Schizoaffective disorder symptoms may vary from person to person. People with the condition experience psychotic symptoms, such as hallucinations or delusions, as well as symptoms of a mood disorder — either bipolar type (episodes of mania and sometimes depression) or depressive type (episodes of depression). Although the development and course of schizoaffective disorder may vary, defining features include a major mood episode (depressed or manic mood) and at least a two-week period of psychotic symptoms when a major mood episode is not present. Signs and symptoms of schizoaffective disorder depend on the type — bipolar or depressive type — and may include, among others: 
Delusions — having false, fixed beliefs, despite evidence to the contrary
Hallucinations, such as hearing voices or seeing things that aren't there
Impaired communication and speech, such as being incoherent
Bizarre or unusual behavior
Symptoms of depression, such as feeling empty, sad or worthless
Periods of manic mood, with an increase in energy and a decreased need for sleep over several days, and behaviors that are out of character
Impaired occupational, academic and social functioning
Problems with managing personal care, including cleanliness and physical appearance
