...Sociopaths For my final paper I am going to talk about how Sociopaths Brain works, also the procedure of diagnosing someone as a sociopath. So whats your definition of a sociopath? Crazy? Can hide emotions well? These are the stereotypical ideas of what a sociopath is but can we really predict if someone is a sociopath by just talking to them? Well first off, the correct definition of a sociopath is a person with a personality manifesting itself in extreme antisocial, or not wanting the company of others, attitudes, behavior, and lack of conscience. They have different personalities, they are very charismatic to others and most importantly the do not feel remorse. All these characteristics that make up a Sociopath could easily be mistaken...

...Research Paper Diagnosis and Treatment of Alzheimer’s Disease: Current Challenges Prepared by Ms. Rawan Al-Juweed Introduction Alzheimer’s disease (AD), the most common form of dementia, is a degenerative disorder of the brain that leads to memory loss1. AD affects 5.3 million Americans and is the seventh leading cause of death in the United States. There are two main forms of the disease. Familial AD affects people younger than 65, accounting for nearly 500,000 AD cases in the United States alone1. The remainder of AD cases occur in adults aged 65 and older and is classified as sporadic AD. The prevalence of AD varies among many different factors, including age, co-morbidities, genetics, and education level. There is no way to definitively diagnose AD without performing an autopsy. There is no cure for AD, however promising research and development for early detection and treatment is underway. Abstract Alzheimer’s disease was discovered in 1906 by Alois Alzheimer, a German neurologist and psychiatrist2. The disease was initially observed in a 51-year-old woman named Auguste D. Her family brought her to Dr. Alzheimer in 1901 after noticing changes in her personality and behavior. The family reported problems with memory, difficulty speaking, and impaired comprehension. Dr. Alzheimer later described Auguste as having an aggressive form of dementia, manifesting in memory, language and behavioral deficits3. Dr. Alzheimer noted many abnormal symptoms, including difficulty...

...Brain imaging techniques Introduction to brain imaging techniques and other methods A number of techniques are available to investigate the question of how and where in the brain particular perceptual and cognitive processes occur. Tasks or tests can be devised that place varying levels of demand on the cognitive, sensory or motor capacities of the participant being tested. Performance of these tasks is then correlated with physiological measurements, and on the basis of these results, we may go on to ascribe functions to areas of the brain. Whilst there is a growing fascination with imaging techniques in the popular media (e.g. ‘This is your brain on politics’), it’s important to bear in mind that each technique has limitations that often don’t get picked up on by newspaper editors who themselves have little-to-no experience using them. The most often overlooked limitation is the issue of ‘reverse inference’ – just because cognition X (e.g. using one’s memory) is associated with brain activation Y (e.g. activation in the prefrontal cortex), that doesn’t mean that if a participant displays activation Y, they are necessary engaging in cognition X. Below we highlight some key neuropsychological and neuroscientific techniques, and a few of their limitations. There are also a number of great blogs that deal with issues relating to neuroscience, particularly in the popular press (e.g. Bad Science, The Neurocritic, [citation needed]). Testing brain damaged subjects (Neuropsychology) ...

...to control the functioning of every human system. In this activity, you will explore the case of Phineas Gage, a young man who, in the 1800’s, suffered a horrific brain injury and simply walked away. He recovered and went on to live many more years, but his friends and co-workers said he was never the same. Physical wounds healed, but internal damage changed the personality of the man they all knew. His case will introduce you to the way our brain works and to the way in which specific areas of the brain control different parts of our personality and our ability to function. You will also explore the history of mapping the function of the human brain, from early methods based purely on observation to current methods using high-tech scans and measurements. In Activity 2.1.2, you built a brain on your Maniken® and explored the primary functions of key brain regions. In this project, you will investigate the parts of the brain that control specific abilities, such as musical talent and sense of taste, and create a map of your findings on an elastic swim (bathing) cap. Just as a street map directs people around a city and provides a description of key sights, your brain map will display key structures as well as a visual...

...detect the tumor or cyst early in its development. In the United States, many of the current methods are too costly, too invasive, unavailable for widespread use, and lack high sensitivity and specificity. There is a strong need to find a more promising screening method that is inexpensive, noninvasive, available for widespread use, and maintains high sensitivity and specificity. The immediate objective of this research project was to evaluate the current screening methods and make a recommendation for a future screening strategy with strong potential to detect the cancer in its earliest stages while improving the sensitivity and maintaining high specificity. The first step in the investigation process was to identify a high-risk population for pancreatic cancer. Then, current screening methods were evaluated based on their ability to detect pancreatic cancer among the defined high-risk population and their cost, invasiveness, availability, sensitivity and specificity. After determining the Magnetic Resonance Imaging (MRI) as the best current screening method, further research indicated that plasma microRNA in combination with the biomarker CA 19-9 has potential to detect pancreatic...

