Genetics and mental and mental illness .. Physical formations such as height, weight, skin color, hair color, eye color, nerve composition, activity rate of the glands



Genetics means biological transmission through genes from parents to children at the moment of conception. The most important influences on genetics are body formations such as height, weight, skin color, hair color, eye color, nerve composition, glandular activity rate, etc.
Most people know that mental illness is not contagious, but the most important concern is that the disease is transmitted to children by inheritance, which has been an important issue in medical research over the past few years. Genetic influence is found to be persistent in some psychiatric diseases such as schizophrenia, The role of heredity appears to be preparing the person for the mental illness, but this infection occurs only through the intervention of other factors directly affecting this genetically exposed person.
The closer the family connection to the casualty, the greater the likelihood of injury. However, the probability of injury to children is far below the risk of infection. This does not necessarily mean that children are infected. This is evidence that the infection is not only due to heredity, but also to the son's (or mother's) participation in the environment and living. The twins, who share the same genetic quality, even if they are separated from one another and from their families, and a sibling in two different families since the first weeks of their lives, are likely to have a high risk if the other twin has a psychiatric illness. This is one of the strongest signs of genetic influence.
The effect of heredity in mild mental illnesses and personality disorders will remain less apparent than others, although they have some effect on some personality traits of the human being. For example, the likelihood of a relative being affected is more likely to be caused by cohabitation than by the effect of genetic factors.
The doctor usually mentions an example of a disease that is highly susceptible to hereditary disease Huntington, s chorea, a neurological disease in which the patient experiences neurological and muscular disorders that appear in the body's movements, as if the patient is dancing, as well as multiple mental disorders. This disease affects only those who have inherited hereditary disease, where the probability of emergence after the transmission of genes or genetic factors from a parent is a high probability of up to 50 percent.
