Classification systems in psychiatry

From WikiLectures

Classification systems in psychiatry aim at the international standardisation of mental disorders. [1] They therefore provide a common language to all employees in the field, they serve to communicate effectively and make the right diagnosis. Among other things, they also simplify the subsequent epidemiological processing of data.

Classification systems[edit | edit source]

There are two main approaches used in classification systems:

  • Categorical – distinguishes qualitatively different phenomena, which differ from each other in clearly given criteria.
  • Dimensional – determines the extent to which a person expresses a given flag and its frequency.[2]

The basic systems used include:

1) MKN, International Classification of Diseases ( mainly Europe including Czech Republic):

  • 1893 – The international list of causes of death, in Chicago, there were no mental disorders in it yet;
  • 1938 – 5. revision with a chapter "Diseases of the nervous system and sensory organs" containing 4 mental disorders: mental retardation, schizophrenia, manic-depressive psychosis and other mental disorders;
  • 1948 – 6. revision, ICD, separate chapter devoted to psychiatry added, sponsorship taken over by WHO;


2) DSM, Diagnostic and statistical manual (USA):

  • 1952 Diagnostic and Statistical Manual of Mental Disorders (DSM-I) produced by the American Psychiatric Association;
  • America did not like the ICD and its division of mental illnesses - they have a phenomenological categorization - each disorder is defined by a certain number of diagnostic criteria;
  • DSM-III also influenced the 10th revision of the ICD (1993);
  • 2013 current fifth version of DSM-V released.

MKN-10[edit | edit source]

Also known as ICD-10 ( International Statistical Classification of Diseases and Related Health Problems 10th revision).

In the current classification, the fifth is devoted to psychiatry V. chapters Mental disorders and behavioural disorders. It contains about 1000 categories, codes F00-F99, for viewing here. The long-traded division of disorders into psychoses disappears and neurosis.

F00−F09 organic mental disorders, including symptomatic ones
F10−F19 mental disorders and behavioral disorders caused by the effect of psychoactive substances
F20−F29 schizophrenia, schizophrenic disorders and delusional disorders
F30−F39 mood disorders
F40−F49 neurotic disorders, stress-induced disorders and somatoform disorders
F50−F59 behavioral syndromes associated with physiological disorders and somatic factors
F60−F69 personality disorders and behavioral disorders in adults
F70−F79 Mental retardation
F80−F89 disorders of psychological development
F90−F98 behavioral and emotional disorders in childhood (with onset usually in childhood and adolescence)
F99 non-specific mental disorder

Rules of the diagnostic process[edit | edit source]

The process is three-step:

  • first, specific symptoms (moods, etc.) are collected.);
  • they are grouped into specific syndromes;
  • subsequently, the presence of a certain disease is deduced.

A mental disorder (according to the APA) is a pattern of behaviour that is associated with unpleasant feelings or impairment of function in at least one important area of ​​life.
