मानसिक चिकित्सा

From Wikipedia

Psychiatry is a medical speciality dealing with the diagnosis and treatment of emotional, cognitive, and behavioral disorders and whose primary goal is the relief of mental suffering and improvement of mental well-being. This is sometimes done by first doing a thorough diagnostic assessment of the person from a biological, psychological, and social/cultural perspective. An illness or problem can then be treated or managed by medication (usually) or other somatic treatments or by various forms of psychotherapy (sometimes). Psychotherapies assist people to gain insight into their problem as well as their relationships with others.

The name derives from the Greek for "healer of the spirit". In the United States, it is practised by people, termed psychiatrists, holding M.D. or D.O. degrees.

While all clinicians encounter patients with mental illnesses and any of them may treat it, psychiatrists specialize in these areas. They are specifically trained to understand the biological underpinnings of mental illness as well as the contributions of medical illnesses to psychiatric symptoms. Treatment can involve medication, psychotherapy (such as cognitive behaviour therapy, interpersonal therapy, and psychodynamic psychotherapy), and psychosocial interventions. The majority of modern treatments involve medication.

[परिवर्तन्] Practice of psychiatry

Psychiatry is one of the medical disciplines that involve the diagnosis and medication of mental and behavioral disorders such as clinical depression, bipolar disorder, schizophrenia and anxiety disorders.

Most psychiatric illnesses cannot currently be cured. While some have short time courses and only minor symptoms, many are chronic conditions which can have a significant impact on a patients' quality of life and even life expectancy, and as such may require long-term or life-long treatment. Efficacy of medication for any given condition is also variable from patient to patient, with some patients having complete resolution of symptoms and others unfortunately having poor or minimal response to even the strongest measures. The majority of patients will fall somewhere in between.

In general, psychiatric treatments have changed over the past several decades, beginning with the advent of modern psychiatric medications (see History section, below). In the past, psychiatric patients were often hospitalized for six months or more, with some cases involving hospitalization for many years. Today, most psychiatric patients are managed as outpatients. If hospitalization is required, the average hospital stay is around two to three weeks, with only a small number of cases involving long-term hospitalization.

The field of psychiatry itself can be divided into various subspecialties. These include:

• Child and adolescent psychiatry
• Adult psychiatry
• Psychiatry of Old Age (Psychogeriatrics)
• Learning disability
• Consultation-liaison psychiatry
• Emergency psychiatry
• Addiction psychiatry
• Forensic psychiatry

Practicing psychiatrists may specialize in certain areas of interest such as psychopharmacology, mood disorders, neuropsychiatry, eating disorders, psychiatric rehabilitation, crisis assessment and treatment, early psychosis intervention, community psychiatry (home treatment and outreach) and various forms of psychotherapy such as psychodynamic therapy and cognitive behavioral therapy.

Individuals with mental illness are commonly referred to as patients when seen by physicians but may also be called clients, especially when treated privately by allied healthcare professionals. They may come under the care of a psychiatrist or other psychiatric practitioners by various paths, the two most common being self-referral or referral by a primary-care physician. Alternatively, a patient may be referred by hospital medical staff, by court order, involuntary commitment, or, in the UK and Australia, by sectioning under a mental health law.

Whatever the circumstance of their patient's referral, a psychiatrist first assesses their patient's mental and somatic condition. This usually involves interviewing the patient and often obtaining information collated from other sources such as other health and social care professionals, relatives, associates, law enforcement and emergency medical personnel and psychiatric rating scales. Physical examination is usually performed to establish or exclude other illnesses (e.g. thyroid dysfunction or brain tumors) or identify any signs of self-harm. Blood tests and medical imaging may be also performed. However, a study of the CAT scans of 397 psychiatric patients found no anomaly clinically related to the patients' psychiatric condition and concluded, "the pretest probability of finding a space-occupying lesion or other pertinent abnormality in patients presenting with psychiatric illnesses in this retrospective study appears not to be greater than that of the general population. The outcome of this study could be implemented to develop a clinical pathway for limiting assessment by CT for possible organic pathology in acute psychiatric illness." [1]

