How are schizophrenics brains different?
Individuals with schizophrenia have up to 25% less volume of gray matter in their brains, especially in the temporal and frontal lobes (known to be important for coordination of thinking and judgment). Patients demonstrating the worst brain tissue losses also tend to show the worst symptoms.
What in the brain causes schizophrenia?
Research suggests schizophrenia may be caused by a change in the level of 2 neurotransmitters: dopamine and serotonin. Some studies indicate an imbalance between the 2 may be the basis of the problem. Others have found a change in the body’s sensitivity to the neurotransmitters is part of the cause of schizophrenia.

The loss was greater for men (15.9) than for women (13.6). Life expectancy was greatly reduced in patients with schizophrenia, at 64.7 years (59.9 for men and 67.6 for women).

I fully embraced this concept as I strove to find ways to manage my newly acquired insight into being psychotic while also being incarcerated.
Does schizophrenia reduce intelligence?
We have recently shown the distribution of ID in a large cohort of schizophrenia patients. Consistent with previous studies, approximately 30% of schizophrenia patients had a decline of less than 10 points, i.e., normal intellectual performance. In contrast, approximately 70% of patients showed deterioration of IQ.
How does a schizophrenic brain look like?
The white matter conducts nerve signals across the brain and throughout the central nervous system to allow your body and brain to do anything. Nemoianu says that a decrease in gray matter is the “most commonly observed change,” in the schizophrenic brain.

What does schizophrenia do to the brain?
Schizophrenia is a disease that affects the brain. It alters brain chemistry and brain form to produce the different behavior in those afflicted with the problem. It appears that these alterations change the inherent I-function in each individual. Loss of important functions associated with this piece of the greater nervous system box is found in these people.
