The third category of health-related costs is the loss to society because of premature deaths due to alcohol misuse. 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. It readily crosses the blood–brain barrier to enter the brain where it causes subjective or psychoactive and behavioural effects, and, following high levels of chronic alcohol intake, it can cause cognitive impairment and brain damage.

Alcohol Consumption in the U.S.

Key elements of the stress circuit are corticotropin-releasing factor (CRF) and norepinephrine (NE)-releasing neurons that converge on γ-aminobutyric acid (GABA) interneurons in the central nucleus of the amygdala and which are activated during the development of dependence. Although approved pharmacologic treatment options for patients with AUD are limited in number, recent trials describe a host of alternative approaches to reducing alcohol consumption. These include the use of antipsychotics, antidepressants, anticonvulsants, and others, under the rationale that these drugs target the neurotransmitter systems that have been shown to undergo changes with chronic exposure to alcohol. This review describes current evidence for the clinical use of a broader range of pharmacotherapies in AUD, along with available information on patient characteristics (eg, genetic, demographic, behavioral) that may predict positive outcomes of treatment. Addiction treatment trials often use the Diagnostic and Statistical Manual of Mental Disorders (Text Revision), 4th edition (DSM-IV-TR) definition of alcohol use disorders ([AUD] abuse or dependence) to define study participants.

What Increases the Risk for Alcohol Use Disorder?

There are several special populations which require separate consideration because they have particular needs that are often not well met by mainstream services, or require particular considerations in commissioning or delivering care, or who require modification of general treatment guidelines. Specific guidance applying to special populations will be referred to in the appropriate section in subsequent chapters. Alcohol dependence is also a category of mental disorder in DSM–IV (APA, 1994), although the criteria are slightly different from those used by ICD–10. For example a strong desire or compulsion to use substances is not included in DSM–IV, whereas more criteria relate to harmful consequences of use.

What Is Alcohol Dependence?

However, uncomplicated alcoholics normally do not endure discrete and complete structural brain lesions, per se. With the advent of computed tomography (CT), significant progress was made in indexing the severity of brain shrinkage in terms of enlargement of the ventricles and regional cortical sulci (see figure 2B and C). The expansion of the fluid-filled spaces of the brain was interpreted as a sign of local tissue shrinkage rather than as irreversible tissue loss (i.e., atrophy) (Ron et al. 1982). AUD is a serious health condition, and alcohol in general is considered one of the leading preventable causes of death in the United States [3], where 14.4 million adults (ages 18+) and over 400,000 adolescents (ages 12–17) have experienced AUD [4]. Globally, the harmful use of alcohol causes approximately 5.9% of all deaths annually, and 5.1% of the global burden of disease is attributable to alcohol consumption [5]. Additionally, chronic alcohol consumption has been shown to reduce total sleep time as well as quality [2].

In addition, 21% of adult men and 14% of women met the government’s criteria for binge drinking. Hazardous drinking among men varied from 24% in the West Midlands to 32% in Yorkshire and Humber, and in women from 15% in the East of England to 25% in the North East. Harmful drinking in men varied from 5% in the East Midlands to 11% in Yorkshire and Humber, and in women from 2% in the East of England to 7% in Yorkshire and Humber. Binge drinking among men varied from 19% in the West Midlands to 29% in Yorkshire and Humber and among women from 11% in East of England to 21% in Yorkshire and Humber (Robinson & Bulger, 2010). In more common language and in earlier disease-classification systems this has been referred to as ‘alcoholism’.

• Social learning theory also provides some explanations of increased risk of excessive drinking and the development of alcohol dependence.
• Approximately one third of specialist alcohol services exclusively provide treatment for people with alcohol problems, but the majority (58%) provide services for both drug and alcohol misuse.
• People who are seriously dependent on alcohol can also experience physical symptoms of alcohol withdrawal like shaking, sweating or nausea when their blood alcohol level drops – for example, before their first drink of the day.
• These changes can compromise brain function and drive the transition from controlled, occasional use to chronic misuse, which can be difficult to control.
• For people who are alcohol dependent, the next stage of treatment may require medically-assisted alcohol withdrawal, if necessary with medication to control the symptoms and complications of withdrawal.

Short-Term Effects of Alcohol on the Brain

Therefore it is impossible to define a level at which alcohol is universally without risk of harm. CBT is another form of structured one-on-one psychotherapy used to treat AUD, which focuses on increasing awareness physiological dependence on alcohol of the interplay between cognition, emotions, and behaviour [226]. The goal of CBT is to correct the maladaptive thought processes learned over time in order to change subsequent emotions and behaviours.

Physical Dependence On Alcohol

5One mechanism by which electrochemical signal transmission between neurons is terminated is by reuptake of the neurotransmitter into the signal-transmitting cell. When excess neurotransmitter remains in the synapse, receptors on the presynaptic terminal are activated to prevent the release of more neurotransmitter into the synapse. Another method for assessing the reinforcing properties of alcohol is intracranial self-stimulation (ICSS).

Although outside the scope of the present review, it is worth noting that other non-pharmacological approaches that may have therapeutic value in AUD include repetitive transcranial magnetic stimulation, transcranial direct current stimulation, and deep brain stimulation. For a more in-depth discussion of these therapeutic interventions, please see [245,246,247,248]. Over time, the damage done can lead to alcoholic neuropathy, where the peripheral nerves in your limbs have been badly damaged by alcohol.