Various forms of medication, therapy and counseling deal with mental and behavioral conditions. Psychotherapy may be used for many conditions, either exclusively or in combination with medication. In the United States, only physicians, medical psychologists^[1], nurse practitioners, or physician assistants may prescribe mental health medication. In some countries, mental health medication may only be prescribed by physicians. Commencing treatment with medication requires the patient to agree to this treatment (although in many countries the law provides overriding circumstances) and that they will follow the dosage prescribed. Like all medications, psychiatric medications can produce side-effects in patients and hence often involve ongoing therapeutic drug monitoring, for instance full blood counts or, for patients taking lithium salts, serum levels of lithium. Electroconvulsive therapy (ECT) is sometimes administered for serious and disabling conditions, especially those unresponsive to medication. ECT has drawn criticism from anti-psychiatry groups despite evidence for its efficacy.

Psychiatric patients may be either inpatients or outpatients. Psychiatric outpatients periodically visit their psychiatrist for consultation in his or her office, usually for an appointment lasting thirty to sixty minutes. These consultations normally involve the psychiatrist interviewing the patient to update their assessment of the patient's condition and management of any medication. The psychiatrist may also provide psychotherapy. The frequency with which a psychiatrist sees patients varies widely, from days to months, depending on the type, severity and stability of each patient's condition, and depending on what the psychiatrist and patient decide would be best.

Psychiatric inpatients are patients admitted to a hospital to receive psychiatric care, sometimes involuntarily. In North America, the criteria for involuntary admission vary with jurisdiction. It may be as broad as having a mental disorder and being capable of mental or physical deterioration or as narrow as a patient being considered to be an immediate danger to themselves or others. In the UK, involuntary admission is limited to this narrow criterion.

Once in the care of a hospital, patients are monitored, given medication and tested by a psychologist. If necessary, they are prevented from harming themselves or others. Hospitalized patients are increasingly being managed in a multidisciplinary fashion, meaning patients may encounter a variety of nursing staff, occupational therapists, psychotherapists, social workers and other healthcare professionals.

[परिवर्तन्] The DSM system

In the United States, the standard system of psychiatric diagnoses is given in the Diagnostic and Statistical Manual of Mental Disorders (known as the DSM), overseen and revised by the American Psychiatric Association. It is currently in its fourth revised edition (IV-TR, published 2000) and is based on five axes:

• Axis I: Psychiatric disorders
• Axis II: Personality disorders / mental retardation
• Axis III: General medical conditions
• Axis IV: Social functioning and impact of symptoms
• Axis V: Global Assessment of Functioning (described using a scale from 1 to 100)

Common axis I disorders include substance dependence and abuse (e.g. alcohol dependence); mood disorders (e.g. depression, bipolar disorder); psychotic disorders (e.g. schizophrenia, schizoaffective disorder); and anxiety disorders (e.g. post-traumatic stress disorder, obsessive-compulsive disorder). Axis II disorders include borderline personality disorder, schizotypal personality disorder, avoidant personality disorder and antisocial personality disorder.

The intention is to create a set of diagnoses that are replicable and meaningful, although the categories are broad and many of the symptoms overlap. While the system was originally intended to enhance research into both diagnosis and treatment, the nomenclature is now one of two standards widely used by clinicians, administrators and insurance companies in many countries. However, it has been critiqued for being vague, poorly defined and lacking proper scientific foundation ^[2].

ICD-10 (International Classification of Diseases)-the ICD 10 published by the WHO is used world wide and is considered atleast on par with the DSM system though the lack of a case example version is telling. The ICD 10 is comparable in accuracy of diagnoses excepting certain categories which are more due to social differences in the countries themselves.For example disruptive disorders of childhood are diagnosed to a greater extent in the U.S than the U.K. The two systems were designed to be compatible generally but there are inherent anomalies in both.

