Physical Signs and Other Symptoms of Alcoholism & Alcohol Abuse

This leads to a cycle of addiction and dependence that contributes to substance use disorder. This article explores the symptoms, causes, stages, and treatment of substance dependence, also known as substance use disorder. 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. 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.

Problem Solving and Cognitive Control Processes: Then and Now

If your pattern of drinking results in repeated significant distress and problems functioning in your daily life, you likely have alcohol use disorder. However, even a mild disorder can escalate and lead to serious problems, so early treatment is important. Most human and animal research on alcohol and endocrine development has been conducted in females, but the limited data on both genders suggest that alcohol can have substantial effects on neuroendocrine function (see Dees et al. 2001; Emanuele et al. 1998; Emanuele et al. 2002a,b). Human studies have found that alcohol ingestion can lower estrogen levels in adolescent girls (Block et al. 1993) and lower both LH and testosterone levels in midpubertal boys (Diamond et al. 1986; Frias et al. 2000a).

Such disruption of information sharing between the hemispheres in alcoholics was predicted by experiments predating quantitative brain-imaging methods that provided behavioral evidence for callosal dysfunction long before it was demonstrated with behavior-neuroimaging studies (Oscar-Berman 1992). Similarly, another brain region that had been implicated in visuospatial processing deficits in alcoholics was the parietal lobes, assumed from studies of focal lesions; however, only recently was this association confirmed with MRI and visuospatial testing in alcoholics (Fein et al. 2009). However, the study did find that people who engaged in binge drinking more often were also more likely to be alcohol dependent. Regular drinking physiological dependence on alcohol can also affect overall mental health and well-being, in part because alcohol may worsen symptoms of certain mental health conditions, including anxiety, depression, and bipolar disorder. Neuroimaging studies have frequently implicated the orbitofrontal cortex and anterior cingulate gyrus in the later stages of addiction, showing activation of these brain regions during intoxication, craving, and bingeing, and their inactivation during withdrawal [32]. As these regions are involved in higher-order functions such as modulation of salience value of reinforcers and control/inhibition of prepotent responses, alterations to the functioning of these regions are likely to increase susceptibility to developing an addiction.

Substance Dependence Treatment

• Alcohol has been shown to enhance DAergic neuronal firing rate via decreased firing frequency of GABAergic units within the VTA and NA, thereby reinforcing the effects of alcohol within the pathways involved in reward [147].
• This article discusses alcohol dependence, alcohol abuse, and the key differences between them.
• Only 30% provide some form of assisted alcohol-withdrawal programme, and less than 20% provide medications for relapse prevention.

Moreover, researchers can use nutritionally complete, alcohol-containing liquid diets to induce alcohol dependence (Frye et al. 1981). Again, symptoms of dependence are augmented when animals repeatedly are withdrawn from the alcohol diet (Overstreet et al. 2002). In general, studies using these approaches have demonstrated that the pattern of alcohol exposure (i.e., the frequency of withdrawals) appears to be as important as the cumulative alcohol dose in revealing alcohol’s negative reinforcing properties. The positive reinforcing effects of alcohol generally are accepted as important motivating factors in alcohol-drinking behavior in the early stages of alcohol use and abuse.

• Alcohol intoxication can disrupt this fine balance, disturbing the brain’s natural equilibrium, and long-term, chronic use forces a person’s brain to adapt in an effort to compensate for the effects of alcohol.
• 3Shrinkage of the mammillary bodies is observed only after chronic alcohol consumption, whereas swelling can be observed with acute consumption (Sheedy et al. 1999).
• An alternative to operant procedures, free-choice responding allows researchers to examine alcohol consumption and preference in rats in their home-cage environment.
• The physical harm related to alcohol is a consequence of its toxic and dependence-producing properties.

Risk factors for alcohol use disorder

It is important, therefore, that health and social care professionals are able to identify and appropriately refer harmful drinkers who do not respond to brief interventions, and those who are alcohol dependent, to appropriate specialist services. Addiction psychiatrists also have an important role in liaison with general psychiatrists in the optimal management of people with alcohol and mental health comorbidity (Boland et al., 2008). Environmental, genetic, metabolic, and behavioral factors that influence restitution of neurofunction have yet to be identified but are amenable to study with neuroimaging. For most people who are alcohol dependent the most appropriate goal in terms of alcohol consumption should be to aim for complete abstinence. With an increasing level of alcohol dependence a return to moderate or ‘controlled’ drinking becomes increasingly difficult (Edwards & Gross, 1976; Schuckit, 2009).
