Change in View: Schizophrenia Moves From Psychology to Biology


Early on in the research regarding the disease schizophrenia, it was thought by doctors to be an illness of a psychological nature, not one relating to the brain. However, in the context of "Neurobiology and Behavior," and in recent light of new information about the disease, I will be examining it as a product of the brain, one that most now believe originates in early childhood. Not only that, but the evidence for it being a biological function of the brain also lies in genetics, with some startling statistics on the signs of the disease.

What is Schizophrenia?
In order to understand the entire paper, it is extremely necessary to cover the basic facts as to what schizophrenia is in patients. Schizophrenia, now seen as an illness of the brain, has been around as early as recorded history. For the longest time, however, people were seen as crazy and either tried as witches or condemned by society as lunatics. It was not until the rise of psychology that the disease was seen as a mental illness. Today, even more importantly, is the understanding that schizophrenia is a fairly common disease and drug treatments have been developed to help patients with symptoms. Approximately 1-1.5% of the population are diagnosed with it sometime throughout there lives, but I will get to general ages and percentages later on in general information. The disease itself has several key characteristics for diagnosis. Here is a short list of some of the symptoms:

1. Grossly abnormal behavior in terms of thought

2. Delusions

3. Hallucinations

Essentially, to translate the above statements, 1: The thoughts of someone with schizophrenia are not clear or logical any long...

...vior is no longer something mystical in origin, but pinpointed to a specific genetic or fetal factor. Perhaps, then, a final point to ponder is that the question raised in this course of brain=behavior will show itself to be true as more discoveries, like the one of schizophrenia being biological in nature, are made.

The Psychology of Religion Essay - The Psychology of Religion is composed of a variety of different perspectives, which in certain cases proves difficult in determining both the clinical and pastoral implications of a theory. Modern-day psychology has demonstrated possible beneficial results in religious spiritual individuals, however, much of the current research has avoided questioning the “real” presence of the Divine or a Higher Being. Although a century has passed since his undertaking of psychoanalysis, Sigmund Freud readily settled the question of religion by declaring it a form of mental illness....   [tags: Psychology ]

Essay on Is Psychology a Science? - The British Psychological Society states that ‘Psychology is the scientific study of people, the mind and behaviour’ (BPS). In this essay I will be discussing what is actually meant by this and whether psychology fits into both the traditional views of a science, as well as more contemporary perspectives. It is widely suggested that Psychology is a “coalition of specialities” meaning it is multi-disciplinary (Hewstone, Fincham and Foster 2005, page 4). I will therefore examine whether it could be considered wrong to think that all parts of the discipline should neatly fit into one view of a scientific approach....   [tags: Psychology ]

Psychology Theories Essay - I chose Gestalt Psychology for my first perspective, it is how people experience objects and perceive things as a whole. Gestalt allows us to look at everyday objects and distinguish them from their surroundings. Without the Gestalt Theory people would see every atom that made up a whole object. As I look at my computer screen, I do not see every little atom, I see the screen as a whole. From this perspective, learning objects as a whole instead of each individual part is beneficial because it allows us to open our minds for new learning experiences....   [tags: Psychology]

However, in 1879 Wilhelm Wundt opened the first psychology laboratory at the University of Leipzig in Germany.
