What is Physiological Dependence?

The dependence-producing properties of alcohol have been studied extensively in the last 20 years. Alcohol affects a wide range of neurotransmitter systems in the brain, leading to the features of alcohol dependence. The main neurotransmitter systems affected by alcohol are gamma-aminobutyric acid (GABA), glutamate, dopamine and opioid (Nutt, 1999).

• People dependent on alcohol also tend to build a tolerance for it, which causes them to drink more to get the same effect of intoxication.
• Alcohol dependence is a previous (DSM-IV and ICD-10) psychiatric diagnosis in which an individual is physically or psychologically dependent upon alcohol (also chemically known as ethanol).
• Slurred speech, a key sign of intoxication, happens because alcohol reduces communication between your brain and body.
• The more you drink, the more your body gets used to processing alcohol and functioning with alcohol in your system, and the more alcohol you’ll have to consume to feel drunk.

The recently established National Alcohol Treatment Monitoring System (NATMS) reported 104,000 people entering 1,464 agencies in 2008–09, of whom 70,000 were new presentations (National Treatment Agency, 2009a). However, it is not possible to identify what proportion of services is being provided by primary care under the enhanced care provision as opposed to specialist alcohol agencies. Following ingestion, alcohol is rapidly absorbed by the gut and enters the bloodstream with a peak in blood alcohol concentration after 30 to 60 minutes.

6. PHARMACOLOGY OF ALCOHOL

For instance, those people who rely on strong opiate pain medication will develop tolerance over time and may experience withdrawal symptoms if they stop. It would not be fair to say that this person is an addict though because they are taking this substance in a controlled way for medical benefit. When people talk about addiction they usually mean those individuals who are taking substances because they want to feel good. The patient who is taking these substances to help manage their pain usually does not suffer from psychological withdrawals should they stop.

• Few medications are approved for treatment of AUD, and these have exhibited small and/or inconsistent effects in broad patient populations with diverse drinking patterns.
• If you’re worried about your drinking, get in touch with your local GP surgery, who will be able to help.
• Considering the potential for treatment failure with approved pharmacological options or the inability to use a medication due to comorbid health conditions, a number of medications have been studied in AUD.
• Withdrawing under the care of medical professionals is the very best, most effective way to detox from drugs or alcohol in a safe, secure manner where complications are less likely to occur.
• Founded in the US in the 1930s, AA is based on a ‘12-step’ programme, and the ‘12 traditions’ of AA.

Have an increased risk for ischemic stroke, subarachnoid hemorrhage, peripheral vascular atherosclerosis, and an abdominal aortic aneurysm rupture. No amount of drinking is 100 percent safe, 100 percent of the time, for every individual woman” (National Institute on Alcohol Abuse and Alcoholism [NIAAA] 2003). Methamphetamine use has an array of possible adverse effects (for review, see Winslow et al. 2007), but data regarding specific gender differences are limited. Psychoactive effects of methylenedioxy- methamphetamine (ecstasy) have been found to be more intense in women than in men; women report experiencing a higher degree of perceptual changes, thought disturbances, and fear of the loss of control of their bodies. Acute adverse effects, such as jaw clenching, dry mouth, and lack or loss of appetite, are more common among women (Liechti et al. 2001).

Alcohol’s Effects on the Liver, the Neuroendocrine System, and Bone

A recent Scottish national alcohol needs-assessment using the same methods as ANARP found treatment access to be higher than in England, with one in 12 accessing treatment per annum. This level of access may have improved in England since 2004 based on the NATMS data. However, the National Audit Office (2008) reported that the spending on specialist alcohol services by Primary Care Trusts was not based on a clear understanding of the level of need in different parts of England. There is therefore some further progress needed to make alcohol treatment accessible throughout England. The primary role of specialist treatment is to assist the individual to reduce or stop drinking alcohol in a safe manner (National Treatment Agency for Substance Misuse, 2006). At the initial stages of engagement with specialist services, service users may be ambivalent about changing their drinking behaviour or dealing with their problems.

• This desire to use again can be so intense that it completely takes over the person’s thinking.
• Working with an addiction specialist can help you determine the proper course of action toward recovery.
• Opting for sobriety extends benefits to the cardiovascular (heart and blood vessels) system.
• Alcohol detoxification, recommended for alcohol dependent individuals, is the abrupt cessation of alcohol intake coupled with substitution of cross-tolerant drugs.
• 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).
• Alcohol affects a wide range of neurotransmitter systems in the brain, leading to the features of alcohol dependence.

In addition to chronic health diseases and conditions, persons in the end stage of alcohol abuse may be at a heightened risk of falls and other accidents due to balance and coordination problems. Most often, when death occurs after a fall, it is due to bleeding in the brain and not the fall itself. In essence, long-term treatment for individuals who have “psychological addictions” or “psychological dependence” compared to individuals who have developed “physical addiction” or “physical dependence” should not differ significantly in terms of the overall plan of recovery. High rates of depression and anxiety have been reported in adolescents with alcohol-use disorders, with increased rates of suicidality. Among clinical populations for alcohol-use disorders there was an increased rate of anxiety symptoms and disorder, PTSD and social phobias (Clark et al., 1997a and 1997b). For young people the presentation may be different because dependence is not common, with binge drinking being the pattern seen more often, frequently alongside polydrug use.

Alcohol use disorder

It can potentially be fatal depending on your drinking habits, how long you’ve been drinking, and how frequently you drink. When you stop drinking, you might notice a range of physical, emotional, or mental health symptoms that ease as soon as you have a drink. The connection between alcohol consumption and your digestive physiological dependence on alcohol system might not seem immediately clear. Over time, drinking can also damage your frontal lobe, the part of the brain responsible for executive functions, like abstract reasoning, decision making, social behavior, and performance. The alcohol dependence syndrome was seen as a cluster of seven elements that concur.

• The word psychological can be defined as relating to, or arising from the mind or emotions.
• Are more likely to have premature decline in lung function, chronic obstructive pulmonary disease, and coronary heart disease.
• This is of particular concern because alcohol presents particularly serious consequences in young people due to a higher level of vulnerability to the adverse effects of alcohol.
• More recent studies have also indicated certain genetic, social, psychological, or environmental factors may also impact the body’s dependency on alcohol.

Behaviorally, adolescent rats show greater impairment than adults in acquisition of a spatial memory task after acute ethanol exposure (Markwiese et al. 1998) in support of greater LTP sensitivity to alcohol in adolescents. Behavioral and neurobiological mechanisms for the ontogenetic differences in alcohol tolerance and sensitivity are unclear, as is the relationship between differential sensitivity to ethanol and onset of alcohol abuse and alcoholism. When addiction is related to drugs or alcohol, the condition is also called a substance use disorder. It could include prescription drugs, over-the-counter products, street drugs, alcohol, even nicotine.
