the rate of continuous abstinence, duration of abstinence, craving, and drinking patterns. However, no major differences were detected between the two treatment groups for any of the outcome measures (G. A. Wiesbeck, personal communication). Relatively high doses of the drug should be administered in the context of its use as a substitution therapy, although this option is limited due to the relatively small therapeutic window of NMDA antagonists in alcohol-dependent subjects. Alterations in NMDA receptor subunit composition in alcohol-dependent subjects may also contribute to a lack of effect.
Enhanced voluntary alcohol drinking in dependent mice produced brain alcohol concentrations similar to those achieved during the chronic alcohol exposure that initially rendered the animals dependent. Samples were collected from the nucleus accumbens of alcohol-dependent mice that had undergone three cycles of chronic intermittent alcohol vapor exposure and nondependent controls . Samples were taken before, during, and after the 2-hour drinking session, when the mice had the opportunity to voluntarily drink alcohol (15 percent vol/vol) or water. Alcohol intake during the drinking session was 3.04 ± 0.15 g/kg for dependent mice and 2.32 ± 0.28 g/kg for nondependent mice. Horizontal lines and shaded area represent brain alcohol levels (means ± SEM) measured in the dependent mice during chronic intermittent alcohol exposure (28.4 ± 3.5 mM). Schematic illustration of how problem drinking can lead to the development of dependence, repeated withdrawal experiences, and enhanced vulnerability to relapse.
The future therefore seems bright, and the pharmaceutical industry appears to have overcome its initial reluctance to become involved in this very lucrative market. However, such studies would need to be performed over a long time period, with repeated measurements being taken over several weeks or even months; data handling and analysis would be further limiting factors. 1The terms alcohol and ethanol are used interchangeably throughout this review. However, the term ethanol is mostly used in the context of a specific effect, e.g., a specific pharmacological effect. When you forfeit activities that were usually enjoyed before drug use, it is an implication of the social symptoms of an addict. These activities or events, that previously brought joy, are now looked sourly upon due to the substance not being available. Even less problematic discomforts, such as sweating and teary eyes, are both attributes of physical addictive dependence versus psychological addictive dependence. Substance use disorder involves psychological aspects and changes to the body’s processes. Your brain will respond differently to regular stimuli due to its altered state.

Psychological dependence is the change in an emotional state after using a substance or engaging in a behavior for a long period of time. After long-term substance use, the brain gets used to having these chemicals boost dopamine levels. Psychological addiction is a brain disorder that causes a person to use the substance despite negative outcomes. Physical dependence happens when a person’s body is dependent on a substance. When a person does not drink alcohol, they are faced with physical symptoms such as rapid heart rate, nausea, and shaking. Neurobiologically driven research clearly indicates that the development of a complex psychiatric disorder such as alcoholism is not caused by any single gene or simple molecular event. However, the reductionist research approach only permits testing of the involvement of a single gene or a simple molecular event in the etiology of alcoholism. This dilemma can only be solved by the application of a systems biology approach. This necessitates the breaking down of a system into different levels, as exemplified by the structure of this review.
Which of the following is a psychological risk factor for addiction?
Reviews of the psychosocial risk factors of adolescent alcohol and drug use suggest that the highest risks can be summarized as: 1) psychological functioning, 2) family environment, 3) peer relationships, and 4) stressful life events.
