Mental illness is a clinically diagnosable disorder that significantly interferes with an individual’s cognitive, emotional or social abilities. The diagnosis of mental illness is generally made according to the classification systems of the Diagnostic and Statistical Manual of Mental Disorders or the International Classification of Diseases.

Mental health, its causes and treatments have varied over time with different time periods and cultures.

Since Neolithic times there have been suggestions that they used to drill holes in the skull to treat mental illness. These operations involving the opening of the skull were believed to facilitate the exit of evil spirits that caused mental illness. However, in the middle ages theories arose that the four humours caused mental illness. These were black bile (faeces), yellow bile (urine), phlegm and blood. Then in 1600 Native Americans summoned supernatural powers to treat those that were considered mentally ill but later in 1600’s mental illness was commonly thought to signify a witch or someone that was possessed by a demon. Cotton Mather suggested that physical explanations lead to mental illness. Mental illness became more common after World War one as it led to a rise in mental disorders such as ‘shell shock’ and this was the time that covert euthanasia projects took place leading to the annihilation of ‘undesirables’ such as Jews or Homosexuals.

In the 1930’s hospitals began to inject insulin into mentally ill patients to induce temporary comas or shock as a treatment for schizophrenia. By the 1940’s other treatments were introduced such as electrotherapy. The process involved applying electrical current to the brain to treat mentally ill patients. Nearly 50 years later in 1990 brain imaging was used to learn more about the development of mental disorders leading to the DSM and ICD developing new criteria, which lead to a huge rise of ‘official’ diagnosis. Through the 1990’s SSRI antidepressants became the most prescribed drug for depression in the world.

The mental health act of 1983 was a big landmark in the history of mental health. It defines a mental disorder as a ‘metal illness, arrested or incomplete development of mind, psychopathic disorder and any other disorder or disability of the mind’. Under the mental health act (MHA) a small proportion of mentally ill patients can be detained. This is ‘either in the interests of their own safety or with a view to the protection of other persons’. The 2002 MHA added the right for a patient to refuse treatment. Under the mental health act there is sectioning.

Sectioning is when an individual can be kept in an institution from 28 days (under Section 2) up to 6 months or longer (under Section 3). They can only be sectioned if they have a metal illness, severe mental impairment or psychotic disorder but only if treatment is necessary. The treatment aims to prevent deterioration or ease the symptoms of the individual’s condition. To be sectioned an approved social worker must apply but only if they have support form 2 GP’s. On top of this the sectioning can only happen if the closest available relative doesn’t object. However, if the relative objects to sectioning but has an unreasonable or invalid explanation there is a process to overrule them.

The ideas of mental health have changed over time, as there has become more knowledge of how to diagnosis and treat mental illness due to technology and the understanding of cognitive processes.

Abnormality can be measured by one of four definitions. These are Statistical Infrequency, Deviation from Social Norms, Failure to function adequately and Deviation from ideal mental health

 

The first is statistical infrequency. This is when a population is represented on a bell curve graph.
