Lönnqvist et al. (2009) studied the premorbid personality traits Neuroticism, Extraversion, and Disinhibition as predictors for later schizophrenia and other psychoses, showing a connection between these psychopathologies and high Neuroticism and low Extraversion.
On the five-factor personality scales, SZ subjects showed higher levels of neuroticism, and lower levels of openness, agreeableness, extraversion, and conscientiousness than control subjects. Higher scores on openness and lower scores on neuroticism distinguished schizophrenia spectrum PD from SZ.
Many researchers consider schizotypal personality disorder to be one of the schizophrenia spectrum disorders, which also includes brief psychotic disorder, schizophreniform disorder, schizoaffective disorder and delusional disorder.
Men and women are equally likely to get this brain disorder, but guys tend to get it slightly earlier. On average, men are diagnosed in their late teens to early 20s. Women tend to get diagnosed in their late 20s to early 30s.
Schizotypal personality disorder can easily be confused with schizophrenia, a severe mental illness in which people lose contact with reality (psychosis).
Sometimes, people confuse dissociative identity disorder, formerly known as multiple personality disorder, and schizophrenia.
Personality disorders (PD) with positive and negative psychotic-like features are assumed to be closely related to the schizophrenia spectrum; these are paranoid PD, schizoid PD, and schizotypal PD (SPD).
The link between schizophrenia and intelligence
People with high IQ scores are less likely to have schizophrenia than the general population.
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).
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.
If someone is psychotic (or has what doctors call psychosis), their mind is losing its grip on reality. A psychopath is someone who isn't able to feel for others and may act in reckless and antisocial ways. Psychosis is often a symptom of another condition, while psychopathy is a personality trait.
Most people make a good recovery and have their symptoms disappear. An increased understanding of psychosis has led to new interventions to help young people recover. People with psychosis can be treated in their community and if hospitalization is required, it is usually only for a brief period.
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.
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.
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.
Borderline schizophrenia is a term that is used to describe the occurrence of both BPD and schizophrenia. However, it is not an established diagnosis. BPD and schizophrenia are separate conditions that can occur together. They also share many similarities.
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. Symptoms may include: Delusions.
In this early phase of schizophrenia, you may seem eccentric, unmotivated, emotionless, and reclusive to others. You may start to isolate yourself, begin neglecting your appearance, say peculiar things, and show a general indifference to life.
BPD is a very different diagnosis than schizophrenia, though the two can co-exist. While BPD is characterized by a pattern of instability in interpersonal relationships; schizophrenia is characterized by a range of cognitive, behavioral, and emotional dysfunctions.
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.
Of the different types of schizophrenia, residual schizophrenia is the mildest, characterized by specific residual schizophrenia symptoms.
Never tell your loved one that their symptoms are “not true,” “not real,” “imaginary,” or all in their head. Aim to be nonjudgmental.
Some personality types that are prone to mental health conditions include isolated introverts, overachievers, dramatists, day dreamers, worry warts, and perfectionists. People with these personalities are at risk of anxiety, depression, panic attacks, and other mental disorders.
