Research suggests a combination of physical, genetic, psychological and environmental factors can make a person more likely to develop the condition. Some people may be prone to schizophrenia, and a stressful or emotional life event might trigger a psychotic episode.
Schizophrenia isn't caused by just one genetic variation, but a complex interplay of genetics and environmental influences. Heredity does play a strong role—your likelihood of developing schizophrenia is more than six times higher if you have a close relative, such as a parent or sibling, with the disorder.

Criteria to diagnose schizophrenia
Delusions. Disorganized speech. Disorganized or catatonic behavior. Negative symptoms (emotional flatness, apathy, lack of speech)
Emerging evidence has demonstrated that stress and other environmental factors may contribute to the development of schizophrenia. Although genes do play a role in the disease, the genetic concordance rate of schizophrenia is approximately 50% — even in identical twins.
Stressful life events
Highly stressful or life-changing events may sometimes trigger schizophrenia. These can include: being abused or harassed. losing someone close to you.
Although there is no proven way to prevent schizophrenia, scientists are looking for ways to make it less likely. Schizophrenia is a complex illness that may partly involve your genes. But events in your life may also play a role. The condition can sometimes run in families.
Drugs do not directly lead to or cause schizophrenia. However, studies have found that drug abuse increases the odds of developing schizophrenia or other related illnesses. Specific drugs like cocaine, cannabis, LSD, or amphetamines can trigger symptoms of schizophrenia in those more susceptible to the condition.
Schizophrenia is a mental illness that affects about 1% of the population. It is characterized by hallucinations, delusions, and disordered thinking and can be debilitating. There is no known cause of schizophrenia, but researchers have identified several risk factors. One of these risk factors is anxiety.
Research suggests that schizophrenia occurs due to a combination of genetic and environmental factors, which can cause abnormal development in the brain. In people with these risk factors, severely stressful life events, trauma, abuse, or neglect may trigger the condition.
Past studies have reported that offspring of affected mothers have a higher risk of schizophrenia than the offspring of affected fathers; however, other studies found no such maternal effect [Gottesman and Shields, 1976].
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 not entirely preventable but various protective factors — such as social support, mental health interventions, and avoiding substance use — may help to reduce your risk of developing the condition. Risk factors cannot determine for sure whether or not someone will develop schizophrenia.
What is the life expectancy for people with schizophrenia? People with schizophrenia generally live about 15 to 20 years less than those without the condition.
Eat More: Salmon and Other Fatty Fish
A growing amount of research says that omega-3 fatty acids can prevent and ease the symptoms of schizophrenia and slow the disease's progress. Salmon and mackerel are great sources of those acids.
Anxiety and affective symptoms are prominent features of schizophrenia which are often present in the prodromal phase of the illness and preceding psychotic relapses. A number of studies suggest that genetic risk for the disorder may be associated with increased anxiety long before the onset of psychotic symptoms.
Schizophrenia usually involves delusions (false beliefs), hallucinations (seeing or hearing things that don't exist), unusual physical behavior, and disorganized thinking and speech. It is common for people with schizophrenia to have paranoid thoughts or hear voices.
Anxiety symptoms can occur in up to 65 % of patients with schizophrenia, and may reach the threshold for diagnosis of various comorbid anxiety disorders, including obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD).
Some researchers believe that problems with brain development may be partly responsible for schizophrenia. Others believe that inflammation in the brain may damage cells that are used for thinking and perception. Many other things could also play a role, including: Exposure to viruses before birth.
Studying anger is important for schizophrenia because this disease is often associated with angry and hostile behavior (Volavka, 1999). Externalized anger in patients can lead to an increase in violent behavior (Brennan et al., 2000) and influence the prognostic process (Fassino et al., 2009).
There are now several lines of evidence suggesting that patients with schizophrenia may consume nicotine to self-medicate negative symptoms and – perhaps even more so – cognitive deficits as well as associated neurophysiological abnormalities.
Borderline schizophrenia is held to be a valid entity that should be included in the DSM-III. It is a chronic illness that may be associated with many other symptoms but is best characterized by perceptual-cognitive abnormalities. It has a familial distribution and a genetic relationship with schizophrenia.
Residual schizophrenia is the mildest form of schizophrenia characteristic when positive symptoms of paranoid schizophrenia (hallucinations, delusional thinking) are not actively displayed in a patient although they will still be displaying negative symptoms (no expression of emotions, strange speech).
Early Warning Signs of Schizophrenia
One is that people with the disorder often don't realize they're ill, so they're unlikely to go to a doctor for help. Another issue is that many of the changes leading up to schizophrenia, called the prodrome, can mirror other normal life changes.
