Acute and chronic alcohol and other drugs (AOD) can provoke, increase, or initiate psychiatric disorders. In some people, psychiatric disorders may not emerge until the abuse of substances. In the brain, there are overlapping areas that are both affected by drug use and mental illnesses. Studies have shown that brain changes stimulating from one may negatively affect another part of the brain or cause susceptibility to something else. In other cases, one part of the brain can be affected by both a psychiatric disorder and AOD. For example: dopamine is a known neurotransmitter that carries messages from one neuron to another. In alcohol/drug abuse, the release of dopamine is disrupted by limiting the brains natural chemical messengers or cause
A 38-year-old single woman, Gracie, was referred for treatment of depressed mood. She spoke of being stressed out due to conflicts at work, and took a bunch of unknown pills. She reported feeling a little depressed prior to this event following having ovarian surgery and other glandular medical problems. She appeared mildly anxious and agitated. She is frequently tearful, but says she does not have any significant sleep or appetite disturbance. She does, however, endorse occasional suicidal ideation, but no perceptual disturbances and her thoughts are logical and goal-directed.
How do the issues facing those doing strategic planning differ from those doing tactical planning? Can the two really be
Most alcoholics proceed to a stage where their brains or their bodies have been so harmed by alcohol that the effects persist even when they are not drinking. This stage may be reached...
The National Institute on Alcohol Abuse and Alcoholism writes this article to inform the world that alcohol is a brain disease that affects the body and mind. The article states that alcoholism is a type of addiction, which therefore means it is a complex disease. It affects the health and well-being of the person. Alcoholism was defined as a disease by the American Medical Association in 1956. David Rosenbloom, PhD, states, “They can’t stop because their brain has been changed.” Neurotransmitters in the brain such as, dopamine, serotonin, GABA, and glutamate, are disrupted by abused substances such as alcohol. This article will be helpful to me because it has specific examples and situation that explains that alcoholism is a disease.
Drugs are substances that disturb this delicate balance, because they have “passkeys” that let them open certain “locks” located between the neurons. The brain automatically adjusts to these substances from outside the body by producing fewer of its own natural “keys”. Cocaine is type of drug that affects the dopamine is a neurotransmitter which is connected with emotions and noradrenalin is connected with alertness. Cocaine is considered as an illegal drug in most countries but some considered it as an legal drug. Although cocaine is an illegal drug earlier ancient people used to coonsider it as a medicine to treat many illness. Cocaine is absorbed in the dopamine and the...
Genetics predispose an individual to having an increased chance of becoming codependent upon drugs or alcohol. Studies of twins and of families that are prone to addiction suggest that about 50% of the risk for drug addiction is genetically based (EBSCOhost). One well-characterized relationship between genes and alcoholism is the result of variation in the liver enzymes that metabolize alcohol (NIH). The result of the liver breaking down the alcohol faster is a higher tolerance. Individuals with a higher tolerance to alcohol, need to drink more than the average person in order to seek the same biological effect. When heavy drinkers suddenly stop or significantly reduce their alcohol consumption, the neurotransmitters prev...
This paper introduces a 35-year-old female who is exhibiting signs of sadness, lack of interest in daily activities and suicidal tendencies. She has no interest in hobbies, which have been very important to her in the past. Her lack of ambition and her suicidal tendencies are causing great concern for her family members. She is also exhibiting signs of hypersomnia, which will put her in dangerous situations if left untreated. The family has great concern about her leaving the hospital at this time, fearing that she may be a danger to herself. A treatment plan and ethical considerations will be discussed.
In Canada, 1 in 7 people suffer from poverty, this is translated to about 4.8 million people (Just the Facts, 2015). When living in poverty, people are faced with hardships that make it challenging for them to live a proper, healthy life. Living in poverty does correlate with the fact that these families will suffer from a low income. Families that have a low income are more likely to suffer from poor physical and mental health because they are unable to support themselves when it comes to nutrition and cleanly living conditions. Fresh, nutritious, organic foods typically cost much more than freezer and fast foods, charities that help these families do not provide enough fresh foods to maintain a healthy diet, unsanitary living conditions

The most commonly abused substances are Nicotine, Inhalants, Alcohol, Cocaine, Amphetamines, Prescription medications, Heroin, Ecstasy and Marijuana. 1a(National Institute on Drug Abuse, 2011) Initially, a person may find themselves using substances voluntarily and with confidence that they will be able to dictate their personal use. However, over the period of time that drug use is repeated, changes are taking place throughout the brain, whether it is functionally or structurally. Drugs contain chemicals that enter the communication system of the brain and disturb the way in which nerve cells would typically send, receive, and process information. The chemicals within these drugs will cause a disruption to the communication system by either imitating the brain’s natural chemical messengers or by over-stimulating the brains “reward system” by sending mass amounts of dopamine. As an individual prolongs his or her use of these substances, they may develop an addiction.
Drugs affect your brain and in turn can alter your moods and behavior. Drugs are chemicals that tap into our brain’s communication system and disrupt the way nerve cells receive, send and process information. Drugs interfere with the exchange of information in the brain producing changes that promote repeated drug use. Drugs can imitate the brain’s natural chemical messengers, or they over stimulate the reward circuit of our brain.
The author explains the fact that neurons have “one of two types of dopamine receptors, D1 or D2.” As said in the article D1 neurons send the brain the signal to keep going which in this case is to keep drinking alcohol. D2 neurons send the opposite signal when triggered. Research states that D1 neurons are what causes addiction and when more amounts of alcohol are being drunk that people are more exposed to alcoholism. Scientists hope to use this research to find more effective solutions to treat different addictions. In summary, scientists have discovered what is inside the brain that causes addiction to solve a problem that many people face
“Alcohol as well as many illicit drugs are depressogens, the repeated use of which, produces both the subjective feeling of depression and the neurovegetative signs such as sleep and appetite disturbance, cognitive ...
Neurotransmitters are chemicals that help transmit signals from one nerve in the brain to another (Drinkaware). Drinking decreases our mental sharpness and judgment. According to the National Institute of Alcohol Abuse and Alcoholism, “1,825 college students between the ages of 18 and 24 die from alcohol-related unintentional injuries, including motor-vehicle crashes” (NIAAA,). Another problem that affects us mentally is addiction. Alcohol is very addictive and people go through withdrawal. (Brittanica, Mark Keller). Alcohol affects human’s bodies and causes them to die at a young age. Alcohol harms your organs such as the heart, liver, pancreas, and the brain. (NIAAA). Also, there is an increase of developing cancer around the mouth, esophagus, throat, liver, and breast (NIAA). Consuming alcohol came lead to people taking actions they might not have taken when sober. Regular drinking lowers the levels of serotonin in your brain. This leads to depression and
According to the “National Survey on Drug Use and Health (NSDUH), drugs interact with the brain and body to alter moods, emotions, and behaviors by changing brain chemistry and a person’s perceptions, and by impacting how individuals interact with the world around them.”
