Dopamine

movements. It is believed that it is jump-started by a loss of neurons in the substanita nigra, a midbrain region. The cells are killed in the course of the disease and are linked to movement control. They produced a neurotransmitter, which is dopamine. Dopamine is required to be able to communication with other neurotransmitters and with cells in different brain areas. Genes can be determined to be active or dormant at a particular time because some proteins act as transcription factors, and…

bodies(55). Arvid carlsson revealed that dopamine, a neurotransmitter in neurons of substantia nigra. L – dopa drug is used to treat the deficiency of dopamine in the substantia nigra. 70% of the dopamine containing neurons will be lost causing dopamine deficiency and turns the tissue black. Major regions of brain are affected, lower region of the brain stem known as medulla oblongata, which moves up through the basal ganglia into cortical areas (56). Dopamine metabolites increase the reactive…

When diagnosing the patient, it is important to take all signs into account and differentiate between conditions with similar symptoms, especially in patients whose symptomology matches a plethora of illnesses. Differential diagnosis is used to distinguish between two or more medical conditions that have similar symptoms. Differential diagnosis aids in increased diagnostic accuracy of the diagnosis so that patients can be effectively treated. Differential diagnosis is used often, especially in…

and environmental factors that affect Parkinson’s disease. Such as, advancing in age, family heritage, being male gender, or exposure to toxins. Ultimately, the resulting of Parkinson’s disease is also due to the deprivation of a chemical called dopamine. As Parkinson’s starts and evolves over time, the nerve (neurons)…

An addict just injected himself with the potent drug of heroin. Dopamine, a neurotransmitter is then released. This is the "feel good feeling" receptor in your brain. Addictive drugs can release two to ten times the amount of dopamine that natural rewards do. In a person who becomes addicted, brain receptors become overwhelmed. The brain responds by producing less dopamine causing less impact on the brain's reward center. In time, the desired substance no longer gives them as much pleasure.…

Creativity is one of those weird outliers of psychology that never seems to have a determinable definition or perfect definition that everyone can agree. Most psychologists agree that for something to be called creative requires that the idea or product is original and functional. Creativity is thought of, by Freudian ideologies, as a part of the mental functioning operative in the id (Arieti, 1976). In other words, the individual uses it to seek pleasure and avoid pain. The word itself is as…

postural instability making the human unbalanced and uncoordinated. It stiffs up the limbs making the body very rigid and slow in movements. The disease comes with the loss of brain cells that eventually will release the chemical called dopamine. The role of dopamine of the human brain is very essential because it explains and controls our movements, emotions and response to various different pain and pleasure. It is a chemical messenger that works as a transmitter of the brain. Dopamine’s role…

1. The three treatment options function synergistically to benefit the patient with prostate cancer. The ionizing radiation causes single and double stranded breaks to the neoplastic cells DNA, this halts replication and cell function until it can be repaired. Etoposide is a podophyllotoxin that inhibits topoisomerase II, the enzyme responsible for unwinding the DNA. If the DNA cannot unwind, the cell will be unable to replicate, transcribe mRNA, or repair itself. If the cell is unable to repair…

progressive neurological disease that occurs predominantly in later life. Parkinson’s disease occurs when the neurons in the brain begin to die; therefore, they cannot communicate with other neurons. The movement disorder is linked to a deficiency in dopamine production and is marked especially by tremor of resting muscles, rigidity, slowness of movement, impaired balance, and a shuffling gait. People may refer to Parkinson’s Disease as Parkinson’s, Parkinson’s Syndrome, Paralysis agitates, or…

Schizophrenia is one of the most complex and severe mental health disorders. Globally 1 percent of the population is diagnosed with schizophrenia, and roughly 1.2 percent of Americans have the disorder (Nemade & Dombeck, 2009). Schizophrenia is a lifelong progressive brain disorder, which is characterized by periods of psychosis. Currently, schizophrenia can be treated but not cured. No single factor is thought to cause schizophrenia; rather multiple factors contribute to the development of this…
