Mental health can be observed within the framework of subjective well-being, perceived selfeffectiveness and autonomy with which every person can achieve their intellectual and emotional capacity. Mental disorders are characterized by abnormalities in knowledge, emotions, or mood, whereby an individual can not function normally because disturbances hinder the creation of rational cognition. They are the public health problem of the whole world, and year after year there may be an increase in the number of people affected. They can be divided and distinguished by severity of symptoms, duration, and functional impairment. Some of the most famous are anxiety, depression, psychosis, and mood disorder. The stigma of patients with mental illness is a public secret whereby society responds to the most common prejudices affecting patients who, because of that perception, do not want to report and seek help. Inadequate hospitalization and treatment of patients with mental disorders should be understood as the last act that most commonly concerned patients decide after they realize that they can not provide the necessary help. It is a widespread use of different powers through the process of forced hospitalization, which clearly has to establish access standards in order to protect the basic human rights of the patient Croatia has a matter of forced hospitalization and forced treatment set out in the Act on the Protection of Persons with Mental Disabilities, which entered into force in 2015 as a replacement for the law of the 1990s and its 2002 amendments. At the EU level, the most important items on this issue are defined in the European Convention on Human Rights and Fundamental Freedoms. So many countries have aligned their national legislation with this Convention. A person who meets the appropriate criteria can be hospitalized to make the psychiatrist and medical staff diagnosed and apply the appropriate treatment. When compulsory hospitalization and treatment occurs, the ethical question is how far this act is justified and whether the autonomy of the patient is distorted by such decisions. Suicide and violence in patients undergoing forced hospitalization is most commonly associated with the history of previous diseases, genetic predispositions and their disorders. The most commonly used preventive methods are the psycho-educational program, the crisis card and the intervention program.