...Anatomy of Violence Paper December 2013 The Anatomy of Violence is a non-fiction book, written by Adrian Raine, which investigates and presents facts to prove a neurocriminology hypothesis. Adrian Raine conducted experiments, researched and studied the biological roots of violence. He inaugurated neurocriminology, a newer field that incorporates neuroscience methods with the intention of examining the causes of violent criminal acts. Raine analyzes criminal minds. He pieces together research, data, and experiments of psychology, neurology, and criminology in order to inform the public of this new notion which sheds a new light on why people are or become violent criminals. This book was very interesting, well-explained, an easy read and the author incorporated many scientific examples to back up his theories. Adrian Raine takes us on a scientific expedition and exposes brain malfunction to be the cause of violent criminal acts. Raine’s theories are interesting and definitely bring forth many important questions however, while reading, I found some of his concepts are difficult to fully envision for logical reasons. A number of his concepts give an overreaching impression and are a bit too broad. While Raine brings up many valid points, I found myself asking important questions while reading Anatomy of Violence. Does this new research and belief give criminals a “Get out of jail free” card? While reading this book, I asked myself, Will this new theory allow...

...Always washing your hands? Or perhaps you are always counting things or checking things. Are these actions taking over your life or constantly occupying your mind? Perhaps you have obsessive compulsive disorder (OCD). It was once thought that OCD was rare; however, recently it has been found that 2-3% of people have OCD. People with OCD are usually diagnosed by between the ages of 20 and 30, and about 75% of those who will develop OCD will show symptoms by age 30.This leads to a couple questions that need to be answered: What is OCD? What causes it, and what is the most effective treatment? These questions will be answered throughout the paper. OCD is an anxiety disorder that is described as someone with obsessive thoughts and/or compulsive behavior. People with OCD are caught up in repetitive behavior and thoughts that they cannot stop. Obsession is defined as unwanted, recurrent, and disturbing thoughts that a person cannot stop. These thoughts are unable to be suppressed and can result in severe anxiety. Compulsions are the result of the obsession. These are repetitive, ritualized behaviors that are done to alleviate the anxiety caused by the obsession. The most common obsessions are fear of contamination, fear of causing harm to another, fear of making a mistake, fear of behaving in a socially unacceptable manner, need for symmetry or exactness, and excessive doubt. The most common compulsions are cleaning/washing, checking, arranging/organizing, collecting/hoarding, and...

...Respiratory Disease Paper Kelly Lindquist HCS/245 10/30/2014 University of Phoenix Respiratory Disease Paper There are several types of respiratory diseases that not only affect, but claim the lives of people in the United States each year; “COPD” Chronic obstructive pulmonary disease, Lung cancer, Emphysema, and Pneumonia to name a few. Since smoking ban laws were enforced in public places lung cancer and its cause has become a controversial issue; this is why I chose lung cancer as the primary topic of respiratory disease. In this paper I will discuss lung cancers primary, secondary, and tertiary state as well as what makes it classified as such. I will also address the impact of Lung cancer on society as it relates to the business of health care and the use of resources. Lung cancer is classified by primary, secondary, and tertiary state. First or primary is to review behavior in secondary prevention; second, is to stress the need for behavioral research in tertiary prevention to shorten the delay of cancer treatment and diagnosis. Secondary prevention occurs when the disease is identified in the earliest stages when effective treatment can be administered so that mortality rates can be reduced. Tertiary prevention directly affects morbidity once symptoms or awareness has occurred. (Smith & Anderson, 1985) The chance of early detection and its success depends on clinical screening strategies and the stage of the disease at the time it is diagnosed. Lung cancer...

...Huntington’s Disease Personal Reference: Down in the Neurology department sat four family members patiently waiting for what seems to be a never-ending check up. As the doctor’s office door peaked open my mother and aunt both walked out with despairing eyes. When I looked up the doctor was handing my mother a best-known neurologist information card. At that moment silence broke out amongst us, as we knew a whole new life experience was on our hands. At age 34 my Aunt Eve was diagnosed with Huntington’s disease. Background/Introduction: Huntington’s disease historical timeline indicates the first made known observation of the disease was by American physician George Huntington in 1872. Examining the symptoms and condition Dr. Huntington wrote a detailed account defining the hidden facts behind the disease. Yet it wasn’t until 1911 when Charles Davenport made major contributions in acknowledging and understanding the sings, symptoms and heritability of HD. The National Library of Medicine defines Huntington’s disease as a genetic degenerative disorder of neurons due to a defect in one part of the DNA. HD is recognized as a hereditary neurological disorder taking a devastating toll slowly diminishing an individual’s ability to speak, walk and reason. Because HD is a programmed genetic disorder its degeneration of nerve cells results in uncontrollable movements, emotional disturbance, and eventually memory loss. Signs: Early onset signs of HD typically trail...

