In schizophrenia, sufferers may suffer from different delusions. UFOs from space, work for the secret service and voices that invite one to end the meaningless life: these are common delusions. But when does it come to a delusion and how delivered is this?
What is a delusion?
"You're crazy, " or "What you just fine again" are just two of many phrases that are meant to express that the other person obviously perceives a situation differently than you do. But the deviant perception of a fact does not automatically mean that Delusions are present: Only in delusion the reality is morbidly and uncorrectably misjudged - a change of attitude ("maybe my opinion is not right"), which is possible in the discussion between healthy people becomes impossible; the delusion is a rigid and contentwise false conviction.
Definition of delusions
Delusions are among the disturbances of thought and are often embedded in a complex delusion reality that opens up only to the patient. This delusion may exist in addition to the actual reality or completely dominate the thinking of the patient. In delusion, persons, memories, ideas and moods are misjudged and delusional perception often becomes life-determining.
For the person concerned, this reality is uncorrectably correct - he is not in a position to question his ideas critically. The result is that he is isolated in his delusion, which in turn supports the morbid self-relatedness that occurs in delusion. A delusion is often preceded by a mood of delusion in which the person concerned appears threatened by the world.
Schizophrenia: delusions and delusional system
The delusion leads to everyday occurrences being "reinterpreted". If this happens with events from earlier times, it's called Wahn Memories. Delusions, of which the work for a secret service is one of the best known, are embedded in a delusional system - the delusional work that is done here serves, inter alia, the explanation of all delusions (so-called explanatory delusion).
Common topics for delusions are:
- persecutory delusions
- Guilt and sinning thoughts
- a massive concentration on the own person (relationship delusion, "everything happens only because of me" and impairment delusion, "everything should harm me")
- Love and jealousy
Besides, there is the size and vice versa the petty or nullity delusion; Furthermore, the dermatological delusion, in which the affected person is convinced that animal pathogens have penetrated through his skin, and the impoverishment delusion.
Delusion in schizophrenia
Some delusions typically occur in certain diseases - schizophrenia, for example, relationship, impairment, persecution, dermatoscopy, and megalomania.
To get a comprehensive picture of the expression of the delusion, the attending physician uses the so-called psychopathological findings. The affected person is usually not in a position to perceive the delusions, to compare the course of his thought processes with the healthy phases of life and to name the sometimes very stressful changes.
When do delusions occur?
Although delusions also occur in brain tumors or a brain infection, after taking drugs or drugs, but these are rather rare causes. The delusions of jealousy in chronic alcohol addiction, or the delusional misjudgment of persons with dementia, as well as delusional depressions.
There are usually delusions that fit well with the depressive mood, such as impoverishment or insanity delusion, hypochondriacal delusion and petty or nullity delusion. Here, therefore, the underlying disease is the cause of the delusion.
Schizophrenia and its causes
Most commonly, however, are delusions in schizophrenia, one of the most common mental illnesses. The probability of someday developing schizophrenia is one percent worldwide.
The causes of a schizophrenic illness consist of a network of psychosocial and genetic-biological factors. Acute stress situations can lead to the onset of the disease if it is predisposed.
Dopamine plays a central role in the development of psychotic symptoms by flooding the emotional systems of the brain. Schizophrenics have more dopamine and dopamine receptors, which could be responsible for symptoms such as delusions, hallucinations and paranoia.