[परिवर्तन्] Contrast with psychology

Main articles: Psychology, Clinical Psychology Psychology is the study of human behavior and thought processes. Psychology is as much a field of academic study (like biology or sociology) as a profession, and as a whole, is concerned with the whole range of everyday human behavior as much as it is the study of mental illness. Clinical psychology is the application of psychology to problematic mental distress in a health and social care context. Psychiatrists, being medical doctors, can prescribe drugs, while psychologists cannot. Template:See also

[परिवर्तन्] Professional requirements

In general, being a qualified medical practitioner is a prerequisite for entering training to become a psychiatrist, though the process and time spent may vary from country to country.

In the United States, psychiatrists can be board certified as specialists in their field. After completing four years of college, then 4 years of medical school, these physicians practise as psychiatry residents for another four years. Psychiatry residents are required to complete at least four post-graduate months of internal medicine or pediatrics and two months of neurology during the first year. After completing their training, psychiatrists take written and then oral board examinations administered by the American Board of Psychiatry and Neurology (ABPN).

In Australia, after completing a medical degree and two years of experience as a junior doctor (intern, then RMO or Resident Medical Officer), doctors must complete five years as a psychiatry registrar, including six month rotations in child and consultation-liaison psychiatry, and pass written and clinical exams prior to gaining qualifications as a Consultant Psychiatrist. The professional body of psychiatrists is known as the RANZCP (Royal Australian and New Zealand College of Psychiatrists).

In the United Kingdom, people gain a five-year bachelor's degree in general physical medicine, after which they are allowed the title 'doctor'; then they work as a senior house officer (SHO) in psychiatry for 2-3 years while sitting postgraduate exams, after which they may apply for a specialist registrar post, which may be in any one of several areas of specialization within psychiatry. There are several different areas of specialization in which one may train as a specialist registrar (the 3-4 years of career advancement required before becoming a senior physician or consultant), which are general adult psychiatry, child and adolescent psychiatry, psychogeriatrics, forensic psychiatry, and psychotherapy. After this period as a specialist registrar, one has to be approved by the Royal College of Psychiatrists as a specialist in the chosen field before going on to apply for a consultant post in that field. In other countries, similar rules usually apply.

Some psychiatrists specialize in helping certain age groups; child and adolescent psychiatrists work with children and teenagers in addressing psychological problems. Those who work with the elderly are called geriatric psychiatrists, or in the UK, psychogeriatricians. Those who practise psychiatry in the workplace are called industrial psychiatrists in the US ("occupational psychology" is the name used for the most similar discipline in the UK). Psychiatrists working in the courtroom and reporting to the judge and jury (in both criminal and civil court cases) are called forensic psychiatrists, who also treat mentally disordered offenders and other patients whose condition is such that they have to be treated in secure units.

[परिवर्तन्] History

Psychiatric illnesses are sometimes characterized as disorders of the mind rather than the brain, although the distinction is not always obvious and has changed in the last few decades as understanding of the treated illnesses grew. Many conditions have been linked to biological or chemical abnormalities in the brain's psychology, but for some conditions the etiology and pathogenesis are still the subject of intense research.

For a long period of history, neurology and psychiatry were a single discipline, and following their division the tremendous advances in neurosciences (especially in genetics and neuroimaging) recently are bringing areas of the two disciplines back together. Indeed, in a 2002 review article in the American Journal of Psychiatry, Professor Joseph B. Martin, Dean of Harvard Medical School and a neurologist by training, wrote that "the separation of the (neurological versus psychiatric disorders) is arbitrary, often influenced by beliefs rather than proven scientific observations. And the fact that the brain and mind are one makes the separation artificial anyway." ^[3] One example of this is the overlap between the two fields in the treatment of illnesses such as Alzheimer's disease.

Psychiatry was at first a pragmatic discipline that was part of general medicine, combining medicine and practical psychology. The work of Emil Kraepelin laid the foundations of scientific psychiatry. A neurologist, Sigmund Freud, used these same powers of medically based observation to develop the field of psychoanalysis. For many years, particularly during the mid-twentieth century, Freudian theories dominated psychiatric thinking.

