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.
Prodromal stage
It occurs before noticeable psychotic symptoms appear. During this stage, a person undergoes behavioral and cognitive changes that can, in time, progress to psychosis. The early stage of schizophrenia usually involves non-specific symptoms that also occur in other mental illnesses, such as depression.
The schizotypal personality is characterized by social anxiety, magical thinking, unusual perceptual experiences, eccentric behavior, a lack of close friends, atypical speech patterns, and suspicions bordering on paranoia. These personality traits that, taken together, resemble the symptoms of schizophrenia.
Early signs and symptoms
Schizophrenia signs and symptoms in children and teenagers are similar to those in adults, but the condition may be more difficult to recognize in this age group. Early signs and symptoms may include problems with thinking, behavior and emotions. Thinking: Problems with thinking and reasoning.
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.
Although schizophrenia can occur at any age, the average age of onset tends to be in the late teens to the early 20s for men, and the late 20s to early 30s for women.
Functional deficits such as emotional flattening, social withdrawal, and a lack of motivation and pleasure are usually prominent. The most commonly reported psychotic features are auditory hallucinations and delusions.
Experts aren't sure what exactly triggers the first episode or the early warning signs. But many things can lead to psychosis: Genetics. Several specific genes and a family history of psychosis may make it more likely for you to develop it.
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.
Onset is most often during late adolescence and the twenties, and onset tends to happen earlier among men than among women. Schizophrenia is frequently associated with significant distress and impairment in personal, family, social, educational, occupational, and other important areas of life.
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.
Symptoms tend to start in your late teens, 20s, or early to mid 30s. Men may be more likely to get their first symptoms or their first bout of psychosis earlier than women do. It's rare for someone to start showing symptoms as a child or when they're over 45 years old.
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.
An MRI scan—in which magnetic fields and sound waves are used to create two- or three-dimensional images—may provide a good view of the structure of the brain and rule out schizophrenia by detecting abnormalities that may be causing schizophrenia-like symptoms.
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 have trouble inferring other people's mental states. Eye-gaze direction is a ubiquitous social cue that we use to direct attention and infer what other people are thinking, what their intentions are.
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.
These changes happen gradually, typically in three phases: early, acute, and recovery. The onset of first episode psychosis typically presents when an individual is between the ages of 18-25, however, may present between the ages of 15-40. It is uncommon for first episode psychosis to present in childhood.
Of the different types of schizophrenia, residual schizophrenia is the mildest, characterized by specific residual schizophrenia symptoms.
The truth is that while schizophrenia is influenced by genetics, it isn't directly inherited.
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).
Pseudoneurotic schizophrenia was the term coined by Hoch and Polatin in the 1940s to describe patients who presented with “neurotic” facade, which concealed thought, emotional and behavioral impairment of regulation, integration, and stemmed from “psychotic” process [1].
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.
The link between schizophrenia and intelligence
People with high IQ scores are less likely to have schizophrenia than the general population.
