An example of a delusion would be when someone thinks that there is no such thing as gravity.

Delusions often seem very real to the person experiencing them.

They are not aware that their beliefs are irrational or unreasonable.

People with delusions might have multiple delusions about different topics.

Treatment for delusions usually involves medications and psychotherapy.

Hallucinations are usually seen as a cause of delusions.

Anything that increases the serotonin levels in the brain can make a person more prone to hallucinations.

Some drugs that have hallucinogenic effects, like LSD or peyote use can result in hallucinations.

Symptoms of delusions vary depending on the type of delusion being experienced.

Delusions can be classified as mood-congruent or mood-incongruent.

Mood-congruent delusions are based in feelings that are consistent with a person's emotions.

Mood-incongruent delusions are often bizarre, unlikely thoughts not related to a person's emotional state.

Treatment focuses on the symptoms that accompany the delusion.

In some cases, if the delusions cause distress or interfere with a person's ability to function in daily life, medication may be prescribed to manage these symptoms.

In other cases, psychotherapy is an option.

The type of therapy depends on the nature of the delusions and the person's mental health needs.
