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.
Prodromal stage
This is the first stage of schizophrenia. It occurs before noticeable psychotic symptoms appear. During this stage, a person undergoes behavioral and cognitive changes that can, in time, progress to psychosis.
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.
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.
The main psychological triggers of schizophrenia are stressful life events, such as: bereavement. losing your job or home. divorce.
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 fundamental symptoms, which are virtually present through all the course of the disorder (7), are also known as the famous Bleuler's four A's: Alogia, Autism, Ambivalence, and Affect blunting (8). Delusion is regarded as one of the accessory symptoms because it is episodic in the course of schizophrenia.
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.
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).
People with anxiety disorders are at increased risk for developing schizophrenia. This may be because anxiety and schizophrenia share common features, such as problems with sleep, concentration, and decision-making problems.
At least one of the symptoms must be delusions, hallucinations, or disorganized speech. In determining a diagnosis, the doctor may order additional tests, including an MRI scan or blood test.
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.
Autism and schizophrenia are separate neurodevelopmental disorders that share a number of interpersonal and cognitive deficits. The symptoms of autism first appear during early life while schizophrenic symptoms do not typically appear until adolescence at the earliest.
Word salad is a severe form of formal thought disorder, a feature in schizophrenia that causes a disturbance in how thoughts are organized and expressed. In word salad, words and phrases may be loosely associated with one another but don't actually form a coherent thought.
For example, people may not dress according to the weather, (i.e., they may wear a heavy coat in the middle of summer), they may wear odd or inappropriate makeup, they may shout at people for no apparent reason, or they may mutter to themselves continuously, etc.
Background: People with schizophrenia often exhibit deficits in empathy, which plays a major role in social cognition and interpersonal relationship.
Visual. 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.”
In sum, in this study we found that schizophrenia patients make a higher number of false memories when episodes lack affective information, especially for new plausible information.
If one parent has the condition, it raises your chances of developing schizophrenia by about 13 percent. If your identical twin has the illness, you have a roughly 50 percent chance of developing schizophrenia. If both of your parents have schizophrenia, you have a 40 percent likelihood of developing the illness.
