26. Schizophrenia: Symptoms
In this module, mental health professionals observe a patient named Jerry, a classic schizophrenic.

Prominent psychiatrists describe schizophrenia and the prognosis for those diagnosed with this disease; a locked psychiatric ward provides a graphic illustration.
27. Schizophrenia: Etiology
This module covers the history of attitudes, beliefs, and theories about the etiology of schizophrenia. While the illness was long thought to be environmentally caused, this module emphasizes the scientific evidence in support of its organic origins. Dr. Arnold Scheibel of UCLA Medical Center describes cellular pathology in the hippocampus and speculates on the possible role of viruses. A genetic component is also demonstrated.
This module opens with statistics and a description of autism and how the disorder has been viewed historically. Studies now support the theory that autism results from a lack of normal neural growth during prenatal development. Dr. Temple Grandin of Colorado State University, severely autistic as a child, is presented as someone who overcame her autism and managed to use her way of perceiving the world to her advantage.
