From Wikipedia (wondering if my Pdoc is right?):

Schizoaffective disorder is distinguished by*mood disorder-free psychosis*in the context of a long-term psychotic and mood disorder.[2]*Psychosis*must meet criterion A for*schizophrenia*which may include*delusions,*hallucinations,*disorganized speech, thinking or behavior*and*negative symptoms.[2]*Both delusions and hallucinations are classic symptoms of psychosis.[8]*Delusions are false beliefs which are strongly held despite evidence to the contrary.[8]*Beliefs should not be considered delusional if they are in keeping with cultural beliefs. Delusional beliefs may or may not reflect mood symptoms (for example, someone experiencing depression may or may not experience delusions of guilt). Hallucinations are disturbances in perception involving any of the five senses, although*auditory hallucinations*(or "hearing voices") are the most common.[8]*A lack of responsiveness or*negative symptoms*include a lack of spontaneous speech, reduced intensity of outward emotional expression,*avolition*(loss of motivation), and*anhedonia*or inability to experience pleasure.[8]*Negative symptoms can be more lasting and more debilitating than positive symptoms of psychosis.

Mood symptoms are of*mania,*hypomania,*mixed state*or*depression, and tend to be episodic rather than continuous. A*mixed episode*represents a combination of symptoms of mania and depression at the same time. Symptoms of mania include elevated or irritable mood, grandiosity (inflated self-esteem), agitation, risk-taking behavior, decreased need for sleep, poor concentration, rapid speech, and racing thoughts.[8]*Symptoms of depression include low mood, apathy, changes in appetite or weight, disturbances in sleep, changes in motor activity, fatigue, guilt or worthlessness, and suicidal thinking.
