Schizophrenia is associated with changes in the structure and functioning of a number of key brain systems, including prefrontal and medial temporal lobe regions involved in working memory and declarative memory, respectively.
Schizophrenia has been described as the “worst disease” to afflict mankind. It causes psychosis, which is an abnormal state of mind marked by hyperarousal, overactivation of brain circuits, and emotional distress. An untreated episode of psychosis can result in structural brain damage due to neurotoxicity.
Schizophrenia is a complex brain disorder. It often runs in families and can cause troubling symptoms. It's caused by a chemical imbalance and other changes in the brain. Symptoms include hearing voices, feeling that people are out to get you, and having false beliefs that are not based in reality.
Schizophrenia is a chronic progressive disorder that has at its origin structural brain changes in both white and gray matter. It is likely that these changes begin prior to the onset of clinical symptoms in cortical regions, particularly those concerned with language processing.
Most people with schizophrenia are not violent. Overall, people with schizophrenia are more likely than those without the illness to be harmed by others. For people with schizophrenia, the risk of self-harm and of violence to others is greatest when the illness is untreated.
People with schizophrenia generally live about 15 to 20 years less than those without the condition. Schizophrenia is a complex disease. There are many ways it can result in serious complications.
Paranoid schizophrenia
It may develop later in life than other forms. Symptoms include hallucinations and/or delusions, but your speech and emotions may not be affected.
Results: In patients with schizophrenia, MR imaging shows a smaller total brain volume and enlarged ventricles. Specific subcortical regions are affected, with reduced hippocampal and thalamic volumes, and an increase in the volume of the globus pallidus.
The Brain In Schizophrenia
The fluid-filled spaces (the ventricles) in the interior of the temporal lobes are often enlarged and the temporal lobe tissue diminished. The greater the observed changes the greater the severity of the person's thought disorder and his or her auditory hallucinations.

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 brains of people with schizophrenia appear to be more sensitive to dopamine. In other words, dopamine makes the brain overactive. It can lead to symptoms like hallucinations and delusions.
Highly stressful or life-changing events may sometimes trigger schizophrenia. These can include: being abused or harassed. losing someone close to you.
The new study found that, when it comes to grey matter volume, this repairing effect over time actually makes the brains of schizophrenic patients grow to be more like the brains of people without the disease – which could help us to come up with new ways to develop treatments for the condition.
Schizophrenia does not typically get better as you get older. The symptoms of schizophrenia may become worse over time, or they may remain the same for some people. Schizophrenia is a chronic illness that can be managed with medication and therapy, but it does not typically go away as you get older.
Left untreated, schizophrenia can result in severe problems that affect every area of life. Complications that schizophrenia may cause or be associated with include: Suicide, suicide attempts and thoughts of suicide. Anxiety disorders and obsessive-compulsive disorder (OCD)
Most people with schizophrenia make a recovery, although many will experience the occasional return of symptoms (relapses). Support and treatment can help you to manage your condition and the impact it has on your life.
Having schizophrenia could affect your ability to drive. If you've had or currently suffer from a medical condition or disability that may affect your driving you must tell the Driver & Vehicle Agency (DVA).
The research literature shows that schizophrenia has neuroanatomical correlates that can be seen at group level by studying MR images. Structural MRI cannot currently be used to identify schizophrenia at the level of the individual.
Schizophrenia affects approximately 24 million people or 1 in 300 people (0.32%) worldwide. This rate is 1 in 222 people (0.45%) among adults (2). It is not as common as many other mental disorders.
There aren't any diagnostic tests for schizophrenia-spectrum conditions. But healthcare providers will likely run tests to rule out other conditions before diagnosing schizophrenia. The most likely types of tests include: Imaging tests.
In most people with schizophrenia, symptoms generally start in the mid- to late 20s, though it can start later, up to the mid-30s. Schizophrenia is considered early onset when it starts before the age of 18. Onset of schizophrenia in children younger than age 13 is extremely rare.
Schizophrenia is a chronic, severe mental disorder that affects the way a person thinks, acts, expresses emotions, perceives reality, and relates to others. Though schizophrenia isn't as common as other major mental illnesses, it can be the most chronic and disabling.
Hallucinations: Seeing or hearing things that aren't there. Delusions: Mistaken but firmly held beliefs that are easy to prove wrong, like thinking you have superpowers, are a famous person, or people are out to get you. Disorganized speech: Using words and sentences that don't make sense to others.
