Undifferentiated schizophrenia for Harold; schizophreniform disorder for Tanya.
Step-by-step explanation:
Schizophreniform disorder is a mental disorder diagnosed when symptoms of schizophrenia are present for a significant portion of the time at least a month, but signs of disturbance are not present for the full six months required for the diagnosis of schizophrenia. In schizophreniform disorder, the symptoms (including prodromal, active, and residual phases) must last at least 1 month but not more than 6 months.
While Undifferentiated-type schizophrenia is a classification used when a person exhibits behaviors which fit into two or more of the other types of schizophrenia, including symptoms such as delusions, hallucinations, disorganized speech or behavior, catatonic behavior.
