Schizophrenia: Why it happens, Causes, Symptoms and its Effects

The word Schizophrenia is derived from the Greek words skhizo meaning split and phren meaning mind. This word was discovered in 1908 by  the Swiss psychiatrist Eugen Bleuler.


Schizophrenia is a condition of mental disorder characterized by a disturbance in thinking emotions. It affects the ability of a person to think clearly, behave properly, feel. Schizophrenia generally leads to social withdrawal.

For example: A person who is hungry will eat while a schizophrenic will have completely opposite thoughts at a same time he will think he is hungry and should eat and at a same time will think how to eat? I am so full.

A schizophrenic gets this completely opposite thoughts at a same time. This is the reason schizophrenia leads to social withdrawal.


It is the most common disease of all psychiatrist disorders. It has been estimated that almost 50% of all mental hospital beds are occupied by schizophrenic’s. Schizophrenia is equally prevalent in both men and women. The peak ages of onset are 15-25 years for men and 25-35 years for women.

In this article we learned about Schizophrenia, its causes, symptoms and types. We learned that family relationships or social circle can also lead to Schizophrenia. A person having stress and undergoing depression due to any reasons have very high probability of getting Schizophrenia. A more loved or pampered person also have high chance of getting Schizophrenia. So, i would like to conclude this article by asking everyone of you to behave nicely with all . We should not be the reason of somebody’s depression. And parents should also maintain a balance of love by not completely neglecting their child as i have seen some parents neglecting their child because they are mentally unfit In such case the disease becomes more severe and not completely pampering child because these are also causes of Schizophrenia. Consanguinity should also be avoided as it also one of the cause of Schizophrenia so consanguineous marriage should be avoided as their children have high chances of getting schizophrenia. We  may not be capable of treating Schizophrenic’s but our nice behaviour can surely make it less painful for them.
