Which is NOT one of the five types of schizophrenia?

Histrionic is not one of the five types of schizophrenia because it refers to a personality disorder characterized by excessive emotionality and attention-seeking behaviors, rather than a type of schizophrenia. The five recognized types of schizophrenia in the DSM-IV were Paranoid, Catatonic, Disorganized, Residual, and Undifferentiated.

In terms of understanding schizophrenia, each recognized type has distinct features:

• Paranoid schizophrenia is primarily characterized by the presence of auditory hallucinations and delusions of persecution or grandeur.

• Catatonic schizophrenia includes severe disruptions in motor behavior, ranging from extreme agitation to immobility.

• Disorganized schizophrenia involves disorganized speech and behavior, and flat or inappropriate affect.

Recognizing the specific classifications within schizophrenia is essential for diagnosis and treatment, while Histrionic traits belong within the spectrum of personality disorders, highlighting the importance of differentiating between the categories of mental health conditions.
