According to the CIF's classification of mental functions, psychosocial deficiency is defined as a problem in an individual's mental functions, which can include one or more limitations in the capacities of consciousness, learning, social interaction, temperament, energy and impulse, bonding, personality, memory, concentration, language, and perception. The effects of a mental condition on a person's life are frequently catastrophic, and they can only be controlled and conquered with the help of multiprofessional personnel as well as appropriate family and psychosocial support. The markings that the rupture of a normal state of health for the transition into a diagnosed mental disease frame, on the other hand, bring with them a historical background of losses, disappointments, and fragilities that can be stigmatising and exclusionary. Individuals with chronic and persistent mental illnesses, such as schizophrenia, bipolar disorder, and severe depression, have functional and cognitive impairments that limit their capacity to execute tasks and perform well. The promotion of the Brazilian Inclusion Law to people with severe mental disorders, which recognises them as people with psychosocial disabilities, provides an opportunity for people with mental disorders to have their fundamental rights and guarantees, as well as equality of access and participation, which promotes the process of inclusion and psychosocial rehabilitation for the strengthening of autonomy, quality of life, and community bonds.
