Schizophrenia involves a range of problems with thinking (cognition), behavior and emotions. Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized speech, and reflect an impaired ability to function.
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.
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.
The difference between a paranoid schizophrenic and a paranoid personality is the lack of hallucinations and delusions in the paranoid personality. In other words, they are suspicious about the motives of others, but they do not hear voices or have visual hallucinations found in schizophrenia.
Symptoms may include: Delusions. These are false beliefs that are not based in reality. For example, you think that you're being harmed or harassed; certain gestures or comments are directed at you; you have exceptional ability or fame; another person is in love with you; or a major catastrophe is about to occur.
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 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.
In the first, prodromal phase, friends and family might notice strange behavior. You might want to be alone much of the time and may start to talk only about certain topics, such as religion, the government, or a particular public figure. This phase can last from weeks to years.
Schizophrenia can only be diagnosed by a medical doctor or mental health professional. A doctor may use tests like MRIs, CT scans or blood tests to check for physical causes for your symptoms.
Tests Used to Diagnose Schizophrenia
Tests that scan and make pictures of the body and brain, like magnetic resonance imaging (MRI) or computed tomography (CT scan), might also help rule out other problems, like a brain tumor.
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.
You could have: 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.
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).
Although schizophrenia most commonly presents early in life, at least 20% of patients have onset after the age of 40 years. Some have proposed that schizophrenia with onset between the ages of 40 and 60 years is a distinct subtype of schizophrenia, late-onset schizophrenia (LOS)(1).
Anti-NMDAR encephalitis.
This autoimmune disease causes swelling in the brain. That swelling can lead to behaviors and thought patterns that look like schizophrenia, such as paranoia and hallucinations. But most people with anti-NMDAR encephalitis have other symptoms such as seizures and suddenly passing out.
Simple schizophrenia
Negative symptoms (such as slow movement, poor memory, lack of concentration and poor hygiene) are most prominent early and worsen, while positive symptoms (such as hallucinations, delusions, disorganised thinking) are rarely experienced.
While there is no one blood test to detect schizophrenia, regular blood testing can provide important information about a person's schizophrenia treatment and overall well-being.
Psychotic disorders include schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, delusional disorder, shared psychotic disorder, substance-induced psychotic disorder, and paraphrenia.
Bipolar is one of the most frequently misdiagnosed mental health issues. Somewhere between 1.4 and 6.4 percent of people worldwide are affected by bipolar disorder. However, it's hard to say which number is more accurate due to the frequency of wrongful diagnosis.
