Cause Of Schizophrenia Essay

870 Words4 Pages

Is schizophrenia caused by socioeconomic status, genetics or chemical imbalance? Schizophrenia is a severe mental disorder, where the patient may suffer from psychoses where their thoughts and emotions are so impaired that contact is lost with external reality. Schizophrenia will cause severe changes in the way the person thinks, feels, and acts. This disease has yet to find a cure, but first, what is the cause of schizophrenia? Someone suffering from schizophrenia may have difficulty distinguishing between what is real and what is imaginary. A person with schizophrenia may be unresponsive, withdrawn, and have a problem expressing emotion in social situations. The cause of schizophrenia remains unclear, but there are some theories …show more content…

Scientists believe that people with schizophrenia have an imbalance of the two brain chemicals, also known as neurotransmitters, dopamine and serotonin. These neurotransmitters allow nerve cells in the brain to send signals and messages to each other, which cannot happen with excess amounts of the chemicals. The imbalance of these chemicals affects the way a person’s brain reacts to stimuli. This explains why a person with schizophrenia may be overwhelmed by sensory information that unaffected persons can handle. Research also shows that problems with the development of connections and pathways in the brain while in the womb may later lead to schizophrenia. An imbalance of the two neurotransmitters is thought to cause the symptoms of schizophrenia (MHA 3). The “dopamine hypothesis” has been the main theory regarding the cause of the symptoms of schizophrenia. It is known that only an excess amount of dopamine in the brain results in the symptoms. The dopamine hypothesis of schizophrenia generally states that the symptoms of schizophrenia, primarily the hallucinations, delusions, and psychosis is the result of too much dopamine active in the brain. As a result of this, the brain produces an over-stimulation of the cells and the symptoms. (DNALC

In some cases drug use is a trigger for the symptoms of schizophrenia and can lead to exacerbation of these symptoms. Marijuana in particular is now known to significantly worsen symptoms and well as cause signs of psychosis to appear at a much younger age (Foti et al., 2010). Those with schizophrenia are more likely to develop addictive behaviours than those without the disorder and this may be a result of irregular dopamine levels. Dopamine is an important part of the reward system and increased levels are produced as a result of many addictive drugs. Therefore, it is no surprise how those with schizophrenia are much more likely to exhibit addictive behaviour due to the abnormal levels of dopamine that may be present in the brain resulting from the differing chemical structure of the schizophrenic

There are many different biological speculations as to what causes schizophrenia, but one of the main reasons is that it “involves overactivity if dopamine transmission in the brain (Nevid et al., 431). This hyper-activity can then result in the hallucinations and the other symptoms associated with schizophrenia. Studies have shown though, that it is not necessarily an overage of dopamine in the brain, but rather the brain not being able to properly receive and respond to the dopamine that it receives (Nevid et al., 2018). Strictly, behavioral theorists would claim that people develop schizophrenia from defective learning of what is correct behavior and what is not correct behavior (Nevid et al., 2018). When I was researching and thinking about how behavioral theorists would explain schizophrenia, I was able to grasp how this perspective would explain schizophrenia by realizing that the voices and hallucinations in side the ill person’s head would be the encouraging aspect of the problem.
