Schizophrenia Schizophrenia is a mental disorder that disables the brain and leaves a person with a sense of psychosis. A person diagnosed with this disorder may see or hear things that other people do not see. They may also think that if they are talking to someone, the other person is controlling their mind or planning to hurt them in some way. This will lead to the schizophrenic person withdrawing from any social interaction or becoming very agitated. There are many different genetic and environmental factors that contribute to the development of schizophrenia. Some environmental factors include exposure to certain viruses, stress in that person's life (parents of the person getting divorced, problems at school, etc.), prenatal malnutrition in pregnant women, and certain types of drug use in adolescents . These drugs, such as cannabis, methamphetamine, hashish, and marijuana, could be a very likely cause of schizophrenia in adolescents. Alcohol has also been considered a likely contributor to the disorder. Furthermore, the factors that contribute most to the development of this disorder are complications during pregnancy. This can include diabetes while the woman is pregnant, complications during the birth of the baby, unusual growth of the fetus, low birth weight, and birth before the baby is fully developed. A pregnant woman may react to an infection of the placenta, the fetus, or even the woman herself. Having this infection can trigger a certain toxic effect on the developing neurons in the child and will regulate neurodevelopmental processes such as those found in schizophrenia. A genetic factor in schizophrenia would be a gene on chromosome twenty-two called COMT (... middle of the paper ... we found very minimal changes in the person's brain cell traits. This could have occurred even before this person was born. The changes occurred they would connect with brain function, but you wouldn't be able to see the actual physical change until that person has reached puberty. During puberty, the brain will undergo major changes and, in some cases, could lead to very psychotic symptoms, leading so the person to the development of schizophrenia. There are several ways in which schizophrenia can develop in a person. There can be even more factors that contribute to the development of the disorder by researching everything they might discover, whether it is related to genes or the environment. It is still a disorder that confuses everyone in our society today.
