What is schizoaffective, and how does it differ, if at all, from schizophrenia?
Schizoaffective is essentially Schizophrenia+ a Mood disorder like bipolar or depression.
DSM-5 Critereon A for Schizoaffective Disorder
"An uninterrupted period of illness during which there is a major mood episode (major depressive or manic) concurrent with Criterion A of schizophrenia."
Critereon A for Schizophrenia
"A. Two (or more) of the following, each present for a significant portion of time during a
1 -month period (or less if successfully treated). At least one of these must be (1 ), (2), or (3):
3. Disorganized speech (e.g., frequent derailment or incoherence).
4. Grossly disorganized or catatonic behavior.
5. Negative symptoms (i.e., diminished emotional expression or avolition)."
The DSM-5 is the Diagnostic and Statistical Manual of Mental Disorders 5th Edition. The go-to manual for diagnosing a person to have a mental disability.https://docs.google.com/file/d/0BwD-YtZFWfxMbWs2UC1WdWJzZTQ/edit?pli=1
And I seen a Khan Academy video on schizoaffective disorder which says that the prognosis is usually better than schizophrenia, although people with this illness can recover at any level of success between schizophrenia (which is horribly low) and the mood disorder (which is variably high). So they are pretty similar, schizophrenia and schizoaffective disorder. But differ mainly on moods.
