Most people with schizophrenia are non-violent and usually, do not pose a danger to other people. (Mental Health America, 2013)

They may come up with a person that they really love, hate, or have a different opinion about. In their mind, they may have no connection with reality. They live in their own world. People with schizophrenia are seen with different moods. The disease affects individuals with different backgrounds and every person unique. Studies have shown that the younger the patient the more severe the effects. The condition worsens with age. In the beginning, people appear slightly eccentric, reclusive, irate, and emotionally upset. Their appearance becomes untidy, say weird things, and life becomes indifferent. (Wilkenson, 2014) People with schizophrenia require lifelong treatment. Getting symptoms under control will help improve quality of life. (Mayo Clinic Healthy Living, 1998-2018) The cause of schizophrenia is unclear. Many theories include heredity, abnormal brain chemistry, viral infections, and immune disorders to name a few. Scientist agree that some disorders run in families and that people may inherit or develop the disease over time. It may appear dormant in the body until the body undergoes hormonal or physical changes. These changes usually occur during puberty or stressful situations. (Mental Health America, 2013) There can be individuals who have it, but no one else in their family has it. There also may be people with multiple family members that have been diagnosed with schizophrenia but do not develop it themselves. Scientists understand that many different genes can increase the risk but are unable to identify a specific gene that causes the disorder by itself. (National Institute of Mental Health, 2016)

No one symptom indicates a diagnosis of schizophrenia. Hallucinations and delusions are some of the most common symptoms. (Torrey, 2013)

The American Psychiatric Association describes 3 categories of symptoms: positive, negative, and cognitive. Positive symptoms are described as existent or present to only the person. They appear out of touch with reality. They include delusions, hallucinations, strange or distorted, larger than life ideas, behaviors or perceptions.
