The definition types and treatment of schizophrenia

Types and causes of mental disorders Classification and epidemiology Psychiatric classification attempts to bring order to the enormous diversity of mental symptoms, syndromes, and illnesses that are encountered in clinical practice. Epidemiology is the measurement of the prevalence, or frequency of occurrence, of these psychiatric disorders in different human populations.

Much of this information is gathered by the mental health practitioner e. The practitioner may administer any of several psychological tests to the patient and may supplement these with a physical and a neurological examination. Diagnosis is as important in mental health treatment as it is in medical treatment.

Classification systems in psychiatry aim to distinguish groups of patients who share the same or related clinical symptoms in order to provide an appropriate therapy and accurately predict the prospects of recovery for any individual member of that group.

Thus, a diagnosis of depression, for example, would lead the practitioner to consider antidepressant drugs when preparing a course of treatment. Sometimes two words with quite different derivations have come to mean almost the same thing—for example, dementia praecox and schizophrenia.

Psychiatry is hampered by the fact that the cause of many mental illnesses is unknown, and so convenient diagnostic distinctions cannot be made among such illnesses as they can, for instance, in infectious medicinewhere infection with a specific type of bacterium is a reliable indicator for a diagnosis of tuberculosis.

But the greatest difficulties presented by mental disorders as far as classification and diagnosis are concerned are that the same symptoms are often found in patients with different or unrelated disorders and a patient may show a mix of symptoms properly belonging to several different disorders.

Thus, although the categories of mental illness are defined according to symptom patterns, course, and outcome, the illnesses of many patients constitute intermediate cases between such categories, and the categories themselves may not necessarily represent distinct disease entities and are often poorly defined.

The 10th revision of the former, published inis widely used in western Europe and other parts of the world for epidemiological and administrative purposes. Its nomenclature is deliberately conservative in conception so that it can be used by clinicians and mental health care systems in different countries.

The 11th revision ICD was slated for publication in The DSM, by contrast, has undergone five revisions since its introduction in ; the most recent version, DSM-5, was presented in The DSM differs from the ICD in its introduction of precisely described criteria for each diagnostic category; its categorizations are based upon the detailed description of symptoms.

Its detailed descriptions of diagnostic criteria have been useful in eradicating the inconsistencies of earlier classifications. However, there are still some major problems in its everyday clinical use.

These terms have been and still are widely used to distinguish between classes of mental disorders, though there are various mental illnesses, such as personality disordersthat cannot be classified as either psychoses or neuroses.

Furthermore, its use of broad diagnostic criteria and its lack of inclusion of diagnostic criteria based on known biological factors have been sources of criticism.

Psychoses Psychoses are major mental illnesses that are characterized by severe symptoms such as delusionshallucinationsdisturbances of the thinking process, and defects of judgment and insight.

Persons with psychoses exhibit a disturbance or disorganization of thoughtemotion, and behaviour so profound that they are often unable to function in everyday life and may be incapacitated or disabled. Such individuals are often unable to realize that their subjective perceptions and feelings do not correlate with objective reality, a phenomenon evinced by persons with psychoses who do not know or will not believe that they are ill despite the distress they feel and their obvious confusion concerning the outside world.

Traditionally, the psychoses have been broadly divided into organic and functional psychoses. Organic psychoses were believed to result from a physical defect of or damage to the brain. Functional psychoses were believed to have no physical brain disease evident upon clinical examination.

Much research suggests that this distinction between organic and functional is probably inaccurate. Most psychoses are now believed to result from some structural or biochemical change in the brain.

Neuroses Neuroses, or psychoneurosesare less-serious disorders in which people may experience negative feelings such as anxiety or depression. Their functioning may be significantly impaired, but personality remains relatively intact, the capacity to recognize and objectively evaluate reality is maintained, and they are basically able to function in everyday life.

In contrast to people with psychoses, neurotic patients know or can be made to realize that they are ill, and they usually want to get well and return to a normal state. Their chances for recovery are better than those of persons with psychoses. The symptoms of neurosis may sometimes resemble the coping mechanisms used in everyday life by most people, but in neurotics these defensive reactions are inappropriately severe or prolonged in response to an external stress.

Anxiety disorders, phobic disorder exhibited as unrealistic fear or dreadconversion disorder formerly known as hysteriaobsessive-compulsive disorderand depressive disorders have been traditionally classified as neuroses.

Epidemiology Epidemiology is the study of the distribution of disease in different populations. Prevalence denotes the number of cases of a condition present at a particular time or over a specified period, while incidence denotes the number of new cases occurring in a defined time period.

Epidemiology is also concerned with the social, economic, or other contexts in which mental illnesses arise. The understanding of mental disorders is aided by knowledge of the rate and frequency with which they occur in different societies and cultures. Looking at the worldwide prevalence of mental disorders reveals many surprising findings.

It is remarkable, for instance, that the lifetime risk of developing schizophrenia, even in widely different cultures, is approximately 1 percent.

Types and causes of mental disorders

Gradual historical changes in the incidence and prevalence of particular disorders have often been described, but it is very difficult to obtain firm evidence that such changes have actually occurred. On the other hand, prevalence has been seen to increase for a few syndromes because of general changes in living conditions over time.

For example, dementia inevitably develops in some 20 percent of those persons over age 80so, with the increase in life expectancy common to developed countries, the number of people with dementia is bound to increase.

There also seems to be some evidence of an increased prevalence of mood disorders over the past century.Schizophrenia Information > History of Schizophrenia: History of Schizophrenia: The word "schizophrenia" is less than years old.

However the disease was first identified as a discrete mental illness by Dr. Emile Kraepelin in the and the illness itself is generally believed to have accompanied mankind through its history.

A treatment program that includes treatment for both illnesses is critical for recovery because misuse of drugs and alcohol can interfere with treatment for schizophrenia.

Drug abuse can increase the risk of suicide, trauma, and homelessness in people with schizophrenia as well as increase the risk of developing other mental illnesses. The five major types of schizophrenia recognized by the DSM-IV included the disorganized type, the catatonic type, the paranoid type, the undifferentiated type, and the residual type.

Disorganized schizophrenia was characterized by inappropriate emotional responses, delusions or hallucinations, uncontrolled or inappropriate laughter, and. Edema defined medically as the swelling from fluid accumulation the body tissues due in certain areas of the body, for example, the legs, feet, ankles, or hands.

There are a number of types of edema. Pitting edema occurs when an area that is filled with excess fluid is pressed upon and the indentation caused persists for some time after the release of the pressure.

Hypomania (literally "under mania" or "less than mania") is a mood state characterized by persistent disinhibition and elevation (euphoria). It may involve irritation, but less severely than full attheheels.coming to DSM-5 criteria, hypomania is distinct from mania in that there is no significant functional impairment; mania, by DSM-5 definition, does include significant functional impairment.
