How Alcohol Affects the Central Nervous System Alcohol can affect several parts of the brain, but in general, alcohol contracts brain tissue and depresses the central nervous system. When alcohol reaches the brain, it interferes with communication between nerve cells, by interacting with the receptors on some cells. The alcohol suppresses excitatory nerve pathway activity and increases inhibitory nerve pathway activity. Among other actions, alcohol enhances the effects of the inhibitory neurotransmitter GABA. Enhancing an inhibitor has the effect of making a person sluggish.
In this report I’m going to be telling you about how neurotransmitters affect our lives and the people around us. I’m also going to be explaining what these things called neurotransmitters are, the different type of neurotransmitters we have and what they do. Also what would happen to our body if we have too many or too little amounts of neurotransmitters and how illegal and legal drugs affect the functioning of neurotransmitters? Neurotransmitters are a chemical substance which is released at the end of a nerve strand by the entrance of a nerve impulse and by spreading across the synapse. It effects the transfer of the impulse to another nerve strand, a muscle strand, or another structure.
During an attack, the blood vessels in the brain dilate and then draw together with stimulation of nerve endings near the affected blood vessels (Worden, 1998-2011). These changes to the blood vessels are probably what cause the pain. But migraine is still a condition that is poorly understood (Worden, 1998-2011). Causes Many times we don’t realize that certain things that we eat and do can affect our health. Sometimes the light and smells could have an effect on this disorder but the reasons why are still not known.
The use of methamphetamine is associated with long-term biochemical and structural effects on the brain and significantly changes how the brain functions. The excessive production of dopamine causes neuropathological changes in the brain and has a neurotoxic effect on the brain cells that store dopamine and serotonin. These changes include decreases in the levels of dopamine transporters as well as decreases in the density of serotonin transporters in various parts of the brain. Studies have demonstrated that daily use of methamphetamine results in increased cell death in the brain, which would have a negative effect on prefrontal cortex functioning. Changes in the activity of the dopamine system are associated with reduced motor skills and impaired verbal learning.
Some neuropathy pain might include damage to the nerves from high blood pressure, neuralgia and diabetic neuropathy. Viruses like shingles, phantom limb pain, and post stroke pain can cause this. Alcohol ken Block nerve pain because it interrupts the signal that is sent to the brain. It can be done by injecting the substance into or around a nerve located in the spine. Lidocaine is a topical anesthetic that
It affects the brain's pleasure systems and interferes with the brain's ability to perceive pain by depressing nerve transmission in the sensory pathways of the spinal cord and brain that signal pain. This explains why heroin is such an effective pain killer and why it has increasing physical addiction and ongoing emotional dependence. Heroin also inhibits brain centers controlling coughing, and breathing which makes it very dangerous. Heroin is exceedingly addictive, quickly producing tolerance and dependence. Although heroin is even more effective as a painkiller than morphine and codeine, it is so highly addictive that its use is illegal.
---------RESEARCH PAPER BY RAPHAEL, AGYAPONG-------------- ‘Addiction is a brain disease-and it matters’ (National Institute of Justice, US). Addictive behavior has been discussed and researched upon by many scientists as to its association or relationship with brain basis. This piece of findings seeks to provide evidence that addictive behavior has brain basis. To start with, any activity, substance, object, or behavior that has become the major focus of a person's life to the exclusion of other activities, or that has begun to harm the individual or others physically, mentally, or socially is considered an addictive behavior. (Altman et al.1996).
Effects of Drugs and Chemicals on the Brain and Body Ashley Schreij General Psychology 1030 – F01 Bob Zimmerman March 17, 2013 Effects of Drugs and Chemicals on the Brain and Body Drug abuse is something many people are familiar with. Different drugs affect each person and their mind and body differently. All drugs affect the mind and body differently but they all chemically alter the brain, some to an extent to where it has become an addiction. There are many drugs out there that are addicting and hazardous, but I am going to address some of the more known ones: 1. Alcohol 2.
Brain scans can be used to help diagnose some disorders. Furthermore, the genes we are born with, from our parents, provide the blueprint for our bodies and brains. A slight abnormality in our genes can affect the functioning of our brains. Also to operate properly the brain relies on hundreds of chemicals to operate in the correct balance, these chemicals are used to send messages around the brain. Therefore if there are chemical imbalances abnormality may occur, for example low levels of serotonin are linked to depression and schizophrenia is linked with high levels of dopamine.
Characteristics of Successful Programs Addiction is a complex but treatable disease that affects brain function and behavior. Drugs of abuse alter the brain’s structure and function, resulting in changes that persist long after drug use has ceased. This may explain why drug abusers are at risk for relapse even after long periods of abstinence and despite the potentially devastating consequences. No single treatment is appropriate for everyone. Treatment varies depending on the type of drug and the characteristics of the patients.
