It is of note that adolescents with alcohol abuse disorders showed substantially greater brain activation in the prefrontal cortex and anterior limbic regions in response to images of alcoholic beverages than was the case with control adolescents. Furthermore, the degree of brain response to these images was highest in those adolescents with the highest monthly alcohol consumption and who reported a greater desire to drink . In conclusion, a link exists between the urge to drink alcohol and fMRI responses in areas of the brain involved in mediating alcohol reinforcement, desire, and episodic recall. Use of visual alcohol stimuli demonstrates that a similar link evolves in adolescents Sober Home with relatively brief drinking histories, suggesting a neural basis for the observed response to alcohol advertisements in adolescents with drinking problems. However, it is something of a puzzle why well-characterized alcohol-responsive genes (e.g., genes that encode neurotransmitter components) frequently do not arise in microarray analyses. One shortcoming of this kind of analysis is that transcript abundance for neurotransmission-related transcripts tends to be low compared with other gene categories. Thus minor changes in gene expression in the range of 20–30% usually cannot be reliably detected. However, a large number of genes affected by alcohol might fall in this range.
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.

Separating the body and mind when treating drug dependence would be counterproductive. The addiction impacts the whole person, so the person needs healing in all aspects. Psychological dependence traditionally refers to the behavioral decisions, emotional triggers, and other feelings and mental health factors which fuel addiction or result from it. Depression, anxiety, or risk-taking behaviors might be part of this category. The body and brain are now dependent on the substance and may not function well without it. Certain substances may even cause life-threatening symptoms if the drug is suddenly stopped. The best approach typically involves working with a professional to either gradually taper off use or stop use altogether while under supervision to manage withdrawal symptoms. When people use the term psychological addiction, they’re often talking about psychological dependence, not addiction.

Although the VTA-NAC pathway is the most extensively studied circuit with regards to reinforcement processes, it is clear that other brain regions, especially those of the extended amygdala, are also essential components . There is evidence that synaptic plasticity in two additional regions, the bed nucleus of the stria terminalis and the amygdala, may also be modified by ethanol. The BNST is considered to be a component of the extended amygdala and plays a role in stress- and reinforcement-related limbic circuitry. NMDAR-dependent LTP triggering in the BNST is impaired by acute ethanol ingestion, in part through the attenuation of NMDAR-mediated synaptic currents .

Talking to a professional or even a friend is another way to help combat withdrawals. In alcohol dependence, reduction of alcohol, as defined within DSM-IV, can be attained by learning to control the use of alcohol. That is, a client can be offered a social learning approach that helps them to ‘cope’ with external pressures by re-learning their pattern of drinking alcohol. In alcoholism, patients are generally not presumed to be ‘in remission’ unless they are abstinent from alcohol. It’s the response to substances like drugs or alcohol altering their brain chemistry. For some, addiction can happen without them becoming dependent upon a substance. Treatment professionals refer to this type of dependency as a process addiction, which includes non-drug triggers such as gambling, gaming, sex, etc. Substance abuse and mental health treatment helps you learn the reasons behind your addiction so that you can begin to heal from those challenges.
Drugs Associated with Physical and Psychological Dependence
Activation of the HPA axis and CRF-related brain stress circuitry resulting from alcohol dependence likely contributes to amplified motivation to drink. Similarly, systemic administration of antagonists that selectively act at the CRF1 receptor also reduced upregulated drinking in dependent mice (Chu et al. 2007) and rats (Funk et al. 2007; Gehlert et al. 2007). This latter finding suggests that elevated alcohol self-administration does not merely result from long-term alcohol exposure per se, but rather that repeated withdrawal experiences underlie enhanced physiological dependence on alcohol motivation for alcohol seeking/consumption. This effect apparently was specific to alcohol because repeated chronic alcohol exposure and withdrawal experience did not produce alterations in the animals’ consumption of a sugar solution . People with substance use disorders experience both physical and psychological dependencies. During physical dependence, your body becomes dependent on a substance to function. For instance, an opioid addiction may begin as a pursuit to get pleasurable feelings that come with the flood of dopamine initiated by the drug.

Psychological dependence just refers to the way that some people come to emotionally or mentally rely on a substance. Symptoms might also fluctuate, improving for a period of time and intensifying when you’re under a lot of stress. For example, some people have a dependence on their blood pressure medication.
