Each of ours possesses a flaw of one kind or the other. But our brain is adaptive enough to work around these flaws - at least most of the time. When the flaws are incorrectable and impassable, we usually classify the flaw as a psychological disorder. These disorders are also classified in terms of there variety and severity. Schizophrenia is on the more severe end of the spectrum.
Schizophrenia is a disorder that usually occurs during a severe and extreme moment in ones life.
It happens when ones brain is taken to the extreme in difficulties and stress. When it occurs, it devastates the victim of it as well as the family and friends of the victim. Schizophrenia is a disease that affects the perception of the person and distroys his ego. A schizophrenic tries to isolate himself from the world because he thinks it is trying to get him. It also makes the victim fantasize and imagine, to take his thoughts to extremes that are irrational to a normal, thinking human being.
