Essays on Dopamine

ADHD is a behavioral disorder that exhibits a severe long-term effect on victims. The condition poses, even more, grave consequences on the health of females than males. Therefore, given that it can progress unnoticed during childhood, there is the need to conduct a thorough assessment to enable accurate diagnosis. Diagnosis is usually made using the Statistical Manual of Mental Disorders-Fourth Edition-Text Revision (DSM-IV-TR) criteria. An in-depth exploration of all the possible treatment recommendations begins after the diagnosis. In the treatment of DHD detected in the patient in the case study, various approaches can be considered. Usually, the treatment of ...

Parkinson’s disease lacks a cure but certain medicines can help manage the symptoms. These medications function to offer a substitute for dopamine, the signaling neurotransmitter in the brain. Carbidopa-levodopa is hitherto the most effective medicine to manage Parkinson’s disease. This chemical moves to the brain and is converted to dopamine. The chemical levodopa is mixed with carbidopa preventing it from being converted to dopamine prematurely out of the brain hence potential side effects such as nausea are lessened. Potential side effects with this medication however include orthostatic hypotension or feeling light headed and nausea. With continued use ...

Abstract

Rose hip (Rosa Canina), often cultivated for its fruits, are orange-red oval berries, which seeds (including shells) are used in supporting the treatment of bladder infection, diarrhea, diabetes, and related conditions often in the form of a 3-g powdered seeds capsule. Its seed oil contains ascorbic acid, carotenoids, polyphenols, and GOPO, which reduces inflammation and pain, and lowers inflammatory markers. Extraction methods used include solvent extraction, supercritical fluid extraction, and subcritical fluid extraction. Licensed rose hip supplement products include Hyben Vital and LitoZin/i-flex. Hyben Vital dosage is twice daily for 3 to 4 months to reduce osteoarthritic pain and ...

INTRODUCTION

There are so many different diseases, disorders, ailments and syndromes that can affect human beings in ways that can impact the quantity or quality of life of those who suffer from them. Biological Psychology is a specific discipline that focuses upon the behaviors of human beings and other animals based on the study of their physiology, genetics and mechanisms of development. One of the many different afflictions that Biological Psychologists are interested in is Tourette Syndrome, also called Tourette Disorder, Gilles de la Tourette Syndrome or simply TS or GTS; it was first discovered by Georges Albest Edouard Brutus ...

While the Etiology of the ADHD remains unclear, there are many theories, which should give an answer about the causes of disease. Current generally accepted theories believe that genetic factors and the environment in which the child grows play a key role in the development of the disease. The most attention is drawn to the differences of genes, which control dopamine neurotransmission in the brain of the ADHD patients. Dopamine plays an important role in cognitive activities. Activation of dopaminergic transmission is necessary for the processes of switching attention from one stage of human cognitive activity to another. According ...

The question of the validity of the use of stimulants for the treatment of attention-deficit hyperactivity disorder (ADHD) is highly connected to the question of attempting to balance the effectiveness of the drugs and the dangers inherent in their use. ADHD is a problematic mental and behavioral disorder especially among children and it is very important that we as a society find an effective method to treat it with the least amount of adverse effects to patients. It is a very good question to ask if a treatment is worth the risks and this definitely the case with the ...

Abstract

The Beck Depression Inventory (BDI) Test is used by the psychologists to determine the extent of depression among the patients so that adequate interventions and treatments can be incorporated to hinder the extent of depression. There are certain errors that can effect the test specially when respondents fail to understand the questions and are under influence of drugs or alcohol, due to which their responses do not remain valid to draw conclusions. The errors during the manual calculation of scores can lead to false interpretation whereas the prevalence of construct validity is also required to incorporate the consistent level ...

Drug abuse is a serious issue that plagues our society. Every age group has a fair share of drug users. However, according to the survey conducted by U.S Department of Health and Human Services, teenagers and young adults are two of the biggest culprits - 15.8% of people aged 16-17 and 22.6% of people aged 18-20 use drugs. The use of illicit substances by teenagers is caused by the fact that there’s no regulation of drugs like marijuana. A drug dealer isn’t going to check a person’s ID when he conducts a deal. Additionally, teenagers who ...

