Psychiatric Disorders

Psychiatric disorders are disorders that affect psychological functioning. These disorders range from mild to severe and can, at times, be very difficult to diagnose. Depending on the disorder and its severity the treatment for each may vary. A few commonly known psychiatric disorders include Schizophrenia, Depression and Mania, Anxiety disorder and Tourette syndrome. Schizophrenia is an extremely complex disorder with several different types including; catatonic, paranoid, disorganized, undifferentiated and residual. Schizophrenia is characterized by positive and negative symptoms. The symptoms are considered positive or negative because they are behaviors that are either “bizarre” excesses or lacking in a persons character. (Comer, 2011). Symptoms may include things like hallucinations, delusions, illogical speech or thought, bag hygiene, reduction in emotional expression, reduced speech and no motivation. There are different theories behind the causes of schizophrenia but the main biological theories include brain abnormalities or chemical imbalance with the dopamine neurotransmitter, genetics or even the possibility that exposure to a virus during fetal development is the cause. (Comer, 2011). Antipsychotic drugs are typically used to treat this disorder and can greatly reduce symptoms. There are the conventional antipsychotic and the newer atypical antipsychotic drugs. While each has their ups and down the conventional drugs tend to cause motor disturbances while the atypical neuroleptics can cause weight gain, diabetes and issues with fat regulation. Many people experience depression at one point during their lives. Depression is an affective disorder that can be unipolar or bipolar. When depression is bipolar it has periods of depression followed by periods of extreme highs or manic episodes. The theories behind…...

It doesn’t discriminate because it can affect all races and cultures. It starts in the early adulthood stage. Schizophrenia has positive and negative symptoms. Some positive symptoms are delusions, hallucinations, and odd behavior. Some negative symptoms include alogia (reduce of speech, and anhedonia (inability to experience pleasure). Drugs that lesson these effects are chlorpromazine, haloperidol, Prolixin, Navane. These drugs work by altering the activity of chemicals in the brain called neurotransmitters. They transmit signals from one brain cell to another. These drugs have side effects like many other drugs. Such side effects can include muscle spasms, tremor, dry mouth, blurred vision, and drowsiness. There are some symptoms that are more on the negative side. A person can have a long term side effect called TD (Tardive Dyskinesia). This is where a person can have involuntary movements which can affect the lips, mouth, tongue and sometimes the trunk of the body. It occurs in 15 to 20 percent of patients who are taking the old antipsychotic drugs. The symptoms are so......

...Psychiatric Disorders, Diseases, and Drugs Psychiatric Disorders, Diseases, and Drugs Psychiatric disorders and diseases are those conditions defined by the presentation of abnormal behavior. Abnormal behavior is often defined by the mental health profession as behavior which is unusual or atypical. In addition, the individual suffering from a psychiatric disease or disorder may have difficulty with perception of reality or the hindered ability to interpret reality which may cause significant personal distress, self defeating behavior or otherwise dangerous behavior to oneself or others. Often times these behaviors are also socially unacceptable to ones specific culture (Nevid & Rathus, 2005). Schizophrenia is one of the most complex psychiatric diseases of all time. The disease name means “the splitting of psychic functions” (Pinel, 2007, p.481). The individual diagnosed with schizophrenia will commonly present symptoms which include bizarre delusions, inappropriate affect, hallucinations, incoherent thoughts and odd behavior with these symptoms varying in severity (Pinel, 2007). Various theories on schizophrenia have come to fruition over time. It is the belief of some researchers that schizophrenia has a genetic predisposition and that combined with experiences involving immense trauma or stress the disease can be triggered for development. In addition, those individuals with a genetic predisposition for schizophrenia who suffer hindered neurodevelopment......

Schizophrenia is a group of severe brain disorders in which people interpret reality abnormally. Schizophrenia may result in some combination of hallucinations, delusions, and disordered thinking and behavior. About one percent of Americans have this illness. People with the disorder may hear voices other people don't hear. Contrary to some popular belief, schizophrenia isn't split personality or multiple personality. The word "schizophrenia" does mean "split mind," but it refers to a disruption of the usual balance of emotions and thinking. They may believe other people are reading their minds, controlling their thoughts, or plotting to harm them. This can terrify people with the illness and make them withdrawn or extremely agitated. People with schizophrenia may not make sense when they talk. They may sit for hours without moving or talking. Sometimes people with schizophrenia seem perfectly fine until they talk about what they are really thinking. Families and society are affected by schizophrenia too. Many people with schizophrenia have difficulty holding a job or caring for them selves, so they rely on others for help. Treatment helps relieve many symptoms of schizophrenia, but most people......

