How to treat a person with mental problems?

First, the intelligence level is obviously lower than the average level. The evaluation of children's intelligence level can be carried out through observation, that is, according to children's activities, language and behavior to evaluate children's intelligence. For example, some mentally retarded children smile when they meet, drool when they open their mouths, are not enthusiastic and don't know what to ask, but according to this judgment, there is still a lack of quantitative analysis. At present, standardized children's intelligence test is adopted internationally to evaluate children's intelligence level. For example, children aged 0-3 choose gesell Development Assessment Scale, children aged two and a half who are six and a half choose to revise Wechsler Preschool Intelligence Scale, children aged six to twelve choose Children Intelligence Screening Scale, and children aged six and a half who are sixteen and a half can choose to revise Wechsler School-age Intelligence Scale.

Second, there are hard defects in social function adaptation. Adaptive behavior is a person's ability to deal with daily life and survive in social environment. Adaptation defect refers to the defect of individual function corresponding to his age and educational level, such as social skills, social responsibility, speech, daily cooking, independence and self-ability, and social behavior ability can be observed and collected by doctors. For example, visit families and schools for evaluation, and you can also use the adaptive behavior scale for evaluation.

Third, this phenomenon occurs in the developmental period, that is, before 18 years old. If 18 years old later, mental retardation occurs, it is called dementia.
