Although many human disorders can be explained by simple Mendelian hereditary patterns, others are more complex in their nature. Multifactorial diseases are influenced by a range of factors, specifically an individual’s genetics and environment. One example of a complex disease is schizophrenia, a mental affliction that is caused by a chemical imbalance in or the irregular structure of the brain. Schizophrenia is characterized by hallucinations or delusions and inhibits individuals from rationalizing, controlling emotions, communicating, or making independent choices. Thus schizophrenia is a complex and chronic disorder that affects individuals uniquely, and is influenced by both genetic and environmental stimuli (“What”).
Schizophrenia affects the cognition processes and emotional responses of people which can be seen when they find it difficult to identify the line between real and imagery and show distress. It is significant to know that schizophrenia should not be confused with split personality. Some common symptoms of schizophrenia are hallucination, thought and movement disorder, delusion, lack of emotions and senses, and problems with memory. There are many theories about the causes of schizophrenia but it is still not clear about the exact cause of this brain disorder. The most notable factors that explain schizophrenia are brain structure and genetics.