...Psychiatric disorders are defined in our text as disorders of psychological function sufficiently severe to require treatment. The clinical psychologist or the psychiatrist has their work cut out for them when it comes to diagnosing psychiatric disorders. Each disorder has its own diagnosis, treatment method, and medication. Schizophrenia can make it hard to live everyday life without treatment. Schizophrenia can affect how you think, react, and just live in the world. With schizophrenia they have two categories for symptoms, positive and negative. Positive symptoms represent an excess or distortion of normal function. Negative symptoms represent a reduction or loss of normal function. Some positive symptoms include; delusions, hallucinations, inappropriate affect, incoherent speech or thought, and odd behavior. The negative symptoms include; affective flattening, alogia, avolition, and anhedonia. One way that clinical psychologist and psychiatrist determine if a person has schizophrenia is if they have any two of the symptoms occur for one month. The main symptoms that are looked for are delusions that are bizarre or an hallucination that includes voices. One of the biggest treatments for schizophrenia are antipsychotic drugs.

...Psychiatric Disorders, Diseases, and Drugs By Stacy Davis Psych 240 Week 8 Stephanie Neuhring There are many psychological disorders and diseases that affect many people in this world and some of the people with these diseases are being treated with certain medications. Some of the disease most commonly treated is schizophrenia which means the splitting of psychic functions. Antipsychotic drugs are the cornerstone in the management of schizophrenia. Although, these medications don’t cure this disease they greatly reduce the symptoms and allow the patient to function better. The first antipsychotic drug was Thorazine, it was made by accident and was used to treat schizophrenia. The first antischizophrenic drug, chlorpromazine. Chlorpromazine was originally developed as an antihistamine. Soon after other medications such as; Haldol, Prolixin, Navanem Loxapine, Stelazine, Trilafon, and Mallaril were used also. These drugs are known as “neuroleptics” (meaning, “take the neuron”) because these treat positive symptoms they cause cognitive dulling and involuntary movements, among other side effects. The older drugs are not as effective against negative symptoms such as apathy, decreased motivation, and lack of emotional expressiveness. In 1989, new antopsychotics were developed, these were called atypical antipsycoltics, and these had fewer side effects which include, muscular rigidity, painful spasms, restlessness, and tremors. The first new drug, Clozaril is the only one......

... Psychiatric Disorders, Diseases, and Drugs Barb Parker PSY/240 April 7, 2012 Rebecca Gazda Psychiatric disorders and neuropsychological disorders were, in the past, thought to be caused by two different abnormalities (Pinel, 2009). Now there is enough evidence to qualify both disorders as disorders of dysfunctional brains (Pinel, 2009). There are a few differences in the causes; psychiatric disorders are more influenced by experience and are harder to diagnose (Pinel, 2009). This summary will briefly describe the different theories with the psychiatric disorders of schizophrenia, bipolar disorder, panic disorder, bulimia nervosa, and Tourette syndrome, as well as drug therapies used to treat them. Schizophrenia in itself has no clear definition because of its relationship with other brain disorders (Pinel, 2009). Because of the various symptoms produced by schizophrenia, such as delusions, hallucinations, inappropriate reactions to events, illogical thinking, and periods of catatonia, many professional refer to the disorder as schizophrenias (Pinel, 2009). There are several abstract thoughts behind the causes of schizophrenia including the developmental, genetic, and dopamine theories. The genetic theory suggests that people can be predisposed genetically to schizophrenias when certain environmental experiences interact, but it is not known how (“Schizophrenia: Current Theories”, 2011). The developmental hypothesis is based on complications......

Psychiatric Disorders and Disesases

...Psychological disorders and diseases PSY 240 November 2, 2014 Psychological disorders and diseases Schizophrenia is a severe brain disorder for which there is no cure; however, it can be managed. Although researchers are not sure what causes schizophrenia, they think a person’s environment coupled with genetics play a significant role in the development of the disease. Other factors may include abnormalities in the neurotransmitters called dopamine, and glutamate. It causes people to think abnormally, and exhibit various combinations of abnormal behavior. (Mayo clinic staff, 2014). According to Mayo clinic staff (2014), symptoms include “hallucinations, delusions, and extremely disordered thinking and behavior” (Schizophrenia). Some antipsychotic drugs are that are prescribed to treat schizophrenia are; chlorpromazine, fluphenazine, haloperidol (haldol), and perphenazine. Often there are other types of medications that are used in conjunction with the antipsychotic drugs such as antidepressants, and anti-anxiety medications. The medications and dosages are mixed and matched until the right dose and drug start to manage the symptoms based on the individual’s circumstances. Most medications only work when they are taken as prescribed. The problem with schizophrenics they rarely think they are sick, so they either choose not to take the medication as directed, or not at all. This is a problem called anosognosia.

