What are the different mental behavioral disorders

In the following, diseases are described under "Mental and behavioral disorders", which according to ICD-10 can be assigned to this category (F00-F99). The ICD-10 is used for the international statistical classification of diseases and related health problems (International Statistical Classification of Diseases and Related Health Problems) and is recognized worldwide.

Mental and behavioral disorders

A behavioral disorder is a conspicuous behavior pattern that is inappropriate and ineffective for the situation.
Mental and behavioral disorders are multifactorial diseases that usually arise in childhood. They affect cognitive, social and motor levels. An affective behavior is also typical, which means brief and impulsive emotions such as anger, hatred or joy.

If those affected or the social environment suffer from the behavior, one speaks of a disorder. Frequently, however, those affected do not perceive their behavior as impairing. Noticeable behavior disorders are z. B. strong restlessness, aggression against people and animals, extreme fearfulness, uncontrolled outbursts of anger, screaming, concentration problems, obscene behavior, refusional attitudes or deliberate destruction of objects. Behavioral problems can be temporary, e.g. B. due to an acute stressful event, but also become a permanent problem and therefore in need of treatment.

According to ICD-10, mental and behavioral disorders can be divided into the following groups:

Organic, including symptomatic mental disorders (ICD-10: F00-F09)
These diseases are caused by a cerebral ("brain-affecting") disease, brain injury, or other damage that causes brain dysfunction. The brain can be directly affected (primary functional disorder) or secondarily as part of a systemic disease (several organs are affected).

Mental and behavioral disorders due to psychotropic substances (ICD-10: F10-F19)
The disorders or illnesses assigned to this group are caused by the use of one or more psychotropic substances such as alcohol, opioids, cocaine, cannabinoids, sedatives (tranquilizers) or hypnotics (sleeping pills).

Schizophrenia, schizotypal, and delusional disorders (ICD-10: F20-F29)
The most important clinical picture in this group is schizophrenia. Persistent delusional disorders and transient psychotic disorders are also included.

Affective disorders (ICD-10: F30-F39)
The disorders in this group manifest themselves in changes in mood or affectivity, which can either be attributed to depression or a mood high. The change in mood is usually accompanied by a change in the general level of activity. Triggers are often stressful events. The majority of these disorders are prone to relapse.

Neurotic, stress and somatoform disorders (ICD-10: F40-F48)
These include disorders such as phobias, anxiety disorders, obsessive-compulsive disorder, somatoform disorders, and dissociative disorders.

Behavioral problems with physical disorders and factors (ICD-10: F50-F59)
Typical clinical pictures of this group are among others. Eating disorders, inorganic sleep disorders, sexual dysfunction (without organic cause), psychological and behavioral disorders in the puerperium.

Personality and behavioral disorders (ICD-10: F60-F69)
The disturbances are usually long-lasting. They can be the result of social experiences in the early course of individual development, but also later in life. Significant deviations in perception, thinking and feeling can be observed compared to the majority of the population.

Intelligence disorder (ICD-10: F70-F79)
The diseases in this group are based on a disorder of psychological development. The mental abilities such as cognition, language, but also motor and social abilities are delayed or incompletely developed.

Developmental Disorders (ICD-10: F80-F89)
The disorders begin in infancy or childhood. They go hand in hand with a restriction in the development or delay of functions associated with the biological maturation of the central nervous system (CNS). The course is steady. Language, coordination of movement and school skills are often affected. Small deficits often remain in adulthood.

Behavioral and emotional disorders beginning in childhood and adolescence (ICD-10: F90-F98)
These include, for example, hyperkinetic disorders, disorders of social behavior, emotional disorders of childhood, tic disorders and other behavioral and emotional disorders that begin in childhood and adolescence.

Unspecified mental disorders (ICD-10: F99-F99)
Here psychotic disorders are listed without further details.