Abstract

Continuous exposure to a wide spectrum of natural light has constructive impacts to not only one’s health but also their moods. The production of hormones such as serotonin and melatonin based on the intensity of light has a large impact on the distribution of an individual’s emotions. This study seeks to validate the role of sunlight in the distribution of a person’s mood and whether a lack thereof has a negative impact on their emotional balance. The paper utilizes similar researches conducted on this issue to establish an argument about the constructive impacts of sunlight on ...

Although love is usually categorized as an emotion, a variety of biological, psychological, and sociological factors determine with whom a person falls in love and how long that feeling lasts. For example, physical attraction depends on factors such as physiological arousal, the effects of pheromones, facial features, and similarity, but biological factors do not contribute to the development of long-lasting relationships because the initial attraction fades (Braxton-Davis & Boudreaux, 2010, p. 7). In other words, it is possible to fall in love with a person because of biological factors, but psychological and sociological factors determine if the feeling persists and ...

Q1 People, especially children, internalize what they see in the environment and imitate it. In this regard, a child will behave the way adults do in the environment. Moreover, one can learn by the process of association (classical conditioning) or adopts behaviors depending on reinforcement. Q2 The emotional learning system focuses on one’s understanding of the immediate experiences. In this regard, one chooses how to behave based on critical and constructive thinking. Events that may lead to emotional responses may include reaction to stressful environments or happiness. Q3 Emotion determines one’s way of reacting to events. It ...

Introduction

Parkinson Disease (PD) is a very complicated neurodegenerative condition including the motor and non-motor manifestations that lead to neuronal loss. Currently, only symptomatic therapies are available but nothing is known yet to prevent this degenerative process. This is a multi-factorial condition with multiple risk factors that includes increasing age, genetic vulnerability, and environmental determinants. All these factors mutually play a role in the pathogenic process of PD. Medical sciences have achieved major advances in understanding the process working behind PD development that are Nigral Dopaminergic Apoptosis, Protein ...

A neuron is a specialized type of cell that helps in impulse conduction in the body. It is a basic unit of communication in the body. It receives and initiates the information reception and transmission to all parts of the body. The structure of the neuron is made of several parts that include dendrites, Soma (cell body), nucleus, cell membrane, axon, myelin sheath, a node of Ranvier and terminal Buttons or axon terminal (Marieb, 2004). The figure below shows the structure of the neuron. Figure 1: structure of neuron (Shonkoff & Phillips, 2010). For neural impulse to occur, the stimulus ...

Throughout the years, the world has advanced more through the usage of technology and the benefits it brings. In the beginning, there were only desktop computers that could do a limited amount of work, and now they have been transformed in portable tablets, laptops, and even phones. With this much portability on technology, it was certain that certain websites dedicated to keeping in touch with people were invented. The first successful social media website that was around during the early days of the internet was Myspace. Just like the social media websites today, a person could update their page ...

Cephalexin and Gentamicin The mechanism of action of amoxicillin is focused on the prevention of the synthesis of the bacteria’s cell wall through the binding and inhibiting of the cell wall transpeptidases (Katzung, Masters, and Trevor, 2012). Specifically, it attaches to the penicillin-binding protein 1A found in the cell wall of bacteria. Then, the agent disintegrates the lactam ring to allow the acylation of the penicillin-sensitive transpeptidase C-terminal domain. The formation of the cross-link of the linear peptidoglycan strands is prevented by the inactivation of transpeptidases. Since the third and last stage ...

Falling in love can be just as powerful as sniffing a line of cocaine. In fact, studies have shown that the effect cocaine has on the brain sometimes provokes similar chemical reactions as those caused by the feeling of being in love. However, despite love sometimes being classified as a natural stimulant, it could also be harmful to human health in certain situations. And given such similarities, the neural enhancement of both these stimulants should be taken both cautiously and seriously. In the scientific and common literature, love is almost always regarded as being a benefit to a person's ...

