Dopamine

disorder where the person in question doesn’t have enough dopamine, a chemical that allows communication between the brain and body movements. The disease eliminates dopamine-producing nerve cells within the brain which accounts for problems with sleeping, motivation, thinking and much more. Currently, treatments for the disease include a drug named Levodopa, discovered in the 1960’s, it is ingested as a tablet or capsule and converts into dopamine once inside the body. In more severe cases…

This is my presentation of the effects drugs can have on the brain. Drugs are chemicals that tap into the brains communication system and tamper with the way nerve cells normally send, receive, and process information, when someone puts these drugs into their body. Different drugs because of their chemical structures work differently, and there are two ways drugs work in the brain, imitating the brains natural chemical messengers, and overstimulating the reward circuit of the brain. When a drug…

also increases the amount of dopamine and noradrenaline, the excessive release of serotonin is the primary mechanism of action. It induces desirable effects that are physical or psychological. However, prolonged MDMA use can disrupt normal serotonergic pathways in the brain by provoking neurotoxicity. Though MDMA affects the action of monoamine transporters, MDMA has a higher affinity to bind to serotonin transporters…

extra-cellular dopamine levels. The increase, in turn, reduces the backfiring rate of neuronal cells and thus leading to a decline in non-task related activity. Therefore, an increase in dopamine reduces unwanted activity and leads to an increase in attention and reduces one’s distractibility (Agay, Yechiam, Carmel, & Levkovitz, 2010; Volkow et al., 2001). Consequently, the therapeutic doses of MP treat the primary symptom of ADHD, namely deficiency in attention, by increasing the dopamine…

The patient (pt) in room 584 is an 84-year-old Caucasian woman who was transferred to Lynchburg General hospital on December 12, 2016 from Stonewall hospital in Lexington in order to receive pulmonary care. Though she was admitted for unspecified dementia without behavioral disturbances, she was originally hospitalized at Stonewall since September 21, 2016 for atrial fibrillation with a low ventricular response rate, and dyspnea. She has co-morbidities of Parkinson’s disease and Lewy body…

Chronic depression, also referred to as dysthymia or chronic depression is a mood disorder. Chronic depression is defined any feelings of hopelessness and unhappiness that persists for more than two weeks, and it is different from psychotic depression. With psychotic depression, the illness is accompanied by some form of psychosis, such as delusions, detachment from reality, and hallucinations. In addition to emotional disturbances, chronic depression is also like to sensory disturbances, such…

Drug =Survival. When you cross a line into addiction, Drug =Drug. In addiction, something goes wrong with the part of the brain to know things that are harmful, that is the brain pleasure sense. Addiction is the ability of the brain to proceed, process and act upon pleasurable experience. The brain creates pleasurable experience, it brings reward and one can remember it. Addiction is pleasure unwoven. I feel the film narrator also gave a good explanation of the five theories of addiction- the…

With each drag and puff of smoke its cold steely hands grips the willing victim who will find it difficult to escape addiction’s powerful grasp. Of particular interest for the respiratory therapist is the addiction to nicotine. It is important for the healthcare worker to know how this addiction can occur, because tobacco use is associated with a variety of pulmonary diseases. One such disease is chronic obstructive pulmonary disease, or COPD. The prevalence of addiction to drugs, such as…

an individual, stimulating the nervous system to release dopamine, the neurotransmitter associated with reward and pleasure. A neurotransmitter is a chemical substance, it is released from the end of a nerve fibre due to the arrival of an emotional or physical impulse, in this case entertainment. The positive association of dopamine often triggers the urge to repeat a stimulating activity. As the stimulant is repeated the excess dopamine production then takes over the cingulate gyrus and the…

produce and regulate hormones. The brain is accountable for many functions of the human body and that is why it is important. A person that is diagnosed with Parkinson’s disease suffers from the lack of production and regulation of a hormone called dopamine. One may wonder how does this information correlate with…
