Document Summary
50-70% of those with scz experience delusions, hallucinations, or both. 25% of those with scz experience these symptoms. Delusions: fixed belief that is a misrepresentation of reality. Heard to change even when presented with conflicting information. Persecutory: belief that he/she is going to be harmed, harassed, etc by an individual, organization, etc. Grandiose: belief that he/she possesses exceptional abilities, wealth, or fame. Bizarre delusions: clearly implausible and not understandable to same culture peers; do(cid:374)"t deri(cid:448)e fro(cid:373) ordi(cid:374)ar(cid:455) life e(cid:454)perie(cid:374)(cid:272)es (cid:894)through i(cid:374)sertio(cid:374) or withdrawal) Hallucination: sensory experience in the absence of external stimulus. In scz, the person believes the perception are real and they occur regularly. But can involve all senses (gustory= tasting something when not eating; tactile= having skin sensations when not being touched) Loose association: switching rapidly from one topic to another. Tangentiality: answers to questions may be only somewhat or completely unrelated. Incoherent (word salad): so severely disorganized that nearly incomprehensible.
