The onset of Munchausen's syndrome.

Although Munchausen's syndrome is well known, its mode of onset and development are poorly understood. The authors describe an individual whose developmental history was notable for dyslexia and pathological lying from early childhood, and who later developed Munchausen's syndrome following an explosive separation from his terminally ill father. The patient's simulated genitourinary problems related directly to his father's renal malignancy. The development of his Munchausen syndrome is discussed with reference to his traumatic separation from his father as well and to his preexisting character pathology and probable central nervous system dysfunction.
