He tells the clinician the he has been feeling apprehensive and edgy for the last month, but so far his anxiety hasn’t interfered with his job or home life. Doris feels terrified every time she leaves her house, and avoids doing so whenever possible. Kate constantly thinks about jumping in front of an oncoming car when she is walking. The only way she seems to be able to stop these self-destructive thoughts is to say Mother Goose nursery rhymes over and over to herself. Laura takes over 40 different vitamins and herbal remedies each day to keep herself in top physical health. Recently she had some severe dizziness, but her family doctor assured her that is was just a minor ear infection that would clear up in a few days. Laura is concerned because she is sure the ear infection is the sign of something much more serious, such as a brain tumor, and she has made appointments with three different specialists to have more testing done. 3.

She plans everything sown to the last detail and becomes very upset if things don’t work out the way she has planned. In the past 9 months Andrew has been fired by three different employers. He was unreliable and often missed work, and each employer finally let him go when they found he had been stealing money and materials. Andrew feels no remorse over his actions, but he has managed to convince each of his former employers that he is sorry for his actions, and none plan to press any charges. Ellen is has been feeling both depressed and anxious. She would like to be in a relationship but feels that it is out of her reach. She becomes unbearably anxious in new social situations and does not see how she will ever be able to approach or speak coherently to someone of the opposite sex. Roy alternates between periods in which he remains motionless and seems oblivious to his environment, and periods of hyperactivity and frenzied excitement. He seems to be responding to voices in his head. 4. Movie • “Home Videos and Schizophrenia” – Can we learn to predict who will develop schizophrenia?