During the last century, scientists involved in research and studies on drug abuse were governed by the powerful misconceptions and fabricated stories about the addictive nature of the drugs and the reason behind drug addiction. Proper scientific studies on drug addiction started in the 1930s when the research was done to learn the behavioral aspects of addiction. People who were addicted to drug usage were considered as immoral individuals and those who lack willpower. During that time, these viewpoints shaped the response of the society towards drug abuse, considering it as an immoral act rather than treating it as ...

Summary

Over the past few years, there has been a growing interest among neurosurgeons on the potential for therapies that impact on diseases, over and above the movement disorders and pain. One of the biggest targets of this increasing interest has been the nucleus accumbens. It has been studied for long, as an area of the brain that mediates a variety of behaviors, including reward and satisfaction (Salgado & Kaplitt, 2015). With this in mind, the modulation of the biology of the Nucleus Accumbens through either deep brain stimulation or through biological therapies like gene therapy or the transplantation of cells ...

Brief summary

Cocaine use disorder (CUD) is considered to be a health problem because of the millions of people who are using it worldwide. The article states that excessive cocaine use will cause changes in the prefrontal Cortes (PFC) (Terraneo, p.37). The reason for this is because PFC plays a significant role in the addictive cycle such as the inhibitory control, reinforcement learning as well as cravings. Many types of research that have been conducted show that the loss of inhibitory control is brought on by drug behaviors. The article looks at the animal studies that have been carried out in ...

Summary: The interaction between the limbic system and the subcortical dopaminergic system, is important in the experience of reward by the individual. The hypothesis in the present study is that, increased excitability of the medial prefrontal cortex, exerts a suppressive effect on the interaction between subcortical dopaminergic system and the limbic striatum structures (Ferenczi et al.). Lack of a reward seeking behavior is seen in patients with depression and MRI studies in these subjects have identified increased excitability of the medial prefrontal cortex. This finding was suggested as a rationale for the study. The experiments were designed to demonstrate ...

Methamphetamine is the most devastating drug facing the society today, but only few people know about health problems which can be caused because of using it. Methamphetamine is a stimulant drug that was commonly used in 1960’s for medical purposes in order to cure depression or lose weight. It is a white, bitter-tasted crystalline powder that can be injected, swallowed or smoked. The constant use of methamphetamine can easily cause addiction characterized by constant drug seeking and abuse (National Institute of Drug Abuse, 2014). Being structurally similar to amphetamine, it has stronger effects on the central nervous system, ...

Psychodynamic psychology also called dynamic psychology is the chronological approach to the study of psychological forces and state of the mind in relation to human characteristics stressing the connection between unconscious and conscious procedures with effects to general mental functioning. Dynamic psychology is directed to the idea that humans life undertakings affects their unconscious and conscious ideologies and motivations which in turn correlate with the feelings, character, and general nature of behaviors. Freud the psychologist suggested that the conscious and unconscious parts of the brain come into conflict with each other, resulting to an observation known as repression. This ...

Drug abuse has become a worldwide issue, where each and every nation is struggling to control and prevent the ever increasing rate of drugs and substance abuse. As of today, the issue has become part of debate in almost all communities and nations in the world, and the question on who should take charge and how these issues should be solved without major effects on the society at large, has also raised more concern.

Drug and substance abuse refers to a maladaptive pattern of frequent use of a certain drug substance, which is not considered dependent (Abadinsky, 2010). While this definition may ...

The brain regulates the choice of a person to be physically active. Stimuli from the environment and from the tissues excite receptors and nerves which in turn excite the muscles. The central nervous system has three general areas that are associated with the complexity of the movement and the familiarity of the various stimuli. The areas include the spinal cord which handles simple reflex actions, the lower brain which organizes more complex responses while the cerebral cortex controls the most complicated responses and stores general motor programs. The spinal cord consists of two-way tracks of nerve fibers which carries both ...
