This address to the London Jewish Hospital Medical Society summarizes the mental conditions obtaining in nervous patients, and the methods available for their treatment. Stress is laid on the importance of a genuinely understanding attitude on the part of all concerned in the management of such patients, and on the advisability of doctors and nurses equipping themselves with a sound knowledge of unconscious mental processes. Analysis is the preferred method of treatment. 'When this is not feasible … the physician's intelligence … must be employed to guide his patient to a measure of mental wholeness.'
