Schizophrenia is a brain disorder that affects the way a person acts, thinks, and sees the world. People with schizophrenia have an altered perception of reality, often a significant loss of contact with reality
A brain scan cannot detect schizophrenia, although many people with schizophrenia do have abnormal brain scans. The brain damage is not apparent until the disease has already progressed far enough to show clear signs of schizophrenia.
You usually cannot diagnose schizophrenia from a simple brain scan. However, long-term damage to the brain from schizophrenia can sometimes be assessed by a MRI scan.
Schizophrenia has no effect on brain weight.
Typically, the temporal lobe and limbic system are involved in schizophrenia. Lesions, malformations, or simply dysfunction in dopaminergic neurons of these areas of the brain can result in the positive and negative symptoms of schizophrenia. Since excess dopaminergic activity is indicative of schizophrenia, antipsychotic drugs that block dopamine receptors are the usual treatment for this illness.
Biological factors such as genetics, brain chemistry, and neurological conditions can contribute to abnormal behavior. For example, imbalances in neurotransmitters like serotonin or dopamine can lead to conditions like depression or schizophrenia. Additionally, genetic predispositions or abnormalities in brain structure can also play a role in the development of abnormal behaviors.
The dopamine hypothesis of schizophrenia suggests that an overactive dopamine system in the brain contributes to the symptoms of schizophrenia. Specifically, an excess of dopamine activity in certain areas of the brain is believed to be a factor in the development of psychosis in schizophrenia.
A schizophrenic brain may show structural and functional abnormalities, such as decreased brain volume in certain areas and altered connectivity between brain regions. Additionally, dopamine dysregulation is often observed in individuals with schizophrenia. However, brain imaging studies have not identified a specific pattern or characteristic that can definitively diagnose schizophrenia.
Abnormal behavior has been linked to a damaged or malfunctioning brain through neuroimaging studies that show differences in brain structure or function in individuals with certain mental health conditions. For example, abnormalities in specific brain regions or neurotransmitter systems have been associated with conditions like schizophrenia, depression, and anxiety disorders. These findings suggest that changes in brain functioning may contribute to the development of abnormal behaviors.

Sleep is good for everyone, but especially people with mental health disorders. There is some scientific research that good sleep (eight to ten hours of quality sleep) can help bring chemicals in the brain back to normal levels. Since many researchers think that schizophrenia is caused by abnormal levels of dopamine (a chemical in the brain), sleep probably helps with the symptoms of schizophrenia.
Schizophrenia mainly affects the brain.
Evidence suggests that schizophrenia is a physical disorder of the brain.
