Disability occurs in schizophrenia, and some studies have shown that schizophrenia accounts for about 70% of the total number of all patients with mental disability, a relatively large value. Patients in a state of psychiatric disability are significantly disconnected from society, living in their own inner world, with hyperactive instincts, increased appetite and sexual desire, and no sense of self-esteem or shame, similar to a state of dementia. Krepilin, a German psychiatrist, named schizophrenia as early-onset dementia. In the disabled state, patients with schizophrenia show a lack of attention, no motivation to do things, indifferent emotional reactions, no corresponding emotional reactions to the birth and death of loved ones, inability to work and study normally, inability to care for the elderly and children, and more pronounced intellectual impairment, and many people divorce because they cannot work normally. Family members abandon the patient because of the disease or push him into society, resulting in the patient wandering the streets. For patients with mental disabilities, they should never leave their families and society, despite the fact that the hope of cure is relatively slim, and should take the responsibility of their families and society to assist them with formal treatment and rehabilitation training, striving to minimize the damage of the disease to individuals, families and society.
