SCHIZOPHRENIA SPECTRUM AND OTHER PSYCHOTIC DISORDERS (psychosis is the
major/main part of all these disorders) (Schizotypal P.D.) *duration is important. Know for test*
Psychosis - lost of contact with reality
1. Delusional Disorder - least severe. The person has one or more delusions with the
duration of one month or more. No impairment and behavior is not odd; the person is
okay aside from the delusion.
○ Delusion: a fixed false belief. What makes this different from a bad idea? The
person with delusion is not open to any evidence that their idea/belief is wrong.
○ A delusion is something that no matter how much evidence is presented, the
person will not change their mind.
○ Something that is SO OBVIOUSLY FALSE no matter your beliefs.
○ The delusions have more to do with the person themselves
Types of Delusions
i. Erotomanic delusion - the person is convinced that someone else is in
love with them who probably isn’t. Can cause stalking
ii. Grandiose delusions - convinced that they have some amazing talent or
insight or great discovery
iii. Jealous delusions - convinced that their spouse is being unfaithful
iv. Persecutory delusion - central theme that they are being cheated on,
spied on, followed, poisoned, drugged, harassed, that some people are
out to get them in a very particular way.
v. Somatic delusion - a delusion about their bodily functions. Belief that a
terrible thing is happening with their body
● My hand has been replaced by an elephant

something that is not there. Most commonly auditory hallucinations. The voice is
typically no their own. Can also be visual and somatic hallucinations.
i. The hallucinations are usually consistent with the delusions
ii. Delusions altered to fit hallucinations
○ Disorganized speech - what is being said does not make sense. Loose
association. Putting together things that don’t belong
○ Grossly disorganized or catatonic behavior
i. Disorganized behavior - can’t figure out how to open a notebook. Can’t
walk out of a room when that is what you want to do
ii. Catatonic behavior - the person may be in a stupor (not responding to
