What are schizophrenia false beliefs called?

Schizophrenia is a chronic mental health disorder that affects how a person thinks, feels, and behaves. People with schizophrenia often experience hallucinations, delusions, disorganized thinking and speech, and impaired cognitive functioning. Delusions are one of the most common symptoms of schizophrenia. Delusions are fixed, false beliefs that are firmly held even when there is evidence to the contrary. There are several different types of delusions that people with schizophrenia may experience.

Types of Schizophrenia Delusions

Some of the most common types of delusions seen in schizophrenia include:

Persecutory delusions – Believing that others, or the government, are out to harm or punish you in some way. For example, believing that the CIA is following you or plotting against you.
Referential delusions – Believing that certain gestures, comments, song lyrics, newspaper articles, etc. have double meanings and are specifically about you. For example, believing that the television anchor is sending you secret messages.
Grandiose delusions – Believing that you have some great unrecognized talent or insight, or that you have made some important discovery. For example, believing you have solved an important mathematical equation that scientists everywhere have been working on.

Erotomanic delusions – Falsely believing that someone famous or of higher status is in love with you. For example, believing that a famous singer is communicating their love for you through their song lyrics.
Somatic delusions – Believing that you have an undiagnosed medical condition or physical defect. For example, believing that parasites are crawling under your skin.
Delusional jealousy – Believing that a spouse or partner is being unfaithful without any real evidence. This delusion often leads to accusations of infidelity.

Delusions of guilt – Believing that you have done something terribly wrong or committed some unforgivable sin, even though you have no evidence of this.
Nihilistic delusions – Believing that a major catastrophe will occur, such as the end of the world.

In addition to these types of delusions, people with schizophrenia may also have delusional thoughts about things like their identity, reality, and control over themselves or others. For example, someone may believe they are Jesus Christ or that aliens are controlling their thoughts and actions.

Causes of Delusions

Researchers are still working to understand the exact causes of delusions in schizophrenia. However, some key factors believed to contribute to delusion development include:

Biological factors – Changes in brain chemistry and structure may make someone more prone to experiencing psychosis and delusions.
Stress – High levels of stress may trigger delusion onset or make symptoms worse.

Social factors – Feeling isolated from others or having impaired social cognition may impact delusions.
Reasoning biases – People with schizophrenia often display reasoning biases like “jumping to conclusions” that can facilitate delusions.
Altered perceptions – Delusions may arise in an attempt to make sense of distorted perceptions during psychosis.

Genetics – Schizophrenia has a genetic component, so relatives of people with schizophrenia are more likely to have delusional disorders themselves.

Treating Delusions

Delusions can be very disruptive, distressing, and even dangerous for people with schizophrenia. Treatment focuses on reducing the frequency and intensity of delusions to improve quality of life. Common treatment approaches include:

Antipsychotic medications – These medications help balance brain chemistry and reduce psychotic symptoms like delusions. They are considered first-line treatment.

Psychotherapy – Talk therapy can help people identify delusions and develop coping strategies. Cognitive behavioral therapy is often used.
Social skills training – Improving social cognition and communication skills may minimize delusions.
Family therapy – Educating family members about delusions and involving them in treatment may increase support.

Assertive community treatment – Programs providing outpatient care, rehabilitation, and community support resources can help manage delusions.

Creating a comprehensive treatment plan tailored to the individual is key. Treatment is typically more effective when multiple approaches are used together.

Coping with Delusional Thoughts

In addition to professional treatment, people can use self-help strategies to cope with delusional thinking:

Keep a log of delusional thoughts and share it with your mental health provider.
Avoid drugs and alcohol, which can make delusions worse.
Distract yourself with activities you enjoy when you notice delusional thoughts arising.

Exercise regularly to reduce stress and improve mood.
Get enough sleep, as fatigue exacerbates symptoms.
Join a support group to realize you’re not alone.

Listen to loved ones when they tell you a belief seems unrealistic.
Avoid making major life decisions when delusions are active.

Learning to recognize delusional thinking and having healthy coping strategies in place can help minimize the impact of delusions on quality of life.

When Delusions Become Dangerous

While most delusions are not dangerous, some delusional beliefs result in risky or violent behavior that threatens the safety of the person with schizophrenia or others. Delusions that often lead to dangerous behavior include:

Persecutory delusions – Believing you need to defend yourself from a perceived attacker.
Delusions of jealousy – Resulting in violence against a perceived unfaithful partner.

Delusions of guilt or sin – Prompting unneeded and excessive confessing or atonement.
Grandiose delusions – Engaging in risky activities due to feeling invincible.
Somatic delusions – Causing self-inflicted harm or injuries in an attempt to get rid of perceived infestations or defects.

Nihilistic delusions – Potentially leading to suicidal behavior or putting others at risk in preparation for the believed impending catastrophe.

When dangerous delusions arise, hospitalization may be needed to protect the safety of the individual and others while the delusions are stabilized with medication and other intensive treatments.

Supporting a Loved One with Delusions

When a family member or friend is experiencing delusions, it can be difficult to know how to respond. Here are some tips for supporting a loved one with delusional thinking:

Avoid directly contradicting or arguing about the delusion, which can worsen symptoms. Instead, listen compassionately and suggest they talk to their mental health provider.
Express empathy for how frightening and distressing delusions can be.
Encourage adherence to prescribed medication and therapy.

Assist your loved one in identifying reality-testing strategies.
Provide reassurance that you are there to support them.
Set healthy boundaries if delusions lead to accusations or unsafe behavior.

Take care of your own wellbeing as well.
Educate yourself about schizophrenia and delusions.
Enlist outside support if needed, such as family therapy or support groups.

Being patient, compassionate, and non-judgmental can help your loved one feel understood and supported as they manage troubling delusional thoughts.

Delusions in Other Mental Illnesses

While delusions are a hallmark of schizophrenia, they can also occur in other mental disorders. Some examples include:

Bipolar disorder – Delusions may arise during severe manic episodes or psychotic depression.

Major depressive disorder – Delusions are possible during severe psychotic depression.
Schizoaffective disorder – This condition involves symptoms of schizophrenia and a mood disorder, so delusions are common.
Delusional disorder – This condition is defined by persistent non-bizarre delusions not caused by another psychotic disorder.

Brief psychotic disorder – Short-term delusions brought on by extreme stress are possible.
Substance-induced psychotic disorder – Intoxication from drugs or alcohol withdrawal can prompt delusional thinking.
Dementia – Late-stage dementia can result in delusional thinking.

While the nature and themes of delusions may vary based on the underlying cause, many similar treatment principles apply across disorders. Prescribing antipsychotic medication and psychotherapy to help cope with and minimize delusional thoughts is typically the first line of treatment in most cases.

Conclusion

In summary, delusions are false fixed beliefs that are held despite contradictory evidence. They are a core symptom of schizophrenia, but can occur in other mental disorders as well. The most common delusion types experienced in schizophrenia include persecutory, referential, grandiose, erotomanic, somatic, and delusions of guilt or jealousy. Delusions likely arise due to a combination of biological, psychological, and social factors.

Delusional thinking in schizophrenia can often be improved through medications like antipsychotics, psychotherapy approaches such as CBT, and rehabilitation programs. While most delusions are not dangerous, some can lead to risky behavior, requiring emergency hospitalization. Supporting a loved one with delusions requires empathy, compassion, and patience.

With proper treatment and support, the disruptive effects of delusions can be minimized. This allows people with schizophrenia to gain control over their delusional thinking and focus on recovery and living life to the fullest despite their diagnosis.
