You are describing symptoms of schizo-affective disorder. Here are the diagnotic criteria from the DSM-IV-TR ("diagnotic and statistical manual of mental disorder, fourth edition, text revision"
DSM-IV-TR criteria
The following are the revised criteria for a diagnosis of schizoaffective disorder from the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR):
A. Two (or more) of the following symptoms are present for the majority of a one-month period (or a shorter period of time if symptoms got better with treatment):
delusions
hallucinations
disorganized speech (e.g., frequent derailment or incoherence) which is a manifestation of formal thought disorder
grossly disorganized behavior (e.g. dressing inappropriately, crying frequently) or catatonic behavior
negative symptoms—e.g., affective flattening (lack or decline in emotional response), alogia (lack or decline in speech), avolition (lack or decline in motivation), anhedonia (lack or decline in ability to experience pleasure), social withdrawal (sometimes called social anhedonia). It should be noted that negative symptoms are different from symptoms of depression.
If the delusions are judged to be bizarre, or hallucinations consist of hearing one voice participating in a running commentary of the patient's actions or of hearing two or more voices conversing with each other, only that symptom is required to meet criterion A above. The speech disorganization criterion is only met if it is severe enough to substantially impair communication.
AND at some time during the illness there is either one, two or all three of the following:
major depressive episode
manic episode
mixed episode
B. During the same period of illness, there have been delusions or hallucinations for at least two weeks in the absence of prominent mood symptoms.
C. Symptoms that meet criteria for a mood episode are present for a substantial portion of the total duration of the active and residual periods of the illness.
D. The disturbance is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition.
[edit] Subtypes
Two subtypes of schizoaffective disorder exist and may be noted in a diagnosis based on the mood component of the disorder:
[edit] Bipolar type
if the disturbance includes
a manic episode
a mixed episode
Major depressive episodes usually, but not always, also occur in the bipolar subtype, however they are not required for DSM IV diagnosis.
[edit] Depressive type
The depressive type is noted when the disturbance includes major depressive episodes exclusively.
This subtype applies if major depressive episodes only (and no manic or mixed episodes) are part of the presentation.
