Schizophrenia is a condition that is not well known and there are misconceptions in the community about the condition. The editors also depict methods There is no clear link between neurotransmitter changes and the pathophysiology of schizophrenia; however, studies have shown that subcortical dopamine dysfunction is the key mechanism.

Negative symptoms of schizophrenia comprise a group of severe symptoms contributing to high disease burden and poor long-term prognosis. Instead, an emerging concept is that the DA system may be relatively normal, but is subjected to a dysregulation as a consequence of the abnormal control Schizophrenia, a severe brain disorder that involves hallucinations, disordered thinking and deficiencies in cognition, has been studied for decades in order to determine the early events that lead to this neurological disorder. However, on the functional level, deficits are evident in symptom dimensions, a subtle loss of volumes in specific brain regions, and in the activation pattern of neuronal networks. 1998, Strakowski et al.
