The exact causes of schizophrenia are unknown. 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.
Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized speech, and reflect an impaired ability to function. The effect can be disabling. In most people with schizophrenia, symptoms generally start in the mid- to late 20s, though it can start later, up to the mid-30s.
As is the case with many major neuropsychiatric illnesses, the typical age of onset for schizophrenia is in late adolescence or early twenties, with a slightly later onset in females.
Highly stressful or life-changing events may sometimes trigger schizophrenia. These can include: being abused or harassed. losing someone close to you.

The symptoms of schizophrenia are usually classified into: positive symptoms – any change in behaviour or thoughts, such as hallucinations or delusions. negative symptoms – where people appear to withdraw from the world around then, take no interest in everyday social interactions, and often appear emotionless and flat.
Residual Schizophrenia
This specific type is characterized by when an individual doesn't display positive symptoms of paranoid schizophrenia (hallucinations, delusional thinking), although they still have the negative symptoms or more mild schizophrenia symptoms (no expression of emotions, strange speech).
Symptoms of Borderline Schizophrenia
Level of functioning in work, interpersonal connection, or self-care is impaired by the symptoms for a significant portion of time. Change in functioning is significant compared to previous level of functioning. Continuous signs of the disturbance for a six-month period.
Unfortunately, most people with schizophrenia are unaware that their symptoms are warning signs of a mental disorder. Their lives may be unraveling, yet they may believe that their experiences are normal. Or they may feel that they're blessed or cursed with special insights that others can't see.

People with schizophrenia suffer a wide range of social cognitive deficits, including abnormalities in eye gaze perception. For instance, patients have shown an increased bias to misjudge averted gaze as being directed toward them.
Personality disorders such as antisocial, borderline, histrionic, narcissistic, avoidant, dependent and obsessive-compulsive types have been detected in one third to one half of schizophrenia patients (Nielsen, Hewitt & Habke, 1997; Solano & Chavez, 2000).
Peculiar, eccentric or unusual thinking, beliefs or mannerisms. Suspicious or paranoid thoughts and constant doubts about the loyalty of others. Belief in special powers, such as mental telepathy or superstitions. Unusual perceptions, such as sensing an absent person's presence or having illusions.
Schizoaffective disorder.
People with schizoaffective disorder have the same symptoms as people with schizophrenia. But they also have episodes of depression and times when they feel extremely happy or have lots of energy (mania). For more information, see the topics Depression and Bipolar Disorder.
This illness can cause severe symptoms such as hallucinations, delusions, strange behaviors, and suicidal thoughts. It is a lifelong illness and one of the top reasons people are on disability. Despite the serious and life-threatening symptoms, about half of the people who receive this diagnosis do not get treatment.
Schizophrenia treatment includes medication, therapy, social and family support, and the use of social services. Treatment must be ongoing, as this is a chronic illness without a cure. When schizophrenia is treated and managed over the long-term, most people can live normal, productive, and fulfilling lives.
People who have psychotic episodes are often totally unaware their behaviour is in any way strange or that their delusions or hallucinations are not real. They may recognise delusional or bizarre behaviour in others, but lack the self-awareness to recognise it in themselves.
Someone might see lights, objects, people, or patterns. Often it's loved ones or friends who are no longer alive. They may also have trouble with depth perception and distance.
Most commonly though, people diagnosed with schizophrenia will hear multiple voices that are male, nasty, repetitive, commanding, and interactive, where the person can ask the voice a question and get some kind of answer.”
Pareidolia is the perception of faces in ambiguous visual stimuli, such as clouds, rock formations, or flocks of birds, and is thus a type of visual illusion (35). Pareidolia occurs when an indistinct and often randomly formed stimulus is interpreted as being definite and meaningful.
