Mental health




The recognition and understanding of mental health conditions have changed over time and across cultures and there are still variations in definition, assessment and classification, although standard guideline criteria are widely used. In many cases, there appears to be a continuum between mental health and mental illness, making diagnosis complex.:39 According to the World Health Organization (WHO), over a third of people in most countries report problems at some time in their life which meet criteria for diagnosis of one or more of the common types of mental disorder. Corey M Keyes has created a two continua model of mental illness and health which holds that both are related, but distinct dimensions: one continuum indicates the presence or absence of mental health, the other the presence or absence of mental illness. For example, people with optimal mental health can also have a mental illness, and people who have no mental illness can also have poor mental health.

Classifications

There are currently two widely established systems that classify mental disorders: ICD-10 Chapter V: Mental and behavioural disorders , since 1949 part of the International Classification of Diseases produced by the WHO, the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) produced by the American Psychiatric Association (APA) since 1952. Both of these list categories of disorder and provide standardized criteria for diagnosis. They have deliberately converged their codes in recent revisions so that the manuals are often broadly comparable, although significant differences remain. Other classification schemes may be used in non-western cultures, for example the Chinese Classification of Mental Disorders , and other manuals may be used by those of alternative theoretical persuasions, for example the Psychodynamic Diagnostic Manual . In general, mental disorders are classified separately from neurological disorders, learning disabilities or intellectual disability. Unlike ...

Psychiatrists seek to provide a medical diagnosis of individuals by an assessment of symptoms, signs and impairment associated with particular types of mental disorder. Other mental health professionals, such as clinical psychologists, may or may not apply the same diagnostic categories to their clinical formulation of a client's difficulties and circumstances. The majority of mental health problems are, at least initially, assessed and treated by family physicians (in the UK general practitioners) during consultations, who may refer a patient on for more specialist diagnosis in acute or chronic cases. Routine diagnostic practice in mental health services typically involves an interview known as a mental status examination, where evaluations are made of appearance and behavior, self-reported symptoms, mental health history, and current life circumstances. The views of other professionals, relatives or other third parties may be taken into account. A physical examination to check fo...

Management

Treatment and support for mental disorders is provided in psychiatric hospitals, clinics or a range of community mental health services. In some countries services are increasingly based on a recovery approach, intended to support individual's personal journey to gain the kind of life they want. There are a range of different types of treatment and what is most suitable depends on the disorder and the individual. Many things have been found to help at least some people, and a placebo effect may play a role in any intervention or medication. In a minority of cases, individuals may be treated against their will, which can cause particular difficulties depending on how it is carried out and perceived. Compulsory treatment while in the community versus non-compulsory treatment does not appear to make much of a difference except by maybe decreasing victimization. Lifestyle Lifestyle strategies, including dietary changes, exercise and quitting smoking may be of benefit. Therapy There is ...