The discovery of lithium carbonate as a treatment for bipolar disorder (and, shortly thereafter, by the development of typical antipsychotics for treatment of schizophrenia), followed by the development of fields such as molecular biology and tools such as neuroimaging has led to psychiatry re-discovering its origins in physical and observational medicine.

During the 20th Century psychiatry was often used by totalitarian regimes as part of a system to enforce political control. Typical examples include Nazi Germany[2], the Soviet Union under the name of Psikhushka, and the apartheid system in South Africa[3]. Is is apparently still used that way in China [4] and other countries.

[परिवर्तन्] Deinstitutionalization

During the last 40 years, the institutional confinement of people with the most severe and persistent forms of mental illness has been steadily declining. Among the reasons for this trend are advances in psychopharmacology, increases in public financial assistance for people with severe disabilities, and developments in community mental health treatment (for example, see psychosocial rehabilitation and assertive community treatment). Finally, this is the preference of the majority of the chronically mentally ill.

[परिवर्तन्] Further considerations

[परिवर्तन्] Anti-psychiatry

मुख्य पृष्ठ : Anti-psychiatry

Unlike most other areas of medicine, there exist movements opposed to the practices of – and, in some cases, the existence of – psychiatry. These movements mostly originated in the 1960s and 1970s, led by figures such as David Cooper, Thomas Szasz and R. D. Laing. In 1999, psychiatrist Peter Breggin founded a scholarly journal devoted exclusively to criticism of bio-psychiatry, Ethical Human Psychology and Psychiatry^[4].

Some mental health professionals sympathetic to anti-psychiatric views claim that there are no known biological markers for many if not all the disorders the DSM purportedly identifies^[5]. Also, though psychiatrists generally accept a medical model of mental disorders, some professionals and patients advocate a trauma model, especially as regards schizophrenia^[6][7][8].

[परिवर्तन्] Other criticisms

• Criticism has been made regarding the need for improvement in psychiatric medications, as illustrated by studies of pharmacogenetic polymorphism showing that people of various ethnicities, for example one third of African American and Asian groups, have an increased risk of side effects and toxicity^[9].

• As in any medical specialty, different individuals respond differently to a given drug. Unfortunately, side effects to psychiatric drugs are common and sometimes severe. Combined with the time period of therapeutic effect which generally takes between two and six weeks (but can draw out to several months), this can lead to prolonged periods where patients are sufferring distressing side effects.

• Critics also question whether psychiatric drugs are disorder- or problem-specific in the way that is claimed (Moncrieff and Cohen, 2005).

• The high rate of methylphenidate (Ritalin) use among school children in the U.S. has come under greater scrutinyTemplate:Fact. However this may be partly due to the shortage of child and adolescent psychiatrists (A Report of the Surgeon General, 2001) who are able to regulate such prescriptions.

• Critics claim that there are problems in terms of diagnostic reliability, including misdiagnosis (Williams et al, 1992; McGorry et al, 1995; Hirschfeld et al, 2003]), especially when comparing the criteria of the different psychiatric manuals (van Os et al, 1999). Some critics add that the criteria for many "mental illnesses" are openly culturally biased, or are extremely subjective and create essentially random diagnoses. See Schizophrenia.

• Another concern centers on the issue of involuntary commitment, which centers on issues of civil liberties and personal freedoms. In the U.S. someone may be involuntarily detained for psychiatric examination for a period of time (usually 24 to 72 hours depending on the state) if a government official declares the subject to be a danger to himself or others. With the attestation of an examining physician that a patient meets strict criteria of dangerousness to himself or others resulting from symptoms of mental illness, a judge may extend this commitment. Opposition to involuntary commitment is diverse and includes simple arguments that involuntary commitment is now or is inherently unconstitutional. The laws regarding the involuntary treatment of children vary widely from state to state^[10].