Psychiatric Injury

...between real or imaginary/exaggerated claims. Seeing is believing and since psychiatric injury is not visible to the untrained eye, claims were long thought of as frivolous. In recent decades, however, medical identification of psychiatric injury has propelled legal recognition of it. As Gummow and Kirby JJ noted in Tame and New South Wales and Annetts v Australian Stations Pty Ltd, ‘there have been advances in the capacity of medicine to objectively distinguish the genuine from the spurious’. History of the law The history of the common law in this area heavily rests on the fear of opening the floodgates of litigation. Courts have been hesitant in recognising claims, concerned with creating indeterminate liability for plaintiffs. During the 20th century statutory law development in the area of mental harm was very slow. In 1944 NSW Parliament created a statutory cause of action for nervous shock followed by the ACT and NT in 1955. WA and all other jurisdictions continued to be governed by the common law which at this point provided that a claimant be; present at the scene and perceive the injury or death of a close relative with his/her own unaided senses. In 1984, the case of Jaensch v Coffey occurred and up until 2002 Australian common law was governed by the principles established in it. According the High Court of Australia decision claimants could recover damages for a recognisable psychiatric illness which was; a result of shock, occasioned by the death or......

Motivational Interviewing and the Psychiatric Patient

...Motivational Interviewing and the Psychiatric Patient Amanda Doyle McKendree University Motivational Interviewing and the Psychiatric Patient A nurse’s role in counseling psychiatric patients or those with emotional trouble, is to listen to the patient, assess the patient to be sure there are no thoughts of self-harm, and to guide them through their choice to make a behavior change, and to help them make that change. Psychiatric patients often have a hard time trusting others due to being judged for being different, being made fun of, and because of their own feelings about themselves. When interacting with a patient who suffers from a psychiatric illness or an emotional problem, it is best to introduce yourself first, and be firm about what is expected from nursing staff, and the patient, upfront before the conversation begins. As well, it is important to ask permission from the patient, or legal guardian if the patient is underage or not able to consent due to the psychiatric condition. Once the conversation starts, the patient should have the full undivided attention of the nurse; the nurse shouldn’t be distracted by other patient calls, her personal or work phone, or be writing during the conversation. Actively listening helps build the trust of the relationship, which is essential for getting the patient to divulge thoughts of self-harm. “MI guides the therapist to listen actively to the patient without communicating criticism, blame, or other judgements,......

Psychiatric Diagnosis

...THE RELIABILITY OF PSYCHIATRIC DIAGNOSIS Psychiatry is the branch of medicine that recognizes and treats mental illness. This science follows a medical model that is considered successful in classifying abnormal behavior. Psychiatrists need medical training in order to diagnose and treat mental disorders following the Diagnostic and Statistical Manual of Mental Disorders. However, for more than two centuries, there has been an anti-psychiatry movement that questions the reliability and helpfulness of psychiatric treatments. Many psychiatrists such as Maurice Temerlin(1968) and David Rosenhan(1973) supported some of the objections and criticisms of the anti-psychiatry movement. Rosenhan questioned the reliability of psychiatric diagnoses and accused diagnostic labels of impairing medical judgement. David Rosenhan carried out the study “On Being Sane In Insane Places” through which he wanted to prove that psychiatric diagnoses are not reliable (Rosenhan, 1973). For the first part of the study, eight sane participants (pseudo-patients) pretended to have auditory hallucinations in order to be admitted to psychiatric hospitals in different states across the United States. Participants for the experiment included three psychologists, one psychiatrist, a graduate student, a housewife, a pediatrician, and a painter. The only false information given for admission was their name, job, and the claim of recent auditory hallucinations. All other details regarding......

Psychiatric Disorders and Disease

...Psychiatric disorders differ from neuropsychological disorders. A psychiatric disorder is a type of psychological function or lack of, relating to common functionality in an individual. A neuropsychological disorder is different yet hard to separate due to defining difficulties leading to unclear differences between the two types of disorders. Researchers show that the main difference between the two disorders begins with the archaic mind-brain. In other words the neuropsychological disorders are thought to be a product of a dysfunctional brain. Psychiatric disorders are those assumed to be products of dysfunctional minds, absent in the brains pathology. In recent studies we have learned these two types of disorders are closely related however, there tends to be some differences between them such as experiential factors. Some common psychiatric disorders are schizophrenia, depression, mania, anxiety disorders, and tourette syndrome. No matter what research shows us as far as relation of two types of disorders, it is important to remember how serious some of them can be. In order to understand some of the disorders one should know about what they do and what happens to the individual who suffers from them including drugs that can help or negative effects of association by certain drugs used in common psychiatric disorders. The term schizophrenia was coined in the early 20th century, meaning- splitting of psychic functions. Schizophrenia is the disease which most......
