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…

Chapter 4: [Application] Parkinson’s disease 4.1 Introduction Parkinson's is a progressive neurological condition. - People with Parkinson's don't have enough of a chemical called dopamine because some nerve cells in their brain have died. - Without dopamine people can find that their movements become slower so it takes longer to do things. In the UK, one person in every 500 has Parkinson's. That's about 127,000 people in the UK. Most people who get Parkinson's are aged 50 or over but younger…

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…

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…

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…

through the increased release and decreased reuptake of the dopamine neurotransmitter within the synaptic gap, especially in the nucleus accumbens (Volkow, 1997). Over time, the repetitive influx of dopamine molecules can have detrimental effects on dependant individual, including depression (Hart, 2012). A study performed by Valklow and colleagues uses Positron Emission Tomography (PET) imaging to view the brain’s response to a dopamine influx in both participants that have been previously…

effect on the substantia nigra. This part of the brain is by the base of the brain. • Dopamine is created in this area. After the dopamine is created it goes to the next part of the brain termed corpus striatum which is creates movement that is steady and continuous. • Without dopamine it causes the movement function to deteriorate. • It takes a while for symptoms to appear. Over half of the cells that make dopamine are gone before any symptoms present themselves. • Parkinson’s disease has…

degeneration of the basal ganglia of the brain and a deficiency of the neurotransmitter dopamine. Causes: Nerve cells use a brain chemical called dopamine to help control muscle movement. With Parkinson’s disease, the brain cells located in the substantia nigra that make dopamine become impaired or die. Researchers do not know the cause of the death of the cells in the substantia nigra however. Without dopamine, the nerve cells that control movement is not able to send messages to the muscles.…