...Psychological Assoc., 2012). The left hemisphere exerts greater control over speech and language abilities in almost all right-handed and the greater part of left-handed people. In contrast, the right hemisphere is more involved in nonverbal emotional expression and visual-spatial tasks. Furthermore, the right side of the body is controlled by the left-brain while the left side of the body is controlled by the right brain. A thick band of nerves called the corpus callosum is the connection between the two hemispheres (Hockenbury & Hockenbury, 2012). Methods such as functional brain imaging using PET scans, for instance, are beneficial for recording brain activity while a participant is performing a particular task. To gain insight of the brain’s function of each hemisphere, the following study was conducted. As a control, the participant was asked to tap a pencil on a fresh sheet of paper using the right hand, and...

...Carattere Scientifico Policlinico S. Matteo, University of Pavia, Pavia, Italy Enteropathy-associated T-cell lymphoma (EATL) is a complication of celiac disease (CD). This tumor derives from the neoplastic transformation of aberrant intraepithelial T lymphocytes emerging in celiac patients unresponsive to a gluten-free diet. Poor adherence to a gluten-free diet, HLA-DQ2 homozygosity, and late diagnosis of CD are recognized as risk factors for malignant evolution of CD. Recurrence of diarrhea, unexplained weight loss, abdominal pain, fever, and night sweating should alert physicians to this complication. The suspicion of EATL should lead to an extensive diagnostic workup in which magnetic resonance enteroclysis, positron emission tomography scan, and histologic identification of lesions represent the best options. Treatment includes high-dose chemotherapy preceded by surgical resection and followed by autologous stem cell transplantation, although biologic therapies seem to be promising. Strict adherence to a gluten-free diet remains the only way to prevent EATL. (Blood. 2012;119(11): 2458-2468) Introduction Celiac disease (CD) is a chronic gluten-sensitive enteropathy characterized by a high prevalence in the general population and an increased mortality.1,2 It is well known that the increased mortality is mainly the result of the complications of CD itself, represented by refractory CD (RCD) and enteropathy-associated T-cell lymphoma (EATL).2 RCD is a form of CD that does not...

...Schizophrenia is defined as: a group of psychoses characterized by confused and disconnected thoughts, emotions, and perceptions. (Gromly,526) Schizophrenia is a brain disorder, which is identified by specific concrete symptoms. Schizophrenia is not a split personality, or multi-personality. It has been proven that schizophrenia is not caused by childhood trauma, bad parenting, or poverty. Schizophrenia is not the result of any action or personal failure by the individual afflicted with this terrible mental disorder. Schizophrenia is marked by extreme thought disorder, and is usually treatable with medication. Given proper support, many people with schizophrenia can learn how to deal with their symptoms, and lead reasonably comfortable and productive lives. (Schizophrenia) Schizophrenia is a very common disorder, which affects 1 out of 100 people in the world. (Schizophrenia) Schizophrenia can affect people of any age. Schizophrenia usually strikes young people between the ages of 16 and 25. It can also appear later in adulthood however, onset is less common after age 30, and rare after age 40. Although rare, there is a childhood form of the illness, it can be found in children as young as the age of 5. Schizophrenia does not discriminate. The disease affects men and women with equal frequency, the only difference is the common age that the onslaught of schizophrenia begins. For men, the age of onset for schizophrenia is often between the ages of 16 to 20 years of age. For...

...Psychology Ashley B. McVey Cecil College Abstract Whether it is the study of biopsychology and other fields of psychology or neuroscience, all psychologists and scientists are trying to understand the functions of the brain. The body and mind connection and how it reacts to certain behaviors or illnesses. Most all psychological functioning can be reduced to underlying brain processes. This should serve as reason alone as to why biology plays an important part in the study of psychology. Psychological factors play a role in whether a person develops a mental illness and in how well they recover from a mental illness, yet biological and genetic risk factors, or predispositions, are fundamentals to understanding mental illnesses. In this paper, we will look at Parkinson’s disease as an example of how biology has brought us to a deeper understanding of the psychology of mental illness. Psychology is an academic and applied discipline that involves the scientific study of mental functions and behaviors. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the psychological and neurobiological processes that underlie certain functions and behaviors. For this reason, biology plays a very important role in the study of psychology. Psychology determines what people perceive to feel and behave, but underlying it all, ultimately determining the way we act, feel and behave, is biology. A biological perspective...
