A twenty-seven-year-old man incurred a second acute schizophrenic breakdown characterized by aggressive fantasies toward pregnant women and toward men. These related to his rivalry with his younger sister and with his father. His great ambivalence toward his mother was associated with his passive dependent needs. He developed marked symptoms of parkinsonism during his hospitalization. These were apparently precipitated by his mother's visits, when she cuddled him like an infant. The parkinsonism acted as a defense against his hostility toward his mother and as a means of perpetuating the gratification of his mother's cuddling.
