Brain Disorders: What´s Brain Chemistry?
What is Brain Chemistry?
Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain. Every person's brain chemistry is slightly different, and a number of things can play a role in the levels of various neurotransmitters in the brain, and how those chemicals affect the brain's function. It is believed that difference in brain chemistry may explain a variety of behavioral disorders and phenomena.

Neurotransmitters:
The synapse is the connection between nerve cells (neurons) in animals including humans. The synapse joins the axons in one neuron to the dendrites in another. The diagram shows how the synapse connects

The problem of substance addiction is so common in society, yet some people still have a slight unwillingness to call such addiction a “disease.” Substance addiction and abuse has been officially recognized as a disease for many years now, but the public as a whole can waver in their ability to fully comprehend how addiction can be classified in this manner. Only by understanding it in this way will society be able to properly deal with those addicted to drugs and …show more content…
Some scientists maintain that the most critical part of recovering from addiction is the re-balancing of the person’s brain chemistry. Treatment and recovery centers can help with this, by letting people get the drug out of their system.

In the Left diagram you can see how the mechanism of brain chemistry functions. The cell on the left is communicating to the cell on the right using neurotransmitters like dopamine and serotonin. When there is a lack of serotonin in the synapse we experience this by having depression. In alcoholics and addicts this brain chemical depletion is common place. The brain chemistry imbalance in alcoholics and addicts is one of permanent damage.

    Addicts live in a world full of self-hatred and shame, and a multitude of these individuals do not want anyone to know the truth about their pain. Our textbook states that “ninety-five percent of untreated alcoholics die of alcoholism an average of 26 years early even if their death certificate might read they died of heart disease, cancer, or something else to protect the family, but the real reason they died is due to addiction” (Perkinson, 2012, p. 2). An individual’s repeated drug use causes long-lasting changes in their brain which causes long-lasting changes in their brain which causes the addict to lose voluntary control. The individual’s addiction is their only way of feeling normal which makes them feel hopeless, powerless, helpless,…

    Over 20 million Americans above the age of 12 have an addiction, and 90% of those with an addiction began drinking, smoking, or using illicit drugs before the age of 18. Many of these addictions are products of peer pressure and students attempting to be the life of the party. In Cole Meyers “Addiction” he shows us how the continued use of drugs can give one a short term gains to increase his or her social status; however, in the long term, addiction strips the individual of his or her identity.…

    Although people have been using and abusing substances for as long as these substances have existed, the study of of addictions with the exception of alcoholism did not really emerge until the 1960's-1970's. Through out the last decade multiple changes to how addiction is viewed have occurred. Due to advances in the medical field and a better understanding of the chemistry of the brain addiction is now viewed as a disease instead of just a lack of morals. Because of the prevalence of wide spread usage of opiods, cocaine, and marijuana in the 60's and 70's more comprehensive research was deemed necessary to not only treat but effectively prevent drug addiction and alcoholism. It was also during this time frame that different classes of substances were created and we see a shift in how drug offenders were handled from the once harsher punishments to required treatment programs.…

    Substance abuse and dependency persist as a major health and social concern in America. Author Joseph A. Califano, a former secretary of Health, Education, and Welfare notes, “it is hard to find an American family or circle of friends that substance abuse has not touched directly (Califano, J. A., p. 1, 2008).” Califano further explains that although Americans are 4 percent of the world’s population, Americans consume 65 percent of the world’s illegal drugs. Furthermore, one in four Americans will have an alcohol or drug disorder at some point in his or her life. Most of these individuals have parents, children, siblings, friends, community and colleagues who will “undergo psychological and social harm" (Califano, J. A., p. 1, 2008.).” Authors…

    All human behaviour has a biological basis where a chemical imbalance can cause abnormalities. An example of this is how neural activity effects mood, behaviour and cognition. Disease can cause certain areas of the brain to cease to function correctly possibly leading to abnormalities in neurotransmitter production. In the case of Parkinson’s disease the ability to perform motor control behaviours is reduced. This reduction has been linked to the loss of dopaminergic neurones which in turn decreases the release of the chemical neurotransmitter dopamine. The reduction of dopamine at a synapse prevents the firing of an action potential in the post-synaptic neurone reducing the ability to perform behaviours associated with motor control. Chemical imbalances that prevent a neuron…

    Addiction is a disease that I will battle for the rest of my life. After being sexually assaulted at the age of twelve, I started to self-destruct. Lack of parental support, less than pristine living conditions, and an addictive personality paved an expressway to a life of addiction. I chose to hang with undesirable people, and was introduced to Marijuana, LSD, Ecstasy, PCP, Cocaine, Heroin and eventually what became the love of my life, the prescription painkiller Morphine. Never did I think that trying pot would have a domino effect. It led me to try harder and more addictive substances ultimately turning my life upside down. Often publicly misunderstood, addiction is a complex, physical, and mental disease.…
