Mental and Physical Infantilism The word "infantilism" comes from the Latin word "infantia", which means "infancy" or "child". Mental infantilism and physical infantilism are two different concepts associated with different aspects of human development. Mental infantilism refers to the immaturity of the individual, expressed in a lack of independence, inability to adapt to changing conditions and low emotional maturity. People suffering from mental infantilism may exhibit behavior characteristic of children: whims, disobedience, dependence on other people, inability to make independent decisions and take responsibility. Physical infantilism refers to a delay in physical development, which can lead to delays in height, weight and development muscles and organs. Mental infantilism can be associated with various mental disorders, such as mental retardation, autism, attention deficit hyperactivity disorder (ADHD), Down syndrome, bipolar disorder, etc. Some personality disorders, such as histronic personality disorder and narcissistic personality disorder, may also present with symptoms of mental infantilism. Physical infantilism may be caused by genetic disorders such as achondroplasia, cystic fibrosis and Turner syndrome, nutritional deficiencies such as protein, vitamin or mineral deficiencies, as well as diseases of the thyroid gland, digestive system and other chronic diseases. It is necessary to distinguish between the concepts of infantilism and infantilism. Infantilism is a medical condition caused by various causes, while infantilism describes behavior or personality characteristics that are associated with childhood, but are not appropriate for the age of an adult. Infantilism and infantilism Infantilism and infantilism both refer to a condition or behavior that is associated with childhood or immaturity. Infantilism generally refers to a medical condition in which an adult retains mental and physical characteristics typical of early childhood. This can be caused by genetic factors, head injuries, infectious diseases, abnormal brain development, and other reasons. People suffering from infantilism often require constant assistance and care, and may also experience problems with communication and social adaptation. Infantilism, on the other hand, describes behavior or characteristics that are characteristic of children, but are not age-appropriate for adults. For example, a person who constantly demands attention, cannot make decisions for themselves, or cannot control their emotions may be considered childish. Infantility can be caused by various factors, such as poor parenting, low self-esteem, anxiety or depression. It can lead to social problems such as lack of respect from others, problems in relationships and difficulties at work. In general, infantilism is a medical condition caused by various reasons, while infantilism describes behavior or personality characteristics that are associated with childhood but do not correspond to adult age. Regression and infantilism In psychoanalysis, the term "regression" usually refers to the reverse movement of mental processes into earlier stages of personality development. Thus, regression can manifest itself in a person's behavior and thinking as a return to more primitive, childish forms of behavior and reactions that are characteristic of earlier stages of life. Infantilism, in turn, is a condition when a person retains or resumes mental and physical characteristics , characteristic of a child or infant. Thus, we can say that infantilism is one of the manifestations of regression in a person’s mental life.
