The view emerging from this work is that schizophrenia is fundamentally a disorder of disrupted neural connectivity, the sources of which appear to be genetic and environmental risk factors influencing brain development both pre natally and during adolescence.
The Default Mode Network
When weâre just hanging out — the dishes are done, weâve finished our homework, or we’ve completed a tough project at work — our thoughts are free to roam. This âdefault modeâ allows us time to daydream, reflect, and plan. It helps us to process our thoughts and memories. Scientists call this the default mode network.

There are two large and interesting independent, studies of people with a prodromal syndrome that, is high likely to lead to schizophrenia – one in Scotland- and another in Melbourne, Australia . Both these studies have performed very parallel investigations.
Schizophrenia Brain Changes
In some conditions, such as multiple sclerosis, areas of damage are visible on brain scans. This is not the case with schizophrenia. It is not currently possible to diagnose schizophrenia using brain imaging alone.
Early Symptoms of Schizophrenia
Because early treatment is thought to be most effective for schizophrenia, researchers are continually looking for ways to detect it before symptoms fully develop.
Tests and Scans
There are several commonly used scales that are used in the diagnostic process for schizophrenia.
Before and After
If a healthcare professional decides that a medical scan will help in the diagnostic process, then the patient should be prepared for what is required before and after the possible tests.
Frequently Asked Questions
Schizophrenia is both a mental health condition and a chronic brain disorder. Abnormalities in both the structures of the brain and brain chemistry have been noted in people with schizophrenia.
A Word From Verywell
As more research emerges supporting the classification of schizophrenia as a chronic brain condition, in addition to a mental health condition, the opportunities for new and possibly more effective treatments increase.
What is the name of the area of the brain that is affected by schizophrenia?
The variety of symptoms seen with schizophrenia may be a result of how highly interconnected the brain is. For example, the prefrontal cortex is connected to another brain area affected in schizophrenia called the basal ganglia.
What are the findings of a brain scan for schizophrenia?
Doctors looking at brain scans. The reduced level of connections among these brain areas and alterations in brain chemicals are key findings that may explain the symptoms and abnormal behavior seen in people with schizophrenia. Evidence also points to reduced brain volume, however.

Why is dopamine important in the brain?
Dopamine gets a lot of attention in brain research because it’s been linked to addiction. It also plays a role in other psychiatric and movement disorders, like Parkinson’s disease. In schizophrenia, dopamine is tied to hallucinations and delusions. That’s because brain areas that "run" on dopamine may become overactive.

If you have schizophrenia, your default mode network seems to be in overdrive. You may not be able to pay attention or remember information in this mode, one study shows. Outlook. Researchers are working on new medications for the disorder. At least one tackles the glutamate factor.
Does schizophrenia have gray matter?
Doctors also believe the brain loses tissue over time. And imaging tools, like PET scans and MRIs, show that people who have schizophrenia have less “gray matter” -- the part of the brain that contains nerve cells -- over time. This research is helping efforts to develop better treatments for people who have this condition.
