Schizophrenia is a psychotic disorder in which the affected person exhibits unusual perceptions, odd thoughts and disturbed emotions (Comer & Comer, 2018). Theorists explain this disorder in four major areas: the biological model, the psychological model, sociocultural model and the developmental psychopathology model. I consider the biological model as the one with the best description of this disorder as its argument is grounded on genetic and brain activity research (Comer & Comer, 2018). This model has had the most research done and has received the model support, which is a way of approving it as one of the best. Nevertheless, schizophrenia symptoms can be classified from the neurological impact they cause, such as hallucinations. The biological model focuses on the genetic connection between family members and onset on schizophrenia, this model also looks into neurons. Over the past four decades theorists and researchers of this model developed dopamine hypothesis, which is when certain neurons in the brain are firing too often (Comer & Comer, 2018). However, with the continuation of learning more about the brain and its function this has also went under more research. The biological model changes often, because we are still learning and growing with more funding and research available with new technology. However, this is the only model that correlates to the symptoms a person is experiencing on a neurological level rather than an external level.
