In the literature it has been suggested that some delusions can have an adaptive function by acting as defence mechanisms, protecting people from suffering or from unpleasant truths. Most of the cases discussed in the literature refer to psychological adaptiveness rather than biological adaptiveness.
Psychotic symptoms may be explained as a natural defense mechanism or protective response to stressful environments.
Do not reason, argue, or challenge the delusion. Attempting to disprove the delusion is not helpful and will create mistrust. Assure the person that they are safe and no harm will come. Do not leave the person alone – use openness and honesty at all times.
Most theorists agree on the first step, that delusions arise in the context of a delusional mood, an emotionally aroused state that makes the person hyperalert to threat. After that, some assume perception goes awry—something misheard or misperceived giving rise to increasing emotional upheaval and misinterpretation.
Delusional disorder is a type of psychotic disorder. Its main symptom is the presence of one or more delusions. A delusion is an unshakable belief in something that's untrue. The belief isn't a part of the person's culture or subculture, and almost everyone else knows this belief to be false.
Environmental/psychological: Evidence suggests that stress can trigger delusional disorder. Alcohol and drug abuse also might contribute to it. People who tend to be isolated, such as immigrants or those with poor sight and hearing, appear to be more likely to have delusional disorder.
Types of delusions include persecutory, erotomanic , grandiose , jealous, somatic, and mixed/unspecific.
People can have delusional disorder and anxiety at the same time. Anxiety creates feelings of intense worry. Delusional disorder symptoms revolve around false beliefs or inaccurate interpretations of real-life situations. These interpretations persist even when the person encounters evidence that disproves the belief.
Bizarre delusions: the person believes in something that is physically impossible. Delusional jealousy: the person believes their partner is being unfaithful, even when that's impossible. Misidentification syndrome: the person believes someone they know has been replaced by an imposter who looks identical to that ...
Three specific phases are defined: the delusional, double-awareness, and nondelusional phases.
Avoid Challenging Delusions
Simply telling your loved one that they are wrong is not helpful. Delusions feel very real to the person experiencing them, and by simply dismissing them or challenging them you can make him or her retreat and withdraw.
Every anxiety disorder has its own fears, and often these fears can become delusions when they start to control your thoughts.
Can a person know that they are experiencing a delusion? Created with Sketch. A person can be aware that they are gripped by a belief that others do not endorse and may even actively attempt to disprove, but the belief feels so overwhelmingly true that they cannot shake it, despite evidence to the contrary.
People with experiences of psychosis report high rates of trauma [1] and are often diagnosed with trauma-related conditions such as post-traumatic stress disorder (PTSD) [2].
A psychotic breakdown is any nervous breakdown that triggers symptoms of psychosis, which refers to losing touch with reality. Psychosis is more often associated with very serious mental illnesses like schizophrenia, but anyone can experience these symptoms if stress becomes overwhelming, triggering a breakdown.
There are studies that show the experience of trauma in childhood, whether or not it develops into PTSD, is a risk factor for schizophrenia and psychosis later in life. An extensive review of 27,000 studies has definitively confirmed that trauma puts people at risk for psychotic conditions and symptoms.
Delusional Disorder in DSM-5
Hence, delusional disorder is characterized by at least 1 month of delusions without other psychotic symptoms. However, hallucinations might be present, but are not prominent and in any case are related to the delusional theme only. DSM-5 does not require that delusions must be nonbizarre.
Persecutory delusion
This is the most common form of delusional disorder. In this form, the affected person fears they are being stalked, spied upon, obstructed, poisoned, conspired against or harassed by other individuals or an organization.
Poor insight into irrationality of one's delusional belief(s) Believing that others are attempting to harm the person (persecutory type) Belief that others are in love with the person (erotomanic type) Belief that one has great talents or a history of important achievements (grandiose type)
Delusions may be present in any of the following mental disorders: (1) Psychotic disorders, or disorders in which the affected person has a diminished or distorted sense of reality and cannot distinguish the real from the unreal, including schizophrenia, schizoaffective disorder, delusional disorder, schizophreniform ...
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.
Major depression is a serious mood disorder that causes a low mood, hopelessness, fatigue, and apathy, but in some cases it can also cause psychosis. Psychotic symptoms include delusions, hallucinations, and disordered thinking and speech.
Age mean age of onset is about 40 years, but the range is from 18 years to 90 years. The persecutory and jealous type of delusion is more common in males, while the erotomanic variety is more common in females.
Some delusions can be very frightening and can make you feel threatened or unsafe. For example, you might feel that something or someone is trying to control, harm or kill you (even when you have no reason to believe this). These ideas are sometimes called paranoid delusions.
