Studies in England have tended to find over-representation of Indian-, Scottish- and Irish-born people and under-representation in those of African–Caribbean or Pakistani origin (Harrison & Luck, 1997). There are relatively few specific specialist alcohol services for people from ethnic minority groups, although some examples of good practice exist (Harrison & Luck, 1997). Amongst those who currently consume alcohol there is a wide spectrum of alcohol consumption, from the majority who are moderate drinkers through to a smaller number of people who regularly consume a litre of spirits per day or more and who will typically be severely alcohol dependent. However, it is important to note that most of the alcohol consumed by the population is drunk by a minority of heavy drinkers. Alcohol was consumed by 87% of the UK population in the past year (Fuller, 2009).

Current practice in treating AUD does not reflect the diversity of pharmacologic options that have potential to provide benefit, and guidance for clinicians is limited. 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. The need for continued research into the treatment of this disease is evident in order to provide patients with more specific and effective options.

If you’re concerned about someone who drinks too much, ask a professional experienced in alcohol treatment for advice on how to approach that person. Taken together, a substantial body of evidence suggests that changes in CRF function within the brain and neuroendocrine systems may influence motivation to resume alcohol self-administration either directly and/or by mediating withdrawal-related anxiety and stress/dysphoria responses. Alcohol dependence, which is also known as alcoholism or alcohol addiction, describes the most serious form of high-risk drinking, with a strong – often uncontrollable – desire to drink. The UK Cabinet Office recently estimated that the cost of alcohol to society was £25.1 billion per annum (Department of Health, 2007). A recent report by the Department of Health estimated an annual cost of £2.7 billion attributable to alcohol harm to the NHS in England (Department of Health, 2008a).

More recently, however, researchers have been turning their attention to the evaluation of changes in withdrawal symptoms that extend beyond physical signs of withdrawal—that is, to those symptoms that fall within the domain of psychological distress and dysphoria. This new focus is clinically relevant because these symptoms (e.g., anxiety, negative affect, https://ecosoberhouse.com/ and altered reward set point) may serve as potent instigators driving motivation to drink (Koob and Le Moal 2008). Sensitization resulting from repeated withdrawal cycles and leading to both more severe and more persistent symptoms therefore may constitute a significant motivational factor that underlies increased risk for relapse (Becker 1998, 1999).

Neurobiology and pathophysiology of AUD

The prevalence of alcohol-use disorders in this population has been reported to be between 38 and 50% in the UK (Gill et al., 1996; Harrison & Luck, 1997). In the US, studies of this population typically report prevalence rates of 20 to 45%, depending on sampling methods and definitions (Institute of Medicine, 1988). Alcohol is a toxic substance and its toxicity is related to the quantity and duration of alcohol consumption. In the brain, in a single drinking episode, increasing levels of alcohol lead initially to stimulation (experienced as pleasure), excitement and talkativeness. At increasing concentrations alcohol causes sedation leading to sensations of relaxation, then later to slurred speech, unsteadiness, loss of coordination, incontinence, coma and ultimately death through alcohol poisoning, due to the sedation of the vital brain functions on breathing and circulation. There is a wide range of other environmental factors that predispose to the development of alcohol-use disorders (Cook, 1994).

If you’re worried about your drinking, get in touch with your local GP surgery, who will be able to help. The society that you live in plays an important role in how likely you are to develop problems with alcohol. For example, how easily available alcohol is, how much it costs, and pressure from friends, family or colleagues to drink.

However, there are distinct differences between physical and psychological addiction.

If You Have an Addiction

Activated neurons release chemical signaling molecules (i.e., neurotransmitters) that bind to specific proteins (i.e., receptors) on other neurons. Depending on the neurotransmitter involved, this binding leads to the electrical excitation or inhibition of subsequent neurons in the circuit. (For more information on nerve signal transmission, neurotransmitters, and their receptors, see the article by Lovinger, pp. 196–214.) Alcohol interacts with several neurotransmitter systems in the brain’s reward and stress circuits. Following chronic exposure, these interactions result in changes in neuronal function that underlie the development of sensitization, tolerance, withdrawal, and dependence. Research using pharmacological, cellular, molecular, imaging, genetic, and proteomic techniques already has elucidated details of some of these alcohol effects, and some of these findings will be discussed in other articles in this and the companion issue of Alcohol Research & Health. As a foundation for this discussion, the following sections briefly introduce some of the neural circuits relevant to alcohol dependence, categorized by neurotransmitter systems; however, this discussion is by no means exhaustive.

• Data on alcohol-related attendances at accident and emergency departments are not routinely collected nationally in England.
• In terms of hazardous drinking, in 2008, 21% of adult men were drinking between 22 and 50 units per week, and 15% of adult women were drinking between 15 and 35 units; a further 7% of men and 5% of women were harmful drinkers, drinking above 50 and 35 units per week, respectively.

Further, it is important to note that due to age-related changes in metabolism, intercurrent ill health, changing life circumstances and interactions with medications, sensible drinking guidelines for younger adults may not be applicable to older people (Reid & Anderson, 1997). Equivalent levels of alcohol consumption will give rise to a higher blood alcohol concentration in older people compared with younger people (Reid & Anderson, 1997). The US National Institute of Alcohol Abuse and Alcoholism (NIAAA) has therefore recommended people over the age of 65 years should drink physiological dependence on alcohol no more than one drink (1.5 UK units) per day and no more than seven drinks (10.5 UK units) per week. A related issue is that standard alcohol screening tools such as the AUDIT may require a lower threshold to be applied in older people (O’Connell et al., 2003). Comorbid psychiatric disorders are considered to be ‘the rule, not the exception’ for young people with alcohol-use disorders (Perepletchikova et al., 2008). Data from the US National Comorbidity study demonstrated that the majority of lifetime disorders in their sample were comorbid disorders (Kessler et al., 1996).
