- Hallucinations
- Delusions
- Disorganized thought patterns
- Disorganized speech
- Negative symptoms
- Reduced passion or interest
Delusional disorder
Delusional disorder is a mental illness and a type of psychotic disorder. Individuals are diagnosed with the delusional disorder if they are having one delusion for 30 days or more. Delusions are the strong beliefs of individuals and they remain stuck to that despite the strong evidence that is antagonistic to reality.
Moreover, delusion is a common symptom of schizophrenia but both delusional disorder and schizophrenia are different. Individuals with delusional disorder only experience delusions instead of hallucinations or any other common symptom of schizophrenia. However, there is also a possibility that hallucinations can occur but this is not as common as in schizophrenia.
Types of Delusions in Schizophrenia
Schizophrenia is a mental illness that results from the loss of connection with reality. Individuals remain in their self-created thoughts and are unable to differentiate their thoughts from reality. Among all the symptoms of schizophrenia, delusions are more common and are characterized as a false belief. Individuals battling with schizophrenia experience some delusions which are of the following types:
1. Persecutory delusions:
Persecutory delusions are the most common type of delusion in schizophrenia. Individuals with this delusion type think that they are in danger or have a threat to their lives. They more often take stress that someone is following them and they are harassed or get killed any time. Therefore, they consider every second person a spy or consider themselves a target of any conspiracy held by any government. Due to this delusion, they never feel relaxed and keep thinking about the ways that can help them save their life from unexpected threats.
2. Grandiose delusions
Grandiose delusion is a type of delusion in which people believe that they have some exceptional powers in them. They feel more important and think they have exceptional superpowers or knowledge that they can do anything and achieve their life goals. Moreover, they think that they are a famous leader, hero, or any other famous personality and people should admire them.
3. Referential delusions
Referential delusions involve the delusion that individuals think that any random event or scenario that happens in their life is for a specific purpose and carries a deep meaning. Moreover, they think that they have to focus on that event to get the idea. For example, if they hear any news on a radio or television then they think that it is a coded message that is directed specifically for them.
4. Erotomanic delusions
In this type of delusion, people believe that someone is madly in love with them. However, they do not find any evidence regarding this, still their belief remains the same. Among all other types of delusions, the erotomanic delusions are highly strong as the individuals think that the other person is giving them a strong vibe of love and concern or reciprocating their feelings when they are not.
5. Somatic delusions
Individuals with somatic delusion feel that they are suffering from any severe or end-stage medical illness. In reality, they are perfectly healthy and there is not any symptom of physical evidence that shows their illness. Moreover, they keep considering their health and seek medical attention from experts.
6. Nihilistic delusions:
Nihilistic delusions are characterized by the feelings of death. Individuals have the delusion that they are not alive and dead. Moreover, they also think that the world is going to end and everything will disappear soon. This type of delusion is highly dangerous as it leads to too intrusive or suicidal thoughts and the resulting negative or severe behavior.
