What is delusion?

Delusion is defined as a fixed, false belief that conflicts with reality. Despite the evidence to the contrary, people in a state of delusion cannot give up these beliefs.of

Misunderstandings of events tend to reinforce delusions. Many delusions also involve some degree of paranoia. For example, one might argue that despite the evidence to the contrary, the government is controlling our every move through radio waves.

Delusions are usually part of mental disorders. They may occur at the same time as hallucinations, which involve perceiving something that does not really exist, such as hearing a sound or feeling a bug crawling on your skin.


The hallmark of delusion is an unshakable belief in something untrue, and usually, despite the evidence to the contrary, we continue to believe this delusion. Not all delusions are the same. Some may involve non-singular beliefs that theoretically may occur in real life. Others may be bizarre, fantastic or impossible.

The nature of the delusional symptoms may play a central role in the diagnosis. For example, delusions are characterized by non-singular delusions, usually involving misunderstandings of experience or perception. In schizophrenia, delusions may be bizarre rather than rooted in reality.

Types of delusions

There are several different types of delusions that are characteristic of the diagnosis of delusions. The type of obstacle is determined by the subject of the delusion experienced.of


In this type of delusion, the individual thinks that a person-usually of a higher social status-is in love with them. An example of this illusion is that someone believes that actresses love them and they communicate with them through secret gestures on TV shows.


In grand delusions, despite the lack of evidence, people still believe that they have extraordinary talents, fame, wealth, or power. An example of this illusion is someone who believes that God has given them the power to save the universe and every day they complete certain tasks that will help the earth move on.


People with persecuted delusions believe that they are being monitored, drugged, stalked, slandered, deceived, or abused in some way. An example might include someone who thinks that their boss can add a substance to the water dispenser to make employees work harder, thereby prescribing drugs.

With this illusion, individuals may think that their partner is unfaithful. For example, people with this illusion may think that every time they go to the toilet in public, their partner is meeting with their lover-they also think that they are talking to their lover through other people (such as a cashier in a grocery store). Send secret messages.


People with somatic delusions believe that they are experiencing physical sensations or physical dysfunction under the skin, or they have a general medical condition or defect. For example, people who think that there are parasites in their bodies may suffer from somatic delusions.

Mixed or unspecified

When delusions do not fall into a single category and no single theme dominates, delusions are considered “mixed.” When the delusion does not fall into a specific category or the type of delusion cannot be clearly determined, mental health professionals may refer to the disorder as “unspecified.”


Researchers are not sure what caused the delusional state. There seem to be multiple genetic, biological, psychological and environmental factors at work.

Psychosis seems to be inherited in the family, so researchers suspect that delusions are genetically related. For example, children born to parents with schizophrenia may be more prone to delusions.

Abnormalities in the brain may also play a role. An imbalance of neurotransmitters (chemical messengers in the brain) may increase the likelihood of delusions.

Trauma and stress can also trigger delusions. At the same time, people who tend to be isolated seem to be more likely to suffer from delusions.

Sometimes people will share delusions. This experience is most common among individuals who live together and have little contact with the outside world.

Related conditions

Delusions may be symptoms of mental health problems or brain diseases. Here are some situations that may involve delusions:

  • Transient psychotic disorder: People experience hallucinations, delusions, or speech confusion, which may be triggered by stressful events. The symptoms of this disease can last for a month or less.
  • Delusion: People experience “non-singular” type of delusions, and can usually act normally without significant impairment of function. It is estimated that only 0.2% of the population meets the criteria, and this disease is considered a relatively rare mental illness.
  • Dementia: Although estimates vary, approximately one-third of people with dementia may experience delusions. Often, these delusions are related to paranoia, such as thinking that family members or caregivers are stealing from them.
  • Mood disorders: Sometimes, people with mood disorders such as depression or bipolar disorder may experience delusions.
  • Parkinson’s disease: The prevalence varies greatly, but many patients with advanced Parkinson’s disease experience hallucinations and delusions.
  • Postpartum psychosis: Hormonal changes after childbirth may trigger postpartum psychosis in some women. Some studies have shown that it is also related to bipolar disorder.
  • Schizoaffective disorder: This disorder involves the symptoms of schizophrenia and emotional problems such as depression or mania.
  • Schizophrenia: This disease involves “positive symptoms” such as hallucinations or delusions. It also involves “negative symptoms” such as flat mood, decreased pleasure in daily life, difficulty in starting and maintaining activities, and decreased speech.
  • Schizophrenia: The symptoms of this disease are similar to schizophrenia, but the duration is less than six months.
  • Mental disorders caused by substances/drugs: Drug or alcohol intoxication or withdrawal may cause delusions in some people. Symptoms are usually short-lived and often disappear once the medication is cleared, but psychosis caused by amphetamine, cocaine, or PCP may last for several weeks.


If a person develops delusional symptoms, their doctor will first take a medical history and conduct a physical examination. Laboratory tests may also be ordered to rule out any physical illness that may cause symptoms.of

If there is no medical condition that caused the symptoms, the doctor may refer the individual to a psychiatrist for further evaluation. Mental health professionals may use various psychological assessments to learn more about the person’s symptoms.Then it can be diagnosed according to the diagnostic criteria in the diagnostic criteria Manual of Diagnosis and Statistics of Mental Disorders (DSM-5).


For anyone experiencing delusions, it is important to seek professional help. However, this can be particularly challenging because people who experience delusions usually don’t consider their beliefs to be a problem, because by definition, people who experience delusions believe that their experiences are facts. As a result, relatives who must bring the problem to the attention of healthcare professionals often receive attention.

In some cases, hospitalization is needed to help the delusional person stabilize – especially when they pose a danger to themselves or others.

The treatment of delusions usually involves a combination of medication and therapy.


Medications may include:of

  • Typical or first-generation antipsychotics: These drugs are used to block dopamine receptors in the brain. Dopamine is a neurotransmitter and is thought to be involved in the development of delusions.
  • Atypical antipsychotics: These drugs are used to block dopamine and serotonin receptors in the brain. This leads to different side effects from the first-generation antipsychotics.
  • Sedatives: Sometimes these drugs are used to solve anxiety, agitation, or sleep problems that are common in patients with delusional disorders.
  • Antidepressants: If delusional patients have emotional problems, these drugs can be used to treat depression.


Therapies may include cognitive behavioral therapy (CBT),Help individuals learn to recognize and change unhelpful thoughts and behaviors. Family therapy is usually also part of the treatment. Through treatment, family members can learn how to support people who are experiencing delusions.


The management environment can also help people with delusions. For example, if someone thinks that the government is monitoring them through TV, then that person would better avoid watching TV. Or, if a person thinks they will be followed when they enter the community alone, it is better to have someone with them when they are out.

Very good sentence

Most diseases involving delusions cannot be cured, but can be treated. In fact, some people can lead healthy, productive lives with few symptoms. But some people do work hard, maintain healthy relationships, and participate in activities related to daily life. Ask a healthcare professional to provide help and support for you or your loved ones.
