Jenna's doctor, Jacob, advises her to start taking antidepressant drugs that contain serotonin and dopamine. Impulses are transmitted between neurons (nerves) at synapses, junctions where neurotransmitters are released that inhibit or excite other neurons to achieve different responses. One option to treat severe mental illness is psychotropic medications. In this article we will discuss biological approaches to Depression. Biological factors include genetics, prenatal damage, infections, exposure to toxins, brain defects or injuries, and substance abuse. What are the 4 major types of medical biological therapies? A traumatic brain injury. This website uses cookies to improve your experience while you navigate through the website. Neuronal activity in the hippocampus of mice is associated with changes in DNA methylation (Guo et al., 2011), and disruption to genes encoding the DNA methylation machinery cause learning and memory impairments (Feng et al., 2010). The most common route of administration is oral administration, which is relatively slow and perhaps surprisingly often the most variable and complex route of administration. Virtually any drug that changes the way you feel does this by altering how neurons communicate with each other. You also have the option to opt-out of these cookies. This diathesis-stress model suggests that people with an underlying predisposition for a disorder (i.e., a diathesis) are more likely than others to develop a disorder when faced with adverse environmental or psychological events (i.e., stress), such as childhood maltreatment, negative life events, trauma, and so on. Psychopharmacology. Although they share exactly the same DNA, their unique experiences in life will cause some genes (and not others) to express themselves. According to the Genetics Home Reference website as part of NIHs National Library of Medicine, ageneis the basic physical and functional unit of heredity. Behaviorism addresses aspects such as classical conditioning, operant conditioning, and modeling. This cookie is set by GDPR Cookie Consent plugin. This new epigenetic research is pointing to a new strategy to understanding gene-environment interactions. Biomedical therapies include drug therapy, electroconvulsive therapy, and psychosurgery. There is not a unique enzyme for each drug; rather, certain enzymes can break down a wide variety of drugs. Sometimes individuals stop taking medication because the side effects can be so profound. 2.1 Biological Psychology - Introduction to Psychology - 1st Canadian A psychological disorder is an ongoing dysfunctional pattern of thought, emotion, and behaviour that causes significant distress, and that is considered deviant in that persons culture or society (Butcher, Mineka, & Hooley, 2007). Within each type of mammalian cell, about 2 meters of genomic DNA is divided into nuclear chromosomes. Knowledge from these studies may provide greater insight into other psychological disorders such as depression and suicidal behaviors. Early childhood is not only a period of physical growth; it is also a time of mental development related to changes in the anatomy, physiology, and chemistry of the nervous system that influence mental health throughout life. depression or schizophrenia while the cognitive approach would use Ellis's rational emotive therapy which would change the way someone thinks and how they perceive depression. It argues that behaviour is caused by hormones, neurotransmitters and genetics. It does not store any personal data. Key assumptions of the biological approach There is a direct correlation between brain activity and cognition Biochemical imbalances can affect behaviour Brain physiology can affect behaviour What exactly are some of the neurotransmitters which are so critical for neural transmission, and are important to our discussion of Abnormal behavior?

Finally, understanding something about the actions of drugs of abuse and their routes of administration can help us understand why some psychoactive drugs are so addictive. observable] evidence) make this approach very scientific. These drugs can be prescribed in a relatively standardized manner (chlorpromazine equivalent), but neuroleptics will be less than effective on the type of schizophrenia with negative symptoms. Genes carry the instructions for the development of characteristics like intelligence, temperament and height. You need to solve physics problems.

All mental processes are brain processes, and therefore all disorders of mental functioning are biological diseases, he says. Pharmacokineticsrefers to how the body handles a drug that we take. Does Wittenberg have a strong Pre-Health professions program? A biologically-focused approach to science, policy, and practice has dominated the American healthcare system for more than three decades. Identify one similarity between mental and physical illnesses. It is also likely that eating disorders arise due to high levels of anxiety which is linked with high levels of serotonin . interfere with or alter how neurons communicate with each other. Study notes, videos, interactive activities and more! Role of the Nervous System Proponents of the biological perspective view mental illness as being a result of a malfunction in the body to include issues with brain anatomy or chemistry. They include Lisdexamfetamine, the combination of dextroamphetamine and amphetamine, and Methylphenidate (Ritalin). The approach argues that mental disorders are related to the physical structure and functioning of the brain. The first, titled Arturo Xuncax, is set in an Indian village in Guatemala. The theory suggests that mental illnesses occur due to a physical cause. Interactions between regions of the brain help to control different functions, which biological psychologists assume to be significant in determining our actions. Therefore, all that is psychological is first physiological. Key assumptions. Champaign, IL: DEF publishers. The biological approach to psychopathology accepts that disorders have a physical or organic cause. Many professionals believe that the cause of mental disorders is the biology of the brain and the nervous system. Biology has been determined to be a large factor when it comes to bipolar disorder. This approach is based on genetics, neurotransmitters and neurophysiology. Other people just do not improve with antidepressants (Ioannidis, 2008). Biological Approach Bipolar Disorder Essay Example | GraduateWay What does the biological approach focus on? ), which are typical for elderly populations (seeHilmer and Gnjidict, 2008;Pollock, Forsyth, & Bies, 2008). Moreover, there are important gene-environment interactions that are unique for every person (even twins) which help to explain why some people with a genetic predisposition toward a certain disorder develop that disorder and others do not (e.g., why one identical twin may develop schizophrenia but the other does not). The endocrine system is a slower-acting communication system that regulates the circulation of hormones, released by glands into the bloodstream. Biomedical therapy involves medication and/or medical procedures to treat psychological disorders. Most researchers conclude that anxiety is genetic but can also be influenced by environmental factors. Remarkably, epigenetic DNA modifications have been identified that may underlie the long-lasting effects of environment on biological functions. Biological Approach To Psychology Essay - 451 Words | Cram Psychology - Biological Explanation of Eating Disorders A diathesis is not always a biological vulnerability to an illness; some diatheses may be psychological (e.g., a tendency to think about life events in a pessimistic, self-defeating way).

Types of biological therapy include immunotherapy (such as cytokines, cancer treatment vaccines, and some antibodies) and some targeted therapies. According to Mental Health America, Electroconvulsive therapy (ECT) is a procedure in which a brief application of electric stimulus is used to produce a generalized seizure. Patients are placed on a padded bed and administered a muscle relaxant to avoid injury during the seizures. But this is muchmoredifficult for a cigarette smoker.

A key debate in psychological study over the past century has been whether or not neuropsychology - the study of the brain - and looking solely at the chemical compositions and reactions within it can explain animal or human behavior. The combination of genetic association maps studies with epigenome-wide developmental studies may help identify novel molecular mechanisms to explain features of inheritance of personality traits and transform our understanding of the biological basis of psychology. Abraham Maslow developed the hierarchy of needs because he did not believe that the conditioning theories adequately portrayed the complexity of human behavior.
