The National Institute of Mental Health reports that approximately 1 percent of the U.S. population has schizophrenia, with men and women affected equally. As they report July 3 in the journal Cell Stem Cell, their experiments show that the loss of a particular gene alters the skeletons of developing brain cells, which in turn disrupts the orderly layers those cells would normally form. At first, researchers thought that the problem was solely caused by excesses of dopamine in the brain. Johns Hopkins researchers have begun to connect the dots between a schizophrenia-linked genetic variation and its effect on the developing brain. It's not known what causes schizophrenia, but researchers believe that a combination of genetics, brain chemistry and environment contributes to development of the disorder.Problems with certain naturally occurring brain chemicals, including neurotransmitters called dopamine and glutamate, may contribute to schizophrenia.

For example, the prefrontal cortex is connected to another brain area affected in schizophrenia called the basal ganglia. Dopamine is a neurotransmitter that influences our ability to think, plan, focus, and feel pleasure. These chemical messengers, known as neurotransmitters, are essential to all of the brain's functions. This region is known for producing dopamine and regulates coordinated movement, motivation and the reward pathway. Similar to the decreased connections between the prefrontal cortex and the basal ganglia, a February 2015 study report published in "European Psychiatry" found altered connectivity between parts of the limbic system and the prefrontal cortex in people with schizophrenia.

Improper function of the prefrontal cortex results in loss of these capabilities and the characteristic disordered thinking of schizophrenia. The most common structural abnormality involves the lateral brain ventricles. According to radiology professor Manzar Ashtari, scientists have studied adolescents with schizophrenia as well as adults, and they have come to believe that schizophrenia starts in one area of the brain and spreads as people age. However, studies have shown significant dysfunction in the prefrontal cortexes of people diagnosed with schizophrenia.

This suggests different parts of the autistic brain have difficulty working together to process complex information. Brains with schizophrenia also show neurochemical differences when compared with normal brains. (2) It was noticed that in brains affected with schizophrenia, far more neurotransmitters are released between neurons, which is what causes the symptoms. ... Rather than looking for genes that affect … The human brain is composed of two types of tissue: the nerve fibers of white matter, and the cell bodies of grey matter. “The dopamine hypothesis” posits that the hallucinations and delusions experienced in schizophrenia are caused by either too much dopamine being released or an extreme dopamine sensitivity in the brain. A July 2013 study report published in "Biological Psychiatry" noted that brain imaging studies demonstrate increased activity in the basal ganglia and decreased connectivity between this region and the prefrontal cortex in people with schizophrenia. Located directly behind the forehead, the prefrontal cortex oversees many aspects of our cognition, behavior, and personality.

Impaired function of the prefontal cortex in people with schizophrenia may be related to the excessive release of the brain chemical dopamine. Other structural changes include larger ventricles and basal nuclei.

While there is no cure, symptoms can often be controlled with medication, but it can take a while to find the proper drug and dosage that works for each person. The variety of symptoms seen with schizophrenia may be a result of how highly interconnected the brain is. The chemical messengers or neurotransmitters (primarily gamma-amino butyric acid or GABA) released by these interneurons are diminished in the brains of people with schizophrenia, suggesting that there is less inhibition of brain overload.
