The schizophrenia is associated with an increased dopamine- dependent neuronal activity in the brain. The neuronal networks that transmit information by electrical signals from a nerve cell through
its axon and across synapses to postsynaptic receptors on other nerve cells seem to malfunction. Neurotransmitters that are implicated in schizophrenia are dopamine, norepinephrine, serotonin, glutamate, and gamma- aminobutyrc acid (GABA). The transmission of the signal across the synapse requires a complex series of biochemical events. In studies it shows that relatives of individuals that has schizophrenia are more prone to developing the disorder, it is also associated with individual that are associated with being a twins (Townsend, 2015). Schizophrenia is the most disabling psychotic disorder. Studies indicate that symptoms occur earlier in men then in women, and symptoms generally occur in late adolescent and early adulthood. Symptoms of disorder would usually occur before the age of 30. Clinical symptoms usually affect the individual and also the family because it is considered deteriorating disorder that requires a lot of patience from a family (Townsend, 2015). Individuals may have trouble functioning in school, work, and society. Schizophrenia impairs individuals to realize they are ill and need treatment. This sometimes the causes of why some people with this disorder become homeless, incarcerated, or have aggression and violence when communicating with individuals (Townsend, 2015).
