Psychotic Features of Bipolar Disorder
Psychotic features are often present during the manic phase of bipolar I disorder. Aspects of psychosis may also manifest during extreme episodes of depression. They are also present in schizophrenia and schizoaffective disorder. These features include delusions (false ideas about what is taking place or who one is) and hallucinations (seeing or hearing things which aren't there).
Here is a brief but comprehensive definition of Catatonia and catatonic features - which may be present in bipolar disorder - schizoaffective disorder - or schizophrenia.
Delusions of Reference refers to the strongly held belief that random events, objects, behaviors of others, etc., have a particular and unusual significance to oneself.
Delusions are false beliefs that are firmly held. They are one aspect of the psychotic features of bipolar disorder, schizophrenia and schizoaffective disorder.

Psychosis is a loss of contact with reality, typically including delusions (false ideas about what is taking place or who one is) and hallucinations (seeing or hearing things which aren't there).
Family and linkage studies have provided some evidence for overlapping genetic susceptibility between bipolar disorder and schizophrenia. If shared genes are responsible for the psychotic manifestations of both disorders, these genes may result in clustering of psychotic symptoms in some bipolar disorder pedigrees.
Biometrical model fitting was applied to clinical data from twins to investigate whether operationally defined schizophrenic, schizoaffective, and manic syndromes share genetic risk factors.
