Long-Term Effects of Drug and Alcohol Addiction

This type of criticism could also be applied to other psychiatric disorders, and that has indeed been the case historically 23, 24. Few, if any healthcare professionals continue to maintain that schizophrenia, rather than being a disease, is a normal response to societal conditions. Why, then, do people continue to question if addiction is a disease, but not whether schizophrenia, major depressive disorder or post-traumatic stress disorder are diseases?

Despite manufacturer claims, these are chemical compounds rather than “natural” or harmless products. These drugs can produce a “high” similar to marijuana and have become a popular but dangerous alternative. This treatment usually involves the use of benzodiazepines, though anticonvulsants may also sometimes be used.

How Science Has Revolutionized the Understanding of Drug Addiction

In general, the more risk factors a person has, the greater the chance that taking drugs will lead to drug use and addiction. Risk and protective factors may be either environmental or biological. Most drugs affect the brain’s “reward circuit,” causing euphoria as well as flooding it with the chemical messenger dopamine.

• The variability in confounding influences and the different neuropsychological measures taken across studies highlight the need for high-quality, long-term prospective cohort studies with standardized measures to better understand the lasting consequences of adolescent drinking.
• So, when in the midst of withdrawal, it’s common for many people to experience a wide variety of mental health changes and challenges.
• The self-help support group message is that addiction is an ongoing disorder with a danger of relapse.

Preventing substance use disorder

• However, adverse memory-related outcomes may improve after prolonged drinking abstinence.
• The brain regulates your body’s basic functions, enables you to interpret and respond to everything you experience, and shapes your behavior.
• Imaging studies also reveal that many substances of abuse are related to reduction in volume of specific areas of the cerebral cortex, reflecting a pruning of synapses to make the brain highly efficient in drug-seeking.
• These symptoms can, on rare occasions, occur in withdrawal following use of stimulant drugs or alcohol, usually when someone is experiencing a particularly intense form of withdrawal syndrome or when already predisposed to psychotic disorders like schizophrenia.
• It is usually set in motion by some environmental cue related to drug use.

Synthetic cathinones, more commonly known as “bath salts,” target the release of dopamine in a similar manner as the stimulant drugs described above. To a lesser extent, they also activate the serotonin neurotransmitter system, which can affect perception. Synthetic cannabinoids, sometimes referred to as “K2”, “Spice”, or “herbal incense,” somewhat mimic the effects of marijuana but are often much more powerful. Drugs such as MDMA (ecstasy) and lysergic acid diethylamide (LSD) also act on the serotonin neurotransmitter system to produce changes in perception.

• Examples include methylenedioxymethamphetamine, also called MDMA, ecstasy or molly, and gamma-hydroxybutyric acid, known as GHB.
• Studies that follow groups of adolescents over time to learn about the developing human brain should be conducted.
• This means that when a person begins using a particular drug consistently over a certain period of time, the body will naturally adapt to that substance’s effects by changing its internal chemistry.
• These are provided in outpatient facilities or inpatient residential recovery programs.
• You can start by discussing your substance use with your primary care provider.
• As with other diseases and disorders, the likelihood of developing an addiction differs from person to person, and no single factor determines whether a person will become addicted to drugs.

Subtypes in addiction and their neurobehavioral profiles across three functional domains

The hope is that mechanistic insights will help bring forward new treatments, by identifying candidate targets for them, by pointing to treatment-responsive biomarkers, or both 52. Developing innovative treatments is essential to address unmet treatment needs, in particular in stimulant and cannabis addiction, where no approved medications are currently available. Although the task to develop novel treatments is challenging, promising candidates await evaluation 53. A particular opportunity for imaging-based research is related to the complex and heterogeneous nature of addictive disorders.

This statement, while correct in pointing out broad heritability of behavioral traits, misses a fundamental point. The fact that normal anatomy shapes healthy organ function does not negate that an altered structure can contribute to pathophysiology of disease. Critics further state that a “genetic predisposition is not a recipe for compulsion”, but no neuroscientist or geneticist would claim that genetic risk is “a recipe for compulsion”. what is drug addiction However, as we will see below, in the case of addiction, it contributes to large, consistent probability shifts towards maladaptive behavior. But the disease model also wrongly suggests that the brain changes in addiction are permanent and that addiction is a chronic condition, that those who are addicted are unable to overcome it by themselves, and that relapse is an ever-present danger even to the recovered.

However, this criticism neglects the fact that neuroimaging is not used to diagnose many neurologic and psychiatric disorders, including epilepsy, ALS, migraine, Huntington’s disease, bipolar disorder, or schizophrenia. Even among conditions where signs of disease can be detected using brain imaging, such as Alzheimer’s and Parkinson’s disease, a scan is best used in conjunction with clinical acumen when making the diagnosis. Thus, the requirement that addiction be detectable with a brain scan in order to be classified as a disease does not recognize the role of neuroimaging in the clinic. In dismissing the relevance of genetic risk for addiction, Hall writes that “a large number of alleles are involved in the genetic susceptibility to addiction and individually these alleles might very weakly predict a risk of addiction”.

The effects of drug misuse on the brain and mental health

This is followed by a discussion of the main points raised when the notion of addiction as a brain disease has come under criticism. Key among those are claims that spontaneous remission rates are high; that a specific brain pathology is lacking; and that people suffering from addiction, rather than behaving “compulsively”, in fact show a preserved ability to make informed and advantageous choices. In the process of discussing these issues, we also address the common criticism that viewing addiction as a brain disease is a fully deterministic theory of addiction. For our argument, we use the term “addiction” as originally used by Leshner 1; in Box 1, we map out and discuss how this construct may relate to the current diagnostic categories, such as Substance Use Disorder (SUD) and its different levels of severity (Fig. 1). • the hippocampus, seat of memory; under the influence of dopamine, the memory of an expected reward results in overactivation of the reward and motivation circuits and decreased activity in the cognitive control centers of the prefrontal cortex.
