Full Answer

Individuals with grandiose delusions feel an exaggerated sense of importance, explains the American Academy of Child and Adolescent Psychiatry. Somatic delusions cause healthy people to believe they have a terminal illness, and paranoid delusions cause people to believe others are against them.

Early-stage characteristics of psychotic behavior include anxiety, suspiciousness, depression, sleep changes and social withdrawal, states Healthline.com. Trouble concentrating and continuous abnormal beliefs and thoughts are additional signs of early stage psychosis. Characteristics of later-stage psychosis include suicidal actions and thoughts, trouble functioning, disorganized speech, hallucinations, and delusions.

Schizoaffective disorder is when an individual exhibits characteristics of both schizophrenia and a mood disorder, such as depression.
